The site in Kalundborg combines a 79 MW utility-scale solar park with a co-located 55 MW battery energy storage system (BESS). Spanning around 90 hectares, it is expected to generate roughly 95 GWh annually.
Among the 7 GW of projects Alight has assessed in Denmark, Kalundborg stands out for its return potential, supported by relatively strong irradiation, an optimised layout and favourable land and grid conditions. The integrated 55 MW BESS is central to the design, enabling energy to be time-shifted behind a single grid connection and supporting the overall value of the project’s output.

The Kalundborg project remains at an early stage, with a land lease secured and zoning and environmental permitting under way. Alight and GreenGo Energy will continue joint development until the project reaches ready-to-build status, currently expected in 2028.
The hybrid plant is intended for long-term power purchase agreements (PPAs), under which Alight will own and operate the assets and supply electricity to commercial and industrial customers at fixed prices. Alongside projects in Finland and Sweden, Kalundborg marks a step towards the company’s target of at least 5 GW of installed capacity by 2030.
In 2025, Alight acquired a 215 MW solar park under construction in Lolland from European Energy, which was commissioned later that year. The Lolland project is the second-largest solar facility in Denmark and the Nordics. (hcn)
