Trina Storage has commissioned its first utility energy storage project in Italy.
The Torre di Pierri battery energy storage system (BESS) has been developed and is owned by Trinasolar International System Business Unit (ISBU), the global project development arm of the company.
Located in Avetrana in the Province of Taranto, Italy, Torre di Pierri is a 9.3MWh standalone system that supports grid stability and arbitrage.
Trina Storage was contracted by Trinasolar ISBU for the provision of the battery energy storage system.
Head of utility storage at Trina Storage Gabriele Buccini said: “Commissioning our first utility storage system in Italy is a significant milestone for Trina Storage and the wider Trinasolar group.
“Trinasolar is an integrated provider of renewable energy solutions, and Trina Storage and Trinasolar ISBU are proud to have worked together to connect the company’s first system to the Italian grid. The experience gained from this will stand us in good stead for the future.
“Looking ahead, our vertically integrated BESS solutions, namely the Elementa 2 system featuring our proprietary battery cell technology, show a huge potential for the Italian market in the coming years.”
While Trinasolar ISBU owns and operates the Torre di Pierri facility, it has a contract with the Italian transmission system operator Terna to deliver its services for up to 1000 annual operation hours as a Fast Reserve contributing to grid stability.
Extra capacity is used by Trinasolar ISBU to reduce the price differences in the electricity market.
The contract was a result of Terna’s “Fast Reserve” tender, a grid balancing service in Italy that improves the stability of grid frequency while leaving asset owners margins for arbitrage.
Trina Storage’s system underwent testing by Terna and E-Distribuzione, the distribution system operator, before going live.
