What is the normally specified full reserve requirement amount?

• A. 2300 MW
• B. 2600 MW
• C. 2000 MW
• D. 1800 MW

Answer: (A)

Full reserve requirement is the fixed amount of extra generation capacity ERCOT must have available beyond the forecasted load to cover contingencies and preserve reliability. This cushion ensures the system can withstand the loss of a single large resource or other unexpected events without shedding load. In ERCOT practice, this reserve is normally set at 2,300 megawatts. That value represents the reliability margin used in planning and operating evaluations to ensure there’s enough generation to meet demand even if a major unit or transmission element trips offline, while still maintaining adequate spare capacity for other small contingencies. The other numbers would not align with ERCOT’s standard cushion for the typical peak-condition contingency, so 2,300 MW is the best match for the normally specified full reserve.
