Alight announced the acquisition of a large-scale solar and battery energy storage project under development in Denmark, marking a significant expansion of its Nordic renewable energy pipeline. The project, located in Kalundborg on the island of Sjælland, combines a 79 MWp utility-scale solar park with a co-located 55 MW battery energy storage system and represents the company’s first integrated solar-plus-storage initiative in the Danish market.
The project was acquired from GreenGo Energy and will continue to be jointly developed by both companies until it reaches ready-to-build status, which is currently expected in 2028. It also represents the first collaboration between Alight and GreenGo Energy in Denmark, establishing a partnership focused on advancing hybrid renewable energy infrastructure.
Spanning approximately 90 hectares, the Kalundborg site is expected to generate around 95 GWh of electricity annually. Among the roughly 7 GW of projects evaluated by Alight in Denmark, this project stood out due to strong return potential driven by high solar irradiation, optimized system design, and favorable land and grid conditions.
A key feature of the development is the integration of battery storage alongside solar generation. The co-located 55 MW BESS enables energy produced during peak solar hours to be stored and dispatched later, improving grid flexibility and increasing the overall value of the electricity generated.
The project remains in early development stages, with land lease agreements secured and zoning and environmental permitting processes currently underway. Once operational, the facility will support long-term power purchase agreements, under which Alight will own and operate the assets while supplying electricity to commercial and industrial customers at fixed, low prices.
This acquisition builds on Alight’s growing presence in the Nordic region. The company previously acquired a 215 MWp solar park in Lolland, Denmark, in 2025, which was commissioned later that year and ranks as one of the largest solar installations in the Nordics. The Kalundborg project also contributes to Alight’s broader ambition of reaching at least 5 GW of installed capacity by 2030, alongside developments in Finland and Sweden.
KEY QUOTES:
“We’re excited to add a solid project to our development pipeline and expand our Danish portfolio. This hybrid park is a fully integrated solar-plus-storage project in one of the most strategic locations in Denmark. By combining solar with BESS in DK2, we can generate renewable power where and when it is most needed.”
Warren Campbell, CEO, Alight
“We are very pleased to partner with Alight on this first project together in Denmark. GreenGo will continue as development partner through ready-to-build, and we see Kalundborg as a strong first step in supporting Alight’s ambitious vision in the Nordics”
Karsten Nielsen, CEO, GreenGo Energy
