Fingrid has developed a quick and cost-efficient solution for increasing the electricity transmission capacity between Northern and Southern Finland. The innovation, which is based on a new application of an existing technology, is a quick, cost-efficient and environmentally friendly way of adding up to 500 megawatts of additional transmission capacity to the grid.
Fingrid’s network vision analyses the need to strengthen the main grid by 2035 and 2045. The electricity transmission capacity must be boosted substantially, but in terms of the main grid, the objective of a carbon-neutral Finland by 2035 is within reach.
The urban Western Boulevard City planned by the City of Helsinki will require Helen Electricity Network’s high-voltage overhead lines and substation in the area to be moved. This will only be possible if Fingrid, the transmission system operator, brings forward its plans to build a 400-kilovolt live power feed to the city centre. Collaboration has resulted in a solution that enables third-party schedules to be coordinated optimally.
From the carbon black towards the emission-free sources, a balance must be maintained between demand and supply
Electricity generation and consumption are two sides of the same coin. People need electricity, particularly on cold winter days – but those are the days when electricity is most difficult to guarantee and supply. Coal is coming to the end of the road, so we need to look for alternatives. The answer increasingly lies in the expanding Nordic and European electricity markets.
The development of Datahub is about to be finalized and the system was opened to the entire sector for test operation in October. During the testing phase, the quality of the data will be verified, and the market parties will test various functions in phases.
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.
