A trio of German grid-scale BESS news items, with Next Kraftwerke and ju:niz Energy agreeing a seven-year toll, Alpiq announcing a 370MW pipeline, and WBS Power selling the country’s largest solar-plus-storage project and planning a data centre on the same site.
Germany has this year become a hotbed of battery energy storage system (BESS) project announcements and deal-making, driven by its substantial revenue opportunities as Europe’s largest electricity market and a looming August 2029 deadline for getting projects operational to avoid charge-discharge grid fees. See all recent coverage here.
Developer WBS Power has sold the 150MW solar, 500MW/2,000MWh BESS Project Jupiter in Brandenburg, Germany, to investor Prime Capital.
WBS acquired the site for the clean energy project in 2022, and the project will require €500 million (US$583 million), with construction expected in late 2026/early 2027. Both technologies will share a 380kV grid connection in the area of TSO 50Hertz. The acquisition is subject to Project Jupiter reaching ready-to-build (RTB) status.
The transaction also establishes a joint venture to co-locate a hyperscale data centre of up to 500MW in power demand in the same area.
WBS Power said there is growing demand for data centres in Germany, which are highly energy-intensive and benefit significantly from direct access to renewable power and grid stability.
“By integrating Germany’s largest co-located BESS and Solar PV project with a hyperscale data center, we are creating a unique platform that supports both the energy transition and digital transformation,” said Maciej Marcjanik, CEO of WBS Power Group.
Switzerland-based energy firm Alpiq has expanded in Germany with a 370MW BESS pipeline the company has ‘secured’, in partnership with developer SPP Development. The projects in Brandenburg and Saxony-Anhalt are expected to reach RTB status in 2026.
Lukas Gresnigt, Head International and member of the Executive Board of Alpiq said that Germany is a competitive and complex market for BESS, with many projects are queuing for grid access and permits, and the partnership combined Alpiq’s financial strength and SPP’s local expertise.
Last week, Energy-Storage.news reported on Alpiq entering into a long-term toll for a BESS in Germany owned and operated by Eco Stor. Alpiq has acquired projects in France and Finland, where it recently commissioned a 30MW/36MW project.
VPP operator Next Kraftwerke, acquired by Shell in 2021, has concluded a Germany BESS toll with BESS platform ju:niz Energy, acquired by investor EQT in 2024.
The seven-year toll is for a 20MW/40MWh project in Vöhringen, Bavaria, and Next said it is one of the first operational contracts of its kind in Germany, live since 1 November.
Next Kraftwerke will pay ju:niz Energy a fixed monthly fee per installed MW for the use of the BESS capacity. The model offers stable revenues for the operator (ju:niz) and flexibility for the optimiser (Next Kraftwerke). The toll is 80% fixed remuneration and 20% merchant, Next said.

The facility will be constructed in two phases and located next to the Marguerite Lake substation to enhance efficiency and facilitate grid integration. Image: EllisDon
Compressed air energy storage (CAES) developer Cache Power is partnering with construction company EllisDon to deliver a CAES facility in Northeast Alberta, Canada.
The facility will be constructed in two phases and located next to the Marguerite Lake substation to enhance efficiency and facilitate grid integration.
Cache Power does not have any information on its website, but appears to be a special purpose vehicle (SPV) for Federation Engineering.
On Federation’s website, the company clarifies that the Marguerite Lake facility will have a 250MW load capacity and 640MW generation capacity. Energy storage capacity or planned duration were not referred to in publicly available materials.
The companies assert that the technology will be essential in stabilising Alberta’s grid and supporting both provincial and national efforts toward a net-zero electricity future. The project has secured all key regulatory approvals, with early construction scheduled to start soon.
CAES technology operates by pressurising and directing air into a storage medium to load the system. When discharging, the stored air is released through a heating system to expand, driving a turbine generator.
Notably, the companies claim the project will be the first commercial scale CAES facility in Canada.
Ontario-headquartered Hydrostor is known for its advanced compressed air energy storage (A-CAES) projects.
A-CAES operates similarly to traditional CAES but captures heat from the compressor and passes it through heat exchangers to store in pressurised water. This water is kept in a reservoir and then released into a cavern to displace air during discharging, a process known as hydrostatic compensation.
In conventional CAES, less than 50% of the energy can typically be recovered. The thermal energy produced during compression is often wasted, and the power output varies depending on the residual underground air pressure.
Hydrostor has two small operational projects in Canada, one a pilot and the other a commercial demonstrator, with the larger one being a 2.2MW/10MWh commercial system in Goderich, Ontario.
Hydrostor noted the Goderich Energy Storage Centre as the world’s first commercially contracted A-CAES facility. In addition to its role as technology provider, the A-CAES company is also developing large-scale projects around the world, including its 1.6GWh Silver City project in New South Wales, Australia, and 4GWh Willow Rock project in California, US. The company has secured some funding and offtake agreements for both, including a recent renegotiation of contracts for Willow Rock (ESN Premium article).
It has also proposed a 500MW/8,000MWh project in Ontario (ESN Premium), adjacent to Ontario Power Generation’s Lennox Generating Station in Greater Napanee.
Speaking with Energy-Storage.news, a representative from Federation clarified that the distinction between the CAES system titles for itself and Hydrostor came down to scale and usage.
Cache Power’s facility can store up to 48 hours of energy by compressing air with excess grid electricity and sequestering it in underground salt caverns formed through solution mining.
It can also blend up to 75% hydrogen with natural gas, with a future plan for complete hydrogen utilisation, aligning with Canada’s net-zero ambitions.
Power plant equipment supplier Babcock & Wilcox are collaborating on engineering the possible hydrogen facility expansion, employing the company’s BrightLoop technology.
Babcock & Wilcox claim that BrightLoop can produce hydrogen while isolating carbon dioxide for capture and storage.
Additionally, Cache Power states it will deliver economic and social advantages to the local community and Indigenous Partners. Cold Lake First Nations has actively engaged in the project’s development and is anticipated to collaborate as a partner with Cache Power in both the project and its operations.
Update: Jordan Costley, Director of Sustainability Projects at Federation Engineering, and President of Cache Power has clarified that the project will be 30.72GWh. Costley also added about CAES energy recovery:
“(The 50% recovery statistic) may have been true for the original D-CAES projects such as Huntorf (Germany 1978) and McIntosh (USA 1991) but our project is utilizing the latest D-CAES technology from Siemens Energy.“
“Today’s compression technology utilising multi-stage integrally geared and intercooled compressors is very efficient resulting in the heat of compression being low grade not valuable for thermal energy storage and reuse in the expansion process. The expander trains also include 90% effective dual-reheat recuperators again significantly increasing the overall efficiency. The technology we are utilizing is not “conventional CAES” as defined by Huntorf and McIntosh.

The World Bank will invest in a huge 4GW, 5.12GWh solar-plus-storage complex in Malaysia, which will form part of a pan-Southeast Asian power grid initiative.
The Southern Johor Renewable Energy Corridor (SJREC) will be a roughly 2,000sqKm area dedicated to solar PV and energy storage capacity. The US$6 billion project is backed by the World Bank’s private investment arm, the Iternational Finance Corporation (IFC), alongside the state investment firm of Johor, Permodalan Darul Ta’zim (PDT), and Ditrolic Energy, a Malaysian integrated energy company.
The project is part of a number of larger schemes, chiefly the ASEAN Power Grid Initiative, a plan to integrate power grids and energy supply across Southeast Asian nations. In this vein, the SJREC will be part of the Johor–Singapore Special Economic Zone (JS-SEZ) “masterplan”, able to transmit clean energy to Singapore, which sits on Johor’s southern border.
As a densely populated city state, Singapore relies heavily on energy imports and has made significant plans for cross-border renewables transmission, perhaps most notably the mammoth AA PowerLink project in Northern Australia, which aims to deploy almost 20GW of solar capacity when fully operational and supply power to Singapore via undersea cables.
The site is also part of the Johor Green Development Policy 2030, which the state government introduced to expand its green industries and renewable energy developments.
“As the state agency entrusted to formulate the Johor Green Development Policy 2030, PDT is proud to witness our strategic framework transition into tangible reality today,” said Dato’ Ramlee bin A Rahman, president and group chief executive of Permodalan Darul Ta’zim.
“The Southern Johor Renewable Energy Corridor was conceived as the cornerstone of this policy, specifically Strategy one, to unlock the immense solar potential of the Kota Tinggi and Mersing districts.”
Tham Chee Aun, CEO of Ditrolic Energy, said the SJREC hub would “Anchor Johor’s clean energy export potential and provide a foundation for industries seeking renewable, low-cost power in the region.”
In an announcement, the IFC said the project would supply renewable energy to “local and multinational corporations, including hyperscale data centre operators, manufacturers, and other businesses in Johor”.
Renewables development is a major driver for meeting data centre power demand, primarily because of the affordability of solar projects and solar energy and the stability offered by coupling the technology with energy storage. In its most recent report, the International Energy Agency (IEA) said the world would become “thirsty for energy” in the coming years and that data centres were an “Important driver” of growing power demand.
