Distributed Generation

Distributed Generation (DG) has an essential role to play in reducing emissions and improving security of supply because it can use relatively small, localised, sources of fuel (often renewable) to generate electricity, with or without heat. How much DG can be tolerated on each voltage level of a network and concerns about stability and intermittency are among the issues discussed in this stream.

Types of Distributed Generation

Submitted by David Chapman on Tue, 2008-05-13 15:50.

DG falls into two broad categories; that which uses renewable energy sources (RES) and that which increases the exploitation of traditional fuels by making proper use of the heat by-product.

DG from renewable energy sources includes the solar, wind, hydro and marine (wave and tidal) energy as well as sustainable fuels such as biomass.

Application Notes:

IET factfiles:

Combined heat and power (CHP) plants generate heat and power close to the point of use. By making full use of the heat output, high efficiency is achieved. Typically, CHP plants use biomass or gas as fuel.

Small scale or microgeneration is tailored for domestic and small commercial use.
