Profile

Grid role: Fast-start, flexible gas generation providing rapid response to market and grid conditions and helping counterbalance variable renewable generation.
Context: NCPA describes Lodi Energy Center as the first U.S. plant to use fast-start gas-turbine technology, enabling rapid ramping to balance variable wind and solar generation. The CEC describes the project as nominally 296 MW, while the operational EIA-derived record lists 288.9 MW.
Physical build: The Lodi Energy Center is a 1x1, nominal 296 MW natural-gas combined-cycle facility. The installed scope includes one Siemens gas turbine-generator, one Siemens condensing steam turbine-generator, one heat-recovery steam generator, one natural-gas auxiliary boiler, one seven-cell cooling tower, water-treatment and cooling systems, and associated balance-of-plant equipment. CEI reports 135 MVA for the combustion-turbine generator and 115 MVA for the steam-turbine generator; POWER identifies additional installed equipment including the Siemens T3000 control system, Nooter/Eriksen HRSG/auxiliary boiler, SPX cooling tower, and associated pumps, compressors, condenser, transformers, and water-treatment equipment.
