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.

MISO officials answered questions about the capacity shortfalls and expensive prices in the 2022/23 auction while stakeholders asked for more supply data.

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.

Stakeholders told MISO it should use a consistent capacity accreditation process for both its conventional and non-thermal generators.

PJM MIC members last week unanimously endorsed a revised proposal from the RTO and its Independent Market Monitor to address start-up cost offer development.

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.
