Exelon Generation is adding another 2,000 MW of fossil generation to its fleet in Texas, which will bring the company’s total generation in ERCOT to nearly 6,000 MW.

Although the grid demonstrated its resiliency during January’s polar vortex, more needs to be done to prepare generators for future cold spells, NERC said in a report released today.

At FERC's uplift hearing, PJM was a target for criticism from market participants smarting over the $600 million uplift bill from January’s polar vortex.

After a record-breaking winter in which it narrowly avoided load shedding, PJM says it is confident it can keep air conditioners running this summer. But forward prices suggests costs may be higher than last year.
