Distributed generation (DG) is an approach that employs small-scale technologies to produce electricity close to the end users of power. DGs are small-scale generators which may yield power in a maximum capacity of 25mw. Below are some DG types:

• Small-scale generators(SSG)

Internal combustion engines (ICE) are the most typical and most economical type of small-scale generators. These generators are of gas-fuel type and with regard to advances in related technology, they offer a high degree of efficiency and longevity. Moreover, they need a smaller place for installation and also a shorter time to be utilized.

• Combined Heat & Power(CHP) & Combined Cooling, Heat & Power (CCHP)

A strategy now used worldwide by energy-related policy makers as an effective tool in energy management is energy production based on a simultaneous production of cooling, power and heat (or cogeneration).

As a particular type of distributed generation, cogeneration may be defined as a simultaneous production of two or more energy forms (e.g. electricity, heat or cooling) from an initial simple source ( e.g. the chemical energy from different fuels).
