Great Britain’s Monthly Energy Stats
Great Britain’s energy explained: September
It took a mix of energy sources to power Great Britain in September.
September's data shows how a diverse mix of technologies and fuels worked together across the energy system.
Wind generated 36.3% of Great Britain's electricity, while gas provided 20.5%. Nuclear, imports, solar, biomass, hydro, and storage also contributed to keeping electricity flowing across the country.
Gas continued to play an important role beyond electricity generation. Most gas supplies came from UK and Norwegian gas fields, while gas was used across distribution networks, power stations, exports, industry and storage.
Over the month, 22TWh of electricity flowed through the network, enough to power 22 billion washing machine cycles. Peak electricity demand occurred at 6pm on 28 September.
