Through its subsidiary Polar Energy, Polar Structure is behind one of the largest battery parks in Skåne – a concrete step toward a more resilient energy system. The new facility in Kristianstad will be inaugurated on 5 May by Minister for Energy and Business, Ebba Busch (Christian Democrats).

The initiative is a collaboration between Polar Energy and C4 Energi, through their jointly owned company Effektbolaget. The battery park, located at Allöverket, contributes to a more flexible and robust electricity grid – both locally and nationally.

– We are seeing how local energy storage is rapidly becoming a key component of the future energy system. With the battery park in Kristianstad, we demonstrate in practical terms how flexibility can strengthen grid stability and pave the way for continued electrification, says Per Langer, CEO of Polar Energy.

The facility consists of modular lithium-ion batteries and can add or remove power from the grid within seconds. This makes it possible to balance the load during power shortages – a recurring challenge during cold winter days in southern Sweden.

– This is an investment we are both happy about and proud of. The battery park is a crucial piece of the puzzle to ensure that Kristianstad can grow and electrify in a sustainable way, says Tore Sigurdsson, Acting CEO of C4 Energi.

The project is driven by Effektbolaget – a joint venture between Polar Energy and C4 Energi. When the battery park is commissioned, the owners’ investments are complemented by external financing from Sparbanken Skåne. In addition to the Allöverket facility, the initiative also includes a smaller battery park at C4 Energi’s head office.

Kristianstad is located in electricity zone SE4 – one of the most strained in Europe when it comes to power availability. With local energy storage, both electricity supply and societal preparedness are strengthened – crucial for continued development in industry, transport, and public services.

– Local flexibility solutions are essential for building a sustainable and cost-effective electricity system. They strengthen our resilience and create long-term value for society as a whole, concludes Tore Sigurdsson.
