Eight new pure gas-fired combined-cycle gasoline turbine (CCGT) energy crops have come on-line or will come on-line in the US this yr.
These new crops will add 7,775 megawatts (MW) of electric-generating capability to the U.S. electrical grid, based mostly on EIA’s estimates and knowledge from their newest Month-to-month Electrical Generator Stock. These eight tasks reverse 4 years of decline in CCGT plant start-ups. EIA expects CCGT electric-generating capability to succeed in nearly 290 gigawatts (GW) by year-end, or 24% of complete U.S. producing capability.
CCGT crops are one in every of 4 main sources of pure gas-fired energy era and the only largest supply of each electric-generating capability and electrical energy era. CCGT crops use each a pure gasoline and a steam turbine. Output from the U.S. CCGT fleet will probably rise from the 1,326,278 gigawatthours (GWh) it generated in 2021, which was 32% of complete electrical energy era final yr. Shares of coal-fired era (22%) ranked second, and nuclear sources (19%) ranked third by way of electric-generating capability and electrical energy era in 2021.
About half of the prevailing U.S. CCGT fleet at present working entered service between 2000 and 2006. Though annual additions of CCGT capability have risen steadily in the course of the previous 20 years, the additions this yr are about 80% under the file CCGT capability additions in 2002 and 2003.
Seven of the eight CCGT crops opening this yr are situated both within the higher Midwest or in Florida. The brand new crops are being in-built these areas to fulfill rising demand for electrical energy and to exchange retiring coal-fired energy crops.
Within the PJM Interconnection area, three new CCGT crops are opening this yr, totaling 3,918 MW of capability. These additions will assist substitute the 5,346 MW of coal-fired capability in PJM that’s retiring this yr, adopted by one other 3,774 MW of coal capability set to retire subsequent yr.
In Florida, the two,222 MW of recent CCGT capability will substitute 1,486 MW of coal-fired capability retiring this yr. In Michigan (within the MISO area), 1,403 MW of recent CCGT capability will substitute the 1,560 MW of current coal-fired producing capability that may retire this yr.
EIA expects 4,215 MW of CCGT capability can be added in 2023, when 5 new crops are slated to open. All of these services are at present below development, and we anticipate operations to start earlier than the tip of 2023.
