One of Fingrid’s duties is to connect new, high-capacity power plants to the main grid. The company has made careful preparations for the grid connection of Olkiluoto 3, one of the world’s largest power plant units. The final phase of these preparations includes the implementation of OL3 system protection, which will ensure that the power system functions reliably under all circumstances once the power plant is ready.
New ideas and businesses are created when information arising from an organisation’s activities is made openly available for others. Fingrid’s open data service has been online for three years now, and it is used by parties such as researchers, application developers and the authorities.
In the future, flexible resources, such as battery storage facilities and micronetworks, will play an important role in keeping the power system in balance as the advent of fluctuating renewable generation causes power generation to be spread across various parts and voltage levels on the network. Fingrid is closely involved in research and development projects to identify the best ways of realising the potential of flexible resources on the road towards cleaner energy.
Fingrid’s operation planning unit is constantly producing forecasts of electricity consumption, generation and transmission to support the electricity system. As more and more electricity comes from weather-dependent generation – solar and wind power – the importance of forecasts will also grow.
Finland has 1,300 megawatts of reserve power for use in the event of a disruption in electricity generation. Fingrid is responsible for ensuring the operational reliability of reserve power at all ten of its own plants and at seven leased plants. Reserve power is constantly on standby, although there are only a handful of disruptions each year, and the full power output is very rarely needed.
