Reply to comment by sexy_wash_bucket in Any context other than it’s really cold? Peco asking for electricity conservation. by Unlucky-External5648

For the first issue, couldn't they have seen this coming and purchased more power? If I'm understanding correctly, it seems like they screwed up even though they knew the storm was coming. And now they're asking us to make sacrifices for their lack of planning.

Sort of. The day-ahead market is heavily regulated on a federal level by FEEC, so every provider is required to bid in the market for all of their capacity. PJM can’t do anything to increase bids besides wait for a new plant to be built. But they can anticipate when bids won’t cover projected capacity demand.

Although (into the nitty gritty here), there’s also smaller scale one-state plants that actually fall outside of FERC jurisdiction that can add to capacity, but PJM has less control over them and PJM also factors them into capacity projections.

PJM has the most robust capacity market in the country. It’s concerning for the future that this weekend is a problem.
