Power Tracker

This page tracks electricity generation from different sources in winter 2022/23, showing cumulative values from 1st October.

Last updated: 30 January 2023

Between 1st October and 27th January (17 weeks), UK electricity generation was provided by:

  • Renewables have generated 38TWh of electricity.
    As an illustration, for gas power stations to have generated the same amount of electricity would have required 75TWh of gas.
    This is equivalent to the gas:
    • required to heat 8.3 million homes for the entire winter
    • contained within 87 tankers of LNG.
  • Other sources of generation (e.g. nuclear) have generated 22TWh of electricity.
    As an illustration, for gas power stations to have generated the same amount of electricity would have required 45TWh of gas.
    This is equivalent to the gas:
    • required to heat 4.9 million homes for the entire winter
    • contained within 52 tankers of LNG.

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.

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.
