Our Services for Battery Energy Storage Systems

We support battery storage projects across their entire life cycle. As an EPC provider, we take care of engineering, procurement, and construction. As a distributor, we supply storage systems and the matching system components. And during operation, we ensure high availability through maintenance, support, and monitoring.

Our solutions enable targeted grid connection point optimisation, reduce peak loads, increase self-consumption, and unlock additional revenue potential through flexibility marketing and revenue optimisation. Different operating strategies and marketing options can be intelligently combined with one another.

EPC Provider

As an EPC provider, we implement scalable battery storage solutions for commercial and industrial applications, as well as stand-alone and co-location projects in wind and solar farms. Drawing on our technical expertise, long-standing industry contacts, and direct access to international BESS manufacturers, we combine high-quality storage technologies with practical project implementation – reliably, cost-effectively, and tailored to our customers’ needs.

Engineering

We handle the technical planning, sizing, and design of the battery storage system – tailored to the location, grid connection, power requirements, and the planned operating strategy.

Procurement

Through our network of partners and suppliers, we select and procure suitable storage technologies as well as key components such as inverters, transformers, and other system components.

Construction

We handle the coordination and implementation of the project through to commissioning – including interface management, installation, technical integration, and coordination among all relevant project stakeholders.

BESS Distributor

We supply scalable battery energy storage systems and compatible system components for commercial and industrial applications. Our portfolio includes storage solutions across various capacity ranges, as well as skid-mounted systems for direct connection to medium-voltage networks.

Upon request, we also support end customers with selected distribution services, providing access to high-quality storage components and fully integrated system solutions.

To bring our storage solutions to market more effectively, we also collaborate with selected sales partners who distribute our products to end customers and expand our market reach.

Operations & Maintenance

We ensure the reliable operation and maximum availability of your battery energy storage solution.

Our services include scheduled and unscheduled maintenance, first-, second-, and third-level support, spare parts management, continuous monitoring, and technical optimisation. This keeps your system safe, efficient, and cost-effective throughout its service life.
