Starrett City has its own power plant, the Starrett City Cogeneration Facility, located at 165 Elmira Loop on the east side of Starrett City. The power plant opened in 1973 and provides electricity, heating, cooling, and hot water to all residents of Starrett City. It is self-sufficient enough that during the 1977 New York City blackout, the complex was able to provide its own power. There is also a sewage treatment plant next to the cogeneration facility, called the 26th Ward Wastewater Treatment Plant. The treatment plant, located on a plot, can filter up to per day from the sewage systems in Brownsville, Canarsie, and East New York. The treatment plant and cogeneration facility were formerly operationally separate. However, in 1982, the city government began giving the treatment plant's methane emissions and thousands of gallons of treated cold water to the cogeneration facility, in exchange for hot water from the cogen facility.
