What is carbon intensity of the UK electricity grid?

Carbon intensity measures the amount of CO₂ emitted per kilowatt-hour of electricity consumed (gCO₂/kWh). The UK grid carbon intensity varies throughout the day depending on how much renewable energy (wind, solar) is generating versus fossil fuels (gas, coal). A lower number is cleaner. UK Grid Live shows the live carbon intensity updated every 5 minutes.

How much of UK electricity comes from renewables?

The UK renewable electricity percentage changes in real time based on wind speed, sunshine, and grid demand. In 2024, renewables supplied over 50% of GB electricity on average. UK Grid Live shows the live renewable percentage including wind, solar, hydro and biomass, updated every 5 minutes from the Carbon Intensity API and Elexon.

What is the current UK wholesale electricity price?

UK wholesale electricity prices are shown in £/MWh. UK Grid Live displays the APX spot price for the current half-hour settlement period, the day average, and the system sell price (SSP) from Elexon BMRS. Octopus Agile half-hourly consumer tariff prices are also shown in p/kWh.

How often is UK Grid Live updated?

UK Grid Live refreshes every 5 minutes automatically, pulling data from the Carbon Intensity API, Elexon BMRS (Balancing Mechanism Reporting Service), Sheffield Solar PVLive, and NESO. Generation mix data is published every 30 minutes in settlement periods.

What are GB electricity interconnectors?

GB has nine electricity interconnectors linking it to France (IFA1, IFA2, ElecLink), Belgium (Nemo), Netherlands (BritNed), Norway (NSL), Denmark (Viking), Northern Ireland (Moyle) and Ireland (East-West). When importing, GB brings in electricity from Europe. UK Grid Live shows live flow direction and volume for each cable.
