A power plant with a rated capacity of 100 megawatts (MW) or more must have a Certificate of Public Convenience and Necessity (CPCN) from the Commission before plant-related construction can begin. Power plants rated less than 100 MW may require a Certificate of Authority (CA) from the Commission prior to construction. Additional information on these requirements is available here.
