SPP’s Western Energy Imbalance Service market saw “very limited growth” in its first 13 months, SPP’s MMU said in its first annual report on the market.

SPP’s Board of Directors approved stakeholders’ recommendation to issue a notification to construct a 345-kV double-circuit transmission project in New Mexico.

Stakeholders are concerned over the comments MISO plans to submit on FERC’s recently proposed transmission planning rule.

FERC proposed allowing RTOs to share credit information about market participants, fulfilling a request the grid operators made at a 2021 technical conference.

SPP regulators have approved a recommendation for three DC ties that will connect the RTO’s Eastern and Western Interconnection footprints.

SPP’s Board of Directors has sided with staff in approving an increase of the RTO’s planning reserve margin to 15%, effective next year.

Persistent triple-digit temperatures across much of Texas have forced ERCOT to issue yet another operating condition notice as it flirts with 80-GW demand.

SPP and its members have agreed to boost the reserve margin to 15% but remain at odds over the timing of the increase following "contentious" MOPC discussions.

SPP has again declared a resource advisory for its footprint July 25 as searing heat continues to roast the Southern Plains.

ERCOT demand set a new demand mark for the 11th time this year as a heat dome over the Southern Plains continues to produce record-breaking temperatures.
