GIC Forecast

Real-time forecast service for geomagnetically induced currents


Swedish Institute of Space Physics (IRF)
Finnish Meteorological Institute (FMI)

Technical Group

GIC & Ground Effects

SDA objective

  • monitor forecasts in real time of GIC at several different power grid stations in the south of Sweden
  • perform post-analysis to determine space weather causes of GIC
  • get an overview of the GIC forecasts on a map with the affected stations and power lines
  • get detailed information on GIC forecasts by selecting individual stations on the map.


  • Forecasts of the rate-of-change of the local geomagnetic field, the ground electrical field, and GIC
  • The models produce forecasts every 10 minutes.

Prototype GIC Forecast Service

SDA description

The goal of the project is to develop a forecast service to be used by electrical power companies to mitigate the effects of geomagnetically induced currents (GIC) caused by the space weather.Swedish power companies (Elforsk) are the users of the service and shall also take active part in the project.

The service developer is the Swedish Institute of Space Physics (IRF) in collaboration with the Finnish Meteorological Institute (FMI).

The project shall result in a software package implementing a prototype service, and a cost-benefit analysis of the service. The service shall also be coordinated with the Space Weather European Network (SWENET).
