== History ==
=== Lounais-Suomen Sähkö === The name Caruna comes from the municipality of Karuna, where Lounais-Suomen Sähkö (originally named Karunan—Sauvon Sähköosakeyhtiö) was founded in 1912.<ref>{{Cite web |title=Caruna yrityksenä {{!}} Caruna |url=http://www.caruna.fi/caruna/caruna-yrityksena |archive-url=https://web.archive.org/web/20180111212336/http://www.caruna.fi/caruna/caruna-yrityksena |archive-date=2018-01-11 |access-date=2025-09-10 |website=www.caruna.fi}}</ref> The company's founders were local manor owners Eliel Blomqvist, Otto Rotkirch, Wäinö Sovelius, Gustaf Schauman, Johan Oskar Sjöstedt, J. Peurakoski, and merchant A. Karlsson, who established the electricity company for their own needs.<ref>{{Cite news |last= |first= |date=1923-01-01 |title=Lounais-Suomen Sähkö-osakeyhtiö |url=https://digi.kansalliskirjasto.fi/aikakausi/binding/972130?page=45 |access-date=2025-09-10 |work=Maaseudun sähköistys |pages=45 |issue=2}}</ref>
The first major project was the harnessing of three rapids on the Paimionjoki river.<ref name=":2">{{Cite news |last=Riihonen |first=Risto |date=1995-10-10 |title=Kovakuntoinen Länsivoima jatkaa valloitusretkeään |work=Kauppalehti |pages=6}}</ref>
After the 1960s, more than 15 local electricity utilities were merged into Lounais-Suomen Sähkö.
=== Länsivoima === In 1995, the company's operations had expanded beyond its original area, and its name was changed to Länsivoima. Later, the company became an active player in the electricity market and became known for acquiring other electricity companies. Ultimately, however, Länsivoima was itself acquired. Imatran Voima first bought a third of it and gradually acquired a majority stake in the company.<ref name=":2" />
=== Fortum Sähkönsiirto === Länsivoima ceased to exist as an independent company in 2000 when it was merged into its parent company, which had become Fortum.<ref>{{Cite web |last=Virta |first=Ismo |date=2000-03-02 |title=Länsivoima fuusioituu |url=https://www.is.fi/taloussanomat/art-2000001320085.html |access-date=2025-09-10 |website=Ilta-Sanomat |language=fi}}</ref> It operated as Fortum's electricity distribution unit for just under 15 years.
=== Caruna === Caruna began as an independent company when Fortum divested its Finnish electricity distribution business in 2014. The current owners are domestic and international pension investors, with ownership stakes as follows: KKR (40%), Ontario Teachers' Pension Plan (40%), the Swedish pension insurance company AMF (12.5%), and Elo (7.5%).<ref>{{Cite web |date=2021-03-03 |title=AMF, Ontario Teachers’ Pension Plan Board ja KKR Carunan uusiksi omistajiksi, työeläkeyhtiö Elo jatkaa yhtiön omistajana {{!}} Caruna.fi |url=https://caruna.fi/ajankohtaista/amf-ontario-teachers-pension-plan-board-ja-kkr-carunan-uusiksi-omistajiksi |access-date=2025-09-10 |website=caruna.fi |language=fi}}</ref>
== Organization == Caruna includes two separate network companies. Caruna Espoo Oy operates in urban areas with a high cabling rate and a high number of customers to share the expenses per metres of network. Caruna Oy operates mainly in rural, sparsely populated, areas where their amount of network to be maintained, built and repaired is high. The length of the network is 168 metres per customer in Caruna Oy's area. In Caruna Espoo Oy's area, the corresponding number is 36 metres per customer.<ref name=":1">{{Cite web|title=Caruna in brief|url=https://www.caruna.fi/en/about-us/caruna/caruna-in-brief|website=Caruna.fi|language=en|access-date=2020-05-08}}</ref>
Caruna was founded in 2014, but its story really began in 1912 in a place called Karuna where a new electricity company started out. Caruna has approximately 300 employees and 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.<ref name=":1" />
Caruna is owned by Finnish employment pension companies Elo (7.5%), as well as international infrastructure investors KKR (40%), OTPP (40%) and AMF (12,5%).<ref name=":1" />
== Electricity network == The length of electricity network in total is {{convert|87,370|km}}.<ref>{{Cite web|title=Financial Statements 2019|url=https://images.caruna.fi/caruna_group_financial_statements_2019.pdf|last=|first=|date=|website=Caruna.fi|url-status=live|archive-url=https://web.archive.org/web/20201205182342/https://images.caruna.fi/caruna_group_financial_statements_2019.pdf |archive-date=2020-12-05 |access-date=}}</ref>
In 2019, a total of {{convert|3,800|km}} of electricity network was placed underground, where it is protected from the fluctuating weather conditions. The cabling rate is 56 per cent of the network. In 2019, the company distributed electricity to its customers with a reliability rate of 99.99 per cent. The newest substation is in Suurpelto, Espoo and it takes care of the electricity supply for the 20,00 customers in the area.<ref name=":0" />
Between 2012 and 2017, Caruna invested nearly €1.2 billion in building a weatherproof electricity grid. In 2017, the company's investments were €277 million. With this investment amount, Caruna was the 14th largest investor in Finland in 2017 and ranked 3rd when comparing investments to the company's revenue.{{Citation needed|date=September 2025}} Extensive investments, particularly in underground cabling, better protect the electricity grid from storms and snow loads. Additionally, power outages affecting customers are minimized.
Electricity grid companies are under pressure to raise distribution prices as the weather-proofing of the grids is brought up to the level required by the Electricity Market Act by the end of 2028.<ref>{{Cite web |title=Caruna väläyttää korotuksia sähkön jakeluhintoihin – "Meneillään poikkeuksellinen vaihe" |url=https://www.mtvuutiset.fi/artikkeli/caruna-valayttaa-korotuksia-sahkon-jakeluhintoihin-meneillaan-poikkeuksellinen-vaihe/7331026 |access-date=2025-09-11 |website=mtvuutiset.fi |language=fi}}</ref>
In 2022, Caruna's electricity distribution customers had the opportunity to comment on the company's electricity grid development plans. Over 4,000 of the company's customers provided feedback on the plans.{{Citation needed|date=September 2025}}
== Turnover == In 2022 the net sales amounted to EUR 484 million. Caruna paid a total of EUR 6.3 million in corporation tax in 2022. Caruna invested 127 million on building a reliable, weatherproof electricity network.<ref name=":0" />
In 2017 Caruna turnover was €145 million and state tax rate 4% (€6 million). In 2017 Caruna paid its stakeholders 8.17% interest (77 million) while market loans were 1.5–3 % interest.<ref name="finnwatch_2018-10-26">[https://finnwatch.org/fi/uutiset/581-hallitus-antaa-carunan-verovaelttelyn-jatkua Hallitus antaa Carunan verovälttelyn jatkua] Finnwatch 26/10/2018</ref> Company interest cost were reduced from the taxable income based on Sipilä Cabinet taxation rules.
== Criticism of tax planning == According to the civic organization Finnwatch, the Finnish state lost approximately €12 million in tax revenue in 2017 due to the company's tax planning. This was made possible by a loophole in Finland's tax legislation, which allows for lower taxes by using another company within the same group, operating in a lower-tax country, as a lender to the company in the higher-tax country. The method is based on a balance sheet exemption rule, which allows the company to deduct interest expenses in its taxation. Finnwatch criticized the Finnish government for not preventing the aforementioned practice through legislation, even though it would be technically possible.<ref>{{Cite web |date=2018-10-26 |title=Finnwatch: Hallitus antaa verokikkailun jatkua – sähköyhtiö Caruna hyödyntää porsaanreikää laissa |url=https://yle.fi/a/3-10476437 |access-date=2025-09-11 |website=Yle Uutiset |language=fi}}</ref>
