FERC said it needs more explanation behind MISO’s plan to use a capacity accreditation that would accredit resources based on a combination of their projected availability and historical performance during periods of high system risk.

FERC approved NYISO’s proposed tariff revisions to more accurately accredit natural gas resources’ capacity, but the commission delayed their implementation until 2026.

A relatively low turnout of constructed capacity in recent years could deepen a potential 2.7-GW capacity deficit in summer 2025 to more than 14 GW by summer 2029, MISO and OMS revealed in a five-year projection.

SPP’s resource adequacy stakeholder group has moved several policies that indicate the team’s work is “coming home” after months of presentations and discussions.

Stakeholder voices criticizing the design of MISO’s proposed, probabilistic capacity accreditation outnumbered those expressing support before FERC.

SPP’s effort to impose capacity accreditation methodologies for thermal and renewable resources has drawn protests from public-interest and clean-energy groups at FERC.

MISO’s imminent filing for a new capacity accreditation is a crucial first step to get ready for a more complex and challenging future, executives told attendees during March Board Week.

NYISO initiated steps toward integrating hydrogen into its market, aiming for technology-agnostic rules to foster clean energy innovation.

MISO is determined to file with FERC by the end of March to introduce a probabilistic capacity accreditation that’s controversial among its stakeholders.
