ABB Contracts for St. John Repowering

Issue 10 and Volume 103.

ABB Alstom Power has taken the turnkey contract to repower a conventional oil-burning thermal power plant unit in St. John, New Brunswick, Canada. It is believed to be Canada’s first major combined-cycle repowering project.

The contract, valued at approximately $100 million, was placed by independent power producer Bayside Power Inc.

The repowering project will increase output from 100 MW to 265 MW, while substantially increasing the unit’s thermal efficiency up to 56 percent. Commercial operation is planned for the first quarter of 2001.

The plant will supply power to New Brunswick during the winter and to the deregulated merchant power markets in the northeastern United States in the summer.

The project will keep the plant’s existing steam turbine and replace the oil-fired boiler with one of ABB’s natural gas-fired GT24 advanced gas turbines, an electrical generator and a heat recovery steam generator.
