This 2005 LMOP Project of the Year was Santee Cooper's second green power generating facility. Santee Cooper was the first electric utility in the state to offer green power to its customers. Now, their customers in a three-county area, as well as three-fourths of the state's electric cooperatives, have the option to purchase green power.

Green power is offered to residential customers in blocks of 100-kilowatt-hours (kWh) each. Because it costs more to produce green power than by conventional means, a $3 premium is charged on a customer's electric bill. Commercial customers are offered green power in blocks of 200-kWh each for a $6 premium.

The project's highlights include the following:

  • Three 1.8-MW GE Jenbacher engines originally, fueled by methane, generate electricity.
  • A 5.5-MW Solar gas turbine was added in 2009, increasing capacity to 10.9 MW.
  • Lee County plant expected to grow to 12 units, producing 21.6 MW by 2010.
  • Santee Cooper expects to have 54 MW of green power on line by 2012.
