GE announces record efficiency of gas turbine

GE yesterday announced that its 7HA.01 gas turbine in Chubu Electric's Nishi-Nagoya power plant in Japan achieved 63.08 percent combined-cycle gross efficiency, setting a new world record in efficiency.

The HA turbine is powering the world's most efficient power plants in both 50hz and 60hz segments, says a GE press statement.

The Nishi-Nagoya Block-1 power plant, equipped with three 7HA.01 gas turbines, is capable of generating more than 1,188 megawatts (MW) of power. That is equivalent electricity to supply approximately 2.7 million average homes in Japan.

“By providing outstanding performance, reliability and efficiency, GE's H-class gas turbines are well suited to power the upcoming high capacity LNG-based power plants in Bangladesh,” reads the statement.

“Bangladesh is exploring innovative avenues to generate electricity that is cleaner, more reliable and affordable,” said Deepesh Nanda, CEO of Gas Power Systems at GE South Asia.

“Today GE's technologies like the H-class offer one of the most cost-effective conversion of fuel to electricity as well as industry leading operational flexibility. Such attributes can be a huge value add for GE customers in Bangladesh opting to use HA gas turbines in future,” said Nanda.

GE Power partnered with Summit Power International Ltd to offer its first HA gas turbine in South Asia for Summit's upcoming 590 MW combined-cycle duel-fuel power plant at Meghnaghat in Bangladesh. GE already has an installed base of more than 35 gas turbines, generating about 2.2 GW of electricity in Bangladesh.
