Multiple MISO members appeared skeptical at their quarterly meetings that the RTO is destined to face capacity shortfalls before the turn of the decade.

NERC's Long-Term Reliability Assessment sees some risk for reliability issues in most of the country as the industry has to deal with faster demand growth and shifting supplies of generation.

PJM officials and stakeholders told FERC they oppose abandoning the RTO’s capacity market but disagree over the degree to which it needs to be changed.

EPA announced details of its Good Neighbor Plan to slash emissions of smog-forming nitrogen oxides; the rules will affect power plants in 23 states.

A new report found that nearly all coal plants studied “are more expensive to run than replacing their generation capacity with either new solar or wind.”

RTO stakeholders presented FERC with a cornucopia of suggestions for dealing with electrification and the increasing penetration of renewables.

At FERC’s annual reliability technical conference, commissioners focused on work needed to prepare the bulk power system for rapidly developing challenges.
