First class in H-class

Leading the industry in H-class technology

GE introduced H-class technology to the industry 26 years ago. Today, GE’s HA product portfolio—first introduced in 2014—is engineered to reduce carbon emissions and help support today’s flexible power generation needs. 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. 

Industry recognition

GE is the only original equipment manufacturer (OEM) that has been previously recognized by a 3rd 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 (Sultan Ibrahim 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 2020, GE Gas Power and New Fortress Energy announced that the Long Ridge power plant in Ohio will be the first purpose-built hydrogen-burning plant in the United States—and the first worldwide to blend hydrogen in a GE H-class (7HA.02) gas turbine.

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 “Reinvention Award.”

Malaysia’s Track 4 power plant (Sultan Ibrahim Power Plant) employs 9HA gas turbines

Steady economic growth in Malaysia has called for a steady increase in power capability. GE Gas Power partnered with Southern Power Generation (SPG) in the city of Pasir Gudang, Johor to meet this energy challenge for the Sultan Ibrahim Power Plant—as well as to address the country’s spreading decarbonization effort. The 9HA.02 is GE’s most advanced gas turbine in the 50-Hz range. Rated at 575 MW under ISO conditions, it pushes net efficiency beyond 64%. GE integrated two of the units into two of the plant’s single-shaft generating blocks. Now, the Sultan Ibrahim Power Plant runs on GE’s 9HA.02 combined-cycle heavy-duty gas turbines—an industry-first in commercial operation.

Stabilizing the local grid and lowering emissions for PGE

PGE ordered two GE 9HA gas turbines for its Dolna Odra power plant. When the facility goes live in 2023, its two high-efficiency/lower-emission turbines will help stabilize the regional grid—which relies on renewables—and is projected to curb CO2 emissions by an annual two to three million tons.

Responding to Taiwan’s changing power landscape

Taiwan’s government has set an ambitious goal to phase out all nuclear power sources by 2025 and increase the country’s use of natural gas to 50%. At the same time, the country is reducing its use of coal and increasing renewable resources. This rapidly changing energy mix is creating opportunities for Taiwan to diversify into fast, flexible, more efficient gas technologies that will help balance the country’s electricity grid and help meet future demand. In September 2020, GE Gas Power announced that it was selected as the successful bidder for the 6,500 MW Hsinta and Taichung combined-cycle power plants initiated by Taiwan Power Company (TPC).

Decarbonizing the future with Long Ridge Energy

With countries all over the world looking for ways to decarbonize energy and fight climate change, GE Gas Power just helped the US take an important first step. Together with New Fortress Together with New Fortress Energy, GE Gas Power announced that Long Ridge in Ohio will be the first purpose-built hydrogen-burning power plant in the United States and the first worldwide to blend hydrogen in a GE H-class gas turbine. The plant utilizes a GE 7HA.02 combustion turbine, which can burn between 15-20% hydrogen by volume in the gas stream initially, with the capability to transition to 100% hydrogen over time.

Helping to shape the Israel of tomorrow

As part of an existing plan to convert the Orot Rabin coal-fired power plant to gas generation, IEC ordered a first 9HA turbine in 2019. IEC’s focus on modernizing its plants, announced in 2018, comes as a result of a law passed by the Government of Israel’s Clean Air Law 2011. In the latest order, GE will also provide a steam turbine, generator, heat recovery steam generator and balance of plant equipment—as well as a 15-year multi-year services agreement.
