The Daily Baseload Brief

PJM is set to file a second FERC proposal on 7 August 2026 that would allow the grid operator to curtail large loads - principally data centers - that have not secured their own power supplies when the system approaches emergency conditions^[2].

Data centers that come online after 1 June 2027 without on-site generation will be subject to curtailment ahead of standard pre-emergency load management under the Interim Resource Adequacy Service proposal, according to PJM spokesman Jeffrey Shields. The filing follows PJM's 31 July 2026 backstop auction proposal, which targets a 6.8 GW capacity shortfall from the 2028/2029 delivery-year auction with a one-time procurement window running 30 September to 21 October 2026^[2].

Taken together, the two filings amount to a structural shift in how PJM expects large loads to connect to the grid. Analysts at Latitude Media described the combined framework as designed to push data centers to treat bring-your-own-generation as the default rather than the exception^[2]. PJM's load forecast projects new large-load demand will grow by approximately 70 GW by 2038, against a backdrop of roughly 15 GW of generation retired since 2022. FERC's response to the proposals is expected to influence utility capital investment and data center development timelines across PJM's 13-state footprint.

On the demand-side economics, a report published 4 August 2026 by Energy Innovation - a nonpartisan think tank - found that meeting US electricity demand growth with clean energy rather than fossil fuels would save $5 billion per year by 2030^[1]. The analysis, commissioned alongside Vote Solar, projects that US peak electricity demand will rise 24% by 2030, driven by data centers, industrial growth, and electrification^[1]. The fossil-fuel pathway would add $29.7 billion annually to customer bills by 2030, compared with the clean energy scenario, which the report models as reliably meeting load growth at lower total system cost^[1].

The two developments sit on opposite sides of the same pressure point: a grid facing unprecedented load growth, a capacity market that has already failed to clear its reliability requirement, and a regulatory framework that is now explicitly pricing the cost of inaction onto the loads causing the strain. FERC's ruling on the curtailment proposal - and whether it approves the backstop auction timeline - will be the next material signal for developers and investors across the PJM footprint.
