Everything that shapes the grid
Live carbon intensity
See how clean or dirty the grid is right now, measured in grams of CO₂ per kWh.
Generation mix
Track where Britain's power comes from wind, solar, gas, nuclear, biomass and more.
Demand & price
Watch real-time electricity demand and wholesale market prices as they change.
Cross-border flows
Follow electricity imports and exports with France, Norway, Denmark and other neighbours.
Make the energy transition visible
The UK grid is changing faster than ever. Coal is gone, wind and solar are growing, and demand is being shaped by electric vehicles and heat pumps. Yet the data that describes this transformation is often buried in complex market systems.
Green Climate Hub brings that data into the open live generation, carbon intensity, demand, pricing and interconnector flows so policymakers, researchers, energy professionals and citizens can see what is happening in real time.
Built on authoritative data
Elexon Insights (BMRS)
Transmission-connected generation, interconnector flows and wholesale pricing.
NESO Data Portal
Estimates for embedded solar and wind on the local distribution network.
Carbon Intensity API
Real-time grams of CO₂ per kWh from NESO & the University of Oxford.
Designed for transparency
Open source
Released into the public domain so anyone can reuse, audit or improve it.
Always current
Refreshed every few minutes from official grid data feeds.
Climate first
Built to accelerate understanding of the clean energy transition.
