About Kraftdata

In English · På svenska

The project

Kraftdata is an interactive map of the Swedish electricity grid. It visualizes power plants, transmission lines, substations, electricity production, prices and outages — all sourced from publicly available open data.

The goal is simple: to make energy data easier and more entertaining to explore, so anyone curious about how Sweden's power system works can dig in without needing a data engineering background.

Who's behind it

Kraftdata is a one-person project. It is built and maintained solo, in spare time, with the aim of gathering open electricity data and presenting it in a clear, visual way.

The site is operated by Serenit AB, a Swedish company (org.nr 559539-1391) based in Stockholm.

Data sources

All data shown on Kraftdata comes from open and publicly available sources:

  • OpenStreetMap (OSM) — power infrastructure (plants, substations, lines). Licensed under ODbL.
  • Svenska Kraftnät (SVK) — Swedish transmission grid data.
  • ENTSO-E Transparency Platform — European electricity production, consumption and prices.
  • Vattenfall Eldistribution, Ellevio and Skellefteå Kraft — public power outage feeds from Swedish distribution system operators (DSOs).
  • ECMWF — weather data (wind, solar irradiance) from the European Centre for Medium-Range Weather Forecasts.
  • SCB (Statistiska centralbyrån) — Swedish administrative boundaries and statistics.
  • Global Energy Monitor — global energy infrastructure data.
  • PyPSA — Python for Power System Analysis (model components and reference data).

Models and limitations

A lot of the data shown — for example per-plant production estimates — is allocated using models, because the underlying open data is published only at higher aggregation levels (such as bidding zones).

This means two important things:

  • There is data missing in many places. Coverage of generators, lines and historical periods is incomplete.
  • The models used to allocate or estimate values are not thoroughly verified. Results should be treated as indicative, not authoritative.

Kraftdata is intended for learning, exploration and curiosity — not for operational, financial or safety-critical decisions.
