Our history

For us, it is important to keep our origins in mind.

Ellevio's family tree stretches back all the way to the 1600s. This is when hydropower was first utilised to make work more efficient in so-called mill towns and factory towns. Uddeholms Bruk, Billeruds Bruk and Kraftaktiebolaget Gullspång-Munkfors are all part of our history in one way or another. We also have a valuable presence in Sweden's capital owing to Stockholm Energi, which started electrifying Stockholm at the end of the 19th century. And, even today, our history is markedly apparent; we have our head office in Stockholm, a bustling office in Karlstad, and employees in dozens of other towns and cities.




  • We get a new owner as the Swedish occupational pensions company AMF acquires 12.5 percent of the shares. AMF acquires its share from Första AP-fonden.
  • The business area Ellevio Energy Solutions is launched, which will help companies convert to electrified, fossil-free operations. Ellevio Energy Solutions AB, a sister company to Ellevio AB, runs the business.


  • We acquire the energy group Edbsyns Elverk, with approximately 4,000 electricity network customers.
  • We begin the rebuilding of the primary substation Värtan in Hjorthagen, Stockholm. The project is the most complex and largest station project we have ever completed and will run until 2026.
  • We receive three fine awards as employer – the award “Sweden's most attractive employer” from the Key Figures Institute, Håll Nollan's work environment award for our security work and the award as Career Company, by Karriärföretagen.


  • We acquire Hamra Besparingsskog electricity grid and get about 500 new customers.
  • We launch our largest project ever; the new cable between Beckomberga and Bredäng in Stockholm. The project is a part of our work to strengthen and modernise the electricity network to meet future electricity needs.


We launch a new model to build more charging poles for electric cars. The concept makes it easier, faster and cheaper to get new charging places.


  • We join, as the first energy company in Sweden, the construction industry's safety initiative “Håll Nollan”. The initiative has a clear goal of reducing the number of workplace accidents on construction sites, a goal that goes hand in hand with our goals and vision.
  • We sign an agreement with GodEl, who will be the default electricity supplier for our moving customers. The collaboration means, among other things, that customers are offered one of the market's best prices for eco-labelled electricity.


We buy Elverket Vallentuna, which in September 2018 give us approximately 14,500 new customers and several new colleagues.


We acquire Nynäshamn Energi, which in 2017 was integrated into Ellevio's operations.
