(Recasts, updates with installed capacity details)
July 21 (Reuters) - Britain's electricity is generated from a number of different sources, including coal, gas, and nuclear.
The following shows the breakdown of power generation types in the first quarter 2009 and first quarter 2008.
Total UK electricity supply fell by 5.1 percent year on year, mainly due to lower demand in the recession, and coal overtook gas as the main fuel.
UK POWER GENERATION SOURCES FIRST QUARTER 2009
Coal 38.1 percent
Gas 37.5 percent
Nuclear 15.6 percent
Oil, renewables, and other 8.20 percent
Net imports 0.60 percent
Total supply 105,171 megawatts
UK POWER GENERATION SOURCES FIRST QUARTER 2008
Gas 45.7 percent
Coal 32.3 percent
Nuclear 12.6 percent
Oil, renewables, and other 7.10 percent
Net imports 2.30 percent
Total supply 109,915 megawatts

Total electricity generation capacity is estimated to peak at 83.6 gigawatts in 2009/10, in Great Britain, including the capacity to import from France.
Total installed capacity is:
Nuclear 10,894 megawatts
Combined Cycle Gas Turbine 28,428 MW
Combined Heat and Power 2,326 MW
Coal 28,896 MW
Open Cycle Gas Turbine 589 MW
Oil 3,636 MW
Pump Storage Hydro 2,744 MW
Hydro 1,070 MW
Wind 2,896 MW
Biopower 45 MW
Interconnector 2,068 MW
Capacity in Britain could grow by as much as 31.3 percent, or 26.6 GW, to 109.8 GW in 2015/16 if all planned power projects are built, according to National Grid.
The following indicates the energy sources for new electricity capacity if all submitted project applications are completed.
POWER INCREASE BY 2015/16 FROM 2009/10
Gas-fired power stations up 10.3 gigawatts (+12.3 percent)
Onshore wind up 5.8 gigawatts (+6.9 percent)
Offshore wind up 5.3 gigawatts (+6.3 percent)
Coal-fired power stations up 3.3 gigawatts (+4.0 percent)
Import capacity up 2.1 gigawatts (+2.5 percent)
Bio-fuel up 851 megawatts (+1.0 percent)
Hydro-power up 56 megawatts (+0.1 percent)
Nuclear down 1.45 megawatts (-1.7 percent)
