Project Manager Jarmo Henttinen has taken charge of the repair work at several substations that Fingrid has overhauled in recent years, as well as the construction of new substations. The overhauls of the Imatra and Länsisalmi substations, among others, have had a substantial visible impact on nationally significant landscapes.
Fingrid currently has around 30 substation projects in progress in various parts of Finland. The construction of wind power and customers’ connection projects are the driving forces behind these investments. Fingrid’s first digital substation is under construction at Pernoonkoski in Kotka.
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.
Fingrid is working with Leppäkosken Sähkö to test a fuel cell solution that can charge the substation’s batteries, thereby safeguarding its critical functions in the event of a disturbance. Fuel cells generate energy from a mixture of water and methanol.
Fingrid is building a new substation in Inkeroinen on a plot of land rented from Stora Enso. Connection bays to serve four main grid customers will be constructed at the Tehtaanmäki substation: two for Stora Enso and the others for Kemijoki Oy and Kymenlaakson Sähköverkko Oy. “Connecting four customer grids to a single substation is […]
