GE announced Exelon agreed to purchase four 7HA gas turbines, two D600 steam turbines, six generators and a contractual service agreement for the Wolf Hollow and Colorado Bend gas combined-cycle projects. This represents the first U.S. order for GE’s highest efficiency HA turbine, adding to recent orders in Japan, France and Russia.

The equipment is expected to ship in 2016, and the plants are due to be operational in 2017, helping Exelon provide additional capacity, competitively priced, to the expanding Texas energy grid.

“We have invested more than $1 billion in our latest H-class technology to deliver the most cost-effective, dispatchable power to consumers”, said Victor Abate, president and CEO, power generation products at GE Power & Water. “We are excited to work with Exelon on H-class power generation projects, the fastest growing segment within the gas turbine industry.”

GE’s latest HA gas turbines build off the learnings of its operating fleet of more than 4,500 air-cooled heavy-duty gas turbines with accumulated operation of more than 180 million hours and a decade of steam-cooled H-class gas turbine operating experience.
