First Class in H-Class

Our power generation experience is filled with industry firsts and impressive milestones, culminating in the 2014 introduction of the highly efficient HA gas turbine. Other OEMs have followed suit, but none can offer the outstanding performance, reliability, efficiency, and expertise of GE H-class gas turbine. Our engineers were the first to leverage new gas turbine technology and achieve 62.22% combined-cycle net efficiency (at EDF Bouchain in 2016 with a 9HA.01), and 65% efficiency is on our horizon. Advanced gas turbine materials and coating as well as evolving combustor technology are putting our H-class turbines ahead of the curve with the industry’s lowest gas turbine levelized cost of electricity (LCOE), building on our heritage of continuous improvement and innovation.

Tambak Lorok Combined Cycle Power Plant Block 3



Semarang, Central Java, Indonesia






Mid-2020 (Expected)



9HA.02 gas turbine D60 steam turbine HRSG


“The Tambak Lorok Combined Cycle Power Plant Block 3 will generate enough electricity to power the equivalent of more than five million Indonesian homes.”


Indonesia is the fourth most populated country in the world, and the densely-occupied Island of Java is home to more than 140 million people. An ever-increasing population has pushed Indonesia's power demands to new heights, forcing the islands to redefine the way power is generated, delivered, and maintained. Because of Java's land restrictions, power plants must have a small footprint and generate the most output per land surface. Energy efficiency is also key, as gas prices tend to be high in South Asia.


Indonesia Power (IP), a wholly owned subsidiary of PT Perusahan Listrik Negara (PLN), is constructing Block 3 of the Tambak Lorok Combined Cycle Power Plant in Java's north coast City of Semarang. GE's record-setting 9HA gas turbine technology will be at the heart of the new 780 MW facility, providing the flexibility and efficiency needed to complement Java's growing population. The full turnkey solution will pack a lot of punch in a small footprint and offer IP unmatched performance to drive the best economics over the plant's lifetime. ''

“When completed, this will be the largest natural gas power plant in Latin America.”


Brazil is all about affordable, reliable, clean energy solutions. In fact, 83 percent of the country's domestically produced power is being supplied by renewable sources. Renewable energy is exponentially beneficial, but even carbonconscious governments must diversify their energy mix. With large generating capacity and high efficiency as requirements, Centrais EIE!tricas de Sergipe S.A. (CELSE) is setting out to transform the way fossil fuel-fired power plants deliver electricity in Brazil.


GE is delivering a 1.5 GW, full turnkey natural gas-fired plant with digital solutions that will account for an estimated 15 percent of Northeast energy demand in Brazil. The plant will feature three of GE's world-record setting HA gas turbines and deliver efficiency greater than 62 percent. 7HA technology is flexible and will complement Brazil's intermittent renewable energy resources by delivering full power to the grid in less than 30 minutes.
