PSEG connects power plant fleet virtually with GE technology

PSEG Power, a unit of PSEG, has ordered a 7HA.02 gas turbine engineered equipment package from GE for the Bridgeport Harbor Generating Station in Bridgeport, Connecticut. This marks the second order in recent weeks for GE’s high-efficiency technology in the New England region.

The 7HA.02 package includes a gas turbine, a steam turbine, associated generators and a former Alstom-engineered heat recovery steam generator (HRSG) that is now part of the GE portfolio. The high-efficiency package will be used in an expansion of the existing Bridgeport Harbor facility and will clear the way to retire an existing coal-fired unit in operation for nearly 50 years. The unit is the last coal-fired plant in Connecticut; its retirement will help the state meet requirements expected under the federal government’s proposed Clean Power Plan.

PSEG also marked a milestone in its efforts to digitize its fleet recently, connecting five plants with plans to connect others (both GE and other original equipment manufacturers) to its state-of-the-art Monitoring & Diagnostic (M&D) Center. PSEG partnered with GE to deploy asset-performance management tools to improve predictive analytics and its ability to manage its fleet across generating capabilities.

PSEG’s power plants account for more than 6 GW of electricity and are an example of the growing trend of energy companies like PSEG leveraging the power of the Industrial Internet to increase efficiency.

“With these advanced technologies from GE, PSEG can provide cleaner, more reliable energy to Connecticut and the region for many years to come,” said Rich Lopriore, president of PSEG Fossil. “The environmental benefits of this project are essential, and we’re pleased to have received strong community support.”

At the Bridgeport Harbor facility, the existing coal-fired steam turbine has only run about 800 hours per year due to lower efficiency and higher emissions output. The new 485 MW 7HA.02-based combined-cycle power plant is expected to be one of the most efficient facilities in Connecticut, capable of running nearly 8,000 hours per year with lower emissions while providing the equivalent power needed to supply nearly 500,000 U.S. households. The new plant is scheduled to begin commercial operation in 2019.

“These projects demonstrate the value of combining GE's HA gas turbine with our complementary steam tail technologies and the power of software,” said Joe Mastrangelo, president and CEO of gas power systems, GE Power. “In Connecticut, GE's high-efficiency technologies will provide cleaner, more efficient power and help give PSEG a real advantage to getting power on the grid.”

The new 7HA.02 unit at the Bridgeport facility will run primarily on natural gas, but also will be able to operate on ultra-low-sulfur distillate as a backup fuel, an important option in the ISO-NE region where—despite an increasing supply of natural gas—long, cold winters require units that can operate on backup fuel.
