Tools & Capabilities Breakdown
Caruon Tools (5)
get_intensity
Check current UK electricity carbon intensity. Returns gCO2/kWh (forecast and actual) plus intensity level (very low to very high). Use to schedule energy-intensive tasks during low-carbon periods.
get_intensity_by_date
Get UK electricity carbon intensity for every 30-minute period on a specific date (e.g., "2024-01-15"). Returns gCO2/kWh forecast and actual. Use to identify lowest-carbon hours.
get_generation_mix
Check current UK electricity grid composition by source percentage (gas, coal, wind, solar, nuclear, hydro, biomass, imports). Use to understand real-time grid energy mix.
get_regional_intensity
Carbon intensity (forecast gCO2/kWh + index band) and generation mix for a specific Great Britain region. Pass "postcode" (UK outcode — first half of a postcode, e.g. "RG10") or "regionid" (1–17, e.g. 13 = London). Omit both for all regions at the current half-hour. Regional figures are forecast-on…
