FERC rejected a rehearing request of its order approving SPP’s proposed one-time accelerated study of shovel-ready interconnection requests, sustaining its original 2025 decision.

FERC ruled that MISO is free to continue using its interconnection queue fast lane, shutting down rehearing requests from several clean energy organizations.

MISO is considering a new type of interconnection agreement for generation built on site and strictly for new large loads.

FERC largely approved compliance filings by three California investor-owned utilities related to interconnection queue requirements.

ISO-NE’s first interconnection cluster study held under new Order 2023 rules is made up mostly of large battery resources and contains only five wind and solar projects.

Capacity auction reforms, a new asset condition reviewer role, parallel transmission planning efforts, new reserve products, Pay-for-Performance changes and interconnection modifications are likely to be on the docket for ISO-NE in 2026.

MISO announced that its first interconnection queue express lane application window turned up 47 projects at a little more than 26.5 GW of proposed new capacity, with natural gas generation accounting for about 20 GW.

PJM’s Markets and Reliability Committee endorsed by acclamation a PJM proposal to rework how the RTO determines whether a new generation point-of-interconnection falls under federal or state jurisdiction.

SPP’s Board of Directors has approved a tariff change establishing an integrated, three-year transmission planning cycle that represents a “first-in-the-country” mechanism.

SPP stakeholders unanimously approved a tariff change that replaces current planning processes with an integrated three-year cycle composed of long-term and annual studies.
