Innovative utility scalebattery at strategic grid location: Large battery systems play a key role in Germany’s energy transition: they stabilise the electricity grid, help smooth out price fluctuations and ensure renewable electricity is available when it is needed.
BESS Wehr adds 11.5 MW of power and 23 MWh of storage at a strong grid location in Baden-Württemberg, on an existing industrial site close to high-capacity connection points.
Suitable financial structure and fixed interest: The project is financed by a mix of senior bank debt, this subordinated bond and shareholder capital. Investors receive 8.00% fixed interest per year over six years, with quarterly interest payments and repayments starting in 2027.
The project earns revenue across several electricity markets, including grid-stability services such as Frequency Containment Reserve (FCR) and Automatic Frequency Restoration Reserve (aFRR), as well as intraday and day-ahead trading, where flexible storage is financially rewarded.
Ready to build with permits and bank support: The land is secured, key permits are in place, the grid connection is agreed, and a fixed price construction contract is signed. A large German bank has issued a binding collateralized senior loan offer after its own technical, legal and financial due diligence.
Top-tier partners at every step: be.storaged, a German specialist in building and maintaining battery systems, will construct and operate the project. Leading global manufacturers such as TrinaStorage and Power Electronics supply the main technology.
A professional energy-trading partner will manage the battery on the relevant electricity markets (contract finalisation in progress).
Strong climate impact and full SDG alignment: BESS Wehr reduces the need for fossil backup power and helps prevent renewable energy from being wasted. The system provides enough storage capacity to supply around 2,500 households for one day, contributing meaningfully to Germany’s net-zero ambitions.
The project supports SDG 7 (Affordable and Clean Energy) and SDG 13 (Climate Action).

Germany’s energy grid faces a growing challenge: renewable energy sources like wind and solar generate electricity intermittently - only when the sun shines or the wind blows. This leads to frequent imbalances between supply and demand. When too much renewable energy is produced, the grid must curtail it - wasting clean electricity. When too little is available, fossil-fuel backup is still required. These fluctuations threaten both climate goals and grid stability.
BESS Wehr is a large-scale battery project located in Wehr, Baden-Württemberg, on the grounds of a long-standing industrial paper factory. The site is already zoned for industrial use, making it ideal for a storage project without requiring new land development.
The battery can deliver 11.5 megawatts of power and store 23 megawatt hours of energy, which means it can run for about two hours at full output. It is designed to charge and discharge several times a day to support the electricity system with a target cycling rate of 1.8 per day. The project uses proven technology from TrinaStorage for the batteries and Power Electronics for the power conversion equipment.
Grid access is provided by Naturenergie Netze, and the connection has already been secured. All key permits are in place, and a fixed-price construction contract with the specialist builder (EPC) be.storaged has been signed. The project is therefore fully ready to build. Commissioning is planned for 26 November 2026, with time buffers included.
Once operating, BESS Wehr will also be operated and maintained by be.storaged, whereas the asset management will be carried out by 8Energies. In simple terms, the project earns revenue by stabilising the grid and by arbitraging electricity prices: it buys power when prices are low and sells it when prices are high, participates in ancillary services markets, and provides capacity to the grid. The trading of power and capacity is performed by a top-tier German battery optimizer employing advanced AI for real-time dispatch, with over 1 GW of battery capacity currently under management.
The project benefits the local region by strengthening grid stability and by using existing industrial land instead of new greenfield space. It also supports the wider integration of renewable energy in southern Germany, where flexible storage capacity is increasingly needed due to the high renewable energy penetration in the region.
Why Baden-Württemberg and why BESS Wehr?
Baden-Württemberg is one of Germany’s most industrial and energy-intensive regions. As more renewable energy is added to the system, the region increasingly needs flexible storage to keep the grid stable.
BESS Wehr offers ideal conditions for a project like this:
A strategically located grid location in an area that benefits from fast-responding storage
An existing industrial site, avoiding new land development
A secured grid connection from Naturenergie Netze
A local industrial joint venture partner that is familiar with the region and supports long-term project success
This makes BESS Wehr a strategically important asset for the regional energy transition.
How BESS Wehr will deliver value:
Store surplus renewable electricity so clean energy is not wasted
Release power when demand is high or when renewable generation drops
Support grid stability and reduce the risk of local overloads
Lower CO₂ emissions by reducing the need for fossil backup power
Earn revenue on several electricity markets, where flexibility is rewarded
Status of the project:
Ready-to-Build
BESS Wehr has reached ready-to-build status. Key permits are secured, the land is under long-term control through the joint venture with the site owner and a land lease contract, and the grid connection from Naturenergie Netze is confirmed. A fixed-price construction contract with the specialist builder be.storaged is already signed. Construction will begin shortly after financing is completed, with commissioning planned for latest by November 2026.

The Sustainable Development Goals (SDGs or 'Global Goals') are part of the UN 2030 Agenda for Sustainable Development and constitute the international framework for sustainable development until 2030. These SDGs are intended to put an end to poverty, inequality, and climate change.
BESS Wehr plays a direct and measurable role in Germany’s clean-energy transition. As renewable electricity continues to grow, flexible storage becomes essential to keep the grid stable and to ensure that clean power can be used when it is actually needed.
BESS Wehr directly contributes to:
SDG 7 - Affordable and Clean Energy
BESS Wehr makes renewable electricity more usable, predictable and reliable. Instead of letting surplus solar or wind power go to waste, the battery stores it and releases it exactly when households and businesses need it. This increases the share of clean energy in the grid and helps keep electricity affordable by reducing the need for expensive fossil backup plants. By stabilising the system, the project ensures that a renewable-based power supply can work smoothly even as more wind and solar capacity is added across Germany.
SDG 13 - Climate Action
BESS Wehr strengthens the shift away from fossil fuels by stepping in at moments when gas or coal plants would normally be used to stabilise the grid. By providing fast, flexible power from stored renewable energy, the battery reduces the need for these carbon-intensive reserve plants. This leads to lower CO₂ emissions and helps Germany stay on track to meet its climate targets. In addition, by enabling more wind and solar projects to feed their electricity into the grid without curtailment, BESS Wehr increases the overall climate benefit of the renewable system.

Project Developer
To build and commission BESS Wehr, a total investment of €7.99 million is required. This amount covers all construction, equipment, connection, reserve accounts, insurances and advisory costs needed to bring the project from construction to full operation. As shown in the uses of funds, the interest during construction and the reserve account & liquidity buffer are included in the CAPEX budget. This ensures that interest can be serviced during the construction period and that the reserve account & liquidity buffer is pre-funded upfront, preventing a negative impact on operating cash flows in the beginning of the operational phase.

What this means
The majority of the project is financed through a fully collateralized senior loan from a leading German renewable energy financing bank. This means that all the collateral on the assets lies only with the bank, which is why the crowd Investors receive a higher interest rate than the bank. The Invesdor bond provides part of the construction financing and is structured as subordinated debt, ranking below the bank loan but above shareholder loans and equity.
Shareholders (8Energies GmbH and the Jenisch Grundstücksverwaltungs GmbH & Co. KG) contribute €1.27 million of their own capital through shareholder loans and equity, demonstrating their long-term commitment and alignment with investors.
Battery energy storage systems (BESS) earn money by supporting the electricity grid and making better use of renewable energy. They participate in several markets where flexibility and fast response are valuable.
The grid must always stay in balance. Electricity supply and demand need to match every moment.
If there is too much or too little power in the system, the frequency becomes unstable and, in extreme cases, this can lead to blackouts.
Batteries help prevent this by reacting within seconds:
They absorb energy when there is too much electricity
They release energy when there is too little
For offering this fast balancing service, batteries are paid by the grid operator. This creates a predictable revenue stream while improving grid reliability.
Electricity prices move throughout the day. When renewable energy production is high, prices often fall. When production drops or demand increases, prices rise.
A battery takes advantage of these price movements:
It charges when electricity is cheap, often during periods of strong wind or sunshine
It discharges when electricity is more expensive, when the grid needs extra capacity
This “buy low, sell high” approach helps integrate more renewable energy into the system while generating additional revenue.

Fixed-income with attractive investment returns.
Investing always involves risks. Below you can find the detailed list of risks related to this investment, as described in the Key Investment Information Sheet (KIIS). Please review this information carefully before making your investment decision.
The bondholders bear the full risk of the project owner’s insolvency, i.e., the risk that the project owner is temporarily or permanently unable to meet its payment obligations to the bondholders and or third parties on time. Especially in the context of insolvency proceedings, the bondholders could suffer a total loss. The following specific occurrences could lead to this:
There is a risk that, as a result of all of the risks mentioned in Part C, return may be lower than expected, delayed or no principal or interest payments may flow from the project. Furthermore, the value of the return could be reduced by inflation. If the inflation rate is higher than the interest rate on bonds, the return on bonds will be negative. The bonds will be issued in Euro and the interest payable on the bonds will also be calculated and paid in Euro. For this reason, investors who have earned income or assets in a currency other than Euro or who do not require the income from the investment in the bonds to be denominated in Euro are exposed to a currency risk because they are exposed to exchange rate fluctuations which may reduce the yield of the bonds. Furthermore, in the event of a necessary sale of the bonds for the bondholder, additional costs (transaction costs such as consultancy fees) may arise which reduce the return.
The individual return of the respective investor may vary in individual cases and depends on the individual tax situation in each case, which may lead to a reduction in the return.
The following securities-related risks also exist:
