Joonas Vaaramaa, Expert, Forestry Management, travels the length and breadth of Finland when managing the condition of the grid.
The commissioning of substations and transmission lines involves several important steps to ensure safety and the functioning of the grid. In this process, seamless collaboration between Fingrid’s specialists, contractors and the main grid control centre is key.
Transporting a transformer weighing hundreds of tonnes to a substation by road requires precise planning. Before the route is clear, inspections, modelling, geometry, negotiations and often also infrastructure construction or repair are required.
Fingrid is the transmission system operator for Finnish people. Its mission is to safeguard a reliable energy supply for society and promote a clean, market-based power system.
The green transition in Finland requires investments in the main grid. Fingrid is using significant amounts of green financing to fund them.
Our country’s location, reliable grid, and abundance of renewable energy attract data centres. In turn, they can produce heat in the local district heating network and provide grid balancing services.
The Helsinki underground cable connection is the first of its kind, and at different stages of construction it has posed many challenges to solve. Despite these, the cable project has kept to its timetable.
Building new transmission lines is an important step to improve the vitality of a municipality. Right now, many more connection enquiries are made than connections can be realised. Therefore, the main grid and its connections are only built where the customers have project permits and construction can begin
Since 2010, Finland’s main grid has expanded more than ever before. The pace will accelerate further in the coming years. The Aurora Line transmission link is this decade’s most significant investment in the main grid.
Fingrid is planning reforms to restructure the main grid fees and contribute
to improving the network’s adequacy during the transition of the power
system. The new model encourages a regional balance, easing congestion in
the transmission network.
