Between 1st October and 2nd December (9 weeks), UK electricity generation was provided by:

What does this mean?

Amidst concerns about supplies of gas for power generation this winter, the contributions of renewables and other forms of generation are reducing the amount of gas that is needed for power generation. As more renewables and other forms of electricity supply are connected to the grid, more gas will be displaced. This means that more gas is available for other purposes, for example heating.

Between 1st October and 2nd December (9 weeks)

  • Renewables have generated 20TWh of electricity. As an illustration, for gas power stations to have generated the same amount of electricity would have required 40TWh of gas. This is equivalent to the gas required to heat 4.4million homes for the entire winter, or contained within 46 tankers of LNG.

  • Other sources of generation (e.g. nuclear) have generated 11TWh of electricity. As an illustration, for gas power stations to have generated the same amount of electricity would have required 22TWh of gas. This is equivalent to the gas required to heat 2.4million homes for the entire winter, or contained within 25 tankers of LNG.
Since 1st October, renewables have generated the equivalent to the gas contained within 46 tankers of Liquid Natural Gas.

Data sources

In this analysis, renewables are primarily wind, hydro and solar, whilst other sources of generation are primarily nuclear, biomass and pumped hydro. In keeping with energy industry practice, winter is defined as the six months of October to March.
