Maine Independence Station is a natural-gas combined-cycle station in Penobscot County, Maine, associated with ISO New England. The EIA plant baseline lists 550.2 MW of nameplate capacity. A FERC order describes Casco Bay Energy as owner and operator of the station and reports 490 MW of summer net capacity; FERC's asset appendix records three generating units placed in service in May 2000. The page keeps nameplate and summer-net figures distinct.
