Policy Integrity submitted comments to FERC in support of American Clean Power Association’s petition for a technical conference on capacity accreditation. Holding a technical conference would be appropriate because accurate accreditation is becoming increasingly difficult as grids accommodate rapidly changing resource mixes with varying energy and reliability attributes, public policy constraints, and increasing/unprecedented extreme weather events. Moreover, accreditation has become more consequential, as capacity market revenues have grown to a significant share of total market payments. We included several questions that would merit discussion at the technical conference.
