Blykalla advances planning for SMR park in Gävle

Press ReleaseMarch 19, 2026

Stockholm, Sweden

Blykalla will proceed with the next phase of planning for a small modular reactor park in Norrsundet, Gävle, Sweden. The company aims to initiate the permitting process in 2026, following initial assessments confirming that the site offers suitable conditions for fossil-free energy production.

The proposed park is envisioned to consist of six of Blykalla’s lead-cooled SEALER reactors, with a total capacity of approximately 300 MW. This corresponds to the electricity demand of around 150,000 households, a large-scale industrial operation, or a medium-sized data center. The project is expected to generate 300-400 direct jobs, as well as several thousand indirect employment opportunities in the region.

"The decision to move forward in Norrsundet is based both on the site’s favorable conditions and the growing need for stable, fossil-free electricity to enable industrial development. Gävle is a strategically important location where new power generation can support long-term growth and strengthen competitiveness."

— Jacob Stedman, CEO of Blykalla

The project is subject to approvals from several authorities, including the Swedish Radiation Safety Authority, the Land and Environment Court, the Swedish Government, and Gävle Municipality. Subject to the necessary permits and final investment decisions, the facility could become operational in the first half of the 2030s.

Blykalla will now continue site investigations and detailed studies, alongside maintaining an open and ongoing dialogue with local stakeholders as the project progresses.

Blykalla looks forward to sharing further updates regarding the progress of the site investigation and the upcoming steps in the planning process within the coming weeks.
