Rurelec aims to use the most efficient and environmentally friendly power generation technologies available. This allows us to make savings in fuel efficiency whilst reducing the environmental impact of our activities, thus benefitting shareholders and local communities alike.
In particular we have had great success in implementing two combined cycle gas turbine (CCGT) projects, one in Argentina and one in Bolivia. In a CCGT, waste exhaust heat from burning gas in a gas turbine is recycled to generate more electricity. This is done by passing waste heat through a heat recovery steam generator which produces steam at a high enough pressure to drive a steam turbine. Both the gas and the steam turbines are connected to generators to produce electricity.

This greatly increases the efficiency of the plant. For example, our Comodoro Rivadavia plant in Argentina has, thanks to a conversion to CCGT, gone from 76 MW to 136 MW capacity.
