Swiss energy storage provider Energy Vault has signed an agreement to supply up to 2 GWh of battery capacity for the solar power projects of Turkey-based Astor Enerji in Romania. Astor Enerji, for its part, will provide transformers and high-voltage equipment for more than 1 GW of Energy Vault’s battery projects worldwide.

Astor Enerji recently entered the Romanian market through the acquisition of four photovoltaic projects with a total capacity of 279 MW, according to reports. The transactions, which require regulatory approval, were carried out in April through Astor Enerji’s Romanian subsidiary Astor RO Energy.

Under the global partnership agreement, Astor will receive battery energy storage systems (BESS) for the four grid-connected photovoltaic projects in Romania, with a total storage capacity of up to 2 GWh, according to a press release from Energy Vault.

Astor Enerji, for its part, will supply transformers and high-voltage equipment for Energy Vault’s BESS projects of over 1 GW overall, planned in the United States, Australia, and Europe.

Olcay Doğan, CFO of Astor Enerji, stated that Energy Vault’s innovative approach to energy storage makes it an ideal partner to support the Turkish company’s expansion into the battery sector.

According to Energy Vault’s chief revenue officer, Marco Terruzzin, the collaboration with Astor Enerji will help build the technology and supply chain capacity to meet surging power demand from artificial intelligence (AI) data centers and the rapid adoption of renewable energy.

Energy Vault has secured USD 300 million for BESS projects around the world

Energy Vault develops and deploys utility-scale energy storage solutions, including proprietary gravity-based storage, battery storage, and green hydrogen energy storage technologies. It recently announced a USD 300 million deal with an investment fund to finance the launch of a subsidiary that will develop, build, own, and operate energy storage assets, standalone or paired with generation facilities, around the world.

Astor Enerji supplies power transformers, distribution transformers, and high-voltage to medium-voltage switchgear to markets in Europe, Africa, Asia, and the United States.
