Frequently Asked Questions

What data is available?

Data includes half-hourly Electricity Generation, Carbon Intensity & Demand for Great Britain:

  • Power Plant generation and demand data for 300+ wind farms, power stations and BESS facilities
  • Live (real-time) & recent data (today / two-day / 24h / 48h)
  • Historical dashboard data: back to 2009, with options to select specific date ranges and data intervals
  • Forecast data for the day ahead
  • Generation data (breakdown by mix & type), including embedded wind & solar, and imports breakdown
  • Carbon Intensity with Index (high, low etc for National & Regional), CO2 emissions & source breakdown
  • Demand data with actual net and gross figures (allowing for embedded data) & exports breakdown
  • Data available as REST API JSON data or CSV download
What can I use the API for?

The data has a wide range of potential uses including:

  • Creating your own visualisations for electricity use and carbon intensity, on websites and other applications, to increase sustainability engagement with your users
  • As part of load and consumption shifting strategies, so that electricity is consumed during times when carbon intensity is forecast to be low
  • Sustainability tools and strategies to support a path to net zero
  • Within apps and devices used for smart home, smart building and charging technologies
What is an API?
  • • An API (Application Programming Interface) is a piece of technology which allows two different systems to talk to each other. In this case, the data used on this website has been made available to other users via a computer-friendly format called JSON, which is a data format other systems or applications can easliy utilise.
  • • The data is available through 'endpoints' which are specific URLs which accept requests and send back defined responses e.g. https://api.energydashboard.co.uk/generation/today
  • • In addition the data is also available via a manual CSV download which can be viewed in a spreadsheet program e.g. MS Excel.
  • • An API key is required to access the data and this is provided once a subscription has been started.
Is there any API documentation?

An API documentation site will be coming soon. In the meantime, information on authentication, data responses and query parameters is available by clicking on a subscription option, and then clicking on a specific endpoint.

New Feature Alert!

We've launched a UK Power Sites section where you can access data for over 3,000 power stations, wind farms, solar parks and other operational sites. Many now have dedicated pages with live generation data, interactive maps, and photos — helping you understand how individual assets behave and how they contribute to the wider electricity system.

Explore sites like Drax Biomass, the UK's largest offshore wind farm, the largest solar park, or even the iconic Electric Mountain.

You can view the full sites directory here.

2025 Year in Review

Did you know solar electricity generation was up 32% in 2025 and at times provided over 40% of GB's electricity? Or that renewables excluding biomass reached a new high of 37.3% of total generation? Yet gas usage also increased and still supplied more than a quarter of electricity throughout the year.

Our comprehensive 2025 Electricity Review reveals these key insights — including why carbon intensity rose slightly despite record renewable output, how demand grew for a second consecutive year, and which records were broken throughout 2025. Explore interactive charts, monthly comparisons with 2024, and analysis of the year's trends.
