PJM provides proposal window update to TEAC

1341

PJM updated stakeholders on the opening of the market efficiency and reliability proposal windows of the Regional Transmission Expansion Plan (RTEP)  at the May 3 Transmission Expansion Advisory Committee (TEAC).

Market Efficiency

PJM will present input assumptions for load forecast, generation expansion, demand resources, fuel/emissions price forecasts, and financial parameters at the June TEAC.

The study years are: 2019 and 2023 (approved RTEP projects for accelerations and modifications) and 2019, 2023, 2026, 2029 and 2033 for study new system enhancements.

Reliability Analysis

PJM anticipates administering two 2018 proposal windows for reliability violations.

The first will be a standard 60-day window, with a target opening in early June. It will include all analysis results excluding N-1-1 voltage.

The second window, an abbreviated, targeted 30-day window in early July, will include only N-1-1 voltage results and will be targeted to close at the same point as the earlier 60-day window.

PJM posted the preliminary 2023 summer peak RTEP base case and input files in April and the preliminary base case (N-1 thermal and voltage) and generator deliverability results the first week of May.

Load deliverability studies are under way, and the N-1-1 thermal studies will start shortly.

For winter and light load, PJM has reviewed the base cases and is continuing work on some final clean-up of the cases. It anticipates starting analysis within the next week.

For generation deactivation, PJM reviewed plans for the transmission upgrades that will enable the planned FirstEnergy Solutions retirements. Operational flexibility allows PJM to bridge any delays with the transmission upgrades.

PJM also presented interregional coordination updates.
