Grid-scale energy storage solutions provider Energy Vault Holdings Inc. has signed a framework agreement with EU Green Energy LLC for the deployment of battery energy storage systems (BESS) totalling up to 1.8 GWh across the Balkan region. The total value of the deal could reach $250mn, with implementation planned over four years.
Initial 200 MWh project in Albania
The first project under this agreement will be located in Kulluricë, southern Albania. It involves the installation of a 50 MW / 200 MWh system using Energy Vault’s B-VAULT™ platform and its VaultOS™ energy management system. Commercial operation is expected in Q3 2026, with a second phase of 50 MW / 200 MWh scheduled for Q1 2027. The project is subject to final legislative approval by the Albanian authorities.
The agreement also outlines plans for regional expansion. EU Green Energy, which develops renewable energy assets in the Balkans, aims to roll out additional deployments in neighbouring markets including Kosovo, Montenegro and North Macedonia.
Strategic partnership for regional expansion
Energy Vault’s technology platforms are central to the agreement. According to both companies, the integrated hardware and software solutions are designed to optimise project returns while supporting grid flexibility in a region undergoing rapid energy sector development. The partnership comes as Balkan countries seek to modernise infrastructure and diversify energy sources.
Energy Vault stated that the deal marks a new step in the growth of its global commercial portfolio. Its B-VAULT™ platform now includes more than 2 GWh of deployed or contracted systems worldwide.
Expanding a growing global presence
The framework deal was structured under an Energy Equipment and Services Agreement (EEQ), covering Phase 1 of the Albanian project. This contractual arrangement allows EU Green Energy to secure the required technologies while maintaining execution flexibility across the targeted markets.
Energy Vault, headquartered in California, continues its expansion into growth markets by partnering with local players for on-the-ground execution. This transaction strengthens its strategic entry into emerging European energy markets.
