"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. Benefits of the 7HA.02 include:
- Plant flexibility: The ability of the 7HA.02 to ramp up or down at 50-MW per minute is viewed as a tremendous benefit to PSEG and ISO-NE, especially as intermittent renewable resources are added to the grid.
- Rapid response: The 7HA.02 engineered equipment package is a full rapid-response plant, able to start up and achieve emissions compliance in as little as 30 minutes while providing over 200 MW of power to the grid within 10 minutes.
- Largest, most-efficient 60 Hz gas turbine: The 7HA.02 gas turbine is the world's largest 60 Hz gas turbine and provides high power density and lower total installed costs. It also creates lower amounts of greenhouse gas emissions per megawatt hour.
