Another busy week of BESS news from across Europe, with investors and owner-operators ABO, Field, Aspiravi, Prime Capital, Latvenergo, Sonnedix and Amarenco progressing large-scale projects across Europe. All-in-all the projects being commissioned, built or financed total around 700MWh.
ABO and Field commission Germany BESS
Owner-operator Field has commissioned a 16MW/33MWh battery energy storage system (BESS) project in Waldkappel, Hesse, Germany.
ABO Energy sold the facility to Field in Q2 2025 but it was the company to announce the project coming online, and indicated it may have been involved in the construction stage too.
ABO said that the system components used for the BESS are not housed in shipping containers as is usually the case, but in modular racks mounted on a steel frame.

“Waldkappel is our first German project and a strong example of how quickly and reliably modern battery storage systems can be implemented today,” said Field general manager Philip Hainbach.
Field is UK-based, having built its first projects there, but is active elsewhere in Europe, including Italy.

Aspiravi starts building Belgium BESS, Centrica to optimise Renner’s
Renewable independent power producer (IPP) Aspiravi has started construction on its first BESS project, a 60MW/240MWh system in Belgium. It is expected to be operational in 2027, and is being built on a site that formerly housed the company’s HQ.
In related news, trading and optimisation firm Centrica Energy has signed a five-year flexibility purchase agreement (FPA) with Renner Energies for its Virton BESS project in Virton, Belgium. Renner started building the 12MW/24MWh project in November 2025 and expects to commission it this year.
Centrica Energy is part of UK-headquartered power firm Centrica. The deal is a partial fixed-price product structure that Centrica claimed is the first of its kind in Belgium.

Latvenergo orders BESS for Latvia project from Merus Power
System integrator Merus Power will supply two 20MW/40MWh BESS orders for contractor Nordes Būve for projects in Latvia being built for owner Latvenergo. The projects are likely part of a larger pipeline that Latvenergo, a state-owned power and utility firm, is deploying in the country.
The contract between Latvenergo and Nordes Būve is €22.5 million (US$26 million), with Merus Power’s overall scope of equipment delivery and multi-year lifecycle services up to €13–15 million depending on contractual options exercised. It is Finland-headquartered Merus’ first project in Latvia.

Prime Capital buys Finland BESS project
Germany-headquartered Prime Capital has entered the Finnish market with the acquisition of an 85MW/170MWh BESS project from developer SENS. The total purchase price is €5.5 million. Prime Capital was in the headlines in December for a 500MW/2GWh BESS project in Germany it invested in.

IPP Sonnedix secures financing for solar-plus-storage projects in Portugal
Spanish IPP Sonnedix has secured financing for its first hybrid solar-BESS projects in Portugal.
The funding will support the 28MW solar and 24MW BESS Acail project in Ovar, Aveiro, and the 40MW PV and 32MW BESS Felgueiras project in Nisa, São Matias, Beja. The solar plants are expected to enter operation in the second quarter of 2026, followed by the BESS in the third quarter.
According to the company, the transaction represents one of the first commercial bank-backed structured financings in Portugal for hybrid solar PV and battery energy storage projects.
Sonnedix said it expects to secure additional financing for hybrid BESS projects in other key markets, including Spain and Italy, as it expands its portfolio of solar-plus-storage assets across Europe.

IPP Amarenco doubling capacity of French BESS
Ireland-headquartered IPP Amarenco has raised a €65 million debt facility for the repowering and augmentation to its Claudia BESS project in France.
It was originally designed and deployed in 2024 as a 105MW/100Wh, roughly 1-hour system, but is being expanded to 94MW/188MWh. The firm didn’t specify why the power capacity is being reduced. One reason could be that reducing power capacity does, in effect, help to increase the duration.
The battery deliveries for the augmentation are expected in the current quarter, with commercial operation by 2027. The project has a long-term toll with power firm Engie.
