The utility will install the machines at sites to be determined in the Texas Panhandle or West Texas. The power stations would go on line between March 2015 to March 2017.

Power generated at the three plants will be used by GSECA’s cooperative members who operate in the Southwest Power Pool (SPP) and Electric Reliability Council of Texas (ERCOT) electric operating grids.

The latest projects follow over $1.2bn in orders GE previously announced for its FlexEfficiency 60 gas turbines, including five 7F 5-series machines for three sites in the US.

Commenting on the FlexEfficiency technology GE Power & Water’s Thermal Products division president and CEO Paul Browning said it offers "an unprecedented combination of baseload efficiency and operating flexibility".

"The 7F 5-series offers both the flexibility and the proven performance to meet Golden Spread’s wide range of power generation requirements," Browning added.

Golden Spread Electric Cooperative president and GM Mark Schwirtz commented, "We believe that the 7F 5-series gas turbine will provide a good match for our diverse electricity requirements."
