- Agentic UX
- Multiple providers per zone, switchable per request
Integrating scattered power system data across the energy sector
47 European transmission system operators, power exchanges, market and settlement operators, mapped to one model.
What is in the Grid API
Series on countries, price zones and borders, by category, with one example series for each subcategory.
Every value with two time dimensions
When it is valid and when it was published. The Grid API keeps both dimensions, so any moment can be reconstructed exactly as it was known.
Every forecast issue
Most TSOs publish their forecasts several times a day, but their data portals only keep the latest issue. The Grid API collects every issue in real time as it is published, and keeps them all.
Built for AI agents
Give your agent an API key and ask for the data in plain words. It walks the entity tree from the synchronous area down to a zone and its plants, and finds the series it needs on its own. A new dataset is minutes away, without reading the docs.

Blazingly fast with up to 30X speedup against ENTSO-E
Built for speed and scalability from the ground up. Query large time ranges, multiple areas, and years of historical data without stitching together hundreds of slow requests to upstream APIs.
Time to fetch electricity consumption data
Every request as a dot, the median marked.
We benchmarked the Grid API against ENTSO-E and the native APIs of Energinet, Elering, Fingrid and RTE. Each API was used to fetch the same electricity consumption data over 7-day, 60-day and 1-year periods across five European bidding zones.
The Grid API stays fast as the requested time range grows — reaching 30× faster than ENTSO-E and 6.4× faster than native TSO APIs for a full year of data.
For energy professionals, by energy professionals
Built for operational energy workflows, from trading and optimisation to forecasting, asset operations and system planning.
Power trading and backtesting
Backtest strategies on years of prices, production and cross-border flows, then run them live on the same endpoints. Point-in-time history means a backtest only sees what was known at the time.
Benefits
- Prices, production, load and exchange for European bidding zones through one API
- Point-in-time history: reconstruct exactly what was known when
- The same request in a backtest and in production
- A full year of data in one call, in well under a second
