ERCOT’s Board of Directors approved an ISO request to correct real-time energy prices following a July event that caused brief market palpitations.

MISO laid out a more detailed proposal for how it will determine the capacity accreditation of energy storage resources under FERC Order 841.

The MISO market was competitive in 2017, but the RTO should do more to address increasing congestion and low capacity prices, Monitor David Patton said.

In his quarterly state of the market report, the PJM IMM said the results of the 2018 Base Residual Auction show the need to change its capacity offer cap.

MISO, commited to moving forward, said it plans to refile a plan to create external capacity resource zones with FERC by the end of the month.

FERC wants PJM’s capacity rules to be resolved by Jan. 4 and has dispatched staff to help the RTO and its stakeholders adhere to that timeline.

The SPP Board of Directors approved a Tariff change requiring non-dispatchable variable energy resources (NDVERs) to register as dispatchable (DVERs).

ERCOT executives said that system generation has overperformed during the summer, helping the grid operator meet demand during July’s record heat.

FERC rejected MISO’s proposal to create external zones for its annual capacity auction but left the door open for a revised plan in the future.

The Western Energy Imbalance Market saw financial benefits soar to a record $71.2 million in the second quarter, according to a CAISO report.
