On Tuesday, Ontario Teachers’ issued a press release stating it has reached an agreement to sell stake in Caruna to Iberdrola:

London, July 21, 2026: Ontario Teachers’ Pension Plan Board (Ontario Teachers’) today announced that it has reached an agreement to sell its 40% shareholding in Caruna, as part of a broader transaction that will see Iberdrola become the new majority shareholder for the business. The transaction values Caruna at around €5 billion, including its financial debt.

It is also worth reading the press release Iberdrola issued on this deal:
- Caruna serves one and a half million people –more than 20% of Finland’s population– and has 89,000 km of electricity distribution networks
- The transaction marks Iberdrola’s entry into Finland, a market with an AA+ credit rating, attractive regulation and strong growth prospects driven by electrification
- The deal, together with the recent divestment of thermal power plants in Mexico, reinforces the Group’s strategy of focusing its investments on electricity networks
Iberdrola has reached an agreement to acquire Caruna, Finland’s leading electricity distribution company, in a transaction valuing 100% of the company at around €5 billion, including its financial debt.
The transaction will involve a payment of €2 billion for 80% of the company’s equity, while Nordic pension funds AMF and Elo will retain their current 20% stake.
Caruna is the country’s largest electricity distribution operator and serves one and a half million people –more than 20% of the Finnish population–. The company has a network of approximately 89,000 kilometres, 67% of which is underground.
Caruna operates, through two distribution concessions, in the area surrounding central Helsinki and in the Joensuu region —with strong industrial activity and growing demand linked to new data centres, as well as residential developments— and in other areas of western and north-eastern Finland.
Network growth and new opportunitiesThe acquisition, together with the recent divestment of thermal power plants in Mexico, reinforces Iberdrola’s strategy of focusing its investments on the networks business in stable markets with attractive regulatory regimes: Finland has an AA+ credit rating and a regulatory framework in place until 2031 that offers a return on equity of around 8%.
The company is expected to increase its earnings and asset base by around 7% annually over the coming years, with annual investments of between €200 million and €300 million to reinforce and digitalise its electricity network in a context of strong growth in renewable capacity1.
These investments could increase in the future due to growing demand, the electrification of the economy, the expansion of data centres and the development of electricity transmission infrastructure, which Finnish regulation has allowed distribution companies to undertake since the beginning of 2026.
Completion of the acquisition is expected in the first quarter of 2027, subject to obtaining customary regulatory approvals for this type of transaction.
Iberdrola’s executive chairman, Ignacio Galán, said: “This transaction reinforces our strategic commitment to electricity networks as essential infrastructure for promoting energy security, self-sufficiency and competitiveness. Finland offers high credit quality and a predictable and attractive regulatory framework, while Caruna has strong growth prospects due to the need for networks linked to new renewable generation, rising demand from the industrial and residential sectors and the electrification of the economy”.
I discussed OTPP's investment in Caruna, Finland’s largest electricity distribution company, back in March 2021. You can read that comment here.
Caruna is an excellent asset that was previously owned by OMERS Infrastructure prior to being sold to KKR and OTPP.
Now Iberdrola has acquired a controlling stake and KKR and OTPP couldn't have found a better strategic to acquire their 80% interest in Caruna (40% each).
Just read Iberdrola's press release and you'll understand why it acquired this asset and how it fits in its "strategic commitment to electricity networks as essential infrastructure for promoting energy security, self-sufficiency and competitiveness."
OTPP and KKR are big investors in the grid and this asset fits well in their respective portfolios.
They sold their interest, realized a gain, and will now move on to their next investment.
It demonstrates that you do not need to keep an infrastructure investment on your books forever. If the right buyer comes along, you sell it at the right price.
Below, Iberdrola has given a new boost to its strategy to grow in the electricity networks business and has reached an agreement to acquire Caruna, Finland's main electricity distribution company, in a transaction that values 100% of the company at approximately €5 billion, including its financial debt, and allows the group to enter this business in the Nordic country, the energy company reported.
The second clip shows you why this Spanish giant was the best company to acquire Caruna. Well done.
