Entech and Eiffage Énergie Systèmes Secure Major Battery Energy Storage Contract in Belgium
Belgium’s ambitions for a cleaner, more resilient energy system have received a major boost with the announcement that Entech, a specialist in energy storage and renewable energy management, has secured a contract to deliver a 170 MW / 340 MWh battery energy storage system (BESS). This large-scale project will be executed through a temporary consortium with Eiffage Énergie Systèmes, a leading player in energy infrastructure. The contract, formally announced on 27 October 2026, marks a significant milestone for Belgium’s energy sector and underscores the growing importance of advanced storage solutions in supporting the country’s energy transition.
Collaboration between industry leaders for grid transformation
The newly signed contract is the result of a strategic partnership between Entech and Eiffage Énergie Systèmes, who have worked together in a joint venture since 2024. Over the past two years, this collaboration has enabled the partners to secure and deliver several high-profile energy storage projects. Their combined expertise brings together Entech’s technological innovation in intelligent energy management and Eiffage’s extensive experience in managing and executing complex, large-scale infrastructure projects. This latest contract for the Belgian BESS stands as the final major project for the joint venture, which is set to conclude once current projects under construction are completed. Despite the end of the formal partnership, both companies have stated their intention to continue working together in similar forms, recognising the value of their complementary skills in tackling the challenges of modern energy infrastructure.
This contract not only cements the reputation of Entech and Eiffage Énergie Systèmes as leaders in the energy storage sector, but also signals Belgium’s commitment to investing in flexible, future-ready grid solutions. As the share of renewables in the energy mix increases, so does the need for robust storage systems capable of balancing supply and demand in real time.
Technical significance of the 170 MW / 340 MWh battery storage system
The planned battery energy storage system is designed to provide 170 MW of power with a storage capacity of 340 MWh, making it one of the largest projects of its kind in Belgium. Such a facility will enable the grid to absorb surplus electricity generated during periods of high renewable output—such as sunny or windy days—and release it when demand rises or renewable generation falls. This not only helps to maintain grid stability, but also maximises the utilisation of renewable resources by minimising curtailment and supporting frequency regulation.
Battery energy storage systems at this scale require sophisticated integration of hardware and software. Advanced control systems must monitor grid conditions in real time, dispatching stored energy as needed to balance fluctuations. The design and construction process involves multiple engineering disciplines, including electrical engineering for power conversion and grid connection, systems engineering for control and automation, and civil engineering for site development and safety compliance. The project’s technical complexity highlights the critical role of multidisciplinary engineering teams in delivering reliable, high-performance energy infrastructure.
For Belgium, the deployment of such a large BESS is a strategic investment to enhance energy security and support the integration of renewables. As the country—and Europe as a whole—accelerates its transition to low-carbon energy, storage solutions like this are becoming central to grid management and flexibility.
Engineering and project delivery: expertise at the core
The successful execution of a project of this magnitude relies on a broad spectrum of engineering and project management skills. From initial feasibility studies and system design to procurement, construction, and commissioning, each phase demands close coordination among technical experts. Electrical engineers design the high-capacity battery arrays and manage grid interconnections, while automation specialists develop the control algorithms that ensure safe and efficient operation. Project managers oversee timelines, budgets, and stakeholder communication to keep the complex build on track.
Entech’s focus on intelligent energy management and Eiffage Énergie Systèmes’ experience in delivering infrastructure at scale demonstrate the value of partnerships that blend innovation with operational excellence. This approach not only improves project outcomes but also provides a framework for future collaborations in the rapidly evolving energy sector.
The Belgian BESS project also illustrates how engineering and technical professionals are central to the success of the energy transition. Their expertise is required not only to deliver the physical infrastructure, but also to ensure that it integrates seamlessly with the existing grid and supports wider energy policy objectives.
Opportunities for engineers and technical professionals in energy storage
The announcement of this major BESS contract in Belgium reflects the increasing relevance of battery energy storage in Europe’s energy landscape. Engineers and technical professionals with skills in power systems, renewable integration, automation, and project management are at the forefront of this transformation. As Belgium continues to invest in grid flexibility and renewable support infrastructure, projects like this will remain pivotal in shaping the country’s energy future.
