Grid operator PJM juggles reforms as power auction results hit price cap again

On July 14, grid operator PJM released the results of its latest capacity market auction for the 2028-29 delivery year. Prices hit the federally approved cap of $325/megawatt-day, but the amount of procured capacity came up short of PJM's reliability requirement by 6.8 gigawatts.

In other words, prices went as high as they were allowed to go, but still did not incentivize enough generation to meet the reliability requirement that PJM wanted. Although PJM has other options to secure that capacity, the results of this latest auction underscore mounting concerns about rising prices and reliability in the region managed by the grid operator, which provides electricity for 67 million people across 13 states. And power demand from data centers is contributing to these issues.

Joining Dan Testa on this episode to talk through some of these issues is Darren Sweeney, a senior reporter at S&P Global Energy. Sweeney interviews Paul Segal, CEO of LS Power, a private independent power producer with a major presence in PJM, and Tanya Peevey, an S&P Global Energy CERA analyst for North American power and renewables.
