Building Energy Resilience: Exploring Battery Storage Across the CTPark Network

From a new large-scale installation in Germany to ongoing operations at CTPark Amsterdam City, CTP is building practical experience with energy storage and exploring how these systems could support the future of business park infrastructure.

As renewable energy continues to grow, battery energy storage systems are becoming an increasingly important part of the modern energy landscape. They help balance supply and demand, improve grid stability, make better use of available energy, and support the development of more flexible and resilient business park infrastructure.

CTP is expanding its practical experience with this technology through projects at CTPark Wuppertal in Germany and CTPark Amsterdam City in the Netherlands.

At the end of June 2026, CTP’s first battery energy storage system (BESS) went into operation at the park, located in the heart of the Bergisches Land in North Rhine-Westphalia.

Planned and implemented together with Schoenergie GmbH, the project represents an investment of around €4 million. For CTP, it marks an important step in exploring how battery storage could help strengthen the resilience of the CTPark Network’s energy infrastructure.

Power on demand

The principle is simple: store electricity when it is available and economically attractive, then feed it back into the grid when it is needed.

The system in Wuppertal is a pilot project, designed as a stand-alone grid electricity storage system. It is not connected to a solar park or a dedicated substation. Instead, it stores excess electricity from the grid. In the pilot phase, this enables the stored energy to be traded on the electricity market.

The potential, however, goes much further. Battery storage systems can become a key component of the energy infrastructure of modern business parks. They can help reduce peak loads, optimise energy consumption, and make energy supplies more reliable. At the same time, they can provide valuable balancing services, supporting the integration of renewable energy into the power grid.

For CTP, the project in Wuppertal is therefore more than a technical installation. It is a real-world case study and learning project, allowing CTP to gain practical experience with battery storage, assess its potential, and lay the groundwork for integrating flexible energy solutions more robustly into the infrastructure of its business parks in the future.

The system consists of three battery storage units, two central inverters and one grid connection station. Together, the batteries provide a storage capacity of 15.045 MWh and a rated power output of 2 x 3.96 MVA. Construction started in October 2025, physical completion was achieved in February 2026, and the system was commissioned at the end of June.

BESS in practice: CTPark Amsterdam City

CTP is also gaining operational experience with battery storage at CTPark Amsterdam City in the Netherlands. The park currently operates a 1 MW battery alongside a 5 MW photovoltaic system and a 10 MW grid connection.

The battery is used primarily for energy trading. It charges either from the grid when electricity prices are low or negative, or from the park’s solar installation, and discharges energy back to the grid when electricity prices are higher.

Building on this experience, CTP is currently exploring the potential for a larger 10 MW battery energy storage system at the park. While the site’s available grid capacity means the battery is not currently needed for peak shaving or tenant energy supply, a larger installation could create additional value through energy trading while providing further insight into the role battery storage may play in the future development of the CTPark Network’s energy infrastructure.
