ERCOT is “much more likely” to deal with “emergency-alert type conditions” this summer given the system’s 7.4% reserve margin, CEO Bill Magness said.

Pennsylvania lawmakers must approve nuclear subsidies by May to prevent the retirement of Three Mile Island Unit 1, Exelon CEO Chris Crane said.

MISO posted draft 2019/20 Planning Resource Auction data that are virtually unchanged from last year’s early predictions.

The mothballing of a coal-fired plant has reduced ERCOT’s reserve margin of 8.1% to 7.4%, prodding the Texas PUC into ordering market changes.

ERCOT is preparing to take on the Texas heat again in 2019 with reserve margins that have shrunk even further than last summer's.

NERC warned that faster than expected coal and nuclear power plant retirements could jeopardize reliability if grid operators are not prepared.

ERCOT is repeating many of the preparations it took before last summer as it looks ahead to even tighter reserve margins in 2019.

NYISO said it will have adequate capacity on hand to meet its forecasted peak demand of 24,260 MW for the 2018/19 winter season.

ERCOT said Tuesday that it confronts a historically low 8.1% planning reserve margin next summer in the face of continued high electricity demand from oil and gas producers in West Texas and the cancellation of several generation projects.

The current ERCOT market design “will support more than sufficient reserve margins,” according to a draft report the grid operator filed with the Texas PUC.
