A thermal generating station, Trenton was opened on the bank of the East River of Trenton by then-provincial Crown corporation in 1969. It was designed to burn coal mined nearby in Pictou County, Nova Scotia as well as on Cape Breton Island.

The plant burns coal and features two boilers and two chimneys; one 152 m (500 ft) and one 92 m (300 ft).[1].

The plant consumes 0.8 million tonnes of coal per year and currently generates approximately 12% of the province's electricity and produces roughly 10% of the province's air pollution, including hydrochloric acid, sulphuric acid, hexachlorobenzene and mercury.[2]

From its inception in 1969 until 2001, Trenton's coal was largely sourced on Cape Breton Island from the Cape Breton Development Corporation (DEVCO). Coal was transported to Trenton from Sydney, Nova Scotia by rail using Canadian National Railway and later the Cape Breton and Central Nova Scotia Railway.

During the fall-winter-spring of 1991–1992, the generating station burnt locally mined coal from the Westray Mine, located several kilometres south of the plant; the mine was permanently closed on May 9, 1992 after a disastrous methane gas explosion destroyed the mine, killing 26 workers.

Trenton GS burns coal from the nearby Stellarton Surface Coal Mine which is part of a reclamation project for land that was previously the location of an underground mine.[3]

Plant Retirement

Nova Scotia Power has stated that it is aiming to shut down the 152 MW Trenton Unit 5 generator by 2023.[4] As of February 2021, Nova Scotia Power has not presented a timeline for the closure of Trenton Unit 6.[5]
