Which electricity grids serve Uusimaa?
Uusimaa is served by 12 grid companies: Caruna, Kymenlaakson Sähköverkko, Caruna Espoo, Porvoon Sähköverkko, Elenia Verkko Oyj, Helen Sähköverkko, Keravan Energia, Nivos Verkot, Nurmijärven Sähköverkko, Sipoon Energia, Vantaan Energia Sähköverkot and Ekenäs Energi Ab. The municipality table shows the main grid first and the other companies serving some areas after it. A regional or municipal name alone cannot determine the company for every address. Open the local grid company's website to check its precise distribution area.
How is the grid company identified in Uusimaa?
We match the Energy Authority's distribution areas to municipality boundaries and population data. The first company listed serves the largest share of residents in that municipality. Other listed companies operate in parts of it. This is a directory for finding the relevant companies, rather than an address-level lookup or a statement about a current outage.
Can I choose my electricity grid company?
The grid company is determined by your address. You can choose the company that sells you electricity, subject to the electricity contract's terms. Check your current bill or ask the landlord which grid serves the home, then compare sellers separately. A seller's name on a bill does not necessarily identify the local distribution company.
