Energy data
Article 15 of 25 · Energy insight and dataAPIs for energy data: a guide for businesses
Direct answer
An API is a connection that lets software automatically retrieve energy data from an external source, instead of downloading figures or typing them over by hand. Think of market prices, grid data or your own consumption, arriving straight into your dashboard. The API delivers the data in a structured form, so systems can process and keep it current without human intervention.

APIs for energy data: scattered information versus Energy Intelligence
Anyone steering energy consumption or generation needs current figures: market prices, grid load, their own use. That data is spread across portals of grid operators, market parties and metering companies. Collecting it by hand every day costs time and goes wrong. An API solves this: it is a fixed, automated connection between systems. This matters to any organisation that wants to use energy data in its own dashboard, model or installation without someone having to gather figures manually each time.
- An API retrieves energy data automatically and at fixed moments, whereas manual downloading means recurring work and delay.
- There are roughly three kinds: market data (such as the ENTSO-E Transparency Platform and the TenneT data platform), metering data via your metering company or the P1 port, and weather data for generation and consumption forecasting.
- Access almost always requires registration and a key, and you are responsible for format agreements, data quality and maintenance of the connection.
Insight
Traditional approach
Information is scattered across portals, documents, invoices or separate spreadsheets.
Modern approach
Data, context and interpretation are brought together into a clear decision picture.
Decision-making
Traditional approach
Choices are made based on averages, assumptions or occasional analyses.
Modern approach
Scenarios, KPIs and current measurement data make the trade-off more concrete and repeatable.
Follow-up
Traditional approach
Actions often stay non-committal or disappear into separate reports.
Modern approach
Follow-up actions, monitoring and reporting are linked to the same energy data.
What is an API for energy data?
An API, application programming interface, is an agreed way for two systems to exchange data. With energy data this means your software sends a request to the source, for example a grid operator's data platform, and receives structured data back. This happens automatically and repeatably, often every quarter hour or every hour. The difference with manual work is large. Without an API someone downloads a file, opens it, and pastes the figures over. With an API the same data flows into your dashboard or control system without an intermediate step. The data arrives in a fixed format, so a computer can read and process it directly.
- An API is an automated connection, not a website you click through yourself.
- The data arrives structured, in a fixed format that software can read.
- Retrieval happens at fixed moments, for example every quarter hour or every hour.
- It replaces manual downloading, retyping and copying of figures.
Which kinds of energy data do you retrieve via an API?
There are roughly three categories. Market data covers prices and the grid at a national level. The ENTSO-E Transparency Platform publishes European market data and offers a web API for it with a personal access key. Grid operator TenneT makes APIs available through its own developer portal, for example for imbalance and settlement prices. Metering data covers your own connection: consumption and generation. You retrieve it via your metering company, or locally via the P1 port of the smart meter, to which you can connect your own reading module. In the Netherlands, EDSN, the grid operators' shared platform, manages the central registers behind the metering data. Weather data, finally, lets you forecast solar and wind generation or expected consumption.
- Market data: the ENTSO-E Transparency Platform and the TenneT developer portal.
- Metering data: via your metering company, or locally via the smart meter's P1 port.
- EDSN manages the central energy-data registers on behalf of the grid operators.
- Weather data: for forecasting solar and wind generation and consumption.
What does a business use it for, and what are the limits?
Businesses mainly use an API for automatic monitoring and for integration into existing dashboards. The data comes in continuously, so you follow consumption, generation and prices in one place and can build logic on it, for example an alert or a control signal. The limits show in practice. Access almost always requires registration and a key or other authentication. Each source has its own format and its own terms, so you must translate the data into your system. An API can change, go down temporarily or deliver data with delay, which means maintenance stays necessary. And data quality is not always complete: some values are provisional and are revised later.
- Automatic monitoring: consumption, generation and prices continuously in one place.
- Integration: the data feeds your dashboard, model or control system directly.
- Access requires registration and authentication, differing per source.
- Formats differ per source and the connection needs ongoing maintenance.
- Data quality can vary: some values are provisional and get revised.
