DTE EAST CHINA LLC, a 358 MW Natural Gas power plant in St. Clair County, Michigan. Operated by DTE EAST CHINA LLC, commissioned 2002.
How DTE EAST CHINA LLC compares
With 358 MW of capacity, DTE EAST CHINA LLC ranks 16th among the 171 operating power plants Bywatts maps in Michigan and 8th of the 29 operating Natural Gas plants in the state. It accounts for about 3.9% of Michigan's operating Natural Gas capacity and 1.4% of all operating capacity in the state. Nationally it is the 409th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 2002, it is newer than 80% of the 168 operating Michigan plants with a recorded commissioning year. It shares St. Clair County with 6 other operating plants, including BELLE RIVER and GREENWOOD.
EIA-860 lists 4 generators at the site with 358 MW of nameplate capacity, all natural gas fired combustion turbine technology. Net generation was 770 GWh in 2024 (a 25% capacity factor), about 2.3 times its 2022 output.
Grid neighborhood
The closest transmission line found within 10 miles is a 120 kV line, under 0.1 miles away. Another 6 operating power plants totaling 1,696 MW sit within 25 miles; the largest is BELLE RIVER (1,664 MW, Coal).
