Sungrow and Masdar Sign 7.5GWh Storage Deal for Abu Dhabi RTC Project

Sungrow said on May 21 that it has signed an agreement with Masdar to supply 7.5GWh of PowerTitan 3.0 energy storage systems and 2.6GW of PV inverter solutions for Abu Dhabi’s round-the-clock RTC project.

The announcement adds a major procurement milestone to a project Masdar and the Emirates Water and Electricity Company describe as the world’s first gigascale 24/7 solar and battery storage scheme. EWEC says the RTC project is planned as a 5.2GW solar photovoltaic plant paired with a 19GWh battery energy storage system designed to deliver 1GW of baseload renewable power every day.

The new Sungrow deal should not be confused with the full storage scope of the project. The agreement covers 7.5GWh of storage equipment, while Masdar and EWEC continue to describe the overall RTC buildout as a 19GWh battery system.

Masdar previously said it had named preferred contractors and suppliers for the project in January 2025. The latest announcement confirms one of the main equipment suppliers for what is being positioned as a flagship renewable energy development for Abu Dhabi.

Secondary trade coverage has also reported the deal, but the clearest public terms come from Sungrow’s press release distributed through PR Newswire. The companies did not provide a fresh commercial operation date in the announcement, and background material still points to a 2027 target.

The RTC project is central to the UAE’s effort to combine large-scale solar generation with battery storage to provide continuous clean power, rather than only daytime output.
