Regional grid operator seeks approval to update capacity market timing and enhance reliability through tighter alignment of auctions and delivery periods.
In early January 2026, ISO New England (ISO-NE) filed the first phase of capacity auction reforms with the Federal Energy Regulatory Commission. The reforms are designed to modernize the region’s capacity market by shortening the time between auctions and delivery periods, improving forecast accuracy, and helping ensure that resources committed in auctions are operational and ready when needed. The filing also proposes streamlining the deactivation process for capacity resources, shortening the window from four years to one. ISO-NE’s capacity auction reforms are meant to strengthen reliability, reduce the prevalence of “phantom” capacity entries, and provide clearer signals for investment in new resources.
ISO-NE filed the first phase of capacity market reforms with FERC in January 2026.
Reforms will shift capacity auctions closer to delivery periods for more accurate planning.
The deactivation timeline for resources exiting the market would shorten from four years to one.
Better forecasts and updated auction schedules aim to improve reliability outcomes.
ISO-NE’s reforms are part of broader efforts to adapt wholesale market design to evolving grid conditions.
“Reforming capacity auctions and aligning them more closely with delivery requirements is expected to improve reliability and investment signals for market participants."
CONCLUSION
Capacity market reforms that improve timing and transparency can have far-reaching effects on grid planning and investment decisions. By reducing mismatches between commitments and actual delivery periods, these regulatory changes help ensure that capacity is reliable and resources are available when needed. For advanced transmission planning, including HVDC corridors and other major interregional projects, strong market design and regulatory clarity contribute to predictable planning frameworks that support investor confidence, cost allocation, and coordinated infrastructure build-out.
