Tools

current_intensity

Current national carbon intensity of Great Britain electricity for the live half-hour settlement period. Returns forecast + actual gCO2/kWh and an index band (very low → very high).

No parameters required.

▶ Try it
intensity_forecast

National carbon intensity (forecast + actual, gCO2/kWh) over a time window of half-hourly settlement periods. Use range="fw24h" for the 24h forecast forward from "from", range="pt24h" for the past 24h

No parameters required.

▶ Try it
generation_mix

Generation fuel mix for Great Britain — % share per fuel (gas, coal, nuclear, wind, solar, hydro, biomass, imports, other). Omit args for the current half-hour, or pass "from"/"to" ISO8601 UTC for a r

No parameters required.

▶ Try it
regional_intensity

Carbon intensity and generation mix for a specific GB region. Pass "postcode" (UK outcode, the first half of a postcode, e.g. "RG10") or "regionid" (1–17; e.g. 13 = London). Omit both for all regions

No parameters required.

▶ Try it
intensity_factors

Carbon intensity factors (gCO2/kWh) used per fuel type — e.g. Coal 937, Gas (Combined Cycle) 394, Nuclear 0, Wind 0, Solar 0. These are the constants behind the headline intensity figures.

No parameters required.
