Grid signal API
Europe’s grid signal, for compute schedulers
When power will be cleanest and cheapest over the next 48 hours, market by market, in a form a job scheduler can call. The same data runs the live grid dashboard today.
What the signal would contain
Three fields per market and hour, for the next 48 hours.
Carbon intensity
A production-based estimate per market and hour, imports excluded. Hours ahead come from the renewable-share forecast and are flagged as forecast.
Day-ahead price
Euro per MWh for the hours already auctioned, in every market covered.
Cleanest and cheapest window
For a job of a given length, the start time that minimises carbon or cost inside the next 48 hours.

Today’s numbers from the live grid feed, in the shape a call would return.

Who it is for
Teams that can move compute in time.
AI labs and platform teams
Training and batch inference queued to start when power is cleaner or cheaper.
HPC centres
A job scheduler that takes an hourly grid signal as one of its inputs.
Colocation and enterprise operators
An hourly carbon figure for their own reporting and dashboards.
