The principles for planning and developing the main grid are future customer needs, promoting the functionality of the electricity market, maintaining system security, ensuring sufficient transmission capacity, cost-effectiveness and managing an ageing network.
The grid is developed over the long term in a manner that provides technical and economic optimisation while simultaneously ensuring future operating conditions. To this end, main grid development plans are prepared and maintained in coordination with grid plans covering the Baltic Sea region and all of Europe. Planning complies with European grid dimensioning principles and design practices.
Approximately every two years, Fingrid prepares a system vision to examine various future developments in the power system. The system vision is available here.
Success in grid development is measured by analysing the adequacy of the transmission capacity, system security, project quality and costs, and monitoring performance against targets.
