Capacity Market Issues

December 31, 2025 Form 10-K page 12, March 31, 2026 Form 10-Q page 66 and June 30, 2026 Form 10-Q page 75. In July 2026, PJM proposed tariff revisions to FERC to implement a proposed “Reliability Backstop Procurement” framework to address the 6.8 GW resource shortfall for the 2028/2029 delivery year. This procurement mechanism seeks 15-year commitments from new generation resources, with costs passed to load-serving entities and end-use customers, including data centers.

In September 2026, FERC issued an order finding key components of the RBP filing to be just and reasonable, while rejecting other components. FERC also encouraged PJM to make a revised filing within 30 days based on the guidance it provided. At the end of October 2026, PJM made a revised RBP filing, seeking FERC approval by January 29, 2027. Assuming FERC approval, PJM plans to run the RBP auction on March 1, 2027.

In August 2026, PJM filed at FERC for approval of rules that would allow for curtailment of new “large load” customers, including data centers, during times of peak demand on the system if those customers do not have new generation committed to supply their demand. In October 2026, FERC issued an order rejecting the principal components of PJM’s filing, including the provisions permitting the curtailment of new large load customers. In its order, FERC found significant deficiencies with PJM’s proposal, including that key aspects fell outside of FERC’s jurisdiction under the Federal Power Act.

Energy Efficiency, Triennial Review

December 31, 2025 Form 10-K page 14, March 31, 2026 Form 10-Q page 66 and June 30, 2026 Form 10-Q page 75. In April 2026, BPU Staff issued its straw proposal for a one-year extension to the second triennium of energy efficiency programs rather than issuing a framework for the third triennium to accommodate the time needed for the BPU to establish the third triennium framework. In July 2026, the BPU issued the final framework for the extension which allowed for utilities to file for alternative proposals, including but not limited to ROE and savings targets. In September 2026, PSE&G filed its proposed program extension, with alternatives. We cannot predict the outcome of this matter at this time.
