Aim of this survey

The Office for National Statistics conducts the Quarterly Survey into Electricity Generated (EGS) on behalf of the Department for Business, Energy and Industrial Strategy (BEIS).

This survey is the most effective way of collecting the data needed to give an overall picture of electrical capacity, sales and fuel use. BEIS, as the department responsible for the energy industries, uses these data to compile comprehensive statistics on electricity supply in the UK. This ensures that the nation's needs for energy are met in the best way, taking into account competition, cost and environmental issues. The government has a policy to encourage the uptake of combined heat and power wherever it is cost effective.

There is more information on BEIS's energy statistics website and in BEIS's annual Digest of United Kingdom Energy Statistics and quarterly Energy Trends publications.

The survey is voluntary; but your co-operation in completing the questionnaire would be appreciated.
