Electrical energy (Class 1710).

Alternatively, the Concise Oxford Dictionary defines electricity as a form of energy occurring in elementary particles and macroscopic bodies either statically or dynamically (The Concise Oxford Dictionary of Current English, Oxford University Press (1982), Seventh Edition (London).

Gross electricity production is measured at the terminals of all alternator sets in a station; it therefore includes the energy taken by station auxiliaries and losses in transformers that are considered integral parts of the station.

The difference between gross and net production is generally calculated as 7 per cent for conventional thermal stations, 1 per cent for hydro stations, and 6 per cent for nuclear, geothermal and solar stations. Hydro stations' production includes production from pumped storage plants (Energy Statistics of OECD Countries: 1999-2000, 2002 Edition, International Energy Agency, Paris).
