European BESS news from project owners Premier Energy Group, Verbund, Eco Stor, Ingrid Capacity, Ric Energy, Ganfeng Lithium, EP Group, RWE and Giga Storage, securing acquisitions, financings and route-to-market (RTM) deals for multiple gigawatts of capacity this past week.
Romania: Premier buys 400MWh BESS, Verbund enlists contractors for project
Energy firm Premier Energy Group has acquired a ready-to-build (RTB) 200MW/400MWh battery energy storage system (BESS) in Romania, near Iasi.
Construction on the project will start in 2026, with commissioning anticipated in late 2026 or early
2027. The project will support the integration or more renewables on Romania’s grid with fast-response capacity and grid balancing applications.
Premier is currently in advanced discussions on financing options for the project, with the expectation of securing a long-term structure, it said. The announcement did not say whether it was one of the winning projects from a recent EU-backed capex support scheme.

In related news, Austria-based utility and power firm Verbund’s local arm Verbund Wind Power Romania has enlisted OEM Prime Batteries and engineering firm Enevo Group to supply and integrate a 48MW/76MWh project.
It will be built at Verbund’s Alpha Nord Wind Farm in Tulcea County. The installation will help integrate more renewables but also improve the operational flexibility of the Verbund’s local renewable assets.
Prime Batteries Technology and Enevo Group will deliver the full engineering, procurement and construction (EPC) scope, including design, equipment supply, system integration, installation and commissioning.
Construction is scheduled to begin in February 2026 with commissioning set for September 2026.
Prime Batteries made headlines last year when it integrated a BESS for owner Monsson with an emphasis on locally manufactured technology.
Germany: Eco Stor project toll and Ingrid Capacity enters market
Project owner-operator and EPC Eco Stor has entered into a long-term toll with energy firm Alpiq for a 103.5MW/238 MWh BESS in Schleswig-Holstein, Germany.
Alpiq will partner with optimisers Enspired and Entelios to manage the BESS project’s activity in the electricity market.
It is Eco Stor’s second major grid-scale project in Germany, and identically sized to its first which came online in June this year, in Bollingstedt. The project with Alpiq in Schleswig-Holstein will come online in mid-2026.
The announcement coincided with one from Sweden-headquartered BESS owner-operator Ingrid Capacity, revealing it has partnered with developer Energiequelle for 200MW of grid-scale projects in Germany.
Energiequelle will develop the projects while finance, operate, and optimise the assets using its in-house trading and optimisation platform. The projects are expected to reach RTB in 2026. Ingrid has so far been active primarily in Sweden and Finland.
Italy: Ric Energy buys 200MW BESS
Spain-headquartered Ric Energy Group has acquired a 200MW BESS in the Apulia region of Italy. The firm’s development pipeline in Italy now stands at 942MW, it said announcing the post on LinkedIn.
It didn’t provide more details about the project in its post. Italy is currently a hotbed of activity, with the long-awaited first auction of its MACSE scheme concluded with 10GWh of BESS handed long-term revenue contracts. Many investors and owner-operators were waiting for the auction before taking FIDs and proceeding to construction.
Our publisher Solar Media will host the Battery Asset Management Summit Europe 2025 in Rome tomorrow and Wednesday (2 & 3 December), where MACSE and Italy will undoubtedly be big talking points.
Netherlands: Giga Storage toll with Vattenfall
BESS owner-operator Giga Storage has entered into a long-term toll with energy firm Vattenfall for its Project Leopard, a 300MW/1,200MWh BESS in the Netherlands.
The toll covers 100MW, one-third of Leopard’s total capacity. It will provide Giga with a fixed, long-term income stream that supports the project’s financing. Vattenfall will optimise the contracted portion of Leopard’s capacity for services such as grid stability, portfolio balancing, and electricity trading.
RTM deals for grid-scale BESS in the Netherlands are characterised by portioning a project’s capacity into different slices with different tollers and offtakers to spread risk, the same strategy adopted by other major BESS owner-operators there including Lion Storage and SemperPower.
UK: RWE to build 700MWh BESS, two optimisation deals announced
Germany-headquartered power firm RWE has made a final investment decision (FID) on a 350MW/700MWh BESS in Wales, called Pembroke Battery Storage. It is part of the wider Pembroke Net Zero Centre project combining renewable generation including green hydrogen production.
The project received planning consent in January 2025 and also won contracts in the UK’s most recent capacity market (CM) auction. Construction will start in 2026 with commissioning and commercial operation in H2 2028, ‘subject to receiving an updated and timely grid connection’, RWE said. That probably alludes to the ongoing grid connection queue reshuffle.
The news follows hot on the heels of two BESS optimisation announcements in the UK, both covered by our sister site Solar Power Portal.
China-based Ganfeng Lithium has enlisted power firm EDF to provide RTM and optimisation services for its 50MW/160MWh Kintore BESS project, while EP Group has contracted optimiser GridBeyond to do the same for its 50MW North Baddesley BESS.
