Spanish energy giant Iberdrola has agreed to acquire an 80% stake in Caruna, Finland's largest electricity distribution network operator, for €2 billion, valuing the company at approximately €5 billion including debt. Nordic pension funds AMF and Elo will retain the remaining 20%. Caruna operates 89,000 km of network, mostly underground, serving 1.5 million people (over a fifth of Finland's population) in regions including central Helsinki and Joensuu. The acquisition, expected to close in Q1 2027 pending regulatory approvals, aligns with Iberdrola's strategy to invest in stable, regulated electricity networks. Finland's regulatory framework, effective until 2031, offers a regulated return on equity of about 8%. Iberdrola plans annual network investments of €200-300 million and projects 7% annual growth in earnings and asset base from this deal. The move follows Iberdrola's recent €3.41 billion sale of its Mexican thermal power plants.

About Caruna
Caruna operates as Finland's largest electricity distribution network, covering approximately 89,000 km of infrastructure, with roughly two-thirds laid underground. The company supplies electricity to 1.5 million people—more than one-fifth of Finland's population.
Caruna manages its network under two distribution concessions, supplying electricity to:
- The central Helsinki area
- The Joensuu region, which features significant industrial activity and growing demand driven by new data centres and residential projects
- Various parts of western and north-eastern Finland

The acquisition supports Iberdrola's strategy of focusing investment on electricity networks in stable markets with established regulatory regimes. In Finland, the current regulatory framework is set to remain in effect until 2031 and includes a regulated return on equity of approximately 8%.
Expected Timeline
The acquisition is expected to close in the first quarter of 2027, subject to customary regulatory approvals.
Executive Commentary
Iberdrola executive chairman Ignacio Galán stated:
"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."
Financial Outlook
Following the Caruna acquisition and the recent sale of its thermal power plants in Mexico, Iberdrola said the moves strengthen its strategy of focusing on electricity networks. The company has projected:
- Annual growth in earnings and asset base of approximately 7% related to this deal
- Planned yearly network investment of between €200 million and €300 million
