Municipalities as Pioneers of the Energy Transition: Ensuring Supply and Strengthening Value Creation

Battery storage systems strengthen the local energy infrastructure, enhance security of supply, and support municipal climate protection goals. We develop projects that integrate seamlessly into regional planning, engage residents, and foster sustainable local economic growth. If your municipality has suitable land available, you will also benefit from lease income and, in combination with wind and solar farms, from attractive payments under the municipal levy program.

Operators of wind and solar farms Increase their revenue with BESS

Connecting generation facilities to battery storage systems improves the economic efficiency of your energy park: You increase marketing flexibility, smooth out feed-in profiles, and avoid curtailment. We help you optimally integrate storage systems into existing or new energy parks—technically sophisticated, beneficial to the grid, and highly profitable.

One location - four possibilities

Standalone, co-location, gray electricity, or green electricity storage: There are several options for implementing storage projects. We’ll explain them.

Stand alone

A stand-alone battery storage system is connected directly to the power grid and operates independently of wind or solar power generation. This type of system always stores “gray electricity,” since the stored electricity corresponds to the current mix of power from the grid.

Co-location – not built over

The rated capacity at the substation corresponds to the total connection capacity of the renewable energy plants and the BESS; each technology can operate independently without the risk of curtailment. The storage system can be charged both from the grid and from the renewable energy plants (gray). However, this does not result in efficient use of the grid connection.

Co-location – built over

The total connection capacity of the renewable energy systems and the BESS intentionally exceeds the committed capacity at the substation, which allows for more efficient use of the connection. Subject to certain restrictions, the storage system can also be supplied from the upstream grid (gray).

Co-location with Green Electricity

If the storage system stores only electricity from connected PV or solar farms, it is referred to as a green energy storage system. It is charged exclusively with renewable energy, stores it temporarily, and feeds it into the power grid as needed. Excess electricity from the grid is not accepted.

How a Battery Storage System Is Built

I Site Selection

II Technical Concept & System Design

III Permit Management

IV Construction & Commissioning

Site Selection

This is where the foundation for a successful BESS project is laid. The first step is to submit a grid connection request to the relevant grid operator to verify technical feasibility and available capacity. At the same time, a regulatory assessment is conducted to analyze potential restrictions, requirements, and opportunities at the site. Based on this information, a financial feasibility analysis is conducted to assess the project’s economic viability. Another important step is securing the site by entering into a lease agreement that guarantees long-term use of the location. In addition, the project is presented to the community during this phase to ensure transparency, answer questions, and foster local acceptance.

Technical Concept & System Design

This is where the key technical parameters of the BESS project are defined. First, the appropriate storage technology is selected, with criteria such as efficiency, service life, safety requirements, and cost-effectiveness playing a decisive role. Based on this, the power and capacity are designed to optimally tailor the storage system to the planned application scenarios and grid requirements. At the same time, the grid connection route is planned. Another key component of this phase is the development of comprehensive safety and fire protection concepts that meet the high requirements for the operation of energy storage systems. In addition, the team examines how the storage system can be effectively integrated into existing energy facilities, such as wind or solar farms, to efficiently manage the overall energy flow.

Permit Management

In the area of permitting management, we guide the project through all necessary regulatory procedures and ensure a smooth process. This includes comprehensive support for the building permit application process—from compiling all required documents to submitting them by the deadline. In addition, we prepare all relevant reports, including noise, fire safety, and environmental assessments, which form the basis for legally sound approvals. Another key component is ongoing communication with authorities as well as active stakeholder management. This ensures that open questions are clarified early on, requirements are coordinated, and a constructive dialogue with all parties involved is maintained.

Construction & Commissioning

During this phase, the BESS project is implemented. Based on the technical concept, detailed and construction planning is carried out first, precisely defining all structural and technical requirements. The necessary components are then procured—ranging from battery systems and transformers to the entire electrical and control systems. As the general contractor, JUWI coordinates the entire construction process and manages all trades. A comprehensive quality and safety management system ensures that the highest technical standards are maintained and all legal requirements are met. Once construction is complete, a test operation phase begins, during which all systems are thoroughly tested and optimized before the storage system is fully commissioned.
