Affärsvärlden Uniper Bidders and Data Centres (2026)

News article (“Brunkolsmiljardär och datacenterjättar slåss om svensk kärnkraft”, 8 October 2026) on the sale of the German group Uniper, which owns Swedish hydro and part-owns the three Swedish nuclear stations, and on why data-centre investors are among the bidders. Mostly M&A reporting with analyst comment; the grid-relevant part is the argument that existing connected generation is a shortcut around connection queues.

The sale

• Assets: Uniper is Sweden’s third largest hydropower producer, about 1.7 GW installed and about 8 TWh a year, and co-owner of Oskarshamn, Ringhals and Forsmark with about 1.4 GW of attributable nuclear capacity.
• Ownership: the German state owns just over 99 % of Uniper and plans to sell up to 74.1 %, keeping 25 % plus one share. After pressure, including from unions, it decided to keep the group together, so the Swedish assets are not sold separately.
• Bidders: the first round ended in June with about ten parties. By the indicative-bid deadline on 21 September, Fortum and Vattenfall were out; Brookfield with CPP Investment Board, KKR with RWE, Equinor, EPH (Daniel Křetínský) and, a few days before the article, Apollo remained. Fortum has a right of first offer on the Swedish hydro and nuclear assets valid to the end of 2026 and, in an email quoted by the article, says it would be interested if they became available.

Data-centre angle

• Several bidders are large data-centre investors: KKR (CyrusOne, a “Digital + Power” area), Brookfield (including Strängnäs), Apollo (Stream Data Centers) and RWE (about ten sites, over 3 GW of grid capacity applied for or secured). Uniper has a data-centre strategy and, in early 2026, a renewable-power deal for nLighten’s German sites.
• Shortcut to power: analyst Fredrik Bodecker says Uniper’s plants are long connected to the grid and sit on sites with existing energy infrastructure, valuable while new large connections take years: “a fast route to large amounts of electricity”. Arctic Securities’ Michael Johansson calls electricity and grid capacity the main bottleneck for data-centre developers, and estimates that ready-to-build Nordic land with secured grid connection is worth about SEK 5-6 million per MW before construction; he gives development at about SEK 100 million per MW and a finished value of about SEK 175 million.
• Capacity forecast (the article’s box, from EUDCA / Pb7 Research, State of European Data Centres 2026, measured as IT power, 2031 figures are forecasts): Sweden’s total data-centre capacity from 482 MW (2024) to 1,621 MW (2031); commercial data centres 157 to 944 MW, tech companies’ own 325 to 677 MW. Europe (colocation): 7,629 MW in 2024 to 23,590 MW in 2031, EUR 176 billion of investment 2026-2031, and 67 % of industry players name power and grid connection as a central obstacle.
• Regulation abroad: adviser Christian Holtz (Polite Energy) says several European countries are discussing rules to stop fast-growing data centres taking much of the limited grid capacity, and that Finland’s government is proposing a connection system that ranks data centres below other industry (the Finnish minister, Sakari Puisto, is quoted: the main aim is to “take control of the development”). Google is planning EUR 13 billion of Finnish investment in 2027-2028 and has a 22-year power purchase agreement with Fortum that underpins the lifetime extension of Finnish nuclear to 2050; Holtz suggests a buyer of Uniper’s reactors could use the same model.
• Competition for electricity: Bodecker warns that if large parts of production are tied up in long contracts with data centres, less is available to other buyers, which industry should watch. Mats Nilsson notes that the German state’s 25 % plus one share could give it a veto over investment in lifetime extensions or new nuclear.

Relevance

Context for Data Centres and Grid Flexibility: it shows data-centre capital buying existing connected generation as an alternative to queueing for new connections, and puts a Swedish figure on expected data-centre growth next to the flexibility-potential scenarios there. The Finnish ranking proposal is a policy parallel to conditional connection. It adds nothing on flexibility itself and contradicts nothing in the wiki.
