How this service works
Great Britain electricity carbon intensity (gCO2/kWh) now, nationally or for a postcode region, with the generation mix (wind, gas, nuclear, solar, imports) and a half-hourly forecast up to 48h including the lowest-carbon slot. Use to schedule EV charging, heat pumps or compute jobs.
Output
Returns current carbon intensity in gCO2/kWh (national or regional), the live generation mix breakdown (wind, gas, nuclear, solar, imports as percentages), a half-hourly carbon intensity forecast for up to 48 hours, and the identified lowest-carbon time slot within that window.
Example use cases
EV charging schedule optimisation
“I want to charge my electric car overnight — can you check the carbon intensity forecast for the next 12 hours for the M1 postcode area and tell me the cleanest time slot to plug in?”
Heat pump green energy timing
“What's the carbon intensity forecast for the EH postcode area over the next 48 hours, and when is the lowest-carbon window I should run my heat pump?”
Data centre workload carbon scheduling
“What is the current UK grid carbon intensity nationally, including the generation mix, and what's the forecast for the next 6 hours so I can decide when to kick off our batch compute jobs?”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/power/uk-carbon?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time or forecast UK grid carbon intensity data to schedule flexible electricity loads (EV charging, heat pumps, batch compute) or to report on the live generation mix. It is specifically scoped to Great Britain and supports regional granularity by postcode, making it more useful than generic energy APIs for UK sustainability scheduling use cases.
Side effects
- Invalid postcode returns an error or falls back to national data
- hours parameter outside 1-48 range returns validation error
- Upstream National Grid ESO API outage causes data unavailability
- Render cold-start latency on first request after idle period
