Swedish renewable energy developer OX2 has signed a framework agreement with Trina Storage, the energy storage division of Chinese solar photovoltaic (PV) products manufacturer Trinasolar, for the supply of 3 GWh of battery energy storage systems (BESS).
The agreement will support OX2’s expanding energy storage portfolio across Europe, with projects planned in Finland, Sweden, Poland, and Italy.
Owned by EQT, OX2 plans to install the battery storage systems at projects expected to reach financial close in 2026 and 2027. Most of these projects are scheduled to begin commercial operations in 2028.
Commenting on the agreement, OX2 Chief Operating Officer Paolo Romanacci said that the company’s energy storage business continues to expand through both standalone projects and hybrid solutions. He also welcomed the partnership with Trina Solar, describing the company as a long-term partner that will help OX2 deliver its ambitious project pipeline across Europe.
The latest agreement follows an earlier announcement in July, when Trina Storage confirmed that it would supply a battery energy storage system to OX2 for a 50-MW/209-MWh project in Sweden.
That project represents the third battery storage contract awarded by OX2 to Trina Storage, further strengthening the business relationship between the two companies.
With the new 3-GWh framework agreement, OX2 is continuing to expand its battery storage development activities across several European markets.
