Delivering power around the world
Whether your power plant operates at baseload or peaking profiles, you can count on GE’s 7HA gas turbine to deliver impressive performance.
The economies of scale created by the 7HA gas turbine, combined with its 64% combined-cycle efficiency, enables the most cost-effective conversion of fuel to electricity to help power plant operators meet increasingly dynamic power demands.
The 7HA suite of gas turbines’ flexibility enables increased dispatch and ancillary revenue, while enhanced fuel flexibility accommodates a wide range of gaseous fuels (shale gas, high ethane, H2) and liquid fuels (#2 diesel, crude oils). The 7HA gas turbine ramps up to full load in 10 minutes and features a novel configuration that supports simplified installation and maintenance.
GE’s DLN family (DLN 2/2.6/2.6+/2.6e) of combustion systems enables GE’s F-Class and H-class gas turbines to reduce NOx emissions while enabling high plant efficiency plus extending outage intervals. The DLN 2.6e maintains many of the elements of GE’s DLN 2.6+ combustion system but introduces advanced premixing to the 7HA gas turbine combustor.
The GE 7HA gas turbine portfolio facilitates easier installation with 10,000 fewer labor hours compared to F-class turbines. Additionally, its modular configuration also helps streamline maintenance with quick-removal turbine roof, field-replaceable blades, and 100% borescope inspection coverage for all blades. Its simplified dual-fuel system uses less water, eliminates recirculation, and utilizes enhanced liquid purge for improved reliability and dependability.
Specifications
The 7HA combined cycle plant ramps up to full load in less than 30 minutes and features a novel configuration that supports simplified installation and maintenance. A 15% park mode enables customers to lower fuel burn and plant shutdown/startup costs during periods of low demand while providing a faster ramp to full load.

Reliable power for district heating in Korea
Planning for the future
Access to affordable, reliable and sustainable electricity is fundamental to quality of life in the modern world. To meet this growing need, Florida Power & Light (FPL) decided to install the first 7HA.03 gas turbine, the latest evolution of GE’s HA gas turbine, at its Dania Beach Clean Energy Center near Ft. Lauderdale, Florida.

Korea’s GS Power expanded its relationship with GE with an order for a second high-efficiency 7HA.02 gas turbine and associated clutched steam turbine as well as signing a long-term services agreement. The equipment will be used for a new combined-cycle power plant in Anyang, Korea, a suburb outside Seoul. The Anyang project will replace an aging gas-fired cogeneration plant, increasing GS Power’s plant efficiency and helping to meet growing energy needs.

Vice president, GS Power
PSEG Fossil, a subsidiary of PSEG Power, was seeking to retire the four existing units at its 70-year-old Sewaren Generating Station in northern New Jersey. The utility set out to commission a solution that would capitalize on lower gas prices as well as reduce power plant emissions. PSEG Fossil has replaced units 1, 2, 3, and 4 of the old Sewaren plant with a new 538-MW combined-cycle power plant—Sewaren 7—featuring GE’s 7HA.02 gas turbine. In the event of a shortfall in natural gas supply, the turbine is dual-fuel capable and can operate on ultra-low sulfur distillate (ULSD) fuel oil. Compared to the old steam generators, Sewaren 7 produces the same amount of power with the 7HA.02 turbine from half the quantity of fuel and reduces emissions by about 50%.
