1.0 Introduction and Scope This document is intended to be in compliance with the FRCC and NERC Reliability Standards that are included in the NERC Compliance Enforcement Plan (CEP) and Facility Connection Requirements of FAC-001-0 (Requirements 1, 2 and 3). For facility and equipment ratings, reference the JEA Facility Rating Methodology document dated March 1, 2000. This document is posted on the JEA OASIS web site (http://www.floasis.com/JEA/JEA_home.html). This document applies to all new or modified generation, transmission and end-user facilities that directly connect to the JEA system. It is the policy of JEA to support programs which enhance the quality of life, protect the environment, and provide significant value to the City of Jacksonville and the communities we serve. This document establishes clearly defined technical and safety standards necessary for connection into the JEA system. All connections are to comply with the applicable statutes, ordinances, codes, rules, and regulations of all governmental units, bodies, and agencies. The term “system” means the electrical distribution and or transmission system. The term “facility” means a set of electrical equipment that operates as a single Bulk Electric System Element such as generation, transmission or end use equipment. The term “Applicant” means a Applicant or requestor of a facility connection to the JEA system. The requirements and guidelines found in this document are comparable with those used by JEA when installing new JEA facilities or modifying existing JEA facilities. They are intended to establish a basis for maintaining reliability, power quality, and a safe environment for the general public, maintenance personnel and the equipment. This document is not intended to be a detailed manual but a general overview of procedural and technical requirements. Final design of facility connections to the JEA electrical system will be subject to JEA review and approval on a case-by-case basis. The connection requirements presented in this document are intended to be in compliance with applicable NERC, FRCC, FERC, OATT, NESC, NEC, IEEE and JEA standards. Compliance with these standards is necessary to insure a safe and reliable power system. In the event of an apparent conflict, the apparent conflict should be brought to JEA’s attention immediately.

1.1 Generation Facilities Applicants with generators that are capable of operating in parallel with the JEA system shall comply with all of the requirements of this document. Applicants with generators that are not capable of operating in parallel with the JEA system pose less risk to the JEA system and may not be required to comply with all of the requirements of this document. Instead, they shall comply with Section 2.16 of JEA’s Rules and Regulations for Electric Service (available at jea.com). 1.2 Transmission Facilities Applicants with transmission facilities capable of operating in parallel with the JEA system shall comply with all of the requirements of this document. 1.3 End User Facilities Applicants with end user facilities directly connected to the JEA system (i.e. primary metered Applicants) shall comply with all of the requirements of this document. 2.0 Connection Requirements This section is intended to provide JEA’s plan for achieving the required system performance as described above throughout the planning horizon. The process for gaining interconnection to JEA’s System is as follows:

1. Application for Connection 2. Fees 3. Feasibility Study 4. Impact Study 5. Facility Study 6. Connection and Operations Agreement

2.1 Connection Required System Performance The JEA Facility Connection Requirements serves as a general outline for any Applicant facility that connects to the JEA system. All new or modified facilities that can affect the reliability of the JEA and neighboring systems must comply with this document. During project negotiations a determination will be made as to the probable impact to JEA’s system. The Applicant assumes the cost of all design, construction, inspection, analysis, maintenance, operations, monitoring, and all associated facilities needed to satisfy the technical and safety requirements identified for connection into the JEA system. Some exceptions to these requirements may be made by JEA based on the preliminary assessment of the connection’s potential system impacts on a-case-by-case basis.

January 14th, 2006 4/22


2.1.1 Procedure for Connection Joint Studies With the addition or change of any system connection, the system configuration and power flow pattern in the utility changes. These changes must be studied and evaluated to determine probable impacts to the system. Three studies will be used to perform the evaluation for all proposed changes to the JEA system. The Applicant will be responsible for paying JEA for those studies. The specific voltages, MW and MVA capacity, demand and other parameters of the Applicant’s Facility will be determined as a result of the Studies and specified in the Connection and Operations Agreement.

Application for JEA Facility Connection: All Applicants desiring to connect new facilities or to modify existing sites shall apply for a Facility Connection, using the attached form. An Applicant shall submit a separate Application for each Connection and may submit multiple Applications for a single Facility. The Applicant will not be allowed to exceed the specified capacity unless the Applicant makes a second Application for the increase in capacity of the Facility.

Fees: Applicants wishing JEA to consider adding or modifying a connection to JEA’s transmission system are asking for a special service and will be charged for the cost of that special service. Each study is a special service. The intent of the special service charge is to cover all of JEA’s costs for evaluating the Facility Connection request. The special service charge can be impacted by changes in scope; possibly requiring additional studies, changing the type of connection, size and the location of the facility. The special service charge for each study will be reconciled at the completion of each study. The Applicant must pay all monies due to JEA before it is allowed to obtain any study data/results or before additional studies are made.

Feasibility Study: A Feasibility study is a quick assessment of the proposed project based on previous studies, general knowledge of system performance and dedicated studies of the system. The purpose of this study is to provide a quick initial assessment of the project impacts and if changes to the system will be required. The documentation of this study may be informal or formal.

January 14th, 2006 5/22


Impact Study: The Impact Study occurs after the Feasibility Study is completed. The Impact study is a detailed engineering evaluation of the proposed project effects on the JEA system and neighboring utilities. The study identifies any system changes that might be required to accommodate the project and keep the JEA system compliant with industry standards. This study may include Load Flow, Short Circuit, Stability, and other types of analysis as required. The Impact Study may also include analysis by FRCC and neighboring utilities on the impact of the project to the overall system and their specific parts. Facility Study: The Facility study occurs after the Impact study is completed and develops the actual physical implementation plans for the facility connection. The study will include as a minimum; power quality, protection coordination, surge protection, insulations requirements and insulation coordination. Depending on the Applicant there may not be a single document labeled “facility study”, but instead the collection of design, estimate and supplemental studies may be considered the facility study.

Connection and Operations Agreement: At the completion of the Facilities Study, a Connection and Operations Agreement will be negotiated between the Applicant and JEA. This agreement will provide a yearly review to ensure full compliance and possible changes driven by changing circumstances and JEA needs. Construction of Connection facilities or system upgrade facilities will not begin until there is agreement among the parties and there is an executed Connection and Operations Agreement. The Applicant will not be allowed to connect its Facility until Connection facilities and system upgrades are completed, although it may be possible to allow for back-feed and test power. The Connection and Operations Agreement address responsibilities for: - Initial Cost (Design, construction, commissioning, operations, etc…) - Allocation of ownership of facilities - Operations and maintenance - Schedule - Liabilities

2.1.2 Procedure for Notification of FRCC and Others of Proposed Project

Project Notification for Joint Study: If the proposed project meets certain criteria established by the FRCC and JEA, JEA will contact the FRCC to set up a joint study. Contacting FRCC would typically be done during the final stages of the Facility Study. A review of the project will then be initiated per FRCC Procedures. If the project does not meet the level of FRCC Review, JEA may still contact entities that may be impacted for their review of the project. Project Notification for Modeling: Once the project moves into the facility study stage (occasionally earlier) it will be added to the FRCC databank and the FRCC Project schedule by JEA.

2.1.3 Voltage Level, MW & MVAR Capacity or Demand at Point of Connection An essential part of operating a reliable transmission system is the coordination of real and reactive power sources with real and reactive loads. Every effort is made to maintain an adequate transmission voltage profile both for normal and contingency conditions. Real and reactive loads/sources distributed throughout electric systems can cause large voltage drops associated with transmission of reactive and real power. JEA voltage and power control strategies are intended to minimize the risk of exceeding equipment voltage limitations and the transmission grid’s voltage stability limitations. Nominal transmission voltages for JEA are 500 kV, 230 kV, 138 kV and 69kV. These systems are typically operated between +/- 5% of nominal and +5%/-10% of nominal during emergency conditions. All equipment connected by the applicant to the JEA system shall be designed for continuous operation at +/- 10% voltage range of nominal. The Applicant and JEA will discuss the available voltages, MW & MVAR capacity or demand at the point of connection during the feasibility and impact studies. This information will be used to perform the studies and will be forwarded to the FRCC at the appropriate time per section 2.2 above. 2.1.4 Breaker Duty and Surge Protection The system studies will determine the minimum requirements for breaker interrupting capability. All equipment must be designed to withstand temporary overvoltages (swells and surges) caused by ground faults. The level of overvoltage and the duration will be determined as part of the Facilities Study and specified in the Connection and Operations Agreement.

January 14th, 2006 7/22


2.1.5 System Protection and Coordination The Applicant’s equipment that affects the performance of JEA’s system shall be utility grade and meet or exceed JEA’s requirement for similar equipment as found in the JEA Transmission and Substation Construction Standards. All equipment insulators and protection equipment must coordinate with the JEA system. JEA shall review and approve the protection system design and equipment of the Facility. Compatible relaying equipment must be used on each side of the point of ownership within a given zone of protection. The design must provide coordination for speed and sensitivity in order to maintain power system security, reliability and to prevent breaker misoperations. JEA, the Applicant and neighboring utilities shall work together to perform protection system coordination studies and set protection system relays accordingly in accordance with NERC protection and control Standard PRC-001. Protection systems shall be designed to remove ground faults promptly, such that no equipment exceeds its capabilities of withstanding swells and faults. The allowable magnitude of voltage swell and the allowable duration of fault currents shall be determined as part of the Facilities Study and specified in the Connection and Operations Agreement. All major pieces of equipment shall be protected in their own protection zone with independent and redundant protection systems. The primary protective relaying shall operate with no intentional time delay for 100% of the specified zone of coverage. On transmission lines, this is accomplished through the use of a communication channel. JEA may require a second high-speed protection system, depending on critical clearing times. Backup protective systems should provide additional coverage for breaker and relay failure outside the primary zone. Specific breaker failure protection schemes and relay failure backup schemes must always be applied at the system level. At least one power source for tripping and control must be provided at substations by a DC storage battery. The battery is to be sized with enough capacity to operate all tripping devices after eight hours without a charger. An undervoltage alarm must be provided for remote monitoring by the Applicant who shall take immediate action to restore power to the protective equipment. JEA may require redundant battery systems and redundant breaker trip coils, depending on critical clearing times and the importance of the Facility and Connection to the Bulk Electric System. Facility protection devices shall include a circuit breaker to be located on the Facility and on the high side of each point of interconnection. The Applicant’s Facility operator shall be solely responsible to disconnect the Facility from the System if System conditions are such that continued connection would damage the Facility.

January 14th, 2006 8/22


Circuit Breaker The following standards are referenced in the breaker specifications:

• ANSI C37.04, IEEE Standard Rating Structure • ANSI C37.06, Standard for Switchgear- AC High-Voltage Circuit Breakers

Rated on a Symmetrical Current Basis- Preferred Ratings and Related Required Capabilities.

• ANSI C37.09, IEEE Standard Test Procedure for AC High-Voltage Circuit Breakers Rated on a Symmetrical Current Basis.

• IEEE C37.010b, Standard for Emergency Load Current-Carrying Capability

• IEEE C37.010e, (Supplement to IEEE C37.010) • ANSI/IEEE Standard C37.90 (protective relays)

2.1.6 Metering and Telecommunications Communications for protection must function at the full performance level before, during and after any power system fault condition. Metering JEA shall purchase and install required metering equipment at the point of Connection prior to any operation of the Facility and shall own, operate, test and maintain all such equipment. JEA shall inspect and test all of its metering equipment upon installation and thereafter at intervals not to exceed two (2) years. The Applicant may, at its sole option and expense, install check meters on its premises and on its side of the Connection to verify JEA’s meters. The check meters shall be subject to inspection by JEA at all reasonable times. The metering equipment required will be determined by the rate, size and type of facility. Each connection will need to be evaluated separately for metering requirements because of the many possible contractual agreements and interconnection configurations. Specific metering and reporting systems will be designed and developed to meet those requirements. As a minimum, the following quantities are expected to be provided by JEA for each connection point:

Received Delivered MW-hours MW-hours MVAR-hours MVAR-hours Three Phase Voltage Three Phase Voltage Three Phase Current Three Phase Current +/- MW +/- MW +/- MVAR +/- MVAR

Three element meters will be use for revenue metering, and will have an accuracy class of 0.3% or better. Transducers will be accurate to +/- 0.2% of full

January 14th, 2006 9/22


scale. Metering accuracy CTs and PTs will be installed as close to the delivery point as practical. CT ratios will be selected just above the expected full load. Instrument transformers will have an accuracy class of 0.3%. Backup current transformers (CT’s) and potential transformers (PT’s) are not required. Metering CT’s and PT’s will not be used to feed non-metering equipment such as protective relays. Auxiliary CT’s are not to be used in metering circuits. When more than one point is to be monitored, individual metering will be used. The impedance of the CT and PT cable leads will be kept low and not impose burdens above that of the instrument transformer rating. Revenue meters are to remain sealed during operation and following maintenance or calibration testing. If the JEA metering equipment fails to register or reads more than 2% different from standard test meters, JEA will adjust all readings taken since the last verified test by using the Applicant’s check meter, if installed. If no check meter was installed, JEA will estimate the adjustment using industry accepted engineering methods. JEA will provide metered quantities in a mutually agreed upon format to the Applicant upon request. All metered data will be sent electronically to locations designated by the JEA and the Applicant. This data will be used as the official measurement of the amount of energy delivered to or withdrawn from the System by the Facility. Telecommunications All of the metering data shall be communicated instantaneously and continuously to JEA via the data circuits. Prior to initial connection to the System, the Applicant shall establish voice and data communications with JEA. Communication systems shall be in accordance with NERC Standards COM-001 and COM-002. Both communications shall be installed and be fully operational prior to the initial connection of the Facility to the System. The voice communications shall be sufficiently redundant so that a failure of a single phone cable/switch/etc… will not render all inoperable (standard dial up phone service, fax or dedicated phone connection). The data communications shall have two main functions; a remote terminal unit (“RTU”) and communication to disturbance monitoring equipment (Section 2.1.14 below). The RTU shall be compatible with and controlled by JEA’s supervisory and data acquisition system (“SCADA”). The RTU shall be connected to JEA’s SCADA by a dedicated method with redundancy. The data required from the RTU and disturbance monitoring equipment will be negotiated and specified in the Connection and Operations Agreement.

January 14th, 2006 10/22


2.1.7 Grounding and Safety The Facility shall conform in all ways to all applicable government and industry standards for grounding and safety; including but not limited to the National Electrical Safety Code, OSHA, National Electrical Code, IEEE Guides and Standards, ANSI Standards, NERC Standards, and to JEA’s safety and installation standards. Strict adherence to established switching, tagging and grounding procedures will be required at all times. Under no circumstances shall the Facility attempt to energize a “dead” transmission line unless agreed to in advance by JEA, with the exception of a JEA approved transmission connection automatic reclosing scheme.

2.1.8 Insulation and Insulation Coordination The insulation levels and surge protection required for the Applicant’s facility shall coordinate with those of JEA and meet JEA standards. Additional insulation beyond normal industry requirements are required due to isokeraunic levels (thunderstorms) of Florida and the coastal environment (potential for salt build-up on insulators). Depending on the location of the Facility and the Connection in proximity to the shoreline, it may be necessary to wash insulators periodically to eliminate salt accumulation on the insulators. The necessity and frequency of this maintenance practice will be negotiated in the Connection and Operations Agreement. Also, the Basic Impulse Insulation level (BIL) of the equipment and surge protection specifications will be determined as part of the studies. 2.1.9 Voltage, Reactive Power and Power Factor Control Power systems are highly nonlinear and the dynamic characteristic of a power system varies as the system generation, transmission and loading change. Operators of transmission systems follow voltage control strategies to minimize the risk of exceeding equipment voltage limitations and the transmission grid’s voltage stability limitations. Neighboring utilities, JEA and the Applicant’s facility operators are expected to work together to constantly monitor and control voltage, reactive power and power factor. Closely matching energy flow will make the system more stable under normal conditions and less likely to become unstable during system disturbances. The Facility Study will identify voltage issues and reactive power issues associated with new or modified connections in accordance with NERC Standard VAR-001. The burden of matching the flow is shared by the generation, transmission and end users. Each must do their part.

January 14th, 2006 11/22


Generators and Step-Up Transformers Generators must contribute reactive power while regulating voltage. All generators must be capable of continuous operation at voltages of +/- 5% of nominal at the generator terminal. The generator shall be capable of continuous operation at 0.9 power factor leading and 0.95 power factor lagging at peak conditions as measured at the JEA metering equipment. Generators operating in parallel with the transmission system must be synchronous generators and operate with a Step-Up transformer sized to the capacity of the generator. The step-up transformer shall have an automatic voltage regulator (“AVR”) operated in automatic while following the established voltage schedule for the voltage control strategy to be effective. This can only be accomplished by using the automatic voltage control mode. Using the Power Factor (PF) or constant MVAR control is not a true method to control voltage even though they may have some effect on voltage. However, if JEA specifically directs the Generator Operator to operate the AVR in a mode other than constant voltage mode, then that directed mode of AVR operation is allowed The no-load tap settings for the Facility will be designed in accordance with NERC Standards VAR-001 and VAR-002. The AVR must have tap changers capable of changing the ratio of the transformer by at least +/- 5% with a maximum tap step size of 2.5%. A typical voltage schedule for generators is:

Switchyard 10am-10pm 10pm-10am Nominal Voltage Scheduled Voltage Scheduled Voltage

69kV 72.0 kV 69 kV 138 kV 140.0 kV 136 kV 230 kV 240.0 kV 235 kV 500 kV 522.0 kV 517 kV

The JEA System Operator will advise generating plant operators of the current voltage schedule. This voltage schedule may change on an hourly basis depending on conditions in the power system. The operator of the generator must contact the JEA System Operator when the generator can not maintain the voltage at the point of interconnection as prescribed by the JEA System Operator for more than 30 minutes. The operator of the generator shall state the reason for deviating from the voltage schedule and provide the JEA System Operator with the generator’s reactive limitations that exist at that time. Owners of generating equipment are responsible for maintaining records that provide a summary of the number of hours per month each generator was not

January 14th, 2006 12/22


following the voltage schedule along with the date, duration, and reason for each period of occurrence. These records must be available for the preceding 12 months and must be provided to JEA within five business days of a request. Transmission Because of nature of transmission systems and their energy flow, Transmission Applicants will be responsible for both Generation and End-user requirements. End-Users Power Factor of the Facility at the Connection must be maintained between

0.95 lagging and 1.00 (Unity) - Off Peak Hours 0.97 lagging and 0.98 leading – Peak Hours It is the End-Users responsibility to regulate voltage on its facilities. It is recommended that the Applicant install step-down transformers with No-Load Tap Changers capable of regulating voltage +/- 10% of nominal in 33 steps, and a no-load tap changer capable of +/- 5% of nominal in 5 steps. 2.1.10 Power Quality The power quality impact of a facility may be assessed during the facility study and post installation. The Facility shall not degrade the quality of the System’s voltage or current and shall operate within limits as established by the following standards and guidelines:

ANSI C84.1 – Voltage Variations IEEE Standard 519 - Harmonics IEC 61000-2-2, IEEE - 1453 Voltage Flicker ANSI / NEMA MG1, IEEE 112, ANSI C84.1

Voltage Balance, Negative Sequence Voltage and Current Switching Transients

If JEA determines that Power Quality issues exist, it is possible that additional analysis may be necessary (e.g., harmonics studies, transient studies) at the Facilities to determine whether Power Quality criteria are met. If not, additional equipment may need to be installed as part of the connection (e.g., harmonic filters, additional surge protection, higher insulation levels, etc.). The cost to remedy any unforeseen power quality problems generated by the Applicant will be the responsibility of the Applicant. 2.1.11 Equipment Ratings The Applicant’s equipment that affects the performance of JEA’s system will need to meet or exceed JEA’s requirement for similar equipment found in the JEA Substation and Transmission Construction Standards. Consideration should

January 14th, 2006 13/22


be given for forecasted system growth in the selection of equipment. All new equipment associated with the Facility and the Connection shall be rated a minimum of 20% above the maximum loading determined by the JEA studies for a 10 year planning horizon (except the Step-Up transformer for a generator, which needs to be sized to the capacity of the generator). The Applicant is responsible for developing ratings methodologies and ratings for equipment owned by the Applicant (e.g., NERC Standards FAC-008 and FAC-009). The Applicant will be required to test MW and MVAR capabilities in accordance with NERC Standards MOD-024. AC high voltage circuit breakers are specified by operating voltage, continuous current, interrupting current and operating time. These ratings shall be indicated on the individual circuit breaker manufacturer nameplates. If the Applicant desires to be able to exceed the rating stated in the previously agreed Connection and Operations Agreement, a new Application is required before the change(s) are made (Exceptions: the Applicant may exceed the specified capacity or demand if it is during an emergency condition as determined by and agree to by JEA). 2.1.12 Synchronizing of Facilities All facilities with will be required to have at least one functional synchronizing check relay (IEEE Device 25) that supervises the connection and prevents asynchronous closing. The Applicant shall be responsible for protection, coordination and synchronization of the Applicant's equipment with JEA's electrical system, and assumes all responsibility for damage that may occur from improper coordination or synchronization of the equipment with JEA's system. All synchronization of the Facility to the System shall be with the circuit breaker on the high side of the Facility or on the Applicant’s side of the Connection. Under no circumstances shall JEA’s circuit breakers be used for this task. Additional synchronizing requirements will be negotiated in the Connection and Operations Agreement. 2.1.13 Maintenance Coordination The Applicant is solely responsible for all maintenance of the Facility and the Connection equipment owned by the Applicant. The removal of the Facility from service for routine maintenance shall be scheduled with JEA a minimum of six (6) months prior to beginning, and JEA shall have the right to modify said schedule if JEA maintenance planning projects potential issues that may compromise the reliability of the Bulk Electric System. No removal for routine maintenance will be allowed if the Facility’s capacity is required to meet projected demands during the projected outage period.

January 14th, 2006 14/22


For equipment that is designated as having an impact on JEA transmission performance the Applicant is required to perform maintenance as recommended by JEA, manufacturer and industry standards. JEA reserves the right to inspect equipment and maintenance records to insure the equipment is being properly maintained. Applicants connecting to the System shall investigate and keep a log of all protective relay actions and misoperations as required by the FRCC in compliance with NERC Standard PRC-004. If NERC Standard PRC-005 applies to the Applicant, the Applicant connecting to the System must have a maintenance and testing program for their protection systems, and have evidence that the maintenance and testing program is being carried out according to plan. Documentation of the protection maintenance and testing program shall be supplied to JEA, the FRCC and NERC on request in accordance with NERC Standard PRC-005. The Applicant shall perform both calibration and functional trip tests of its protection equipment at intervals described in the documented maintenance and testing program, and following any apparent malfunction of the protection equipment. JEA shall review and approve any protection system design or set point changes of the Facility and the Connection. Mechanical and electrical logic and interlocking mechanisms are required between interconnected facilities to ensure safe and reliable operation. These include, but are not limited to, breaker and switch auxiliary contacts, undervoltage and synch-check relays, and physical locking devices. A transfer trip is required for many installations. It is used for backup protection and islanding schemes. For new installations, fiber optics is the preferred means of communication (Power line carrier schemes may not be used). 2.1.14 Abnormal Frequency and Voltage The Facility shall be designed to readily accommodate the permanent installation of disturbance monitoring equipment (The JEA Standard is ION – Power Measurement). The Connection and Operations Agreement will have within it provisions for JEA to direct the Applicant to install maintain and test disturbance monitoring equipment in accordance with NERC Standards IRO-001, TOP-001, PRC-018 and PRC-002 at the time of construction or at a later date. The system in Florida generally experiences voltages between 90% and 106% of nominal, and frequencies between 59.9 and 60.1 Hz. It is possible during a rare system event that voltages and/or frequency to exceed these limits. The generator and its protection systems shall be designed to meet the performance requirements of FRCC Standard PRC-024-FRCC-01 to ensure that the Facility can “ride through” frequency deviations of predetermined magnitudes. The

January 14th, 2006 15/22


Applicant is responsible for installing any protective devices necessary to protect their system from these rare excursions. Generation Generating facilities must be designed to remain on line for normal clearing system faults within the close proximity to the plant switchyard. Voltage may approach zero at the switchyard bus for six cycles for some types of faults. Control systems, contactors, motors and auxiliary loads that might otherwise cause a generator trip if lost must not drop out under these conditions. Critical contactors must be provided with ride-through capability where required. Additionally, generator protection systems such as the Load Drop Anticipator, Early Valve Actuator or Power Load Unbalance should not be designed to trip a generator for normal clearing external faults or stable swings. Transmission In the course of studies described above, and in the course of annual planning studies, there may come a time when it is determined that the Applicant’s Transmission Facility may require specialized protection systems, such as out-of-step relaying, synch check relaying, etc., to maintain the reliability of the System. If such specialized protection is deemed to be necessary, the Applicant will be required to install the relaying. Installation, maintenance, testing and operations of the specialized protection system equipment will be addressed in the Connection and Operations Agreement, including provisions to install such equipment at a later date. End Use Under-Frequency Load Shedding (UFLS) and/or Under-Voltage Load Shedding (UVLS) equipment may need to be installed at the Facility to meet JEA’s obligations for NERC Standards PRC-007 and/or PRC-010. Installation, maintenance, testing and operations of the UFLS or UVLS equipment will be addressed in the Connection and Operations Agreement, including provisions to install such equipment at a later date. 2.1.15 Inspection Requirements

Inspection requirements will vary depending on the type and size of the facility. These requirements will be established during the facility study and adjusted as needed during implementation. In general JEA reserves the right to inspect as needed any user facilities that can impact the JEA systems. These inspections may be routine, random or based on a system event or complaint. Inspection rights will be negotiated as part of the Connection and Operations Agreement.

January 14th, 2006 16/22


2.1.16 Communication and Procedures during Normal and Emergency Operating Conditions During normal and emergency operating conditions the JEA operations groups and the FRCC State Reliability Coordinator is charged with maintaining a safe and reliable system in Florida. In accordance with NERC Standards, all Applicants are expected to immediately follow directives issued by the JEA operations groups, the State Reliability Coordinator or their designee when those directives are considered critical to maintaining the system (refer to Interconnection Reliability Operations IRO-001 and Transmission Operations TOP-001). Specific details on communication and procedures will vary depending on the type, size and location of the facility and will be established on a case by case basis. Specific details regarding these functions will be included in the Connection and Operations Agreement. 2.2 Interconnection at a Substation JEA will require all connections to the portion of the System owned by JEA be at a substation. If no substation exists at the point of interconnection, a new substation shall be constructed. This substation shall be designed such that there are at least two (2) termination bays to allow the existing line to be looped through the station and the additional bays required for the new facilities. The new substation design shall be either a “breaker and a half” or a “ring bus” design. JEA will designate which type, if either, is required during the Application approval process. The applicant shall provide, or obtain from others, the property required for the new substation. The applicant is responsible for the cost of providing or obtaining this property. 2.3 Easements and Rights-of-Way If a JEA line extension is required to accommodate an Applicant’s connection, the applicant shall provide, or obtain from others, suitable easements or rights-of-way. The applicant is responsible for the cost of providing or obtaining these easements or rights of way. 2.4 Site Access There are situations where some equipment that is owned by JEA is located within the Customer’s facility. This is often required for data acquisition or metering. In these cases, installed equipment owned by JEA will be clearly identified as such on the appropriate station drawings, on the reference documents and at the site. Continuous unrestricted site access is to be provided to JEA employees where JEA equipment is located within the Customer’s facility.

January 14th, 2006 17/22


2.5 Safety Safety is of utmost importance. Strict adherence to established switching, tagging and grounding procedures is required at all times for the safety of personnel. Any work carried out within a facility shall be performed in accordance with all applicable laws, rules, and regulations and in compliance with Occupational Safety and Health Administration (OSHA), National Electric Safety Code (NESC) and good utility practice. Automatic and manual disconnect devices with approved lockout devices are to be provided as a means ofremoving all power sources to any particular element of the power system. Only trained operators are to perform switching functions within a facility under the direction of the responsible dispatcher or designated person as outlined in the National Electric Safety Code. 2.6 Reliability and System Security JEA designs and operates its transmission system to meet FRCC and NERC Planning and Operating Standards. The planned transmission system with its expected loads and transfers must be stable and within applicable ratings for all category A, B, and C contingency scenarios. The effect of category D contingencies on system stability is evaluated when changes are planned in the transmission system. The design of new transmission connections should take into account and minimize, to the extent practical, the adverse consequences of category D contingencies. Higher probability category D contingencies, when they occur in combination with forecasted demand levels and firm interchange transactions, must not result in uncontrolled, cascading interruptions. While controlled interruption of load and/or opening of transmission circuits may be needed, the system shall be within its emergency limits and capable of rapid restoration after operation of automatic controls. System and generator stability is to be maintained for normal clearing of all faults. A total clearing time for all faults shall follow JEA approved standards and practices for the specific interconnections. The power system must be stable for single line to ground faults with the failure of a protection system component to operate. This includes clearing of a system fault with the simultaneous failure of a current transformer, protective relay, breaker, or communication channel. Three phase faults with the failure of a protection system component to operate are to be considered in all design alternatives with adverse consequences to system stability minimized.

JEA transmission circuits are protected with primary system relays that provide no intentional time delay when clearing faults for 100% of a line. A second high-speed relay system with communications and no intentional time delay is required if a failure of the primary system can result in instability when a fault is cleared by time delay backup protection. This can be the case for an end of line fault on a short line combined with a failed relay. Likewise, two independent high-speed protection systems may be required for bus protection if backup clearing results in instability. 2.7 Protective Relaying JEA standard transmission level protective relays and fault clearing systems are to be provided on the interconnected power system. All protective relays should meet or exceed ANSI/IEEE Standard C37.90. Adjoining power systems may share a common zone of protection between two parties. Compatible relaying equipment must be used on each side of the point of ownership within a given zone of protection. The design must provide coordination for speed and sensitivity in order to maintain power system security and reliability. All bulk transmission power systems are to have primary protective relaying that operates with no intentional time delay for 100% of the specified zone of coverage. On transmission circuits, this is accomplished through the use of a fiber optic communication channel. A second high-speed protection system may be required on a line or bus. Backup protective systems should provide additional coverage for breaker and relay failure outside the primary zone. Specific breaker failure protection schemes must always be applied at the bulk transmission level. Specific relay failure backup must also be provided. Backup systems should operate for failures on either side of an interconnection point. Time and sensitivity coordination must be maintained to prevent misoperations. A power source for tripping and control must be provided at substations by two 125 VDC storage battery banks. The battery banks are to be sized with enough capacity to operate all tripping devices after eight hours without a charger. An under voltage alarm must be provided for remote monitoring by the facilities owners who shall take immediate action to restore power to the protective equipment. Mechanical, electrical and electronic logic and interlocking mechanisms are required between interconnected facilities to ensure safe and reliable operation. These include, but are not limited to, breaker and switch auxiliary contacts, under voltage and synch-check relays, and physical locking devices.

A transfer trip is required for all installations. It is used for backup protection and islanding schemes. Fiber optics is the required means of communication for primary relaying schemes. Entities connecting to the JEA transmission system shall investigate and keep a log of all protective relay actions and misoperations as required by the FRCC in compliance with NERC Planning Standards. The most current requirements for analysis and reporting of protection misoperations are available from FRCC staff. Entities connecting to the JEA transmission system must have a maintenance program for their protection systems. Documentation of the protection maintenance program shall be supplied to JEA, the FRCC, and NERC on request. Test reports as outlined in the maintenance program are to be made available for review by JEA and the FRCC. At intervals described in the documented maintenance program and following any apparent malfunction of the protection equipment, the entity shall perform both calibration and functional trip tests of its protection equipment. 2.8 Reclosing It is JEA’s practice to automatically and manually test its transmission lines following breaker operations for system faults. This is required to minimize customer outage time and maintain system stability. On 230 kV lines and below, automatic reclosing occurs at 0.25 seconds after fault clearing. A second automatic reclose may be initiated at some locations within a designated period after fault clearing. Manual reclosing and sectionalizing may also occur. Interconnected facilities must not interfere with JEA’s ability to quickly restore transmission lines following temporary or permanent system faults. Automatic reclosing on lines originating at JEA generation sites is usually accomplished by hot line synch-check permissive. The remote end of the line from an JEA generator should be equipped with a dead line permissive for automatic reclosing. Any party wishing to interconnect with JEA must consider the implications of automatic reclosing in their design.
