Connecticut Council Signs off on 485-MW Bridgeport Harbor Project

PSEG Power Connecticut's Bridgeport Harbor Station

The Connecticut Siting Council on July 21 issued a declatory ruling that no Certificate of Environmental Compatibility and Public Need is required for PSEG Power Connecticut LLC to build the gas- and oil-fired, 485-MW Bridgeport Harbor Unit 5, which would replace an existing coal unit at the site.

PSEG on March 9 applied for this ruling. The Bridgeport Harbor plant currently consists of Unit 3, a 384-MW coal facility, and Unit 4, a 17-MW peaker fired by jet fuel. The new Unit 5 would primarily use natural gas, with ultra-low-sulfur distillate as a back-up. PSEG has committed with local groups to retire Unit 3 by July 2021 if Unit 5 is approved and built.

Unit 5 would consist of one General Electric 7HA.02 gas turbine, a heat recovery steam generator and a steam turbine with total net output of 517.9 MW (winter) on gas. The 485-MW figure is used because that is what PSEG has committed to supply in ISO New England’s forward capacity market. PSEG sees this plant, under current ISO New England conditions, as load-following, which is roughly equivalent to intermediate usage. An average capacity factor of 80% is expected.
