Both EPA and FERC received comments on how reliability can be maintained under the former’s power plant rule that requires fossil fuel-fired units to curtail their emissions.

FERC hosted a senior EPA staffer and heard from the industry and states on how the environmental regulator's latest proposal to cut carbon emissions from  power plants will impact grid reliability as it is implemented.

FERC is hosting a review of EPA's proposed power plant rule, and the different sides of the debate got their views in early.
