PJM Presents Long-term Planning Proposal

PJM presented a quick fix proposal to introduce a new long-term transmission planning approach that would include a longer 15-year horizon and consider state legislation that could affect generator participation in RTO markets. 

In giving a first read of the proposal during the Dec. 9 Planning Committee meeting, PJM’s Michael Herman said it would establish five long-term scenarios:  

    • Two base cases 8 and 15 years in advance; 
    • Two 8- and 15-year scenarios assuming a medium amount of new entry prompted by state legislation; and 
    • One high new-entry scenario looking 15 years in advance and including policy goals not backed by legislation. The proposal includes changes to Manual 14B and 14F. 

The base scenarios would focus on the grid’s future reliability needs based on load forecasting, expected generation deactivations, and new resources in the interconnection queue and expected to be online within the scenario’s horizon.  

Thermal and voltage analysis would be performed on the 8-year base scenario, replacing the existing 10-year model for voltage analysis, and would be used to inform the 5-year Regional Transmission Expansion Plan (RTEP) near-term process. Thermal and some voltage analysis would be performed on the 15-year scenario. 

PJM’s Jonathan Kern said the proposal is meant to bolster PJM’s process for addressing localized reliability issues on the transmission grid rather than targeting global resource adequacy and create new scenarios to meet various goals. The RTO also would make changes to the near-term planning process to ensure the long-term approach is harmonized. 

“We want to have an efficient planning process, so we don’t want to have a big disconnect,” Kern said. 

The current two-year planning cycle would be extended to three years to reflect the increased number of scenarios and sensitivities. 

Exelon’s Alex Stern said this was the first time stakeholders had the opportunity to review proposed manual changes. He identified three challenges that have not been addressed:  

    • How projects that address both grid reliability needs and state policy goals would fit into the planning process;   
    • How PJM proposes to delineate between local reliability and regional reliability; and 
    • Where and how economic reviews will be applied. 

PJM plans to seek PC endorsement of the quick fix proposal during its Feb. 6 meeting and, if endorsed, bring it to the Markets and Reliability Committee later that month for a first read. The quick fix process allows an issue charge and problem statement to be voted on concurrently with a proposed solution. 

Paul Sotkiewicz, president of E-Cubed Policy Associates, expressed concerned about how often PJM has been using the quick fix process to propose manual changes in recent months and questioned the necessity of using it in this case. 

Stern said he was focused on providing substantive feedback, but conceded the manual changes likely will require a level of discussion beyond the quick fix process. He worried that questions surrounding PJM’s legal authority could put a cloud over any planning that flows from the changes, such that the long-term regional transmission planning analysis will be unable to produce feasible transmission projects. 

PJM reviewed proposed updates to the TO/TOP Matrix, which indexes standards that transmission owners and PJM must comply with and delineates responsibilities to ensure compliance. 

The changes include revisions to reflect emergency operations standards NERC approved in October under EOP-011-4, which includes operating plan requirements for emergencies related to “critical natural gas infrastructure loads that fuel a significant portion of … generation.” (See NERC Board Approves Cold Weather Standards.) 

If approved by the Transmission Owners Agreement-Administrative Committee (TOA-AC), the revised matrix would become effective April 1.

PJM Presents 2024 RTEP Timeline

PJM is building base cases for its 2024 Regional Transmission Expansion Plan (RTEP) and accepting proposed changes to its basic assumptions, such as modeling, as long as they are expected to have a significant impact on baseline studies. It also will accept corrections to its analytical files. Feedback can be provided through March, when PJM plans to begin the baseline studies.  

The RTO seeks to open an RTEP competitive window in June or July, including a potential retool of the baseline analysis if needed. Review and approval of project proposals is planned to occur between October and February 2025. 

Supplemental Projects

Exelon presented a project to replace a 230/69-kV transformer at its Atlantic City Electric Mickleton Substation for $5.9 million. The existing transformer was installed in 1987 and is experiencing insulation wear and cooling issues. The project, which has a projected in-service date of May 31, 2025, is in the engineering phase. 

Dominion presented a $12.3 million project to construct a new 230-kV Lost City substation to serve a data center planned in Henrico County, Va. The proposed facility would cut into the existing White Oak-Techpark Place 230-kV line and has an estimated in-service date of July 1, 2025. 

FirstEnergy presented several projects to replace transformers experiencing consistent maintenance issues or at the end of their lifespan. A 230/34.5-kV transformer at the Kittatinny Substation would be replaced with a 90-MVA unit for $7 million; two 230/34.5-kV transformers at the East Flemington Substation would be replaced with 125-MVA units for $14.36 million; and a 230/115-kV transformer at the Raritan River Substation would be replaced with a 224-MVA unit for $5.4 million. The projects also include related upgrades to relaying and breakers. 

The utility also proposed a project to replace relays and conductors at its Whippany Substation for $2.33 million to replace outdated equipment lacking spare parts.
