SSO Auctions

The raw wholesale auctions that set Ohio's Standard Service Offer. Each utility group runs a competitive bidding process under PUCO oversight; the clearing prices below feed directly into the Price-to-Compare you see on customer bills.

32 auctions tracked · 4 utility groups

Clearing price ≠ your PTC. The auction clearing price is a wholesale energy rate; the consumer-facing Price-to-Compare adds capacity riders, line-loss factors, and per-territory adjustments. A 12-month auction at 8.5¢ can land on customer bills as a 9.5¢ PTC once those layers are stacked. See /history for the customer-facing rate over time.

    First of two SSO auctions for the 2026/2027 DY under ESP V (12-month product, no 36-month bids)

    Effective Jun 1, 2026May 31, 2027
    Clearing price

    Auction date is approximate (December 2025). Duke's ESP V eliminated 36-month products and shifted the second-of-DY auction earlier to reduce supplier risk. Public clearing-price disclosure was not located in primary sources.

    Full-requirements SSO supply, 12-month product for 2026/2027 DY

    Effective Jun 1, 2026May 31, 2027
    Clearing price
    9.70¢/kWh

The December 2025 PJM capacity auction subsequently cleared at the FERC cap of $333.44/MW-day, which will further pressure later auctions in the ESP V ladder.

    Effective Jun 1, 2023May 31, 2024
    Clearing price
    11.34¢/kWh

    Effective Jun 1, 2023May 31, 2024
    Clearing price
    12.00¢/kWh

    Held under ESP IV. Cleared at $119.98/MWh, hedging 45% of the 2023/2024 SSO load. The high clearing price drove the ~10.3¢/kWh blended PTC that hit bills in June 2023 and triggered the widely reported ~30% rate hike.

    Effective Jun 1, 2023May 31, 2024
    Clearing price
    12.23¢/kWh
    all 3 territories

    Highest FirstEnergy SSO clearing price in recent memory. Driven by post-invasion European gas demand pulling LNG out of the Atlantic basin and elevated PJM forward curves. Result was the dramatic ~110% PTC increase that took effect June 2023 — the catalyst for NOPEC briefly suspending its standard product.
