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.
ERCOT said it has sufficient capacity to meet demand for the next five years, including a forecast record peak this summer.
