Section 2: Transmission Services
2.1: Transmission Service 2013 Overview
Studies are conducted as a result of customer-submitted long-term firm transmission service requests to determine if the SPP transmission system can accommodate transmission service above what is currently in use. In October of 2013, SPP implemented a new process for evaluating transmission service requests, designed to more expedite the evaluation of requests in the queue currently (The “Backlog Clearing Process”). The Backlog Clearing Process1 is intended to clear the queue of pending requests in anticipation of a new process that will permanently replace the existing process and that will be more efficient and streamlined. This successor process to the Backlog Clearing Process is still in development in the SPP stakeholder process.
The Transmission Provider will combine all long-term point-to-point and long-term designated network resource requests received during a specified period of time into a single Aggregate Transmission Service Study. Using this Aggregate Transmission Service Study process, the Transmission Provider will combine all requests received during an open season to develop a more efficient expansion of the transmission system that provides the necessary ATC to accommodate all such requests at the minimum total cost.
During 2013, SPP Staff posted 23 Aggregate Facilities Studies, as compared to 21 in 2012, to meet 60-day study completion deadlines and FERC Order 890 requirements. Order 890 requires Transmission Providers to file notice with FERC if more than 20% of the Facilities Studies in any two (2) consecutive calendar quarters are not completed in the 60-day study window. In 2013, SPP was not required to file with FERC, as there were no two (2) consecutive quarters in which more than 20% of the studies were late. This was due in large part to the timely submission of documentation by Transmission Owners.
The tables below summarize the Aggregate Studies that were closed and produced Service Agreements during 2013. The tables show the number of requests and requested capacity (MW) for the initial study (AFS1) and the final number of requests and requested capacity (MW) for the last study iteration (AFS11, AFS10).

2.2: Tariff Attachments AQ and AR
Attachment AQ
SPP Tariff Attachments AQ defines a process through which delivery point additions, modifications, or abandonments can be studied without having to go through the Aggregate Study process. Delivery points submitted through the process are examined in an initial assessment to determine if a project is likely to have a significant effect on the transmission system. If necessary, a full study is then performed on the requested delivery points to determine any necessary upgrades. There were six (6) NTC’s issued in 2013 as a result of the AQ process. A flowchart of the AQ Study process in contained in Appendix F.
The number of requests and required studies are summarized in Table 2.4 below.

Attachment AR
Attachment AR defines a screening process used to evaluate potential Long-Term Service Request (LTSR) options or proposed Delivery Point Transfers (DPT). The LTSR option provides customers with a tool to assess possible availability of transmission service. The DPT screening study option enables customers to implement a DPT via issuance of a service agreement more expediently pending the results of the screening. Both of these screening tools allow for a more streamlined Aggregate Study process by reducing the number of requests in the studies. A flowchart of the AR Study process in contained in Appendix F.
During 2013, four (4) DPT studies were posted, two (2) of which were granted service. Four (4) LTSR studies were requested and posted. Three (3) LTSR studies were requested and posted.

Section 3: Generation Interconnection
3.1: Generation Interconnection 2013 Overview
A Generation Interconnection (GI) study is conducted pursuant to Attachment V of the SPP Tariff whenever a request is made to connect new generation to the SPP transmission system. GI studies are conducted by SPP in collaboration with affected Transmission Owners to determine the required modifications to the transmission system, including cost and scheduled completion date required to provide the service.
As of October 30, 2013, SPP received 35 SPP and 7 affected system GI requests, similar to the 35 SPP and 7 affected system study requests received through the same period in 2012. As of that date, there were 29 active queue requests for 3,973.4 MW under study and 6 requests were removed from the queue either from being withdrawn by the requesting Transmission Owner or from the execution of a Generation Interconnection Agreement (GIA). The 7 affected system study requests were made by neighboring systems requesting SPP’s evaluation of the impact of the requests on SPP’s transmission system.
The approval of Priority Projects has facilitated the increase of Generation Interconnection requests. About 6,500 MW of additional Generation Interconnection Agreements were approved based on the existence of Priority Projects and Balanced Portfolio.
The graph below shows the total estimated cost of Generation Interconnection projects included in the 2014 STEP as compared to previous STEP Reports. Fluctuations in the annual STEP estimates may be influenced by the number of new projects identified in completed Generation Interconnection Studies that have either been issued NTCs or are approved and are awaiting the issuance of an NTC, the completion of Generation Interconnection related projects, and the increase and decrease of Transmission Owner submitted projects cost estimates within the applicable STEP timeframe.

3.2: Generator Interconnection Improvements
SPP-proposed changes to the DISIS process were approved by the MOPC and BOD in April 2013. Tariff language was approved in October 2013. The improved process establishes a path that will allow Interconnection Customers who are ready to construct their projects the ability to do so without the current uncertainties related to having a later queue position. The new process makes changes to the “first ready” approach that was established in 2009. SPP will allow more time for customers to remedy deficiencies in their applications before studies begin. Interconnection Customers should be able to move through the process shown below as long as they meet the financial and construction milestones required and will be able to start construction of their projects within 11 months of the start of the study.
The amount of time to a final study result will be reduced from the current average time of 24 months to approximately 11 months. Interconnection Customers that move forward in the process will have less exposure to restudies since less viable projects will not be moving forward into Interconnection Agreements. Customers will save money on restudy costs.
The improved process will increase the burden on Interconnection Customers that do not have a viable project and will encourage those projects not to enter the queue until such time that their projects become viable. It is thought that the administrative and study work on SPP Staff will be neutral. While the DISIS studies will be more complex, there will only be one DISIS study in progress at any one time. Multiple restudies of multiple clusters will not be necessary.
The improved process is expected to provide value by providing cost and time certainty to Interconnection Requests that are ready to build their generating facilities.
The new process is shown in Figure 3.2. Information on the Generation Interconnection Improvements Process can be found on SPP’s website posted under background materials for the April 16-17, 2013 MOPC meeting (SPP.org>Org Groups>MOPC>MOPC Documents).

Section 4: Integrated Transmission Planning
The Integrated Transmission Planning (ITP) process is Southwest Power Pool’s iterative three-year study process that includes 20-Year, 10-Year, and Near Term Assessments.
The 20-Year Assessment (ITP20), performed once every three (3) years, identifies transmission projects, generally above 300 kV, needed to develop a grid flexible enough to provide benefits to the region across multiple scenarios.
The 10-Year Assessment (ITP10), performed once every three (3) years, focuses on facilities 100 kV and above to meet system needs over a 10-year horizon.
The Near Term Assessment (ITPNT), performed annually, assesses system upgrades, at all applicable voltage levels, required in the near-term planning horizon to address reliability needs.
Along with the Highway/Byway cost allocation methodology, the ITP process promotes transmission investment that will meet reliability, economic, and public policy needs intended to create a cost-effective, flexible, and robust transmission network which will improve access to the region’s diverse generating resources and facilitate efficient market processes. A list of ITP projects completed in 2013 can be found in Appendix E.
The first phase of the ITP process was completed with the Board of Directors’ acceptance of the ITP20 Report on January 25, 2011. The next phases of the ITP process were developed concurrently (ITP10 and ITPNT) in 2011 with the Board of Directors’ acceptance on January 31, 2012.
4.1: 2013 ITP20
The final 2013 ITP20 Report was approved by the SPP Board of Directors on July 30, 2013. For more information on the 2013 ITP 20-Year Assessment, see the full report available on SPP’s website (SPP.org > Engineering > Transmission Planning).
Five distinct futures were considered to account for possible variations in system conditions over the assessment’s 20-year horizon. The futures were approved by the Strategic Planning Committee (SPC) with input from the Economic Studies Working Group (ESWG). The futures evaluated as part of the 2013 ITP20 were:
$1.5B Benefit
$560M Cost
Southwest Power Pool, Inc.
18 2014 STEP Report
Future 1: Business-As-Usual - This future included state renewable mandates and targets as identified in the 2012 Policy Survey2 resulting in 9.2 GW of renewable resources modeled in SPP, load growth projected by load serving entities, and SPP member-identified generator retirement projections of approximately 4 GW. This future assumed no major changes to policies that are currently in place.
Future 2: Additional Wind - This future’s assumptions built upon the Business as Usual future assumptions. Instead of implementing current state renewable mandates and targets, a 20% Renewable Energy Standard (RES) was implemented for each region in the Eastern Interconnect with local renewable resources, resulting in 16.4 GW of renewable resources modeled in SPP. This provided an assessment of the transmission outlook if a similar federal renewable standard were implemented.
Future 3: Additional Wind plus Exports - Future 3 assumed SPP will produce and export 10 GW of wind resources above the 20% RES of Future 2 to assist other regions in meeting their RES. This 10 GW was exported to Entergy, PJM, Southern Company, and TVA.
Future 4: Combined Policy - This future examined various policy changes and impacts encouraging more “green” generation. A 20% RES for each region was implemented in this future, as well as a carbon constraint of $36/ton. A potential result of these policy changes was a more aggressive demand response/energy efficiency approach than the Business as Usual future. This was implemented through reductions in peak demand and energy usage, as well as a flatter load curve and higher load factor.
An annual 1% reduction to the growth of load was applied from 2021 through 2033 for the SPP region such that the load growth during these years was 0.3% instead of 1.3%. This was done to account for efficiencies gained in demand response/energy efficiency technology that might be expected if the carbon constraint was implemented. The
2 2012 Policy Survey
Southwest Power Pool, Inc.

decrease in annual energy percentage was approximately half of the decrease in peak demand percentage resulting in a higher load factor than the Business as Usual future.
Future 5: Joint SPP/MISO Future - The joint future parameters were developed by the SPP ESWG and the MISO Planning Advisory Committee (PAC). The ESWG and PAC determined the joint model should reflect “business as usual” conditions. This future was based on the same guidelines as Future 1 (normal load growth, state targets for renewable generation, etc.). While the joint future was similar to Future 1, it was not absolutely the same. Some of the assumption values varied from Future 1 due to collaboration with MISO for the joint future. These Future 5 differences included additional transmission constraints outside of SPP, natural gas prices approximately 4 cents less than Future 1 gas prices and more generation in the MISO region of the resource plan than Future 1.
Data provided by MISO regarding the modeling of the MISO region was also leveraged in the other futures to improve the representation of the MISO region in the SPP model.
The recommended 2013 ITP20 portfolio was estimated at $560 million in engineering and construction cost and included projects needed to meet potential reliability, economic, and policy requirements. Those projects, with a total estimated net present value revenue requirement of $845 million, are expected to provide net benefits of approximately $1.5 billion over the life of the projects under a Future 1 scenario containing 9.2 GW of wind capacity.
The complete list of recommended 2013 ITP20 projects can be found in Appendix C of this report.
4.2: 2015 ITP10
The second phase of the ITP study process includes the ITP 10-Year Assessment performed under the requirements of Attachment O, Section III of the SPP OATT. The approved portfolio includes projects ranging from comprehensive regional solutions to local reliability upgrades to address the expected reliability, economic, and policy needs of the studied 10-year planning horizon.
The 2015 ITP10 study process will continue through 2014 with the goal of approval by the BOD in January 2015.
4.3: 2014 ITP Near-Term (ITPNT)
The 2014 ITPNT analyzed the SPP region’s immediate transmission needs over the near-term planning horizon. The ITPNT assessed: (a) regional upgrades required to maintain reliability in accordance with the NERC TPL Reliability Standards and SPP Criteria in the near-term horizon; (b) zonal upgrades required to maintain reliability in accordance with more stringent individual Transmission Owner planning criteria in the near-term horizon; and (c) coordinated projects with neighboring Transmission Providers. ITPNT projects are reviewed by SPP’s Transmission Working Group (TWG), Markets and Operations Policy Committee (MOPC), and approved by the Board of Directors. Following Board of Directors’ approval, staff will issue Notification to Construct (NTC) letters for upgrades that require a financial commitment within the next four-year timeframe.
SPP developed models for the 2014 ITPNT analysis based on the SPP Model Development Working Group (MDWG) models, for which Transmission Owners and

Balancing Authorities provided generation dispatch and load information. The study scope3 – approved by the TWG on December 19, 2012 – contains:
The years and seasons to be modeled, including 2014, 2015, and 2019;
Treatment of upgrades in the models;
Scenario cases to be evaluated;
Description of the contingency analysis and monitored facilities; and
Any new special conditions that are modeled or evaluated for the study including the development of the 2019 summer peak model for SPP’s Consolidated Balancing Authority (CBA) dispatch.
SPP performed analyses identifying potential bulk power system reliability needs. These findings were presented to Transmission Owners and the Transmission Working Group (TWG) to solicit transmission solutions to the potential issues identified. Also considered were transmission solutions from other SPP studies, such as the Aggregate Transmission Service Study and Generation Interconnection processes. From the resulting list of potential solutions, staff identified the optimal regional solutions for potential reliability needs. Staff presented these solutions for member and stakeholder review at SPP’s November 2013 planning summit. Through this process, SPP developed a draft list of 69 kV and above solutions necessary to provide reliable service in the SPP region in the near-term planning horizon.
The map in Figure 4.1 shows the draft ITPNT solutions in correlation to the areas identified with reliability criteria violations. The complete list of 2014 ITPNT projects is located in Appendix D of this report.

Section 5: Balanced Portfolio
The SPP Board of Directors approved the Balanced Portfolio projects in April 2009 and directed staff to finalize the Balanced Portfolio Report in accordance with the SPP Tariff and then issue Notifications to Construct (NTC). The NTCs were issued in June 2009.
The Balanced Portfolio was an initiative to develop a group of economic transmission upgrades benefitting the entire SPP region and to allocate those project costs regionally. The benefits of this group of 345 kV transmission upgrades have been demonstrated by model analysis to outweigh the costs, and the regional cost sharing creates balance across the SPP region. For more information on the Balanced Portfolio, see the full report (SPP.org > Engineering > Transmission Planning).
Figure 5.1 below is a graph of the total estimated costs attributed to Balanced Portfolio projects for the 2014 STEP and previous years. The estimated project costs are affected by the completion of projects, as seen in Table 5.1, and adjustments in project cost estimates by Project Owners.

Section 6: High Priority Studies
6.1: SPP Priority Projects
In 2010, the SPP Board of Directors and Members Committee approved for construction a group of "priority" high voltage electric transmission projects estimated to bring benefits of at least $3.7 billion to the SPP region over 40 years. The projects will improve the regional electric grid by reducing congestion, better integrating SPP‟s east and west regions, improving SPP members‟ ability to deliver power to customers, and facilitating the addition of new renewable and non-renewable generation to the electric grid. For information on Priority Projects, see the full report (SPP.org > Engineering > Transmission Planning).
Figure 6.1 below is a graph of the total estimated costs attributed to Priority Projects for the 2014 STEP and previous years. The estimated project costs are affected by the completion of projects and adjustments in project cost estimates by Project Owners. No Priority Projects were completed in 2013.

Section 7: Sponsored Upgrades
Sponsored upgrades are Network Upgrades requested by a Transmission Customer or other entity which do not meet the definition of any other category of Network Upgrades. Any entity may request a Sponsored Upgrade. SPP will evaluate the impact of any Sponsored upgrade on transmission system reliability and identify any necessary mitigation of these impacts. The proposed Sponsored upgrades will be submitted to the MOPC and BOD for endorsement.
The Project Sponsor must be willing to assume the cost of the Sponsored upgrade, study costs, and any cost associated with necessary mitigation.
No Sponsored upgrades were completed in 2013.

Section 8: Regional Cost Allocation Review (RCAR)
The Regional Allocation Review Task Force4 (RARTF) report recommended that if the Regional Cost Allocation Review (RCAR) of “[a]ll SPP projects that have been issued an NTC since June 2010 and all projects that have not received an NTC that have an in-service date of ten years or less from the year of the report” shows that a zone is below the 0.8 B/C ratio Section 4.1 of the RARTF Report then “SPP staff should evaluate, and recommend possible mitigation remedies for the zone.”
The RCAR Report referenced 5 zones that are below the 0.8 benefit to cost ratio for projects with NTCs and all projects without NTCs that have an in-service date of ten years or less. Those zones are:
City Utilities of Springfield
The Empire District Electric Company
Grand River Dam Authority
Lincoln Electric System
Sunflower Electric Power Corporation
Figure 5 on page 22 of the RARTF Final Report, provided a list of mitigation remedies that SPP staff should consider for study and to be made part of the report. SPP Staff and the RARTF recommended the RCAR Report be finalized in October 2013 in order to incorporate and include the finding in SPP’s current ITP10 assessment that commenced in July 2013. This recommendation was in-line with the direction of the RARTF Report approved in January 2012 as described below.
As stated in the report, the first two remedies for SPP staff to consider for City Utilities of Springfield, Empire District Electric Company, Grand River Dam Authority, Lincoln Electric System, and Sunflower Electric Power Corporation as a part of the RCAR Report is the “[a]cceleration of planned upgrades” and “[i]ssuance of NTCs for selected new upgrades.”
Furthermore, Section 4.2 of the RARTF Report states, “[a]dditionally, the RARTF recommends that any Regional Cost Allocation Review, which shows that a zone is above the 0.8 threshold in Section 4.1, but below a 1.0 B/C ratio, should be used and considered as a part of SPP’s transmission planning process in the future.”
Because SPP’s 18-month ITP10 Assessment has commenced and remedies contemplated in the RARTF Report include the evaluation of transmission upgrade remedies, SPP Staff recommended the RCAR Report be finalized and considered in SPP’s current ITP10 Assessment in collaboration with deficient zones and SPP Stakeholders.
4 Regional Allocation Review Task Force Charter
Southwest Power Pool, Inc.
29
In addition to this recommendation, SPP staff and the RARTF recommended that a second RCAR process [RCAR II] be commenced and worked in parallel with the current ITP10 Assessment which is expected to be completed in January 2015. This will allow SPP staff to follow the directions contained in Sections 4.2 and Section 5.1 of the RARTF Report through ITP10 while utilizing RCAR II as a means to understand whether proposed remedies approved in the ITP10 provide equity for certain zones. If RCAR II does not show that adequate remedies exist, SPP staff, deficient zones, and SPP Stakeholders can begin the process of analyzing additional potential remedies for any zone below the threshold. The RCAR II report will be completed either (i) shortly after the ITP10 is completed, if cost estimates are to be used in the RCAR II analysis; or (ii) shortly after the completion of the competitive solicitation process, if the RFP results are to be used in the RCAR II analysis.

Section 9: Interregional Coordination
9.1: Integrated System Integration Study
The Integrated System (IS) is comprised of three utilities: Western Area Power Administration Upper Great Plains (WAPA), Basin Electric Power Cooperative, and Heartland Consumers Power District. These three utilities operate under a tariff administered by WAPA. In the third quarter of 2013 SPP performed a study to evaluate the reliability and transmission needs of the (IS) in the event the IS were to join the SPP RTO.
The study was performed to provide SPP staff, stakeholders, and the IS with data and information regarding the potential integration of the IS as transmission-owning members of SPP. A potential integration date of October 2015 was assumed for this study. The study had two primary objectives:
1. Evaluate the reliability of the IS’s transmission system at the time of the assumed integration date; and
2. Identify the “need-by” date of the IS planned transmission projects using SPP’s planning models and project timing criteria.
Reliability Assessment
SPP evaluated the reliability of the IS’s transmission system for NERC Category A, Category B, and select Category C5 conditions using the SPP Criteria. This analysis was performed using SPP’s Scenario 0 and Scenario 5 planning models which were updated by the IS to ensure accurate modeling of the IS transmission system. After SPP identified potential reliability needs, these potential needs were provided to the IS so mitigations could be provided and tested. The IS provided an acceptable mitigation for each potential reliability need identified by SPP. The results of this analysis are summarized in the tables below.

9.2: Interregional Requirements of Order 1000
In July of 2013 SPP filed at FERC procedures to meet the interregional requirements of Order 1000. This filing included enhancements to the SPP-MISO Joint Operating Agreement (JOA), a new section in Attachment O of the SPP Tariff to incorporate coordination and cost allocation procedures with the Southeastern Regional Transmission Planning (SERTP) region, and enhancements to Attachment O to outline a regional approval process and regional cost allocation for interregional projects.
9.3: ITP Seams Coordination Enhancements
In 2013, SPP enhanced the ITP process by including additional opportunities for coordination with SPP’s neighbors. The enhancements provide an opportunity for additional coordination with SPP’s neighbors throughout multiple stages of the ITP including model development, issues identification, and solution development. In each of these stages of an ITP study SPP will coordinate with each neighbor on a similar basis as that of SPP stakeholders. The value provided to the ITP process from this additional coordination is better modeling of neighboring regions and more accurate issues identification for potential seams projects as solutions to those issues.
9.4: Eastern Interconnection Planning Collaborative
SPP is a participating Planning Authority (“PA”) in the Eastern Interconnection Planning Collaborative (EIPC). The activities of the EIPC can be found on the EIPC website at www.eipconline.com.
The EIPC produced a report in December 2013 that details the efforts of the EIPC Steady State Modeling and Load Flow Working Group (SSMLFWG) to produce a 2018 and a 2023 Roll-Up Integration Case of the Eastern Interconnection and provide a summary of the assessments performed. The SSMLFWG includes representatives from each NERC registered PA that is a party to the EIPC Analysis Team Agreement.
The Roll-Up Integration Case represents the base case for the Eastern Interconnection and a starting point for additional analysis. This base case will then be evaluated against various scenarios that will be developed with stakeholder input. The Roll-Up Integration Case is an integrated model of the expansion plans for the Eastern Interconnection as they existed in 2013, not a single “blueprint” for expanding the system. These cases provide solved power flow modeling suitable as a starting point for transmission analysis on an interconnection-wide basis and they are available to all stakeholders to perform their own analyses provided they have CEII clearance.
Southwest Power Pool, Inc.

As with all power flow models, the 2018 and 2023 roll-up integration cases are a representation of the power system for a particular “snapshot” in time (2018 and 2023 Summer Peak hours) based upon actual facilities and planning forecasts as they existed to meet NERC Reliability Standards at the time the model was developed. The SSMLFWG utilized transmission plans that were provided by each PA as the source of data for model development. These existing transmission plans are a product of each participating PA and the FERC approved regional transmission planning processes for each of the participating EIPC members (as applicable) and extend out through the year 2023. It should be noted that loads as well as generation and demand-side resources are inputs into the transmission expansion plans developed by each Planning Authority, and that these inputs are provided by the respective Load Serving Entities (LSEs), market participants, or other applicable entities within each Planning Authority’s jurisdiction. Because these inputs are continuously changing, the local and regional transmission plans will necessarily also continuously change resulting in them being more current than can be achieved in wide-area modeling. Nonetheless, wide-area modeling, such as the 2018 and 2023 roll-up integration cases, provides a sound basis for assessing inter-dependencies between and among regions which may not be achievable through local assessments individually. Potential constraints and efficiencies identified through inter-regional analysis are valuable inputs into local and regional processes, where they can be assessed for inclusion into regional transmission expansion plans.

Section 10: Sub-Regional Planning
Based on FERC Order 890 and Section III.2.b of Attachment O of the OATT, sub-regional areas were defined and local area planning meetings were held during 2013 in conjunction with the SPP planning summits.
The purpose of local area planning meetings is to identify unresolved local issues and transmission solutions at a more granular level than are accomplished at general regional planning meetings. Local area planning meetings provide stakeholders with local needs the opportunity to give advice and recommendations to the Transmission Provider and Transmission Owners. Local area planning meetings are open, coordinated, and transparent, providing a forum to review local area planning criteria as specified in Section II of the OATT, Attachment O. Feedback offered at each sub-regional meeting is taken into consideration by SPP staff when developing the regional reliability plan.
10.1: Stakeholder Process and Forums
Notices for the sub-regional planning meetings are posted on SPP.org and distributed to the appropriate email distribution lists. Sub-regional planning meetings are open to all entities. Any regulatory agency is invited and encouraged to participate. The map above represents the three SPP local areas.
2013 Sub-Regional Meetings
SPP held sub-regional planning meetings in Little Rock, AR as part of the May and November planning summits. Meetings for all sub-regions were held concurrently in breakout sessions during the spring and fall gatherings. Subject matter experts from SPP staff were present at all of the meetings to receive suggestions, answer questions, and discuss any concerns that stakeholders had about the transmission needs in their respective region.

Section 11: Project Tracking
11.1: Business Practice 7060
Applicable to projects issued an NTC on or after January 1, 2012, the MOPC approved Business Practice 7060 on March 27, 2012. The Business Practice commenced a cost estimation process defined by a tiered approach for project cost estimates based upon the level of project definition that is known. It also introduced the Notification to Construct with Conditions (NTC-C) issued to applicable projects, projects with an estimated cost of $20 Million or greater and a nominal operating voltage greater than 100 kV. The table below lists the cost estimate stage definitions.

Table 11.1: BP 7060 Cost Estimate Stage Definitions
The precision bandwidths defined in Business Practice 7060 are used as guidelines for NTC review triggers. For a project that is issued a NTC-C, an automatic review of the project is initiated if the ±20% precision bandwidth of the cost estimate that is received after NTC-C issuance, called the NTC-C Project Estimate (CPE), exceeds the ±30% bandwidth of the cost estimate previously submitted during the study phase of the project, titled the Study Estimate.
11.2: Project Cost Working Group
Business Practice 7060 also defined the role of the Project Cost Working Group (PCWG) for reviewing projects that have experienced a cost variance that exceeds ±20% of the established baseline estimate. The PCWG will initially be responsible for only applicable projects. If the PCWG recommends a restudy and/or changes or revocation of a NTC, the recommendation to the MOPC would follow SPP’s existing processes for approval to the
Southwest Power Pool, Inc.
36 2014 STEP Report
BOD. The BOD will make the final determination on whether to restudy and/or change or revoke the NTC.
The PCWG is also responsible for maintaining the Standardized Cost Estimate Reporting Template (SCERT) developed to provide consistency of cost estimates and facilitate the Project Tracking process. The SCERT is to be utilized by Transmission Owners for all project cost estimates and applicable monthly/quarterly updates.
11.3: NTC Letters Issued in 2013
The NTC informs transmission project owners of their responsibility for constructing BOD approved network upgrades. NTCs are needed by project owners to assist them in the regulatory and cost recovery process. In 2013, 25 NTCs were issued with current estimated engineering and construction costs of $1.64 billion for 86 projects to be constructed over the next 5 years through 2018. Of this $1.64 billion, the project cost breakdown is as follows:
$1.02 billion for Regional Reliability;
$1.12 million for Zonal Reliability;
$13.65 million for High Priority; and
$604.64 million for ITP10 projects.
A list of the NTCs issued in 2013 can be found in Appendix B.
11.4: Projects Completed in 2013
After the SPP Board of Directors approves transmission expansion projects or once Interconnection or Network Integrated Transmission Services Agreements are filed with FERC, SPP issues Notifications to Construct (NTC) letters to appropriate Transmission Owners. SPP actively monitors the progress of approved projects by soliciting feedback from project owners. Seventy-nine (79) upgrades were completed as of December 3, 2013. The breakdown includes:
59 ITP ‐ $274.9 million
14 Transmission Service ‐ $65.7 million
