On March 2, 2021, in Docket No. ER21-1243-001, PJM filed an errata to the proposed rules relating to Price Responsive Demand originally filed on March 1, 2021. This errata corrects an eTariff metadata error in which PJM inadvertently indicated that the effective date for the RAA - Definitions was November 20, 2020. The effective date was corrected to match the intended date of June 1, 2021.

On March 1, 2021, in Docket No. ER21-278-001, PJM submitted responses to the Commission’s December 22, 2020 deficiency letter regarding PJM’s FPA section 205 filing to establish an Effective Load Carrying Capability (ELCC) construct for determining the relative amount of capacity that variable, limited duration, and combination resources may offer in PJM. PJM requested an effective date of July 1, 2021 for the RAA and Tariff revisions, and an order on the revisions by May 1, 2021. In accordance with section 388.112 of the Commission’s regulations, PJM has requested confidential treatment for certain data provided in an appendix to the responses, and the confidential data will be made available to participants in this proceeding upon their execution of the Protective Agreement PJM included with the filing.

On March 1, 2021, in Docket No. ER21-1243-000, PJM submitted proposed revisions to PJM’s Open Access Transmission Tariff, Amended and Restated Operating Agreement of PJM Interconnection, L.L.C. and the Reliability Assistance Agreement Among Load Serving Entities in the PJM Region to amend the Price Responsive Demand rules so that there is no longer a need to differentiate between a Load Serving Entity versus any other PJM Member that provides PRD. This proposed amendment will allow PRD Credits to be allocated directly to the PRD Provider rather than only to associated Load Serving Entities.
