How this service works
Carbon intensity of Great Britain's electricity grid from the official NESO Carbon Intensity API (CC BY 4.0), in half-hour periods with a low/moderate/high index. No params -> current national half-hour; ?horizon=fw24h|fw48h adds the forecast; ?region=1..17 (13=London) switches to a DNO region and includes the generation mix per fuel. 30-min upstream cadence, 30-min cache.
Output
A JSON object containing the carbon intensity value in gCO2/kWh, a qualitative index (e.g. 'low'), the regional DNO name and region ID, forecast periods with from/to timestamps, and a breakdown of the electricity generation mix by source (gas, wind, solar, nuclear, etc.). Data is sourced from the UK National Energy System Operator (NESO) under CC BY 4.0.
Example use cases
Example prompt
“What's the current carbon intensity and generation mix for the London electricity grid (region 13), and can you also show me the 24-hour forecast so I know when it'll be cleanest?”
Technical details
Endpoint
GEThttps://data.greeneris.io/v1/gb/carbonWhen to prefer
Use this endpoint when you need real-time or short-term forecast UK grid carbon intensity data by DNO region, particularly for scheduling energy-intensive tasks during low-carbon periods, sustainability reporting, or building green energy dashboards. Prefer this over generic weather APIs when the specific need is electricity generation mix and CO2 intensity rather than meteorological data.
Side effects
- Invalid region ID (outside 1-17) returns an error or empty result
- Invalid horizon enum value returns a validation error
- Network or upstream NESO API outage returns a 5xx error
- No forecast data available for the requested window returns empty periods array
- Payment not completed returns HTTP 402 with a machine-readable quote
