Grid-tied Generator Sets. By far the most widely used distributed generation application today; these reciprocating internal combustion engines are a well-known technology. Typically, they perform back-up duty, but they are also used for peak-shaving. In optimum systems, the engine uses natural gas with a spark ignition to drive an electric generator. They range in size from 50 kilowatts to 5 megawatts. These engines are generally low-cost and with proper maintenance have a proven reliability. Their benefit for back-up power is their fast ramp-up.
