UK Carbon Intensity#

How clean is the UK electricity grid right now? This pack pulls from the official Carbon Intensity API (carbonintensity.org.uk) maintained by National Grid ESO. Get real-time and historical carbon intensity forecasts plus the current generation fuel mix.

Tools#

ToolPurposeget_intensityCurrent national carbon intensity — forecast gCO2/kWh, actual value, and index (very low to very high)get_intensity_by_dateCarbon intensity data for a specific date (format YYYY-MM-DD)get_generation_mixCurrent electricity generation breakdown by fuel type (wind, solar, gas, nuclear, etc.)

When this is useful#

• Smart home systems deciding when to run appliances (charge EVs when intensity is low)
• Sustainability dashboards showing real-time grid carbon data
• Research comparing UK grid decarbonization over time
• Answering "how green is UK electricity right now?"

Example#

bash

curl -s -X POST https://gateway.pipeworx.io/carbon/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"get_generation_mix","arguments":{}}}'

Returns something like:

json

{
  "from": "2024-03-15T10:00Z",
  "to": "2024-03-15T10:30Z",
  "mix": [
    { "fuel": "wind", "percentage": 38.2 },
    { "fuel": "nuclear", "percentage": 15.1 },
    { "fuel": "gas", "percentage": 22.4 },
    { "fuel": "solar", "percentage": 8.7 }
  ]
}
