Bridgeport Harbor Station 5

An efficient combined-cycle plant

PSEG Power Connecticut, a division of PSEG Power, was approved by the ISO-New England Forward Capacity Auction to build a new gas-fired combined-cycle power plant in Bridgeport, CT. Construction of the new site began in June 2017. The new plant, which represents an investment of more than $550 million, is targeted to be completed and supplying needed energy to the Connecticut region beginning June 2019.

The project will add approximately 485 megawatts (MWs) of highly efficient generating capacity to Connecticut’s southwestern region to ensure electric system reliability. The new station will run primarily on natural gas, but also can run on ultra-low sulfur distillate (ULSD) as a back-up fuel, ensuring exceptional dependability. The new unit will help meet the region’s growing demand for electricity and provide a reliable alternative to older, less-efficient generation in the region.

By repowering an existing generating site, PSEG Power Connecticut is able to take advantage of existing infrastructure, replacing older, less-efficient generating units with cleaner, more efficient technology.

Bridgeport Harbor Station 5 Q&A

WHY BUILD A NEW PLANT?

Market signals indicate that new capacity is needed in the region to ensure electric system reliability. PSEG Power Connecticut bid the new plant into the recently held Forward Capacity Auction. The project cleared in the auction, which demonstrates that there is a market need for the unit. Clearing in the auction also ensures that PSEG will receive capacity revenue to support its investment. The Forward Capacity Auction is used by the electric system operator, ISO-New England, to procure the power supply needed to meet energy demand three years into the future, thus ensuring reliability of the system.

HOW WILL THE CONSTRUCTION OF A NEW COMBINED CYCLE PLANT IMPACT THE COAL PLANT?

The new plant will replace the coal plant, which PSEG Power Connecticut has agreed to finalize plans to retire after more than 50 years of providing energy to Connecticut. PSEG has entered into a Community Environmental Benefits Agreement (CEBA) with the City of Bridgeport and certain community and environmental groups. As part of the CEBA, PSEG has agreed to finalize plans to retire the coal plant, contingent upon the new plant receiving final key permits. PSEG is excited to be repowering the Bridgeport site with cleaner, more efficient technology.

WHEN WILL CONSTRUCTION BEGIN, AND WHEN IS THE PLANT EXPECTED TO COME ON LINE?

Construction of the plant will begin in the spring of 2017, and the plant will begin operations in June of 2019.

HOW MUCH POWER WILL THE PLANT GENERATE?

The new plant will bring approximately 485 MWs of electric generation to Connecticut and the region.

WHAT IS A COMBINED CYCLE PLANT, AND WHAT TYPE OF EQUIPMENT DOES IT USE TO GENERATE ELECTRICITY?

A combined-cycle power plant uses both a gas and a steam turbine together to produce more electricity from the same fuel. The plant includes a combustion turbine (similar to a very large jet engine), a heat recovery steam generator (HRSG), and a steam turbine to generate electricity. The combustion turbine uses natural gas or ultra-low sulfur distillate (ULSD) fuel oil to generate electricity. Waste heat from the combustion turbine is then routed through the HRSG to create steam, which powers the steam turbine, generating extra power. Using the waste heat from the combustion turbine to generate even more electricity makes a combined-cycle plant very efficient.

WHAT TYPE OF FUEL WOULD BE USED TO RUN THE PLANT?

The plant primarily will run on natural gas, but also can run on ULSD as a back-up fuel, ensuring fuel diversity and dependability.
