Trina Storage has commissioned its first utility storage project in Italy, Torre di Pierri. The system is developed and owned by Trinasolar’s International System Business Unit, its global project development arm, and has seen the two business units collaborate on the site.
Located in Avetrana in the Province of Taranto, Italy, Torre di Pierri is a 9.3 MWh standalone system that supports grid stability and arbitrage. Trina Storage was contracted by Trinasolar ISBU for the provision of the battery energy storage system, representing the first time the former has delivered a utility-scale energy storage project in Italy.
While Trinasolar ISBU owns and operates the Torre di Pierri facility, it has a contract with Terna, the Italian transmission system operator, to deliver its services for up to 1000 annual operation hours as a Fast Reserve, contributing to grid stability. Extra capacity will be 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 aimed at improving the stability of grid frequency while leaving asset owners margins for arbitrage. Trina Storage’s system underwent rigorous testing by Terna and E-Distribuzione, the distribution system operator, before going live.
