GE's New High-Efficiency HA Gas Turbines Bound for Projects in New Jersey, Korea

GE’s new high-efficiency gas turbines will soon provide clean, reliable power for projects on opposite sides of the globe.  The 7HA.02 gas turbines are replacing aging plants in New Jersey and Korea.

Two brutal winters in the northeastern U.S. prompted PSEG Power, a subsidiary of Public Service Enterprise Group, Inc., to order the 7HA.02 gas turbine and associated equipment for New Jersey’s new Sewaren 7 combined-cycle plant.

According to GE, Sewaren 7 will feature the first dual-fuel 7HA.02 that primarily runs on natural gas but operates on ultra-low-sulfur distillate when natural gas is unavailable -- a regular occurrence during previous winters.

GE’s 7HA.02 replaces four nearly 70-year-old steam turbines. 

The facility will generate 540 MW and supply power to more than 500,000 homes.  The new plant will produce the same amount of power as the existing plant but use half the amount of fuel.

According to GE, HA technology helps lower carbon dioxide (CO2) emissions to almost half that of typical gas boilers – the equivalent of taking 150,000 cars off U.S. roads.

Furthermore, the new technology allows for faster, more-efficient startups.

Below-freezing temperatures in Anyang, Korea are responsible for GS Power’s second 7HA.02 gas turbine order.  Both are for a new combined-cycle plant in the Seoul suburb.

The Anyang project replaces an aging gas-fired cogeneration plant, and 100 percent of the steam generated by the new plant has the potential to be used for heating in winter months. 

The new facility is expected to generate 935 MW of power in combined-cycle mode, powering about 1,870,000 homes – twice the amount of power as the existing plant, according to GE, but using less fuel.

New Jersey’s and Korea’s orders represent the 18th and 19th orders for GE’s 7HA.02 gas turbines.  Additionally, HA technology has 68 technical selections for projects in the U.S., Japan, U.K., Brazil, Argentina, South Korea, France, Russia, Germany, Turkey, Egypt and Pakistan.
