DG Technologies: Microturbines, Fuel Cells, and Stirling Engines

Distributed generation (DG) promises many potential benefits, including peak shaving, price hedging, fuel switching, improved power quality and reliability, increased efficiency, and improved environmental performance. A number of technologies provide DG capabilities in sizes ranging from a few kilowatts (kW) to 10 megawatts (MW) or more. This topic covers some of the more common options: microturbines, fuel cells, and Stirling engines. We offer more in-depth information on Reciprocating Engine Generators elsewhere.
