A reliable electricity network supports the energy transition and the electrification of industry<\/h2>\n

The rapid <\/span>electrification<\/span><\/a> of society and the green transition require the expansion of the electricity grid and transmission capacity in Finland, the Nordic countries and Europe. Equally important is the renovation and maintenance of the existing electricity grid, which improves energy resilience.<\/span><\/p>\n

The transfer of overhead lines to underground cables increases the operational reliability of the electricity network and protects critical electrical infrastructure. A strong electricity network is an important attraction factor for residents, businesses and energy-intensive industries.<\/span><\/p>\n
