European Energy grid-connects 152 MWh of battery storage across two hybrid solar sites in Denmark
AI-madeEuropean Energy just brought two new battery energy storage systems online at solar sites in Denmark. Combined, they add up to 38 MW / 152 MWh of new capacity. The larger one — 28 MW / 112 MWh — sits alongside an 88 MW solar park at Stouby. The smaller, 10 MW / 40 MWh system pairs with an existing 31 MW solar park at Agersted. Both were developed, built, and commissioned within a year.
Two battery systems enter operation at Stouby and Agersted
Stouby is the bigger of the two projects. Its 28 MW / 112 MWh battery system sits next to a solar park that only came online in September 2024—meaning European Energy essentially built a large solar farm and added a substantial battery system to it in rapid succession, both now sharing one grid connection.
Agersted tells a different story. That solar park has been running since 2022, and European Energy retrofitted a 10 MW / 40 MWh battery onto it—handling design, procurement, construction, and commissioning all within twelve months. Between the two sites, that’s 38 MW / 152 MWh of new battery capacity now live on the Danish grid.
Stouby is a newer, larger park where storage was built in as part of a broader push; Agersted is an older, smaller park where storage was added after the fact.
The pace caught the attention of company leadership. Poul Jacobsen, EVP and Head of EPC at European Energy, called the Agersted timeline “another strong achievement,” noting it “required close coordination across engineering, civil works, electrical installation, and system integration.”
Why European Energy is pairing storage with solar generation
The logic behind co-locating batteries with solar is fairly straightforward. Solar is intermittent — it peaks at midday, drops off at night, and shifts with cloud cover. A battery next to a solar park can absorb surplus electricity when the sun’s producing more than the grid needs, then release it later when demand picks back up. At Agersted, that function is built right in: the system is designed to provide grid services including frequency regulation and balancing support, actively helping keep the grid stable rather than just storing energy passively.
The strategy goes beyond the technical side, though. European Energy frames hybridization as a way to unlock extra revenue streams and strengthen the long-term investment case for each service, with a solar park that also offers storage and grid services being simply more versatile than one that only generates electricity.
Thorvald Spanggaard, EVP and Head of Project Development, put it plainly: “Institutional investors are increasingly looking for renewable energy assets that combine stable production with operational flexibility and multiple revenue streams.” Hybrid projects, he added, improve “both asset quality and long-term resilience.” The push toward hybrid assets isn’t purely an engineering decision — it’s about making renewable portfolios more attractive to the large, patient capital that funds infrastructure at scale.
Grid connection strengthens European Energy’s Danish battery portfolio
With Stouby and Agersted now online, European Energy has grid-connected a cumulative 96.75 MW of battery storage in Denmark, providing more than 375 MWh of energy storage capacity across its Danish portfolio. Both installations share a grid connection with their respective solar parks — a practical setup that cuts infrastructure costs and simplifies how generation and storage interact.
Jacobsen cited the Agersted delivery as evidence of “the maturity of our construction organization and our experience in delivering increasingly complex renewable energy projects. ” Stouby was similarly wrapped up within a year, a tight schedule for a system of that scale.
The contrast between the two sites is worth noting. Stouby is a newer, larger park where storage was built in as part of a broader push; Agersted is an older, smaller park where storage was added after the fact. Both followed roughly the same timeline. That points to something more significant than a one-off win — European Energy appears to have developed a repeatable process for this kind of work.
European Energy’s broader battery storage expansion in Europe and Australia
Denmark isn’t the only market where this is happening. European Energy is expanding its battery storage portfolio across Europe and Australia, developing integrated renewable assets that combine generation with on-site storage from the start — or retrofitting storage onto existing sites where it makes sense.
The next milestone is Lithuania, where European Energy says it’ll soon bring its first operational battery storage system online. That would mark the company’s entry into Baltic storage markets, extending a strategy that’s so far been most visible in Denmark. Stouby and Agersted are being positioned as the template: proof that hybrid assets can be delivered on tight timelines and structured to appeal to long-term infrastructure investors.
Expansion is already underway
European Energy has brought 38 MW / 152 MWh of battery storage online across two Danish solar sites — a 28 MW / 112 MWh system at Stouby and a 10 MW / 40 MWh system at Agersted. Both are co-located with solar parks, share their grid connections, and were delivered within a year.
The company’s cumulative battery storage capacity in Denmark now sits at 96.75 MW and more than 375 MWh. The hybrid solar-plus-storage model sits at the center of European Energy’s asset strategy, built around flexibility, multiple revenue streams, and attracting institutional investors. Expansion into Lithuania and other markets is already underway.
