Coleson Cove Generating Station

The Coleson Cove Generating Station is a 978 MW Canadian electrical generating station located at 4077 King William Road in the community of Seaview on the extreme western boundary of the city of Saint John, New Brunswick.

A thermal generating station, Coleson Cove is situated on a cove of the same name, along the shore of the Bay of Fundy 16 km (9.9 mi) southwest of the mouth of the Saint John River at the city's central core.

The generating station is owned and operated by New Brunswick Power Coleson Cove Corporation (Colesonco), a wholly owned subsidiary of New Brunswick Power Generation Corporation (Genco), which is itself a wholly owned subsidiary of provincial Crown corporation NB Power.

Coleson Cove opened in 1976 and was designed to burn #6 fuel oil, also known colloquially as "bunker C". Fuel is delivered via the 20 km (12 mi) underground Lorneville Pipeline, which runs from Irving Oil's Canaport bulk oil tanker unloading station off Red Head, 4 km southeast of the city's central core, crossing to the city's west side via the Reversing Falls Railway Bridge. The #6 fuel oil is stored in two 1.5 million barrel tanks at Canaport and four 300,000 barrel tanks at Coleson Cove.

The plant features three boiler units powering three 350 MW generators for a total output of 1,050 MW, which is approximately 33% of the utility's generating capacity. To achieve this, Coleson Cove burns 5 million barrels of oil annually and discharges its exhaust through twin 183 m (600 ft) smoke stacks. In 1994, Coleson Cove was responsible for discharging 40,500 tonnes of sulphur dioxide (SO2), increasing to 61,000 tonnes of SO2 in 1999; the plant also discharged 17,100 tonnes of nitrogen oxides (NOx) that year.
