How it Works


Electricity Production

Tenaska has based its plan on a 925-megawatt (MW) combined-cycle electric generating facility, although the plant could be smaller. At 925 MW, the plant would produce enough power to meet the energy needs of approximately 925,000 homes. The electricity would be sold into the PJM Interconnection regional transmission organization to meet growing regional energy needs. The PJM Interconnection market assures the electric reliability of the largest centrally dispatched grid in North America, and it includes the state of Pennsylvania.

In combined-cycle facilities, energy produced by combustion of natural gas drives turbine-generator sets to produce electricity. The exhaust heat from the gas turbine-generator sets is used to produce steam, which drives a steam turbine-generator to produce more electricity without using additional fuel.
