Hydro Rein has taken an 80 percent stake in 25 wind projects across Sweden and Norway from IOWN Energy. Together they add up to 2.4 GW. None of them has a turbine, and only some have land agreements. The seller is not leaving, the price is not public, and the first investment decisions are not expected until the end of the decade.
Key takeaways
- Hydro Rein announced on 5 March 2024 that it had acquired an 80 percent stake in a portfolio of 25 early-stage onshore wind projects in Sweden and Norway from IOWN Energy, with IOWN keeping the remaining 20 percent.
- The Hydro Rein and IOWN Energy wind portfolio totals 2.4 GW, made up of 23 projects in Sweden and 2 in Norway, spread across the SE2, SE3, SE4 and NO2 electricity price areas.
- The value of Hydro Rein's acquisition of 80 percent of the IOWN Energy wind portfolio has not been disclosed.
- Hydro Rein and IOWN Energy expect the 2.4 GW portfolio to produce about 7.6 TWh of electricity a year, with the first investments anticipated before 2030.
- Enerdatics records 71 Nordic wind M&A transactions announced between January 2023 and December 2024, of which 20 carry a disclosed value.
What exactly has Hydro Rein bought?
It has bought a share of a development programme, not a set of power plants. Early-stage means the projects are at the start of the permitting process. Some have land agreements in place. None has been built, and none has a confirmed investment date. The companies expect the first investments before 2030.
The shape of the deal reflects that. Hydro Rein and IOWN will co-develop the projects under a long-term partnership, with ownership split 80 percent to Hydro Rein and 20 percent to IOWN. The buyer brings the balance sheet. The seller keeps the local development work and a stake in the outcome.
That fits Hydro Rein's stated focus on early-phase projects in its core markets. It is not the company's first move of this kind. In May 2023 Hydro Rein agreed to acquire two early-stage solar projects totalling 118 MW in Sweden. The IOWN portfolio is twenty times that size and in a different technology.
Why would a developer keep 20 percent rather than sell out?
Because at this stage the developer is the asset. Early-stage wind projects in Sweden and Norway still have to clear environmental permits, local consent and grid connection before anyone can price them with confidence. Each of those steps depends on relationships and local knowledge that sit with the original developer.
A retained minority stake keeps IOWN's incentives tied to the projects reaching the finish line. If the portfolio is built, IOWN shares in the value it has created. If projects stall, IOWN shares in the loss. For Hydro Rein, that alignment is worth more than owning 100 percent of a pipeline nobody is motivated to push through.
The structure also spreads risk across 25 separate bets. Some of the projects will fail to get permits. Some will shrink. A portfolio of this size gives the partners room to drop the weakest sites without derailing the programme.
How much power could the portfolio actually produce?
The companies expect about 7.6 TWh a year if the full 2.4 GW is built. That works out to a capacity factor of roughly 36 percent, meaning the turbines would produce about 36 percent of the electricity they could generate running flat out all year. That is a planning figure, not a measured one, and it assumes every project survives development at its current size.
Where that power lands matters as much as how much there is. Sweden is split into four electricity price areas, SE1 in the far north to SE4 in the south, and each settles its own wholesale price. The IOWN portfolio reaches across SE2, SE3 and SE4, plus NO2 in southern Norway. That gives the partners exposure to more than one price signal rather than a single regional bet.
Why is the price missing, and does it matter?
The deal value has not been disclosed, which is normal for early-stage pipeline transactions in the Nordics. It matters because the value of a development portfolio sits almost entirely in its probability of being built, and that is exactly what the parties have chosen not to put a number on.
What the market does show is the gap between development rights and finished assets. Among the Nordic wind deals Enerdatics records, the two priced onshore pipeline acquisitions sit far below the priced operating farms. That gap is the developer's risk, measured in money.
Enerdatics' data shows that only 20 of the 71 Nordic wind M&A transactions announced between January 2023 and December 2024 carry a disclosed value. The two priced early-stage onshore portfolios came in well under $0.1 million per MW: Fortum paid $87.14 million for Enersense's 2.6 GW Finnish portfolio in December 2024, about $0.03 million per MW, and Conquest paid $44 million for a 682 MW Finnish portfolio from Winda Energy in April 2024, about $0.06 million per MW. Operating wind farms traded at roughly 25 to 50 times those levels. Hafslund agreed to pay $333 million for the 208 MW Tonstad wind park in Norway in May 2024, about $1.60 million per MW, and Eviny agreed to pay $588.64 million for BlackRock's two Norwegian wind farms in January 2024, about $1.61 million per MW. Hydro Rein's 2.4 GW is the second largest onshore wind pipeline in that set, behind only the Fortum and Enersense portfolio.
What does the deal signal for Nordic onshore wind?
It signals that large buyers are building positions early, while pipelines are still cheap, rather than waiting to pay operating-asset prices later. Hydro Rein is a power producer with a long-term view on Nordic electricity. Taking 80 percent of 2.4 GW at the early stage lets it shape which projects get built, and when, at a fraction of the cost of buying them finished.
It also signals how slow the path from pipeline to power has become. The partners do not expect to invest before 2030, six years after signing. Over that period the projects have to navigate local consent, grid queues and whatever happens to Nordic power prices in the meantime. Deals such as BKW's purchase of 125 MW of Swedish wind from Eolus, completed with turbines already going up, show what the other end of that journey looks like.
For IOWN, the partnership brings a large partner with a balance sheet into its pipeline, while keeping a share of the upside. For Hydro Rein, the real test is not the price it paid, which no one outside the deal knows, but how many of the 25 projects reach construction.
