The common month-to-month capability issue for simple-cycle, pure gasoline turbine (SCGT) energy crops in the USA has grown yearly since 2020.
Common capability components surpassed 20% for 2 consecutive summer time months in 2022—the primary time on document—to fulfill peak electrical energy demand, primarily based on information from our Electrical Energy Month-to-month.
SCGT energy crops usually function year-round however are most lively in the course of the summer time when electrical energy demand reaches its peak and varies essentially the most. For the previous 5 summers, SCGT energy crops operated at a 17% common capability issue from June by August. The common month-to-month capability issue throughout the remainder of the 12 months fell to round 10% on account of much less electrical energy demand and extra constant wind-powered electrical energy era.

SCGT energy crops burn pure gasoline in a single turbine to provide electrical energy. They’re the second-largest supply of U.S. pure gas-fired energy era, after combined-cycle pure gasoline turbine (CCGT) energy crops. SCGT energy crops are much less environment friendly and require extra gas per unit of output in contrast with CCGT energy crops as a result of CCGT crops seize extra warmth from the combustion course of and ship that warmth to a steam turbine to provide extra electrical energy.
Electrical grid operators can use SCGT energy crops to reply shortly to fluctuating demand for electrical energy. The necessity for extra electrical grid assist in the course of the day is rising because the share of electrical energy era from intermittent renewables grows. SCGT energy crops can meet demand if there’s a lull in wind or photo voltaic output. SCGT energy crops can finest present grid assist as a result of they’ll produce electrical energy shortly to instantly fill gaps in electrical energy output on the grid, and so they can ramp down simply as shortly. Different pure gas-fired electrical energy mills, akin to CCGT or steam boiler crops, can take two to a few occasions longer than SCGT energy crops to start out and ramp as much as full load.
An estimated 2,121 megawatts (MW) of latest SCGT capability entered service in 2021, and we anticipate one other 1,196 MW entered service in 2022. Texas accounted for almost half of the 2021 and 2022 capability additions due to its want for extra fast-starting producing capability. Texas is experiencing each rising energy demand and larger variability in provide.
