Trina Storage has signed its first large-scale battery energy storage agreement in Italy, partnering with renewable developer Aer Soléir on a 250MW/1000MWh project in Rondissone, near Turin.
The companies said the 1GWh scheme will rank among the largest battery energy storage systems (BESS) in Italy and Europe, marking a key milestone in their collaboration and in Trina Storage’s expansion into the Italian market.
The Rondissone project was awarded a contract under Italy’s capacity market auction for 2027 deliveries. It is expected to play a significant role in strengthening grid reliability, reducing renewable energy curtailment and supporting the country’s national decarbonisation and renewable energy targets.
Philip King, chief operating officer of Aer Soléir, said: “The team at Aer Soléir is excited to see the Rondissone BESS project reach the major milestone of signing its supply agreement with Trina Storage. Rondissone represents the first construction start in our important Italian portfolio, and we look forward to working alongside valued partners like Trina Storage.”
Under the agreement, Trina Storage will supply, deliver and commission its Elementa 2 Pro battery system. The scope includes power conversion system (PCS) units, medium-voltage skids and a power plant controller, with the project comprising 228 battery cabinets and 36 integrated PCS and MV skid enclosures.
Trina Storage will also provide a 20-year service agreement covering operations and maintenance, spare parts, 24/7 remote support, extended warranties and performance guarantees.
Gabriele Buccini, head of Trina Storage Europe, said Italy represents one of the most attractive markets for energy storage in Europe. “Italy is one of the most promising markets for energy storage, thanks to the combination of the capacity market, the MACSE programme, and the country’s accelerating renewable deployment,” he said. “This first 1GWh project in Rondissone marks the start of our long-term commitment to Italy.”
Trina Storage added that the agreement strengthens its growing European footprint, with its contracted energy storage portfolio on the continent now exceeding 4GWh.
