Longi signs agreement with RWE to deliver 300 MWh battery storage for a solar plant in Italy
Type: Supply Agreement · Technology: Storage · Country: Italy · Capacity: 300 MWh · Announced: 2026-07-22
Longi signed a supply agreement with German energy group RWE to provide a 300 MWh battery energy storage system for a photovoltaic plant in Italy. The contract specifies the use of LongiBank 6.25 MWh LFP liquid‑cooled modules, each housed in a 20‑foot container, delivering up to 146 Wh/L energy density. The storage solution will operate in a four‑hour configuration to meet Italy's grid peak‑shaving and ancillary service requirements under the national energy‑climate plan. By coupling high‑efficiency solar generation with intelligent storage, the deal illustrates Longi's shift from pure panel manufacturing to integrated renewable‑plus‑storage projects. The agreement underscores RWE's strategy to expand its Italian renewable portfolio with flexible, dispatchable assets.
