European multi-technical services company SPIE has signed a European framework agreement with Tesla for the implementation of battery energy storage system (BESS) projects, further strengthening an existing collaboration between the two companies.
The agreement, which has a three-year term with an option for renewal, applies to all SPIE subsidiaries across Europe that have expertise in BESS installation. It establishes a standardized legal and operational framework for SPIE’s involvement in projects using Tesla’s Megapack technology.
Under the agreement, SPIE will deliver a comprehensive range of technical services, including engineering and balance-of-plant (BoP) work, connection to high- and medium-voltage electricity grids, installation of security, lighting, fire detection and surveillance systems, and commissioning of battery energy storage facilities.
The framework initially covers activities in France and opens opportunities in other European markets, notably Poland and Germany, where SPIE subsidiaries have demonstrated strong technical and operational capabilities in large-scale energy infrastructure projects.
The partnership builds on an already established working relationship between SPIE and Tesla, supported by several major energy storage projects currently under construction or already completed across Europe.
In Ville-sur-Haine, Belgium, SPIE is responsible for the installation of a 50 MW / 200 MWh battery energy storage system comprising 53 Tesla Megapacks. In the Netherlands, the company is participating in the Mufasa project in Vlissingen, which is set to become the country’s largest battery energy storage facility. The project will include 372 Megapacks, delivering a total capacity of 1.4 GWh, and is designed to support grid flexibility and renewable energy integration. In France, SPIE is leading a project in the Eure department involving the installation of a 100 MW / 200 MWh BESS unit.
Commenting on the agreement, Tobias Zaers, Business Development and Marketing Director at SPIE, said:
“This agreement reflects the confidence that a key global player in the energy sector has placed in SPIE’s technical skills and pan-European organisation. We have developed collaboration between our subsidiaries with the systematic sharing of experiences, which allows us to capitalise on our national expertise. By combining our industrial know-how, local presence and collective intelligence, we are actively contributing to building a more sustainable energy model that is based on reliability, performance and efficiency.”
The agreement further consolidates SPIE’s position in the European utility-scale battery energy storage market, as deployment of large-capacity systems continues to expand across the region.
