154 blackstart units — generators that are used to restart the grid after a widespread collapse — totaling 19 GW faced outages during Winter Storm Elliott, according to Lyons. Gas-fired generators accounted for 119 of those units, he said.
FERC and NERC staff found that 55% of the outages, “derates,” and failures to start were caused by freezing and fuel issues, and 41% were caused by mechanical and electrical issues, correlated to below-freezing temperatures.
“In a lot of our [regional transmission organizations], independent power producers, if the market design doesn’t support the expenditures for winterization, they’re not going to do it and they’re going to either retire or just get out of the market,” he said.
Why wasn’t the market already designed to encourage winterization? Why is so much of the electrical grid vulnerable to severe weather on both ends of the thermometer?
19GW of blackstart outages is unacceptable.
