Texans can expect larger power generation reserves at peak times over the next five years. This will reduce the likelihood of energy shortages on hot summer days. This is the conclusion of the Electric Reliability Council of Texas’ latest Capacity and Demand Report. This report outlines a substantial increase in the grid manager’s summer reserves between 2021 and 2025.
New utility-scale solar is leading the way. It will have an estimated 3,039 megawatts of new resources available by summer 2021, followed by a further 9,273 megawatts by summer 2022. Another 1,765 megawatts of wind power generation will come online for summer 2021, along with 816 megawatts of natural gas.
The growth of ERCOT’s power generation capacity will increase its planning reserve. This reserve is the difference between the expected peak demand and the total capacity of power generation connected to the grid. For 2021, ERCOT anticipates a planning reserve of 15.5 percent, rising to between 25 percent and 27 percent for the summers between 2022 and 2025.
