The Arizona legislature passed a bill that would close the door to electric retail competition, but lawmakers said the conversation on deregulation isn't over.

FERC ordered CAISO, ISO-NE, MISO, NYISO, PJM and SPP to report on how system needs are changing with their shifting resource mixes and how they will meet them.

Rising natural gas prices and extreme weather pushed wholesale electricity prices higher in 2021, FERC said in its annual State of the Markets report.

ISO-NE's Order 2222 compliance filing has been criticized by environmental groups and renewable advocates who say it fails to meet the goals laid out by FERC.

FERC ordered PacifiCorp to refund premiums it received for sales above WECC's soft price cap of $1,000/MWh during the severe Western heat wave of August 2020.

Sen. Ed Markey has set his sights on ISO-NE, accusing the grid operator of being part of an "oil and gas conspiracy."

ISO-NE requested that FERC dismiss a complaint by renewable energy groups alleging that its rules don’t adequately take into account the uncertainty of gas.

SPP says its Markets+ day-ahead offering in the Western Interconnection is on track to be completed by the end of the year.

SPP said it plans to close its Western Energy Imbalance Service, with members joining either its proposed Markets+ program or its Western RTO.

The decades-long move to competitive wholesale and retail electric markets still stirs controversy, but the benefits sway attitudes, former regulators say.
