Iberdrola has signed an agreement with Macquarie, a global financial services group based in Australia, to sell 100% of the company that owns the electricity company's smart meters in the United Kingdom - SP Smart Meters Assets Limited, SPSMAL.

Under the terms of the deal, the company is valued at approximately £900 million (around €1.06 billion at current exchange rates). The transaction, which is subject to approval by the UK competition authority, is expected to be completed in the third quarter of 2025.

We purchased the UK distributor Electricity North West (ENW)

Iberdrola's electricity grids in the UK

The UK Competition and Markets Authority (CMA) approved in March 2025 the acquisition of an 88% shareholding in the electricity distribution network operator Electricity North West (ENW) by Iberdrola, S.A., through its subsidiary ScottishPower. 

Electricity North West (ENW) has a total company value—the 100% of the company, including debt—amounting to approximately €5 billion.

This acquisition is part of Iberdrola's strategy to strengthen its network business in countries with strong ratings, such as the UK's AA credit rating. With this acquisition, the UK becomes the company's primary market in terms of network asset base value (€14 billion), followed by the US (€13.3 billion), as at the end of the first half of 2024. 

ENW, which distributes electricity to almost five million customers in the north-west of England and has 60,000 km of electricity grids, represents a unique opportunity for Iberdrola, as it is the company that falls between ScottishPower's two distribution companies in Scotland.

Iberdrola has an 88% stake and the consortium led by Kansai –Japan's second largest electricity company and one of the largest in Asia– owns the remaining 12%. Kansai also owns 49% of Windanker and is one of the Group's strategic partners in accelerating electrification in a variety of countries.

Strategic alliance with Kansai to accelerate electrification

On 24 April 2025, we closed the deal with Japanese utility Kansai – announced in December 2024 – to co-invest in our Windanker offshore wind farm under construction in the German Baltic Sea. Kansai will acquire 49% of the Iberdrola Group will retain control with the remaining 51%.

The wind farm will have an installed capacity of 315 MW and is expected to start operations in the last quarter of 2026. The deal values the project at €1.28 billion, equivalent to €4.1 million per MW and 13.5 times the EBITDA. We will continue to manage the asset and provide construction, operation, maintenance and other corporate services.

The Windanker park will feature 21 wind turbines, each with a capacity of 15 MW, and has already sold 100% of its production through long-term contracts. This agreement strengthens our relationship with Kansai and allows us to progress with our strategy of partnerships and asset rotation, consolidating growth and financial stability in high-credit-quality markets.

In February 2025, we announced the expansion of our strategic alliance with the Japanese electric utility Kansai with the aim of accelerating electrification on a global scale. This collaboration will focus on various electrical grid and renewable-energy projects in different countries.

This new partnership is a strategic milestone that will allow us to jointly explore other investment opportunities in different technologies and regions within the renewable-energy and electrical grid industry.

On 26 April 2023, we announced our strategic alliance with GIC, one of the world's leading institutional investors, for the development of transmission grids in Brazil worth 2.4 billion Brazilian reals (€430 million). Both companies will co-invest in transmission operating assets with a total of 1,865 km of transmission lines and an annual return of BRL 430 million (around EUR 77 million), with an average concession term of 25 years.

This transaction is carried out at a multiple of 13 times EBITDA. We have also signed a framework agreement with GIC to jointly participate in future tenders for electricity transmission assets in the South American country.

Under the framework agreement, on 23 April 2025, Neoenergia sold half of its stake in the Itabapoana transmission grid to Singapore's sovereign wealth fund, GIC. The transaction is valued at 127.5 M Brazilian reais (around €19 M).

We completed our merger with Avangrid and continue to grow in the United States.

Avangrid headquarters
Avangrid headquarters in Connecticut

On 17 May, 2024, we reached an agreement with Avangrid – our US subsidiary – to acquire the remaining 18.4% of the company’s share capital. Months later, on December 23, 2024, after receiving authorisation from the Federal Regulatory Commission, the Maine state regulator and the state of New York, we successfully acquired the shares we did not already control, completing the merger with Avangrid.

Avangrid shareholders will receive $35.75 per share, and the company will no longer be listed on the New York Stock Exchange, but will remain headquartered in Connecticut.

This merger allows Iberdrola to invest more efficiently in the United States, after more than 20 years of presence in the country. The subsidiary will be able to participate in new energy infrastructure projects in its networks and renewables businesses more economically, representing a significant investment in local communities and generating hundreds of direct and indirect jobs.

Co-investment with Norges Bank Investment Management for renewable energy development in Spain and Portugal

Acuerdo Iberdrola Norges
Iberdrola's wind farm in Spain

On 17 January 2024 we announced an alliance with Norges Bank Investment Management (NBIM) to co-invest more than €2 billion in renewables on the Iberian Peninsula over three years. Both companies are adding more than 1,300 MW of additional renewables to the agreement signed in January 2023, to reach 2,600 MW of new wind and photovoltaic capacity.

We are therefore maintaining an alliance to promote decarbonisation through a portfolio of assets worth €1.2 million, of which Iberdrola will hold a majority stake of 51% and NBIM the remaining 49%, representing a direct investment of around €600 million.

NBIM, which manages Norway's sovereign wealth fund, has been one of the Iberdrola Group's main investors for years and holds on average 1.4% of all listed companies worldwide and 2.5% of listed companies in Europe, making it a benchmark fund.

On 17 January 2024, we announced an alliance with Norges Bank Investment Management (NBIM) to co-invest more than €2 billion in renewables on the Iberian Peninsula within three years. In April, the two companies sealed their exclusive agreement and reached 2,500 MW of wind and PV capacity.

On 5 April 2023, we presented The New Iberdrola Mexico – an agreement to sell 8,539 MW in Mexico for approximately $6 billion between subsidiaries of Iberdrola Mexico and Mexico Infrastructure Partners ("MIP"). The transaction has received financial support from Mexico's National Infrastructure Fund (Fonadin) and other public financial entities linked to the Mexican government.

The binding agreement to sell 55% of the business in Mexico was signed on 12 June 2023. In February 2024, after obtaining the necessary regulatory authorisations and approvals, the Iberdrola Group closed the sale of 55% of its business in the country for around $6.2 billion (around €5.8 billion). The transaction involved the transfer of 13 generation plants with an installed capacity of 8,539 MW, of which 99% corresponds to combined cycle gas and 87% to plants operating under the Independent Power Producer regime, contracted with the CFE (Federal Electricity Commission).

Through this new divestment in Mexico, which was closed in accordance with the terms agreed in June 2023, Iberdrola Group reinforces its commitment to decarbonisation objectives and reaffirms its leadership in the development of renewable energies in the country.
