About Caruna

Our company

Caruna distributes electricity and maintains, repairs and builds a weatherproof electricity network for its 680,000 customers in South, Southwest and West Finland, as well as in the city of Joensuu, the sub-region of Koillismaa and Satakunta. In order to guarantee a reliable electricity supply to its customers under all circumstances, Caruna supervises its network 24/7. A weatherproof smart electricity network also provides a well-functioning energy system for the future when digital services increase, the traffic is electrified, and the consumer becomes a producer of energy. Caruna’s electrical network is approximately 87,600 kilometres long.

Caruna Group includes two network companies - Caruna Espoo Oy and Caruna Oy

Caruna Espoo Oy operates in urban areas with a high cabling rate and a high number of customers to share the expenses per metre of network. Caruna Espoo Oy is one of Finland's most affordable electricity companies. Caruna Oy operates mainly in rural areas where there amount of network to be maintained, built and repaired is high. The length of the network is 170 metres per customer in Caruna Oy's area. In Caruna Espoo Oy's area, the corresponding number is 36 metres per customer. 

Caruna was founded in 2014, but its story really began in 1912 in a place called Karuna where a new electricity company started out. Our experience in electricity distribution spans for more than a 100 years. Above all, we strive to secure an uninterrupted electricity supply and continuously improve our electricity network. Thanks to these efforts, our customers can, for example, generate electricity for their own use and sell the surplus through our network.

Caruna has approximately 290 employees and directly contracts 1,000 additional workers across Finland. Caruna’s operations are regulated by the Finnish Energy Authority, in charge of monitoring the electricity network business in Finland.

Caruna is owned by Finnish employment pension companies Elo (7.5%) and Keva (12.5%), as well as international infrastructure investors OMERS Infrastructure (40%) and First State Investments (40%).


Caruna’s Board of Directors is responsible for the Group’s strategic development and for monitoring and steering the Group’s business operations and governance. The Board comprises representatives of Caruna’s international infrastructure investors Borealis Infrastructure and First State Investments. For more about our governance, see Annual Report 2018.
