The Frontier Generation Station is an 830-megawatt (MW), natural gas, combined-cycle electric generating station located near Shiro in Grimes County, Texas. Frontier consists of three General Electric (GE) Frame 7FA gas turbine generators, three heat recovery steam generators and one General Electric steam turbine.
At the time it was developed in the late 1990s, Frontier was one
of the largest non-utility electric generation facilities in North
America and one of the first plants able to dispatch power
to multiple grids beyond the Electric Reliability Council of
Texas (ERCOT). Electricity had previously been transmitted in
and out of ERCOT only through two expensive direct current
(DC) interties. Frontier interconnects with ERCOT through
CenterPoint Energy’s 345-kilovolt (kV) transmission line and with
grids outside of ERCOT, in the Eastern Interconnected Grid,
through Entergy’s 345-kV transmission line. Frontier’s dual grid
capability has been featured in Power Engineering magazine.
In 2001, the plant was named Project ofthe Year by Power
Engineering for the innovation. Frontier also has the ability to
generate power using fuel oil.
