Reciprocating Engines

The reciprocating engine is widely available today. It is the most commonly used technology for distributed generation. The technology is mature, and reciprocating engines are manufactured inexpensively in large quantities. IC engine generators for distributed power applications, commonly called gensets, are found universally in sizes from less than 5 kW to over 7 MW. Gensets are frequently used as a backup power supply in residential, commercial, and industrial applications. When used in combination with a 1-5 minute UPS (uninterruptible power supply), the system is able to supply seamless power during a utility outage. In addition, large IC engine generators may be used as base load, grid support, or peak-shaving devices.
