See your greenest windows — before you talk to us.

We have provided a slimmed down and stripped back version of our modelling tool for you to see the type of insights you can expect to see.

Enter a sample job manually or paste a list and the modeller finds the lowest-carbon 48-hour windows on the GB grid, using live National Grid ESO forecast data. Everything runs in your browser — your job list never leaves your machine.

With no locations collected, the baseline is the GB national forecast for each job's current slot. Three sample regions (South Scotland, London, Manchester) illustrate the regional spread. The full GridIQ app compares all 14 GB grid regions and maps results against your specific data centre locations.
