Large-scale BESS projects have been progressed to construction, financing or operations across the EU this week, by project owners, investors and EPC firms re:cap, LONGi, Teos, Flower, Goldbeck Solar, SPP and Tavion.

This week we’ve reported on major battery energy storage system (BESS) project news in the UK, the Czech Republic and Spain. In this piece, we round up the rest of the week’s action on projects that are smaller, but far from insignificant.

The projects proceeding to construction or investment are in Finland, Italy, the Netherlands, Germany, Slovakia and Poland and total well over 1GWh of capacity.

Investor re:cap buys, launches construction on Finland BESS

Re:cap global investors has acquired and is imminently launching construction on the 95MW/220MWh Battery Park Alapitkä project in Finland via its FP Lux European Battery Storage Fund.

The project was developed by SMA Altenso, which will also deliver the full engineering, procurement and construction (EPC) scope including grid and MV/HV works. Its parent company SMA Solar will provide grid-forming inverters, Sungrow will provide the BESS and construction starts this spring for commissioning in H2 2027.

It comes after re:cap recently progressed a 50MW/100MWh project in Freiburg, Germany, which is scheduled for Q2 2027 operations and uses BESS provided by Sungrow.

EPC Goldbeck Solar building two Germany BESS for unnamed owner

EPC firm Goldbeck Solar has received notice to proceed (NTP) on two BESS projects in Germany totalling 100MW/300MWh of capacity, for an unnamed client. Goldbeck is executing the project under a full EPC model, covering system design, supply, construction and a long-term service agreement (LTSA). It follows a recent BESS project win in Poland.

Flower advances Germany BESS projects to RTB

Sweden-based BESS and optimisation platform Flower has advanced internally-developed BESS projects to ready-to-build (RTB) status in Germany. One is a 100MW/400MWh project in Hamburg and the second is 10MW/20MWh in Gersheim. The firm is primarily an optimiser but is also deploying its own projects to prove its long-term optimisation strategy.

Slovakia’s SPP deploying 1MW/2MWh BESS

Slovakian state-owned utility SPP is investing €1 million (US$1.17 million) in a 2MW/4MWh BESS project using technology from China’s Huawei. The project is already connected to the grid and will begin commercial operations soon, it said. It will provide FCR (Frequency Containment Reserve) support services to the grid.

New BESS platform Tavion raises funds, has 300MW RTB in Poland

Sweden-headquartered BESS platform Tavion has raised SEK76 million (US$8 million) in pre-seed funding and SEK500 million (US$54 million) of debt financing for its pipeline, which includes 1.7GW in Poland, of which 300MW is ready-to-build. The firm targets projects in the 15-70MW range, and plans to own and operate its own projects. The team is led by Emad Zand, formerly president battery systems at failed European battery startup Northvolt.

LONGi completes Italy solar-plus-storage project

Solar PV giant LONGi has started commercial operations on a 13.75MW/50.16MWh BESS in Italy. The Montalto project is co-located with an existing 35MW solar PV plant. While the firm is a solar PV technology supplier (and, as of recently, BESS too), this appears to be a case of it investing in and owning its own project. Other China-based renewable tech companies including Trina and Sungrow have done the same in Southern Europe.

Teos signs EPC deal for Netherlands projects

Another EPC firm, Teos, has signed an agreement to build a 15MW/45MWh BESS in the Netherlands, and also chose not to reveal the client.

Held alongside The Battery Show Europe, Energy Storage Summit provides a focused platform to understand the policies, revenue models and deployment conditions shaping Germany’s utility-scale storage boom. With contributions from TSOs, banks, developers and optimisers, the Summit explores regulation, merchant strategies, financing, grid tariffs and project delivery in a market forecast to integrate 24GW of storage by 2037.

Launching September 2026 in Berlin, Energy Storage Summit Germany is a new standalone event dedicated to Germany’s energy storage market. Bringing together investors, developers, policymakers, TSOs, manufacturers and optimisation specialists, the Summit explores the regulatory shifts, revenue models, financing strategies and technology innovations shaping large-scale deployment. With Germany targeting 80% renewables by 2030, it offers a focused platform to connect with the decision-makers driving the Energiewende and the future of utility-scale storage.

Battery Asset Management Summit Europe is the annual meeting for owners, operators, investors, and optimisation specialists working with operational BESS assets across the continent. The Summit focuses on how to maximise performance and revenue, manage degradation, integrate advanced optimisation software, navigate evolving market and regulatory frameworks, and plan for repowering or end-of-life strategies. With insights from Europe’s most active storage markets, it equips attendees with practical guidance to run resilient, profitable battery portfolios as the sector scales.
