Why Byhmgard Bought a Finnish Battery Project and Took On the Remaining Development Work

Byhmgard has entered binding agreements to acquire the rights to Hitura, a 50 MW standalone battery project in Finland, from Callio-Hitura Solarpark, a subsidiary of developer Solarigo Systems. Terms were not disclosed. The project is expected to reach ready-to-build during 2026 with commissioning in late 2027. Under the agreement Byhmgard takes over the project rights and assumes responsibility for completing the development work to ready-to-build, with completion and payment staged and conditional on that milestone. It is the first acquisition under a framework agreement the two signed on 11 May 2026.

What did Byhmgard acquire, and when?

Byhmgard acquired the rights to a 50 MW standalone battery system at Hitura, moving from a letter of intent announced on 23 July to binding agreements on 26 August, roughly five weeks. Terms were not disclosed, which is universal in this market: Enerdatics records ten Finnish battery transactions at development stage during 2026 before this one, covering 809 MW, and not one carries a disclosed value. Hitura takes the year's tally to eleven deals and 859 MW, at an average of 78 MW per transaction. Energy capacity and duration were not stated, which matters in Finland because short-duration balancing and longer energy-shifting are materially different businesses.

Why is the buyer completing the development?

Because Byhmgard is not a financial buyer. The company describes itself as covering project development, EPC, software optimisation and long-term operations, so taking a project through its final development stage uses capability it already has rather than requiring it to hire any. That inverts the usual handover. In the ten other Finnish battery transactions Enerdatics has recorded this year, the developer carries the project to or near ready-to-build and an infrastructure investor buys the finished article, paying a premium for having the risk retired. Here the buyer steps in earlier, does the last leg itself, and pays in stages conditional on reaching that same milestone. The seller gets certainty of exit without funding the final push; the buyer gets a lower entry point in exchange for absorbing work.

What is a framework agreement, and why does it matter?

A framework agreement sets the commercial terms under which a series of future transactions will be executed, without committing either party to a specific asset. It removes the need to renegotiate structure, warranties and payment mechanics for each project, so subsequent deals move from agreement to signature quickly. That is visible here in the five weeks between letter of intent and binding agreements. For a developer it converts a pipeline into a repeatable route to market with one known counterparty; for a buyer it secures deal flow without competing in a process each time. In a market with eleven transactions this year and no visible pricing, a standing relationship with a single developer is a considerable advantage over bidding.

Enerdatics' data shows how fragmented the alternative looks. Across the eleven Finnish development-stage battery transactions recorded in 2026, the buyers are almost all different, with only Enlight Renewable Energy, Prime Capital and Icecreek Energy appearing twice. Sellers are equally scattered, including Korkia with Semecon, Cactos, Helios Nordic Energy, SMA Solar Technology, BHM Group, Usva Energia, Fu-Gen, Arise, and SENS with Dovre Group. Solarigo itself is a Finnish developer that has been building rather than only selling, having acquired a 17 MW operating solar project from Skarta Energy in August 2025. A framework relationship in a market this scattered is a structural answer to origination cost.

What does the deal signal for Nordic storage?

The deal signals that the entry point for Finnish storage is moving earlier for buyers who can do development work, and that repeat relationships are starting to replace one-off transactions. Byhmgard has stated a target of a 1 GW European battery portfolio with Finland and the Baltics as priority markets, and at 50 MW Hitura represents about 5 percent of that. Reaching the target through individual competitive purchases at an average 78 MW a deal would require roughly a dozen more transactions; reaching it through a framework with one or two developers is a different proposition entirely. Expect more programmatic agreements between vertically integrated buyers and Finnish developers, and expect the pure ready-to-build handover to remain the default only for buyers without development capability.

The unresolved question is revenue. Finnish storage earns from price spreads, balancing and ancillary services rather than from contracted capacity payments, so the value of a 50 MW asset commissioning in late 2027 depends on volatility persisting as more storage connects. Byhmgard's inclusion of software optimisation in its own description is relevant here, because the ability to trade the asset is what determines whether merchant Nordic storage earns its cost of capital. Buying earlier and cheaper helps, but it does not answer that question.

Frequently asked questions

How much did Byhmgard pay for the Hitura project?Terms were not disclosed, and payment occurs in stages conditional on the project reaching ready-to-build. Enerdatics records eleven Finnish development-stage battery transactions during 2026, covering 859 MW, none of which carries a disclosed value, so there is no benchmark for a project of this size.

What is a framework agreement?A framework agreement sets the commercial terms for a series of future transactions without committing either party to a specific asset. It removes the need to renegotiate structure and payment mechanics for each project, which is why this deal moved from letter of intent to binding agreements in roughly five weeks.

When will the Hitura project be built?Hitura is expected to reach ready-to-build stage during 2026, with commissioning expected in late 2027. Byhmgard has taken over the project rights and is responsible for completing the remaining development work up to ready-to-build.
