The world's most efficient heavy-duty gas turbine

Our 9HA.02 gas turbine features a fast, 30-minute ramp-up from start command to full load, and up to 88 MW/minute ramping capability in a 1x1 configuration or 176 MW/minute in a 2x1 multi-shaft configuration. 

The 9HA.02 also offers both standby and response modes to deliver emission-compliant operation at load levels of minimum fuel consumption. This feature complements plant turndown capability of 33% of full-load output. These units are also fuel flexible, with the ability to accommodate gas and liquid fuels with wide gas variability, including high ethane (shale) gas, hydrogen-blending, low-and-medium BTU gas and liquefied natural gas.

Installing a gas turbine in your plant shouldn’t involve any unknowns. Across our HA fleet, each original turbine is put through a rigorous full-speed, full-load (FSFL) validation test at our Greenville, South Carolina facility.

This $200 million investment allows us to push the units beyond real-world conditions—running the turbines at 110% of their rated speeds at load, and replicating the harshest conditions, from the Arabian Desert to the mountains of Colorado—all to ensure that our customers have security of supply for their end users.

GE’s HA gas turbine auxiliary systems are pre-configured, factory-assembled and tested modules engineered to reduce field connections, piping, and valves.

This translates to a simpler, faster installation that requires less labor and reduces field schedule and installation quality risks while improving overall installation times—up to 25% quicker compared to GE F-class gas turbine enclosures. This modular configuration also makes it easier for technicians to perform any needed maintenance over the gas turbine’s lifecycle.

GE is the only original equipment manufacturer (OEM) that has been previously recognized by a 3^rd party for setting two world records for powering the most efficient plant in an H-class combined-cycle (CC) application: 63.08% gross CC efficiency at Chubu Electric’s Nishi Nagoya power plant in Japan (7HA, 60Hz), and 62.22% net CC efficiency at EDF’s Bouchain power plant in France (9HA, 50Hz).

In 2021, Southern Power Generation’s 1.4 GW Track 4A power plant, a natural gas-fired power plant in southern Malaysia—equipped with the first commercial GE 9HA.02 gas turbines—was recognized by POWER Magazine as their “2021 Power Plant of the Year” and by Diesel & Gas Turbine WORLDWIDE as “Power Plant of the World”, a meaningful model for balancing climate awareness, energy affordability, and reliability.

In addition, GE’s HA technology was adopted at China Huadian Corp’s Juliangcheng plant to help accelerate the retirement of existing coal-fired capacity and replace it with new, highly efficient combined-cycle gas turbines—an important role that earned POWER Magazine’s “ReinventionAward”.

GE introduced H-class technology to the industry 26 years ago. Today, GE’s HA product portfolio—first introduced in 2014—was engineered to reduce carbon emissions and to help support today’s flexible power generation model. The H-class portfolio leverages GE’s advanced combustion and compressor technology along with critical advancements in material science, design and coatings for higher output and performance.

GE’s HA portfolio is the world’s fastest-growing fleet in its class with more than 129 gas turbines ordered by 50+ customers across 20 countries. Our HA technology has accumulated more than 1M operating hours (as of August 2021) at 30 customer sites globally, and 2/3rd of our HA operating fleet has 16K+ operating hours and it is ready to help tackle Vietnam's power needs.

The 9HA’s DLN 2.6e combustion system offers a step change in performance, emissions, and fuel flexibility. The DLN 2.6e maintains many of the elements of GE’s DLN 2.6+ combustion system and introduces advanced premixing for reduced NOx emissions while enabling high plant efficiency.

Its advanced premixer enables expanded fuel flexibility to operate on both “rich” and “lean” gaseous fuels, a 50% hydrogen (H2) capability with a future technology pathway to 100%, a gas turbine turndown to more than 30% load, and an optional park mode at 7-15% load, further reducing customers’ operating costs.
