Cousins Island is an island in Casco Bay within the town of Yarmouth in Cumberland County, Maine, United States. It is listed as a census-designated place, with a population of 490 as of the 2010 census. The CDP is part of the Portland–South Portland–Biddeford, Maine Metropolitan Statistical Area.
The island is connected to mainland Maine by a bridge, built in 1955. It is also connected to Chebeague Island by a 15-minute ferry ride on the Chebeague Transportation Company's ferry, the Islander. The island's southwestern peninsula is the site of the Wyman Energy Center, an oil-fired electric power plant capable of producing up to 823 megawatts of electricity. Wyman is a peaking power plant, which means it is only fired up to operate during times of high electricity demand in the region, such as hot summer days. The Wyman Energy Center also includes a lithium-ion battery grid energy storage system which was the largest and the first of its kind in New England at the time of commissioning. The battery is designed to provide ISO-New England an option for handling the continual changes in electricity supply and demand.
According to the United States Census Bureau, the CDP has a total area of 2.0 square miles (5.1 km2), of which 1.0 square mile (2.7 km2) is land and 0.93 square miles (2.4 km2), or 46.51%, is water.
