PJM’s 2027/2028 Base Residual Auction (BRA), released Dec. 17, cleared at a record‑high, FERC‑capped price of (333.44$/MW\text{-}day) across the entire PJM footprint, procuring about 134,479 MW of unforced capacity but still falling short of PJM’s stated reliability requirement.

What the auction just did

• The clearing price hit the maximum allowed cap of (333.44$/MW\text{-}day), slightly above last year’s already‑elevated (329.17$/MW\text{-}day) (about a 1.3% increase), and it applies uniformly across all PJM zones for 2027/28.
• PJM procured roughly 134,479 MW of unforced capacity (UCAP) across generation, demand response, and other resources, but that total still falls about 6,623 MW short of the reliability requirement for a one‑event‑in‑10‑years standard, underscoring a tightening supply‑demand balance.
• The cleared resource mix is heavily thermal: about 43% natural gas, 21% nuclear, 20% coal, with smaller contributions from demand response (~5%), hydro (~4%), wind (~2%), oil (~2%) and solar (~1%), influenced by updated ELCC ratings that change how much capacity value each type gets.

Key signals for businesses in PJM

• Higher capacity cost baseline is locked in for 2027/28. With prices again at the cap, capacity will remain a large and growing slice of customer bills, especially for medium and large C&I accounts whose capacity tags reflect prior peak usage; even though this specific auction is only ~1.3% above last year, it cements a structurally high price level following the earlier jump to the cap.
• Reliability margin is thin, so volatility risk is elevated. Clearing below the reliability requirement means the system is running with less reserve than PJM’s target, which heightens the stakes around extreme weather, data‑center growth, and electrification loads; businesses should plan for potential scarcity‑driven price spikes in both capacity and energy if conditions tighten further.
• Policy and structural changes are on the table. The fact that prices are at a legal cap negotiated after earlier litigation, and would otherwise be materially higher, is driving renewed scrutiny of AI/data‑center load growth and PJM market rules, which could translate into future rule changes that shift cost responsibility or alter how peak demand and capacity tags are calculated.

What it practically means for you

• Expect capacity to remain a prominent driver of total delivered cost in the 2027/28 delivery year, even if the incremental year‑over‑year increase is modest compared with the earlier step‑change in the cap; budget owners will feel it most in high‑load, demand‑heavy facilities.
• The auction reinforces the value of:
  • Reducing coincident peak demand to lower future capacity tags (PJM 5CP‑style strategies, demand response participation, and load flexibility).
  • Accelerating efficiency, controls, and behind‑the‑meter generation or storage to shrink exposure to both energy and capacity cost components over the next several years.

Businesses can start limiting risk today by attacking both the cost side (capacity tag and supply strategy) and the operational side (flexibility and resilience).

Cut your future capacity tag

• Monitor and respond to PJM coincident peaks (5CP/PLC): use alerts and forecasting to curtail during likely peak hours (typically hot summer weekdays in the afternoon) so next year’s capacity tag is lower.
• Implement peak‑load management tactics: pre‑cool buildings, stagger equipment start‑ups, shift noncritical production outside 2–6 p.m. on high‑risk days, and use automation/EMS to execute these strategies consistently.

Use demand response and flexible load

• Enroll in PJM demand response programs (through a CSP/aggregator) to get paid for curtailing during emergencies or reliability events, turning flexibility into a revenue stream that offsets higher capacity prices.[8][9][10][11]
• Aggregate flexible loads (HVAC, pumping, process loads, cold storage, etc.) to deliver meaningful, reliable reductions without harming core operations.

Lock in smarter supply and hedges

• Review contract structures with suppliers or brokers: compare block‑and‑index vs. fully fixed options, and ensure capacity and transmission pass‑throughs are clearly understood and modeled through 2027/28.
• Consider layering hedges (laddering terms, partial blocks) rather than a single “all‑in” bet, so you’re not overexposed if prices or policy shift again.

Invest in efficiency and on‑site resources

• Accelerate energy efficiency projects (lighting, controls, HVAC optimization, process improvements) that permanently lower kW and kWh—cutting both energy and capacity charges every year.
• Evaluate distributed energy resources: CHP, solar, and batteries can shave peaks, provide backup during tight conditions, and sometimes participate in PJM markets for additional revenue.

Strengthen planning, forecasting, and governance

• Build a multi‑year energy budget that explicitly includes current PJM capacity prices and potential volatility from reliability shortfalls, then stress‑test against high‑demand scenarios.
• Formalize governance: assign an internal “energy owner” and partner with an energy consultant to handle peak alerts, DR enrollment, project ROI modeling, and evolving PJM rule changes.
