EXECUTIVE SUMMARY

Introduction Sound system planning is essential to provide management with guidance to economically develop the electric system for Utilities Commission, City of New Smyrna Beach (UCNSB) to ensure adequate and reliable service at the lowest cost to customers. The planning should provide for an orderly development of the system such that the new investment in facilities is in step with load growth and revenue. System planning should include the following:

Improvement of the quality of service to customers as improvement opportunities occur.

Expansion of the existing system to meet future load growth beyond the present design requirements.

Economic evaluation of the construction of new facilities to meet the required capacity.

By using this approach, interim changes and system additions will be compatible with the capacity level needs as system load growth occurs. To maintain a reasonable economic balance in system planning, the three main components of the system - power supply, transmission, and distribution - should be evaluated.

Expected growth in the service area will create a greater demand for UCNSB. Along with maintaining existing customers, this anticipated growth has led UCNSB to desire an assessment of their long-term system requirements based on a 10-year planning horizon. Also, a 5-year construction plan has been developed based on the recommendations established from the long-term analysis. Included in this report are the following:

Summary of the basic data, criteria, and assumptions used to evaluate the system

Analysis of the existing electric system to determine current and future deficiencies

Comparison of alternative solutions to the identified deficiencies

Development of a 10-year expansion plan of the electric system

Development of a 5-year construction plan

Cost estimates for the 5-year capital requirements to achieve the construction plan

Purpose of Report The purpose of this Electric System Transmission and Distribution Planning Study is to identify system improvements for the planning period based on the long-range system requirements. This plan will make allowances for changes that have occurred, and will prepare the system for the future by the timely installation of facilities, as needed, to provide sufficient and reliable service to UCNSB’s customers. Construction costs will be estimated by year for the financial forecast. Periodic reviews of the construction plan and the long-range system goals will be required to examine the applicability of the preferred plan considering actual system developments.

Summary of Report, Conclusions, and Recommendations Planning criteria were developed in Section 1, based on UCNSB’s system reliability and performance goals. The existing UCNSB electric system was analyzed and the findings are detailed in Section 2. Section 3 presents potential alternatives to serve the future planning load; alternatives were developed to keep costs down and quality high. Section 4 summarized the preferred alternatives and the 5-year construction plan.

The UCNSB system was analyzed to serve a projected 5-year system summer peak demand of 110.2 MW. The system load was allocated to areas based on UCNSB staff’s knowledge of the area. Based on these analyses, the 5-year construction plan and the 10-year long range plan includes the following:

Short Term Project (Load Levels 1 and 2):

• At Smyrna Substation, replace (3) single-phase 576 kVA regulators with (3) single-phase regulators of matching impedance, and replace relaying with Microprocessor relays.

• Construct a 115 kV transmission line between Airport and Field Street Substations to complete the loop. Follow the railroad Right of Way for approximately 3.6 miles.

• Bus work at Field Street Substation to move Line 4 to the new transformer.

• Convert various 13 kV taps to 22.9 kV.

• Construct a new circuit to the island using Field Street Substation existing distribution routes.

• Use the spare bay at Airport Substation to build a new feeder.

• Various distribution improvements to relieve loading and improve conditions for contingency switching.

Medium Term Projects (Load Levels 3 – 5):

• Install a new 115-22.9 kV, 18/24/30 MVA transformer with Load Tap Changers at Airport Substation.

• Construct a new circuit to the island using Airport Substation existing distribution routes.

• Various distribution improvements to relieve loading and improve conditions for contingency switching.

Long Term Projects (Load Levels 6 – 10):

• Eliminate and remove the Schoolway step-down substation.

• Convert various 13 kV taps to 22.9 kV.

• Various distribution improvements to relieve loading and improve conditions for contingency switching.

To determine the cost of system improvements for the UCNSB electric system over the next 10 years, expenditures required to serve projected loads as a result of customer growth were estimated for each year. The projected capital requirements are as follows:

Table ES-1 Electric System Improvements

Timing Year Capital Requirements (2006 Dollars)

Short Term 2006 - 2007 $3,681,150

Medium Term 2008 - 2010 $3,166,480

Long Term 2011 - 2015 $2,330,760

TOTAL $9,178,390

General Basis of Study The projected system peak load and number of customers served used in the report were based on the load forecast prepared by R. W. Beck, Inc, and UCNSB’s management and staff. A copy of the system forecast is given in Exhibit 1.

An analysis, using as a basis the design criteria herein, of conductor loading, voltages, physical conditions and reliability, was performed on all of the substations, transmission and distribution lines, and major equipment of the existing system. Milsoft Integrated Solutions, Inc.’s Windmil version 7.1 software was used to analyze the transmission system and distribution circuits. The criteria given in Section 1 form the basis of this analysis. New distribution and power supply construction

requirements were considered simultaneously as a “one system” approach to produce an orderly and economical development of the total system.

In the preparation of this Report, including the opinions contained herein, we have made certain assumptions and used certain considerations with respect to conditions that may occur in the future. While we believe these considerations and assumptions are reasonable and reasonably attainable based on conditions known to us as of the date of this Report, they are dependent on future events. Actual conditions may differ from those assumed herein or from the assumptions provided by others; therefore, the actual results will vary from those estimated. In addition, field conditions encountered during design may impact some of the projects.

SECTION 1 BASIC DATA AND ASSUMPTIONS

1.1 Operating System Statistics Utilities Commission, City of New Smyrna Beach (UCNSB) provides service to approximately 22,000 customers located within and around the city limits of New Smyrna Beach, Florida. UCNSB owns and operates 4 distribution substations, including three 23 kV substations and one 13 kV substation.

The distribution substations serve 11 feeders with approximately 225 miles of overhead line and 88 miles of underground line. Ten of the feeders are constructed for and operated at 22.9 kV, and one feeder is operated at 13.2 kV. Installed overhead conductor sizes range from #6 Cu to 652 AAAC and underground conductors from 1/0 AL to 1000 MCM Cu.

UCNSB has three 115 kV transmission delivery points. Two are from Florida Power & Light (FP&L) and the third is from Progress Energy (PE). All three points tie into a ring bus at 115-23 kV Smyrna Substation. From Smyrna Substation, 115 kV transmission, owned and operated by UCNSB, is tied into Field Street and Airport Substations as radial feeds.

Diesel generation facilities are also available for UCNSB, and there are three sites within the city. Although, for the purpose of this study, no generation is assumed to be in use during peak loading.

1.2 System Planning Load In 2006, a system load forecast (2006 Load Forecast) was prepared by R. W. Beck, Inc. (R. W. Beck), with the assistance of UCNSB management and staff. The 2006 Load Forecast consists of projections of residential customers, sales by major rate classification, and system peak demand for the period 2006 through 2025. The forecast relies on monthly utility sales, energy requirements, and demand data provided by UCNSB staff. Historical and projected economic and demographic data were provided by Economy.com, a nationally-recognized provider of such data. R. W. Beck has also relied on information regarding planned and expected residential and commercial developments maintained by UCNSB staff. Weather data for Daytona Beach International Airport, the closest “first-order” weather station to New Smyrna Beach, was provided by the National Oceanic and Atmospheric Administration (NOAA).

The results of the Forecast imply that system net energy for load (NEL) and peak demand are expected to grow at an annual average growth rate of 3.6% over 2006-2015 and 2.6% over 2016-2025. On a normal weather basis, the system NEL and

Page 14: Electrical System Planning Study

Section 1

1-2 R. W. Beck G:\5738\01015\Work Products\Report\Final UCNSB T&D Studyv2.doc 5/10/06

peak demand for 2006 are projected to be 414.8 GWh and 97.7 MW, respectively. This reflects a 48.5% annual peak load factor, which is similar to the average load factor experienced over the last 10 years. While the system has peaked variably in the summer or winter, depending on weather conditions, the 2006 Load Forecast reflects that the system is typically winter-peaking, although by a small margin. The system NEL and peak demand for 2010 are projected to be 490.4 GWh and 115.5 MW, respectively, representing growth over the 5-year planning period (from 2005) of 24.5 MW.

Although the UCSNB distribution system is primarily winter peaking by a small margin, for the purposes of the study, the summer peak loading conditions have been evaluated. Capacity limitations due to heating on distribution equipment arise during summer conditions. Therefore, the system has been evaluated for projected 2010 summer peak load of 110.2 MW to better assess the equipment capacity with existing and projected summer loads.

UCNSB plans to construct and maintain an electric system that can provide adequate and reliable service during summer peak load periods. All assumptions and the resulting forecast were approved by UCNSB before system analysis was initiated. A summary of data used to develop the load forecast is given in Exhibit 1 of this report.

The 2006 Load Forecast projects load levels for specific years. However, it should be recognized that loads may develop more quickly or more slowly than anticipated. Accordingly, UCNSB should consider any recommendation to build facilities to be related to a particular load level rather than a particular year. To avoid the impression that facilities need to be constructed for a specific year versus a specific load level, the remainder of this report refers to load levels and the anticipated years. UCNSB should maintain flexibility, to the extent possible, with respect to its facilities construction program to respond to load growth as it unfolds over time and modify peak demand projections periodically.

Table 1-1 is a presentation of the historical and projected system NEL and peak demand through Load Level 10 of the system’s coincident substation peak demands.

1.3 Load Allocation The service area was reviewed with management and staff of UCNSB relative to potential load growth. Each substation area was examined based on historical load growth and load growth potential to establish relative growth factors which are summarized in Table 1-2. The relative growth factor provides a sense of how a substation load is projected to grow relative to the average system growth which was assigned a relative growth factor of 1.0.

Table 1-2 Relative Substation Growth Factors

Substation Relative Growth Factor Field Street #1 1.75 Field Street #2 1.75 Airport 1 Schoolway (13 kV) 1 Smyrna 1

All of the UCNSB substations were assigned a relative growth factor of one, with the exception of the two Field Street substation transformers. The relative growth factor was applied to the base growth on each of the UCNSB substations. Estimated loads for known commercial and residential developments were developed and added to the engineering model and substation and feeder forecast as “spot loads”. The spot loads assigned to each of the substations accounts for a significant portion of the projected load. For the majority of the system, the base load growth without spot loads is expected to be nearly even across the system. However, higher expected growth is expected to occur on the Field Street Substation, which has a relative growth factor of 1.75. The substation and feeder forecast, presented in Exhibit 2, illustrates the total projected load and identifies spot loads and base growth on the UCNSB system.

New distribution facilities to serve industrial loads, such as factories, cannot be accurately planned for because of the varying load requirements. Normally dis-tribution facilities are constructed to serve the industrial customer without affecting the overall planned distribution upgrades; such customers often require their own distribution and substation facilities.

1.4 Distribution Voltage Drop For the design load, a 5% voltage drop was assumed to be the maximum allowable voltage drop from the substation to the end of the distribution feeders or between distribution line regulator stations. The voltage drop calculations assumed a sub-station bus voltage of 124 volts and a 120 volt base.

Page 17: Electrical System Planning Study

Basic Data and Assumptions

G:\5738\01015\Work Products\Report\Final UCNSB T&D Studyv2.doc 5/10/06 R. W. Beck 1-5

1.5 Substation Voltage Regulation Voltage regulation was assumed for each substation such that a voltage drop could be experienced on the transmission system and, at peak loads, 124 volts could be supplied from the substation secondary bus. Any proposed substations were assumed to contain transformers with load tap changers or station regulators.

1.6 System Power Factor Specific capacitor locations cannot be identified to compensate for future reactive demand until the load develops. It was assumed that UCNSB will require additional capacitor installations in the future to maintain a 95% power factor at the substation to provide quality power to its customers and limit system losses.

1.7 Transmission and Distribution Line Routing When transmission and distribution lines were assumed to be constructed or converted to a larger conductor size, economic conductor sizes were selected. Existing transmission and distribution line routing was planned to be used where possible. Environmentally sensitive areas were considered, and in cases where new transmission and distribution lines were required, such areas were avoided or routes were selected to minimize the impact of the lines.

1.8 Reliability Single-contingency planning is generally used for providing reliability where appropriate. Such planning assumes facilities are installed to provide adequate service with any one substation transformer or transmission line out of service.

Smyrna, Field Street, and Airport substations are served via 115 kV transmission. Smyrna Substation has 115 kV feeds from Volusia, Edgewater, and Cassadaga. Field Street, and Airport substations are served as radial feeds from Smyrna Substation.

Based on the current location and configuration of the substation transformers, Smyrna and Airport Substations have single transformer capacity; therefore, firm transformer capacity is not available at these locations. Firm capacity exists at Field Street Substation where there are three transformers and at Schoolway Substation, where there are two transformers.

For the purposes of this study, planned loading on substation transformers is limited to 100% of the maximum nameplate rating at 55° C rise. In most areas of the system, UCNSB depends on having the capacity available to transfer load through the distribution system to other substations if a substation transformer is out of service. To allow for transfer capacity, planned loading on distribution tie lines is limited to 50% of the rated capacity. For all other primary distribution lines, conductor loading is limited to 80% of capacity.

Single-phase loading was also limited to 50 Amps to indicate where multi-phasing would benefit UCNSB base on the following widely accepted practices among electric utilities:

Multi-phasing reduces the number of customers served per phase, thus improving reliability.

Multi-phasing reduces line currents, which significantly reduces losses.

Balancing loads on backbone circuits is more difficult with heavily loaded single-phase lines, which increases losses.

In some cases, the outage of a heavily loaded single-phase tap can produce nuisance trips of up-line protective devices, resulting in unnecessary outages.

Protective devices sized for heavily loaded single-phase taps are more difficult to coordinate with up-line devices.

In areas where more than 50 amps of load are served from a single-phase line, up-grade to three-phase was recommended in order to provide greater reliability and improve load balance. Thus, line conversion from single-phase to three-phase was assumed where the load exceeds approximately 661 kW at 13.2 kV.

1.9 Financial Criteria 1.9.1 Inflation Prior to developing economic study rates for specific application to the construction of an electric system, a general inflation rate was assumed to provide a common basis for developing the remainder of the economic study rates. Based on Blue Chip Economic Indicators, a general inflation rate of 2.4% was used for the study period. This was applied to the projected cost of capital expenditure for construction in the 10-year plan.

Inflation rates varied for Operation and Maintenance and Insurance expenditures. Based on a review of the expected expenses for the UCNSB Electric System for fiscal years 2007 - 2016 and discussions between UCNSB staff and R. W. Beck, Inc., an inflation rate of 6.9% was used for O&M expenses on the distribution system. For insurance expenditures, an inflation rate of 2.0% was used in the analysis.

1.9.2 Cost of Capital The interest rate, or cost of capital, is defined as the rate paid for long-term debt to finance capital improvements. UCNSB’s current cost of debt is 5.0%. This rate was used for the present worth discount factor to determine the equivalent cost of future expenditures in today's dollars. The present worth cost method allows various alternatives with different timing of future expenditures to be economically compared to determine the least cost alternative.

1.9.3 Annual Fixed Charge Rates The annual fixed charge rate, when applied to the initial plant investment, gives the annual revenue requirement for operating and maintaining the system. The annual fixed charge rate components – operation and maintenance, depreciation, insurance, and cost of capital - were provided by UCNSB from historical data, where available. Operation and maintenance expenses were available for distribution and transmission, only. Therefore, an industry average rate of 3% was assumed for substation O&M. The remaining component, the annual depreciation rate, is based on an equipment life for transmission of 40 years, substations of 40 years, and distribution of 33 1/3 years. The annual fixed charge rates used in the analysis are summarized in Table 1-3.

Table 1-3 Annual Fixed Charge Rates (%)

Plant Item Transmission Substation Distribution

Cost of Capital 5.00% 5.00% 5.00% Depreciation 2.50% 2.50% 3.00% Operation and Maintenance 5.30% 3.00% 5.00% Insurance 0.50% 0.50% 0.50% Total 13.30% 11.00% 13.50%

1.9.4 Cost of Power The cost of power for UCNSB is a blend of the cost of local generation and power purchased from outside sources. The cost of power for 2005 was $0.04735 per kWh, based on information provided by UCNSB. It is anticipated that trends for the current market such as investments to meet clean air regulations and higher fuel costs will impact power costs during the planning period. Based on a review of the expected expenses for the UCNSB Electric System for fiscal years 2007 - 2016 and discussions between UCNSB staff and R. W. Beck, Inc., power costs were assumed to increase 8.6% per year for the study period.

1.9.5 Cost of Losses Based on the existing power rates for calendar year 2005, the annual cost of load losses was calculated at $111.12 per peak kW of loss. A three-year average annual load factor of 47.8% was derived from the demand and energy information given in the Annual Reports, and included in the calculation of cost of losses. The calculation of the cost of losses is given in Exhibit 3.

1.11 Economic Conductor Selection Economic conductor selection includes the consideration of initial construction costs and the associated losses of the selected conductors. For two alternative conductors compared, there is generally a kW load at which the fixed costs associated with the construction plus the variable costs related to line losses are equal for both alternatives. For loads less than the equal cost load, the smaller conductor should be selected and for loads greater than such load, the larger conductor should be selected. There are many choices of conductor sizes, but as part of system operation, standard conductor sizes for overhead distribution construction of #2 AAAC, 397 AAAC, and 652 AAAC have been selected by UCNSB. Standard conductor sizes for underground distribution construction are #1/0 AL, #4/0 AL, and 500 MCM CU.

Since a distribution line is used for many years, economic conductor selection should include the consideration of the initial load, load growth, cost of losses, increases in power cost, the annual fixed cost and the present worth cost of the dollars spent (PWC). The load was expressed as the current annual peak load on the distribution line considered and assumed to grow over the thirty-three year life cycle analyzed. The cost of power was assumed to stay constant and a thirty-three year present worth factor was developed for the cost of losses and for the annual fixed cost.

Two basic alternate conditions are compared. The first, and most often encountered condition, is the timing of the conversion of an existing distribution line. Economic change-out occurs when the costs associated with the new line are lower than the variable costs associated with the existing line.

Based on economics alone, the existing distribution line should remain as long as the annual cost of losses is less than the annual cost of losses plus fixed costs on the new line. Economic conductor selection analyses were performed and a summary was prepared for new construction and change out as described below.

The second condition arises when a new line is to be constructed or an existing line must be changed for reasons other than economic conductor selection. Such conditions include voltage drop, system changes, and reliability. Often the need to reconductor is caused by voltage drop problems before there is an economic advantage associated with increasing the conductor size.

In some applications, spacer cable construction is required due to reduced code clearance or right-of-way. Conductor sizing for these applications will be based on projected load and manufacturer’s ratings.

General guidelines were developed based on the following assumptions:

Compound annual load growth – 3.56%

Annual cost of peak kW loss - $111.12

Fixed cost factor – 13.5%

Present worth discount factor – 5.0%

The following general guidelines were developed for 22.9/13.2 kV overhead distribution lines based on the analysis described above:

New single-phase overhead distribution lines should generally be constructed with #2 AAAC. (Loads less than 661 kW). New single-phase underground distribution lines should be constructed with #1/0 AL.

New three-phase overhead distribution lines should be constructed with the specified conductors at the initial load given as follows:

For loads less than 360 kW: #2AAAC

For loads greater than 360 kW and less than 1,725 kW: 397.5 ACSR

For loads greater than 1,725 kW: 652 AAAC

The single-phase lines should be reconductored to three-phase wherever needed based on operating conditions and voltage drop.

Existing three-phase overhead distribution lines that need to be upgraded should be reconductored with the specified conductors at the initial load given as follows:

For loads less than 430 kW: #2AAAC

For loads greater than 430 kW and less than 1,725 kW: 397.5 ACSR

For loads greater than 1,725 kW: 652 AAAC

Economic conductor selection curves are graphically presented in Figures 1-1 through 1-2 for overhead distribution. The economic conductor selection curves and guides should be updated to reflect current construction and power costs each time the Electric System Study is reviewed.

1.12 Computer Model of System The New Smyrna Beach electric transmission and distribution system was modeled on Milsoft Integrated Solutions, Inc.’s Windmil version 7.1 software. Upon completion of the model, metered feeder loads were distributed to each line section of the computer model based on the line section's connected transformer kVA compared to the total connected transformer kVA on the feeder.

This method of allocating loads assumes that a customer's kW demand on peak was in proportion to the transformer kVA serving the customer. Adjustments to the distributed load were made to industrial customer peak kW demands if they were known.

Spot loads, or specific expected developments on the distribution system, were also applied to the engineering model. These loads were provided by UCNSB staff and the projected loads were entered at their specific locations in the model.

After kW loading of line sections was established, the load flows for each feeder were prepared. The load flows provided information such as the percent conductor loading to its capacity, calculated line losses, power factor information, and voltage drop along line sections. The load flow information from the computer model was compared to the conductor loading, single-phase loading, and voltage drop criteria as outlined in this Report. Recommendations were then based on these results.

1.13 Distribution Line Ratings Overhead distribution line ratings in Table 1-6 are based on lines designed for 75°C (167°F) conductor temperature at 37.8°C (100°F) ambient temperature and 2ft./sec. wind. To allow for transferring load between circuits in the distribution system, the loading on three-phase tie lines was limited to 50% of the summer conductor rating. Less extreme weather conditions or lines designed for greater than 167°F conductor temperature may provide additional line capacity; lines designed for a lower conductor temperature may provide less capacity.

Section 2 ANALYSIS OF EXISTING SYSTEM

2.1 Existing Load Analysis 2.1.1 Substation Capacity The Utilities Commission City of New Smyrna Beach (UCNSB) electric system has 4 substations. All of the substations are served at 115 kV via the 115 kV ring bus at Smyrna Substation, which is served from two Florida Power & Light (FP&L) and one Progress Energy (PE) transmission connections. The rated capacity and voltage of the distribution substations are listed in Table 2-1.

The historical substation loading is given in Table 2-2. In the current configuration and location of the substation transformers, the total installed 23 kV and 13.2 kV substation transformer capacities are approximately 120.0 MVA and 40.0 MVA, respectively. At the existing summer peak, none of the substation transformers exceed capacity.

2.1.2 Substation Reliability UCNSB’s design criteria do not require firm capacity at each distribution substation. Outage history and customer response have not mandated that level of reliability or justified the cost. In the existing location and configuration of the UCNSB substation transformers, only Field Street and Schoolway Substations have firm capacity available. Others rely on distribution ties or a mobile transformer, if available. For the study, substation power transformers are limited to 100% of the maximum nameplate rating at 55° C rise.

2.1.3 System Power Factor Analysis UNCSB does not currently incur penalties for power factor. Capacitors are placed on the system based on peak feeder readings. A power factor less than 90% is a flag to install a capacitor bank size for a correction to 95% power factor.

2.1.4 Distribution Circuit Analysis Voltage drop and load flow calculations were made with Milsoft Integrated Solutions, Inc.’s Windmil version 7.1 software assuming load allocations based on connected kVA in individual line sections for the 2005 summer peak. The load flow results of the distribution system are summarized in Exhibit 6 for the existing and future loading conditions including the 5-year load level ("LL05") and the 10-year load level ("LL10"). A review of the information contained in this exhibit provides a brief, but comprehensive, understanding of potential deficiencies in the existing distribution circuit capacities and service voltage conditions. The voltage conditions are calculated on a 120 volt base and include the effects of voltage regulation due to capacitors and line regulators.

The calculated load capacities for each conductor are given in Table 1-6 and Table 1-7. Generally the main feeder conductor cannot be loaded to 100% of its rated capacity. Before the 100% conductor loading is reached, unacceptable voltage levels often will be experienced on tap lines and near the end of the feeder.

For planning purposes, the conductor loading was limited to 50% of the calculated capacity on three-phase tie lines to allow for load transfer on the distribution system. All other conductors are limited to 80% of peak thermal rating.

Based on the distribution system model, each of the 11 circuits was analyzed with respect to adequate voltage and loading conditions. The computer analysis at the 2005 peak load level for the 11 circuits revealed that:

Sections of the following circuit(s) exceed 6 volts drop

Field Street – Line 5, Line 7

Schoolway – Line 14

Smyrna – Line 11

Sections of the three-phase feeders on the following circuit(s) exceed 50% of the conductor ratings

Airport – Line 15, Line 17

Field Street – Line 5, Line 7

Schoolway – Line 14

Smyrna – Line 11

Sections of the following circuit(s) have single-phase taps loaded greater than 50 amps.

2.2 Projected System Analysis 2.2.1 Substations The projected system loads were allocated to the distribution substations as shown in Exhibit 2. The rated transformer capacity, in the existing configuration and location of the transformers, was compared to the projected substation loads to identify the load level in which the load would exceed the capacity. Identified substation deficiencies at the projected loads include:

Field Street – Transformer #1 – Exceeds 100% of capacity in LL3

Smyrna – Exceeds 100% of capacity in LL4. Note: Field Street Transformer #3 will be installed in the fall of 2006, which will serve some of the Smyrna Substation existing and projected load. Therefore, the Smyrna Substation will not exceed capacity during the planning period.

2.2.2 Distribution System Exhibit 6 shows the distribution deficiencies for the existing system at the 5 and 10 year loads. The deficiencies were identified after the existing system model was adjusted to reflect the projected growth.

As shown in Exhibit 6, of the 13 circuits analyzed at Load Level 5:

5 circuits exceed 5% volts drop.

7 three-phase feeders exceed 50% of the conductor ratings.

3 feeders have single-phase taps that are loaded greater than 50 amps.

At Load Level 10:

5 circuits exceed 5% volts drop.

7 three-phase feeders exceed 50% of the conductor ratings.

4 feeders have single-phase taps that are loaded greater than 50 amps. Recommended system improvements to address these problems are included in the Appendices for each alternative. Alternatives are defined in Section 3.

Section 3 ALTERNATE PLANS

3.1 Exploratory Plans Various system expansion plans can adequately serve the projected load. The purpose of this section is to detail the alternative plans investigated and to identify a recommended plan that will adequately serve the customers' present load, the load as the system expands, and the planning load selected. To identify the recommended plan, criteria were developed in Section 1 to select and economically compare the alternative expansion plans.

To improve transmission reliability, three transmission routes for a 115 kV tie between Field Street and Airport substations were evaluated. New construction and system upgrades were developed jointly with the UCNSB staff to address substation and distribution system deficiencies and reliability issues and are detailed in Section 4. The substation and distribution projects were combined with each of the transmission alternatives, and evaluated on a 20-year present-worth cost basis.

3.2 Methodology After the alternatives were identified through discussions among the UCNSB management and staff and R. W. Beck, Inc., the analysis for each alternative was prepared as follows:

Proposed improvements were modeled and computerized load-flow, voltage-drop, and loss calculations were prepared to determine whether each alternative provided adequate service to the customers.

Transmission, substation, and distribution cost estimates were prepared for initial capital costs and cost of losses. Other applicable costs were also estimated for each alternative.

The estimated substation cost estimates are given in Exhibit 5.

The project descriptions and estimated construction costs are given in Appendices A through C for the respective alternatives.

A present-worth comparative cost summary was prepared for each alternative. The assumptions used in the present-worth analyses are summarized in Exhibit 4. The present-worth calculations are given in Appendices A through C for the respective alternatives.

Also, this project includes the construction of a new circuit to the island from Line 16.

On HWY 1, between N. Orange St. and Park Ave., use Line 4’s express circuit to serve the island through Line 16. Switch the connection at this location. Also, at Turnbull Bay Rd and HWY 1, where Line 16 currently connects to the circuit traveling north, south, and east onto Tanglewood Ave., disconnect Line 16, and connect to the existing Line 4 circuit traveling north and south on HWY 1. To complete the transfer, at Industrial Park Ave. and HWY 1, where Line 4 currently travels north up HWY 1 to serve Inlet Shores, transfer that tap to the Line 16 feed that dead-ends there.

The total transfer from Line 16 to Line 4 is approximately 1.9 MW. This unloads Line 16 to allow it to be utilized to serve the island.

Project Number 20 (continued; part 2 of 3)

On Line 16, construct 1,700 feet of 23 kV double circuit 500 kCM CU underground submarine cable from SR 44 to Canova Dr at Oakwood to cross the causeway. There is an existing cable route at this location, but the cable in place is inoperable. Therefore, the new crossing will utilize the route, but the wire will be new. Costs assume that the new conductor will be plowed in conduit under the river bed. Cost for this portion of the project is approximately $400,000.

From the submarine cable crossing, construct 500 feet of 23 kV 652 AAC overhead conductor from Canova Dr to S. Peninsula at Oakwood on Line 16. Cost for this portion of the project is approximately $7,500.

Transfer the north tap on S. Peninsula at Oakwood from Line 7 to Line 16 to transfer approximately 9.7 MW of load.

Section 5 DEVICE COORDINATION REVIEW

This section describes the existing protective equipment on the electric distribution system for the Utilities Commission, City of New Smyrna Beach (UCNSB); evaluates the effectiveness of the existing equipment ratings, locations, and settings; supplements the existing protective devices by recommending new equipment; describes the recommended protection philosophy; and identifies the basis for setting and sizing protective devices to implement this philosophy.

5.1 Study Objectives The goals of distribution system protection are to minimizing public risk and equipment damage, while limiting any fault-induced service interruption to the fewest possible customers and the shortest possible duration. Not all interruptions can be prevented, but should be controlled and limited to the smallest practical portions of the system.

Several design considerations must be weighed against cost in devising a well-protected distribution system:

Public Safety – The protective devices should be able to detect the full range of available fault currents to minimize hazards to the public.

Equipment Protection – Damage to the distribution system equipment will be minimized with a well-designed protection scheme by limiting the fault duration.

Reliability – Proper coordination will provide critical information to the engineering staff and service crews regarding the location of the fault, thus limiting outage duration per customer, and event. Mis-coordination of protective devices can cause unnecessary device operations and outages, resulting in confusion and extensive delays in restoring service.

Power Quality – Minimize voltage deviation, which could result in failure or misoperation of the utility or end user equipment.

5.2 Protection Requirements Studies have indicated that between 80 to 90% of line faults are of a temporary nature. Therefore, the use of multi-shot devices will provide the opportunity to clear temporary faults from the system. As a result, these devices can increase reliability while providing protection. However, most faults internal to a substation are permanent in nature and do not warrant reclosing.

In performing these tasks, the protective equipment must first sense that an abnormal condition exists. In a distribution system, this usually means sensing larger-than-normal current flow. Then the equipment must act to separate the faulted equipment

Page 78: Electrical System Planning Study

Section 5

5-2 R. W. Beck G:\5738\01015\Work Products\Report\Final UCNSB T&D Studyv2.Doc

from the rest of the system. This is accomplished by either blowing a fuse or opening some type of fault-interrupting switch, usually a circuit breaker or line recloser.

It is desirable to remove the faulted equipment from the system quickly, both to limit damage to the faulted equipment and to minimize the disturbance to the remaining system. It is also desirable to sense precisely where the fault exists and to remove only the faulted equipment, so that the impact on customers is minimized.

Furthermore, the protective equipment should be extremely reliable: it should never operate when there is no fault, but it should never fail to operate precisely as intended when there is fault.

Finally, the cost of the equipment to perform these functions (capital, operation, and maintenance) must be reasonable relative to the overall costs of providing electric service.

It is obvious that there are inherent conflicts between the stated requirements. For example, faster equipment might not be as precise at locating faults. Less expensive equipment might exhibit a reduction in reliability. Therefore, it is necessary to arrive at a compromise that provides a satisfactory mix of speed, selectivity, and cost.

Even after the compromises have been made and protective equipment has been installed, the protective system is capable of operation in different modes, which vary the mix of speed, selectivity, reliability, and cost.

5.3 System Loads and Fault Current Calculations An engineering model using software by Milsoft, Windmil , was used to determine substation equipment loading, and the maximum and minimum fault currents on the system. Balanced load flows, based on the 90 MW summer peak for 2005, were selected to represent the system for the Master Plan analysis. The balanced load flows were compared to the continuous current rating of each overcurrent device.

Each substation was assumed to be an independent power delivery point. The complex source impedance at the 115 kV delivery point at Smyrna Substation was provided by UCNSB. The source impedances for the remaining substations were calculated using Aspen One-Liner based on the provided source impedance at Smyrna Substation. Voltage drop calculations assumed a substation bus voltage of 125 volts on a 120 volt base.

The Rural Utilities Service (“RUS”) recommends the following in Bulletin 61-2:

“Forty ohms is more conservative and is recommended for circuits from metering points, 24.9 kV distribution substations, and 12.5 kV substations with transformer capacity of 5,000 kVA and smaller. For circuits from 12.5 kV distribution substations rated larger than 5,000 kVA, 30 ohms may be considered for use as the value of fault resistances to calculate minimum fault current.”

Although UCNSB is not regulated by RUS, the guideline above remains an industry standard. For 13.2 kV Schoolway Substation, a fault resistance of 30 ohms for overhead and 20 ohms for underground distribution was assumed. The remaining

Page 79: Electrical System Planning Study

DEVICE COORDINATION REVIEW

G:\5738\01015\Work Products\Report\Final UCNSB T&D Studyv2.doc R. W. Beck 5-3

substations on the distribution system are operated at 22.9 kV. Therefore, a fault resistance of 60 ohms for overhead and 40 ohms for underground distribution at 22.9 kV was assumed. For the purpose of this study, no generation is assumed for load flow and fault calculations.

5.4 Existing System Configuration UCNSB has three 115 kV transmission delivery points. Two are from Florida Power & Light (FP&L) and the third is from Progress Energy (PE). All three points tie into a ring bus at 115-23 kV Smyrna Substation. From Smyrna Substation, 115 kV transmission, owned and operated by UCNSB, is tied into Field Street and Airport Substations as radial feeds. UCNSB owns and operates 4 distribution substations, including three 23 kV substations and one 13 kV substation. Diesel generation facilities are also available for UCNSB, and there are three sites within the city.

The distribution substations serve 11 feeders with approximately 225 miles of overhead line and 88 miles of underground line. Ten of the feeders are constructed for and operated at 22.9 kV, and one feeder is operated at 13.2 kV. Installed overhead conductor sizes range from #6 Cu to 652 AAAC and underground conductors from 1/0 AL to 1000 MCM Cu.

The existing distribution system includes fuses on many of the taps off of the backbone circuit and substation overcurrent relays. Line reclosers are also used by UCNSB. In most cases, the ground trip settings on the reclosers are bypassed. As a result, the existing scheme requires the substation relays to be the primary overcurrent protection device for the entire distribution circuit.

5.4.1 Source Impedance and Transformer Data Each substation was assumed to be an independent power delivery point in the Windmil model. The complex source impedance provided by UCNSB is given in Table 5-1. Table 5-2 lists the substation transformer nameplate data provided by UCNSB. The calculated faults at each substation based on the distribution system model are summarized in Table 5-3.

5.4.3 Substation Overcurrent Protection Substation relay data was provided by UCNSB. Both electromechanical and electronic relays are utilized at the UCNSB substations. The relay manufacturers include ABB and General Electric.

The existing substation overcurrent protective devices and settings were evaluated based on available faults calculated in the Windmil model (see Table 5-3), and the existing system configuration provided in substation one-lines and distribution maps.

5.4.4 Line Reclosers Line recloser data provided by UCNSB is summarized in Table 5-5. Based on this information, the majority of the line reclosers do not have ground trip settings; therefore, the existing scheme requires the substation ground relays to provide the primary overcurrent protection for the entire distribution circuit.

The existing substation overcurrent protective devices and settings were evaluated based on available faults calculated in the Windmil model, and the existing system configuration provided in distribution maps.

5.4.5 Fuses The existing fuses were evaluated based on available faults calculated in the Windmil model, and the existing system configuration provided in the distribution maps.

Types – The existing fuses were included in the distribution system model based on the distribution maps provided by UCNSB. According to UCNSB staff, T-type fuses are utilized for overhead taps and K-type fuses are utilized for underground risers and cabinets.

Fuse Fault Duty – The maximum rating of the cut-outs used by UCNSB is unknown. For the purposes of this analysis, the maximum rating was assumed to be 10,000 Amps for all fuses. The calculated maximum fault should not exceed the interrupting rating of the fuse and holder. Fuse holders with higher fault ratings should be installed where the maximum available fault currents exceed the duty rating of the existing holder. The calculated faults for the distribution system did not exceed the assumed rating for the fuse cut-outs of 10,000 Amps.

5.4.6 Review and Maintenance Periodic reviews are recommended in order to locate potential coordination problems that can result from load growth or changes in the system characteristics. Also, a maintenance program should be considered to ensure proper operation of the relays, breakers, and reclosers associated with the protection system.

5.5 Conclusions and Recommendations Changes to the existing overcurrent protection scheme were recommended based on the assumptions and analysis contained within this document. A summary of the analysis, conclusions and recommendations is given below. The recommended relay settings are given in Exhibit 7 and TCC charts for the recommended protection scheme is given in Exhibit 8.

• On Line 15, the existing settings for recloser R104 have been evaluated and approved. Down-line of recloser R104, a 30K or a 20T is the optimum fuse size that provides the proper coordination.

• On Line 16, recloser R231 should be relocated from its existing location up-line on Industrial Park Ave. to U.S. 1, and a fast phase operation should be added to the recloser. The relocation is recommended due to the fact that the recloser is very close in series with a fused underground section of the Industrial Park. Once the recloser is moved, it will provide sectionalizing and protection for the whole tap instead of the underground area only. Down-line of recloser R231, a 50K or a 30T is the maximum fuse size that provides the proper coordination.

• On Line 16, the existing settings for recloser R216 have been evaluated and approved. Down-line of recloser R216, a 50K or a 30T is the maximum fuse size that provides the proper coordination.

Fuse Size – The location of the existing fuses was based on the distribution model. Fuses larger than an 80K or an 80T do not coordinate fully with the recommended feeder relay settings.

Note: If currently un-fused, the Tinoia Rd. tap on Line 17 should be fused to help with sectionalizing.

Series Fuses – Down-line of an 80K, a 40K or a 25T provides proper coordination up to 1,890 A or 1,640 A, respectively. Likewise, down-line of an 80T, a 40T or a 65K provides proper coordination up to 3,270 A or 3,670 A, respectively. The following illustration, Figure 5-1, is a snapshot from the engineering model. It presents the maximum fault current ranges on the Airport Substation in which the fuses in series will coordinate.

Line Reclosers – The following reclosers are located on Field Street Substation feeders, and recommendations include:

• Optional: On Line 3, install a 3-phase recloser down-line of the submarine cable to improve sectionalizing of faults that occur on the island and to reduce stress on the submarine cable.

• On Line 3, the existing settings for recloser R105 have been evaluated and approved. Down-line of recloser R105, a 25K or a 15T is the optimum fuse size that provides the proper coordination.

• On Line 4, for recloser R215, the C-curve on the slow curve should be changed to a B curve to increase the margin of operating time between the recloser slow phase response and the up-line relay. Down-line of recloser R215, a 50K or a 40T is the maximum fuse size that provides the proper coordination.

• Optional: On Line 5, install a 3-phase recloser down-line of the submarine cable to improve sectionalizing of faults that occur on the island and to reduce stress on the submarine cable.

• On Line 7, a slow ground response should be added to recloser R213 to detect the minimum fault down-line of the relay. For recloser R213, a 50K or a 40 T is the maximum fuse size that provides the proper coordination.

• On Line 7, the slow ground curve of recloser R226 should be adjusted to provide better coordination with larger fuses. For recloser R226, a 40K or a 20T is the maximum fuse size that provides the proper coordination.

• On Line 7, reclosers R237 and R259 are presently in series and do not coordinate properly for the full range of available faults. Recloser R237 should be relocated to the north side of the 1-phase recloser R259 to eliminate the series arrangement. For recloser R237, a 40K or a 25T is the maximum fuse size that provides the proper coordination.

• On Line 7, the existing settings for recloser R259 have been evaluated and approved. Down-line of recloser R259, a 30K or a 20T is the optimum fuse size that provides the proper coordination.

Fuse Size – The location of the existing fuses was based on the distribution model. Fuses larger than an 80K or an 80T do not coordinate fully with the recommended substation relay settings.

Note: On Line 4, on Julia St. between U.S.1 and Sams Ave., there are some taps that appear to be un-fused. A fuse at the beginning of this tap should be installed to improve sectionalizing.

Note: On Line 5, the tap off of Second Ave., serving East Third Ave., appears to be un-fused but should be protected for sectionalizing purposes.

Maximum Fault – All substation and feeder breakers were rated above the calculated maximum faults (See Table 5-4). Based on the calculated results in the engineering model, all line reclosers were also rated above the calculated maximum faults.

Minimum Fault – A fault resistance of 60 ohms for overhead and 40 ohms for underground was assumed to calculate the minimum faults available throughout the UCNSB distribution system, with the exception of the 13 kV Schoolway Substation. In this case a fault resistance of 30 ohms for overhead and 20 ohms for underground was assumed. In some cases, the calculated minimum faults are less than peak load currents on the existing circuits. Ground sensing devices (such as relays and reclosers) are used throughout the industry to detect and respond to these minimum faults, minimizing public risk and equipment damage.

Based on the information provided by UCNSB, ground relays are generally set too high to detect the minimum fault. Therefore, the reduction of ground pick-up is recommended in many cases. The proposed relay settings are given in Exhibit 7 of this report, and the recommended recloser settings are presented in Table 5-6. (See related discussions for “Phase Balancing” and “Switching”)

Continuous Current Rating – All of the substation and feeder breakers were rated above the peak load.

Pickup Setting – In most cases, phase relay settings would prevent transformer or breaker overload. However, some of the backbone circuit conductors were not protected with the existing pickup settings. The proposed settings, in Exhibit 7, were adjusted to protect the existing equipment. Load transfers or conductor upgrades are recommended if the proposed settings can not be implemented due to circuit loading or cold load pickup allowances.

Instantaneous Setting – The UCNSB protection scheme includes instantaneous and units on the feeder relays. In some cases, the relay ground instantaneous settings are set lower than the phase instantaneous settings, and at times, they are responding to faults available at the end of the circuit or reaching beyond down-line devices. This issue is addressed in the recommended settings presented in Exhibit 7 of this report.

Phase Balancing – A more balanced circuit will not only reduce losses, but will allow UCNSB to reduce the ground trip settings to detect the calculated minimum faults and minimize public risk and equipment damage. (See related discussions for “Minimum Fault” and “Switching”)

Switching – Single-phase disconnects can induce significant neutral currents on the system during switching, causing the ground relays to respond.

Ground trip settings were lowered to detect the calculated minimum faults and minimize public risk and equipment damage. (See related discussions for “Minimum Fault” and “Phase Balancing”) To avoid the false response from the ground relay during load transfers, UCNSB can:

• Install three-phase, or gang operated switches, at critical tie points across the system.

• Install relays with alternate settings that can be used during switching operations.

• Bypass the ground relay during switching operations. WARNING! This method does not provide overcurrent protection for the full range of faults.

Section 6 ASSESSMENT OF POWER GENERATION

RESOURCES

6.1 Generation Locations 6.1.1 Field Street Generating Facility The Field Street Generating Facility is situated on approximately 2 acres of property on Field Street in a rural area within the City of New Smyrna Beach. The site is located approximately 600 feet south east of the electric utility’s Field Street Substation and approximately 300 feet from the nearest residential dwelling to the north. Properties to the immediate east, south and west of the site contain dense bush, some of which appear to be natural wetlands. The site is located in an area that is projected to flood by the resulting storm surge from a category 3 hurricane.

Equipment at the site consists mainly of two General Electric Frame 5 combustion turbine generators rated at a nominal output of 24 MW each along with their unit auxiliary equipment, high voltage switchgear, generator step-up transformers and three 30,000 gallon capacity, double walled No. 2 diesel oil storage tanks. The combustion turbine generators were purchased by UCNSB as pre-owned units manufactured in the early 1970’s and were placed in service at the site during the last quarter of 2000. They operate on No. 2 diesel oil only which is delivered to the site storage tanks by road tanker. The output from each generator is synchronized directly to the 23 kV distribution system through separate oil circuit breakers.

We understand that the two generators at Field Street were installed primarily to serve as back-up to the transmission interconnections and to provide peaking power when it is economically advantageous. Based on the plant operating records and information from UCNSB, the units have not been required to operate in a back-up role since installation and it has not been economically advantageous to operate them in preference to purchased power. As a result, the units have seen minimal operation, with average annual service of approximately 19 hours for CTG # 1 and 18 hours for CTG # 2 for the years 2001 through 2005. The starting reliability of the units is reported to be high. The heat rate for the Field Street Generating Facility during the period January through October, 2005 was 16,497 BTU/kWh.

UCNSB does not maintain a formal maintenance log or track plant availability, but informed R.W. Beck that no major maintenance work has been performed on the units since installation and no extended outage events have been experienced. Spare parts kept on hand for the CTGs and auxiliary equipment are minimal and consist of consumable items only. Routine maintenance and plant operation is performed by the UCNSB two-man generating plant staff. There is no long term service arrangement

with the original equipment manufacturer or other such service provider for these units.

During the site visit, the units were not operating, but were said to be in a fully available state. The exterior of the units along with the exhaust stacks and air intake show some rusting to varying degrees, but there appears to be no sign that the integrity of the waterproofing has been compromised. Spill prevention control and countermeasures at the UCNSB sites are being reviewed as a separate assignment. General housekeeping at the site is comparable to other facilities of this type with which we are familiar with no visible significant oil leaks or other visible signs of neglect around the units.

There are many GE Frame 5 units of the same vintage as the UCNSB units in service in the US and around the world and GE along with other after-market parts and service providers have continued to support their operation. It is expected that this high level of support for these units will continue for the foreseeable future. In fact, several fellow FMPA member utilities including Keys Energy, Lake Worth and Fort Pierce operate similar units for peaking and back-up service with no established date for their retirement from service. The units are generally considered to be robust and are not particularly sensitive to the quality of No. 2 fuel oil. However, they are sensitive to the quality of the inlet air and it is advisable to always provide adequate filtration of the compressor inlet air. While GE provides guidelines for the Inspection and Major Maintenance intervals for the units, many users find that using the findings from regularly scheduled borescope inspections is a more accurate predictor of the maintenance needs of the units.

6.1.2 Smith Street and Clinch Street Generating Facilities The Smith Street and Clinch Street Generating Facilities are situated on adjoining properties located on Smith Street, one block south of the Bert Fish Medical Center. A pump and storage facility is situated to the west, and areas immediately to the east and south are residential. The facilities and their immediate surroundings are projected to flood as a result of the storm surge from a category 5 hurricane.

The Smith Street Facility is comprised of a power house building that contains five diesel generators with a reported total capacity of 6,540 kW. These units were manufactured and installed in the power house at various times between 1947 and 1962. The manufacturers include Fairbanks-Morse, GM Cleveland, Superior and Enterprise. One of the units is reported to have a faulty generator and the starting and operating reliability of the others are unknown. Of the five installed units, only three are considered to be potentially operable at this time. The records show that the last time a unit was operated at this facility was during September 2001. The facility is generally unmanned, with staff presence provided during plant operation or fuel deliveries only. Fuel for the units is provided from a 10,000 gallon No.2 fuel oil storage tank.

A very minimal amount of routine equipment maintenance and housekeeping is performed at this site. It does not appear to be in a state of operating readiness. Some plant items are covered by tarpaulin and miscellaneous boxes and containers are stored

on the operating floor. The power plant exhaust pipe work and support structures are severely rusted and aesthetically displeasing. The original metering and electrical protection equipment still exists in the plant and perhaps require replacement or at the very least checking and calibration.

The current availability of spare parts for these units is unknown, since no attempt has been made in recent years to procure spare parts for them. No spares are maintained by UCSNB for these units and it appears that the strategy has been to maintain them in a state of availability with minimal effort and expense until a major failure occurs, at which time the failed unit would be forced into retirement.

Also, it appears that with a current generating staff complement of only two persons in total, UCNSB does not have sufficient qualified staff to operate this facility as well as the Field Street Facility at the same time, since a staff presence must be maintained at both facilities during operation.

The three generating units at the Clinch Street Generating Facility are identical General Motors Electromotive Division (“EMD”), individually housed 2.0 MW diesel generators that were placed in service in 1966. These units are reported by UCNSB to have been very reliable, requiring minimal maintenance over the years. The last major overhaul on one of these units was reportedly performed in 1975. All three units are due for a major overhaul at this time. Currently, one of the units is out of service because of a seized crankshaft. No final decision has been made regarding repair of that unit.

Over the past five years, the Clinch Street units have operated for an average of 250 hours each year. The heat rate for the EMD units during the period January through October 2005 was 11,797 BTU/kWh. Because of the lower heat rate compared with the Field Street units, the Clint Street units are higher in the dispatch merit order and would logically be placed in peaking service in preference to the Field Street CT units. This is reflected in a comparison of the annual operating hours for the two facilities.

6.1.3 Swoope Generating Facility The Swoope Generating Facility is located on the Ponce De Leon Cut about ¼ mile east of the runway at the New Smyrna Beach Municipal Airport. The site is adjacent to the Intracoastal Waterway and is projected to flood during a category 1 hurricane.

The total generating capacity is 5,145 kW which is provided by one 820 kW (Unit 2), one 2,050 kW (Unit 3) and one 2,275 kW (Unit 4) Fairbanks Morse diesel generators. Unit 2 was installed in 1981 and Units 3 and 4 were installed in 1983. All units were new when installed. Fuel for the units is provided from an 18,000 gallon No. 2 fuel oil storage tank at the facility. At the time of the site visit, Unit 2 was not available for service because of a water leak in the radiator. Operating records show that the three generating units operated for an average of 60 hours per year during the past five years with maximum of 124 hours in 2003 and a minimum of 10 hours in 2004. The overall heat rate for the facility for January through October of 2005 was 11,605 BTU/kWh. Except for periods when the generators are operating, there is no staff presence at the facility.

UCNSB stocks only minimal spare parts at the power plant, and staff indicated that in recent years, there has been no need to source major items. Fairbanks Morse continues to be a viable company that provides replacement parts and service for its diesel generators and so obtaining OEM spare parts for these units should not be a problem. Routine maintenance is performed by the two person generating plant staff. General upkeep at the Swoope Facility has been minimal and the spare parts in stock limited to a small number of consumable items. The external piping and radiators show a significant amount of rusting.

A major concern regarding the Swoope Facility is that it is located within the area that is projected to flood as a result of a storm surge inundation and would therefore be evacuated if the area is threatened by a hurricane that is rated at a category 1 or above. Flooding of the engine and associated auxiliary equipment would be catastrophic for the facility.

6.2 Summary Based on their continued use for peak shaving, the availability of spare parts and service and an adequate routine maintenance program, it appears that the Field Street generating units can be maintained for operation at acceptable levels of availability and reliability until the spare parts and service are no longer available or economics dictate that they should be removed from service. At this time, it is anticipated that the parts and service for the GE Frame 5 CT units will continue to be provided by GE and other aftermarket vendors for many years to come in order to service the thousands of such units that in service on a worldwide basis. Over the past 10 years, many of these units have been resold and relocated and some are still being advertised for sale on the pre-owned equipment market. A concern about continued operation at the Field Street site is the fact that it is located in an area that is likely to be flooded by seawater from the resulting storm surge that might accompany a category 3 Hurricane.

The units at Smith Street are already between 47 and 59 years old and it will prove increasingly difficult to source spare parts and service for them, causing unacceptable levels of performance. None of the units have been operated since 2001. Consideration should be given to formally retiring these units from the system.

The EMD MP36 units at Clinch Street are a part of the fleet of portable power units developed by the Electro-Motive Division of General Motors in the 1960’s after the 1965 blackout in the Northeast. The power units utilized engines that were being used in railroad locomotives. A large number of these units were sold for black start auxiliary power in the U.S. and international power plants and thousands remain in service around the world today. EMD is continuing to provide parts and service for this fleet. The reliability of the UCNSB units has been good in the past and this performance should be achieved in the future if an adequate level of routine maintenance is performed. If UCNSB plans to operate these units extensively in the future, then a detailed technical assessment should be performed, with a view of identifying and replacing obsolete auxiliary and control items with modern components that are serviceable. The Clinch Street units are located on property that

ASSESSMENT OF POWER GENERATION RESOURCES

Final UCNSB T&D Studyv2.Doc R. W. Beck 6-5

is projected to be flooded by the storm surge from a Category 5 Hurricane and the base of the units have been elevated by about 3 feet above normal grade level.

The Swoope units are only 23 to 25 years old and Fairbanks Morse continues to provide OEM spare parts and service for them. It is reported that their past performance has been good and therefore from a technical perspective, the facility has the potential to continue operating at an acceptable performance level. However, the facility is located in an area that is likely to be affected by the storm surge from a mere category 1 Hurricane and the equipment is installed essentially at grade level. This should be a major concern for UCNSB.

Average Annual Growth Rate: 1996-2005: 3.3% 2006-2015: 3.4% 2016-2025: 3.3%

Total Personal Income is the primary driving variable in the Preliminary NEL Forecast Model

Note that even the recent “history” is subject to significant revisions and is essentially a projection.

Preliminary Analysis Conclusions Part IIPreliminary Analysis Conclusions Part II

NEL data appears lower than can be explained by Volusia County data over 2001-2005

NSB service territory may have been hit harder by recession and terrorist attacks than the countyNSB appears to be lagging the county in the economic recovery and in average income growth

Projected growth in county households is expected to outpace recent history (3.3% v. 2.8%)However, NEL model results understate potential growth contemplated in CUP

Possible explanations (possibly in combination)Projected county total income is overly conservativeNSB will get a disproportionate share of population and income growthCUP is overly optimistic and reflective of some speculation

Residential Average Use (cont’d)Residential Average Use (cont’d)

Parameters suggest the following:A 10% change in personal income per household will yield about a 7% change in electric consumption (i.e., somewhat inelastic)January billed sales are typically somewhat higher than weather would explain (greater number of billing days due to holiday period?)

On average, model over-forecasts average use during 2001-2005

Income gains in NSB in recent years are likely less than across the countyMany seasonal residents have been less likely to occupy their homes over that period

Final model adjusts for this via an assumed income “drag” term, which then moves higher over the forecast horizon

This case was developed as a basis for comparison of the alternative plans. This case assumes:

Load Level 1:

• At Smyrna Substation, replace (3) single-phase 576 kVA regulators with (3) single-phase regulators of matching impedance, and replace relaying with Microprocessor relays.

• Construct a 115 kV transmission line between Airport and Field Street Substations to complete the loop. Follow the railroad Right of Way for approximately 3.6 miles.

• Bus work at Field Street Substation to move Line 4 to the new transformer.

• Convert various 13 kV taps to 22.9 kV.

• Construct a new circuit to the island using Field Street Substation existing distribution routes.

• Use the spare bay at Airport Substation to build a new feeder.

Load Level 3:

• Install a new 115-22.9 kV, 18/24/30 MVA transformer Load Tap Changers with at Airport Substation.

• Construct a new circuit to the island using Airport Substation existing distribution routes.

Load Level 6:

• Eliminate and remove the Schoolway step-down substation.

• Convert various 13 kV taps to 22.9 kV.

Load Levels 1 -10:

• Various distribution improvements to relieve loading and improve conditions for contingency switching.
