Potential for microgeneration : study and analysis

The Energy Saving Trust, in conjunction with Element Energy Limited, E-Connect and Cambridge University Faculty of Economics, has been commissioned by the DTI to study the UK potential for microgeneration technologies. The technologies included in this study are:–solar photovoltaics (PV);–wind turbines;–small hydro;–active solar water heating *;•Microgeneration is defined as any technology, connected to the distribution network (if electric) and with a capacity below 50-100kW. Most domestic installations will be below 3kWe, though thermal systems could be larger.•Microgeneration could deliver significant efficiency and CO2benefits, through increased use of renewables, utilisation of “waste”heat from electricity generation or renewable heating fuels, and avoidance of losses in the electricity transmission and distribution system.•For microgeneration to have an impact on the UK electricity system, units must be installed by consumers in their millions. This will require a new highly decentralised approach to energy planning and policy. In addition a new understanding of the likely interaction between microgeneration technology and its multitude of potential end users (the general public) must be developed.
