EIB backs Steady Energy's heat-only SMR with up to €40M convertible loan

The European Investment Bank said on September 15, 2026 that it is investing up to €40 million (about $46 million at the European Central Bank reference rate for that day) in Steady Energy, a Finnish company developing a 50 MW small modular reactor that produces heat for district heating networks rather than electricity (the 50 MW is thermal output, per World Nuclear News). The EIB calls it the bank's first investment in SMR technology. The money takes the form of a senior unsecured convertible loan, which the bank describes as quasi-equity with an option to convert into listed shares, and it is part of what the bank calls a broader financing package involving institutional, strategic and retail investors.

Those listed shares do not exist yet. A release the same day from 3North Partners Plc, a Finnish investment company formed to combine with one technology company, says 3NP and the shareholders and option holders of Steady Energy entered into a share exchange agreement on September 11, 2026 under which 3NP acquires all outstanding Steady Energy shares with new 3NP shares, plans to rename itself Steady Energy Plc, and intends to apply to list its series A shares on Nasdaq First North Growth Market Finland. That release gives the loan terms the EIB's does not: 3NP is the borrower under a finance contract for up to €40 million in two tranches of up to €30 million and up to €10 million, at zero percent interest, with a 20-year maturity unless repaid or converted earlier, Steady Energy as guarantor, and the EIB's right to convert outstanding amounts into series A shares of the combined company. The 3NP release also calls it the first financing the EIB has provided for an SMR project.

For the EIB that is a departure. World Nuclear News writes that the bank has in the past generally avoided new nuclear projects and invested only in nuclear-related safety projects, but that "in the past year or so" it has issued loans for a Romanian reactor refurbishment and for extending the Georges Besse II uranium enrichment plant in France. The EIB's own release ties the Steady Energy investment to the European Commission's strategy to bring Europe's first SMRs and advanced modular reactors online by the early 2030s, and says the operation is backed by the InvestEU programme.

Who is funding it, and how

Per the 3NP release, the main legs beside the EIB loan are these. First, irrevocable commitments, subject to certain conditions, to subscribe for new series A shares totaling approximately €69.8 million (about $80.5 million), from Elo Mutual Pension Insurance Company, Fortum Energy Holding B.V., Ilmarinen Mutual Pension Insurance Company, Mininvest Oy, Move Energy SMR Holding B.V., Orlen VC sp. z o.o., Finnish Industry Investment Ltd (Tesi), Varma Mutual Pension Insurance Company and Yes VC Select, LP. Second, an IPO aiming at gross proceeds of up to €5 million (about $5.8 million) by offering preliminarily a maximum of 500,000 new series A shares at €10 each to private individuals and entities in Finland, with one bonus share for every 15 allocated. Third, 3NP's own working capital, raised from its series B shareholders, a list that includes Pekka Lundmark, whom the release names as the combined company's board chairman from closing. The release also describes investor options for the placement investors and warrants held by the B shareholders.

The release puts the consideration for Steady Energy at 25,737,145 new series A shares, approximately 77 percent of the 33,253,478 series A shares it expects after the transactions close, with the private placement and IPO shares at approximately 23 percent. Fortum is already inside: Steady Energy's February 16, 2026 release says that at the beginning of 2026 Fortum signed an agreement on exclusive operation and maintenance services in Finland and Sweden and invested €2.1 million in the company.

The shape matches the pattern in the new-nuclear financing The Duck Curve has covered in 2026, where state instruments and long-term partners carry the risk rather than merchant revenue: the Swedish state-financing application behind Studsvik's four BWRX-300s, or the Department of Energy loan behind Duane Arnold's restart. Steady Energy's variation is to leave the electricity market out entirely. A University of Colorado Boulder preprint modeled SMR concepts selling power into US wholesale and capacity markets and found them uneconomical at advertised costs, mainly because of their operating and fuel costs; the 3NP release frames the LDR-50's competition instead as "baseload heat production technologies" and its customers as European district heating companies, primarily in Finland, Sweden, Poland and the Czech Republic. The release sets targets rather than announcing a first supply contract: its operative targets list a first TSC signed in 2027–2028, TSCs for 4–8 reactors signed in 2027–2030 and TSCs for 8–18 reactors signed in 2031–2035, where a TSC is the release's term for an agreement appointing Steady Energy as exclusive or first-priority provider of a reactor or heat-as-a-service delivery that is subject only to a final investment decision or a final heat purchase agreement before becoming fully effective.

Where the licensing stands

The EIB says the funded research and development, testing and licensing activities will be carried out in Finland between 2026 and 2028, and that Steady Energy is building a non-nuclear pilot facility in Helsinki to test key safety systems and support the licensing process with the national regulator. Steady Energy's February 16, 2026 release puts that pilot in the Salmisaari B turbine hall of a coal-fired plant in central Helsinki that Helen had decommissioned, with first concrete poured on February 12, 2026. The release describes it as a 1:1 full-scale replica of the LDR-50 with an electric resistor in place of a reactor core to simulate decay heat, and says the heat generated during testing will be supplied to Helen's district heating network.

The regulator has looked, on a non-binding basis. On June 26, 2026 Finland's Radiation and Nuclear Safety Authority (STUK) published the summary report of a Joint Early Review of the LDR-50 concept that it coordinated with the nuclear safety authorities of Ukraine, Poland, Sweden and the Czech Republic, launched in October 2025 and building on STUK's own preliminary assessment completed in June 2025. STUK says the review is not part of the licensing procedure and produces no binding decisions or joint position; that the authorities' conclusions were broadly in line with each other; that none identified fundamental obstacles in the areas examined that would prevent further development; and that in the early planning phase the concept was considered "largely appropriate, but not yet sufficient from a licensing perspective", with the actual licensing phases requiring significantly more detailed analyses.

The release's other operative targets, which it says include a pilot plant testing programme starting in 2027, a political Decision-in-Principle from the Ministry of Economic Affairs and Employment in 2027–2028 for the first commercial plant, a construction licence application in 2028–2029, and construction of the first commercial plant starting by 2029–2030, all come after that non-binding look.
