GE Takes Order for its Largest, Most Efficient Gas Turbines (61%)

General Electric has announced it has entered into a $500 million contract with Excelon Corp. to build four combined-cycle high efficiency HA gas gas turbines which will be the most efficient in the United States, along with two steam turbines and six generators.

A press release from Excelon states:

“The HA turbines apply advanced materials from GE aircraft engines, incorporating single-crystal alloys and thermal barrier coatings to deliver longer parts life for lower lifecycle costs. This enables the turbines to operate at higher temperatures (over 2600 degrees F), increasing efficiency and further reducing ongoing maintenance costs.”

A Reuters article says that GE claims that these turbines can convert 61 per cent of gas to electricity and combined will add about 1000 megawatts of capacity.
