SPIE SA has announced the signing of a European framework agreement with Tesla for the implementation of battery energy storage system (BESS) projects. The agreement, which has a renewable term of three years, applies to all European SPIE group subsidiaries with BESS installation expertise. It will standardise the legal and operational conditions of Megapack projects installed by SPIE across Europe and supports the integration of renewable energy sources into power grids. The agreement builds on previous cooperation between SPIE and Tesla in Belgium, the Netherlands, and France, and is expected to facilitate further projects in countries including Poland and Germany.
