Cos Cob is a 115 MW oil-fired power plant located in the United States, operated by Connecticut Jet Power LLC. Commissioned in 1982, it utilizes oil as its primary fuel source for electricity generation. It ranks as the 56th largest oil plant in the United States. With a capacity of 115 MW, it represents 0.3% of the country's total oil capacity of 38,410 MW. The U.S. has 879 oil plants with a combined capacity of 38,410 MW. Compared to the largest oil plant, Manatee at 2,951 MW, Cos Cob is approximately 3.9% the size. Oil plays a diminishing role in the U.S. energy mix, contributing around 3% of total electricity generation. The transition towards renewable sources is ongoing, yet oil remains a backup option in some regions. Cos Cob is located in Connecticut, approximately 50 miles from New York City.

An Overview of Oil as a Power Generation Energy Source

Oil power generation involves the combustion of oil to produce electricity. The process typically begins with the extraction and refining of crude oil, which is then burned in a power plant to create steam. This steam drives turbines connected to generators, converting thermal energy into electrical energy. Oil power plants can vary in design, including steam turbine plants, gas turbine plants, and combined cycle plants, which utilize both gas and steam turbines to enhance efficiency. As of now, there are 2,416 oil power plants worldwide, distributed across 108 countries, with a total installed capacity of 286.9 gigawatts (GW).
