Resource Adequacy
Resource adequacy is the ability of electric grid operators to supply enough electricity at the right locations, using current capacity and reserves, to meet demand. It is expressed as the probability of an outage due to insufficient capacity.
PJM can maintain adequate reliability with a generation fleet almost entirely composed of natural gas units, according to a study the RTO released.
