The GB grid, in the open.
Interrogate 782 datasets of official UK electricity-grid data in plain English, download 25 years of the solved grid a day at a time, or mount the whole parquet lake read-only. Official data; downloadable answers; validation included.
Free while in beta — just sign up and go. Built and run on finite personal resources, so please use it considerately.
A living dataset — new grid data is captured continuously; the total above extrapolates from a measured anchor and is re-trued periodically.
Five ways in, one lake.
Ask it in plain English, browse what others have asked, or mount the raw parquet yourself — every answer ships with the data and the method to verify it.
Ask the data
Plain-English questions → a read-only query runs sandboxed → a ZIP with the answer, the data, and how to verify it.
Public library
Every answered question, anonymised, with free downloads. Grab an existing answer before paying to re-run one.

25 years of the GB grid solved for every second — 800 million+ converged states. Download exactly the day you need.
Mount the lake
Read-only SFTP over the full parquet lake — download the key, mount it as a folder, and query it directly.
Data sources
The full catalogue — all 782 datasets, grouped by provider, with their coverage, cadence and columns.
