The news comes ahead of our Energy Storage Summit EU 2026 in London next month, on 24-25 February.
Clean energy arm of petrochemical group completes Greek BESS portfolio
Motor Oil Renewable Energy (MORE) has completed three BESS projects in Greece, totalling 72MW/144MWh of capacity. One of them is pictured above.
The projects are in Phocis, Florina, and Boeotia and each received funding under Greece’s energy storage support scheme, funded by the EU-wide Recovery and Resilience facility. Other projects that won contracts are under construction, including from utility Public Power Corporation (PPC).
MORE is part of the Motor Oil group, an oil refining and petroleum supply firm.
Zenobē puts 300MW/600MWh UK project into operation
Today, Zenobē announced commercial operations at its 300MW/600MWh Kilmarnock South BESS in Scotland.
The site, which began construction in early 2024, deploys Quantum High Energy BESS technology from Wärtsilä and is “strategically located” near several offshore wind farms. Zenobē said the Kilmarnock South BESS will provide stability services to the nearby wind projects using grid-forming inverters, only the second such project in the UK to serve this function – the first is Zenobē’s Blackhillock BESS.
James Basden said: “Kilmarnock South is a landmark moment for Scotland – a world first, subsidy-free battery that will reduce energy bills and strengthen Britain’s energy security.”

Acacia starts building 200MW/400MWh in France
Developer-operator Acacia has launched construction on two projects totalling 200MW/400MWh in France, the first in a 500MW partnership with Eren Group announced a year ago. Eren acquired a stake in Acacia as part of that partnership. The two projects are in the Hauts-de-France and Centre-Val de Loire regions. Based on their combined size, each may be a similar scale to France’s currently largest operational BESS, Harmony Energy’s 100MW/200MWh BESS near Nantes.
Greenvolt finances, construction start on Hungary BESS
Developer and IPP Greenvolt has secured a €58.9 million (US$69 million) financing for a 99MW/288MWh BESS in Buj, Szabolcs-Szatmár-Bereg County, Hungary.
Construction is already underway on the system, which will be completed in Q2 2026. UniCredit Bank Hungary provided the project finance. Greenvolt called it Hungary’s largest BESS.
The project has a ten-year contract from the Hungary government under what Greenvolt called a contract for difference (CfD) scheme.
Greenvolt has emerged as one of Europe’s most notable BESS owner-operators, generally focusing on where there are government-provided long-term revenue contracts. That includes projects in Poland with the capacity market (CM) and Italy with MACSE. The company’s head of storage, Antonio Montoto Rojo, discussed MACSE and the Italian market with us for an ESN Premium article last month.
Rojo was on a panel discussing Hungary and its energy storage support scheme Solar Media’s Energy Storage Summit Central and Eastern Europe (CEE) 2024, when one panellist called the scheme ‘one of the most advanced subsidy schemes to bring energy storage forward’.
NORD/LB finances already under-construction Germany BESS
In other financing news, bank NORD/LB has provided a financing package for owner-operator Eco Stor’s 103.5MW/238MWh Schuby BESS in Germany. Construction on the BESS was slated for November 2024 and it is set to come online in 2026.
Eco Stor entered a five-year toll for it with energy firm Alpiq in late 2025, which enabled this financing which NORD/LB called ‘pioneering’.
Eco Stor launched construction on a larger, c.700MWh project late last year too.
BESS project sales in Finland, Germany and Lithuania
Several developers and owner-operators have in the past week announced ESS project transactions, while not specifying that construction had started.
In Germany, developer Milvio Energy has sold an 80.4MW PV, 70.2MW BESS project that is expected to reach RTB stage in Q2 2026, as well as a 50MW standalone BESS project. It didn’t reveal the buyer for either.
In Finland, developer SENS signed a share purchase agreement with a ‘Frankfurt-based investor’ for the sale of a 85MW/170MWh BESS, in Pyhäsalmi. The project is RTB and closing will take place in the current quarter.
In Lithuania, developer and owner-operator Aquila Clean Energy and investor Energy Gates have closed on a project transaction for a 50MW/100MWh, also RTB. Aquila is primarily known as an owner-operator with major projects in Belgium, Finland and Germany but in this case it sold the project to Energy Gates.
Statera secures planning consent for 8-hour BESS in UK
The Central Bedfordshire planning committee has granted planning approval for a 500MW battery energy storage system (BESS) put forward by Statera Energy.
The developer’s Sundon Storage project will have an 8-hour duration, and as such is one of 77 projects currently under consideration for the Long Duration Energy Storage (LDES) cap and floor support scheme.
An 8-hour duration would give it an energy storage capacity of 4,000MWh.
Whether lithium-ion assets, the technology used in Sundon Storage, would be included in the LDES support scheme was a topic of some debate, before it was clarified that projects would not be excluded “solely on the basis of their technology type”.

France-based NW Group raises €220 million for pan-European BESS plans
French BESS owner-operator has raised €220 million in Holdco financing from institutional investor EIG to expand abroad. It already has an operational portfolio of around 1GWh in France made up of distributed-scale projects built using its proprietary JBox BESS unit, and around 600MWh in Finland. It will also use the funding to expand into Italy and Sweden. It aims to triple its capacity by the end of 2027.
More Germany BESS action
It’s been a particularly busy week in Germany, with several other smaller-scale announcements.
IPP Qair secured planning consent for a 20MW/44MWh BESS in Fuchsstadt, on which construction is set to launch in spring 2026.
Energy firm Seac Group has enlisted EPC and renewable energy solutions firm Sunotec for a multi-phase BESS eventually totalling 230MWh. The first phase will now enter construction for 20MWh, delivered by Sunotec. Sunotec didn’t specify whether it had the contract to deliver the later phases, which are still undergoing internal approvals, grid connection agreements and assessments.
Meanwhile, Voltfang, a developer and system integrator, has completed a 9.5MW/20MWh project for Icecreek Energy. It is located in Alsdorf, in the lignite region of North Rhine-Westphalia. Voltfang has partnerships with other investors, including Tridos and Palladio Partners: we interviewed Palladio and Voltfang on their partnership last year.
