Sungrow and Masdar have signed a supply agreement for the UAE’s first gigawatt-scale round-the-clock renewable energy scheme, named RTC. The project, being developed by Masdar together with the Emirates Water and Electricity Company, will pair 5.2 GW of solar photovoltaic capacity with a 19 GWh battery energy storage system to provide continuous renewable baseload power.

Under the deal, Sungrow is set to deliver 7.5 GWh of its PowerTitan 3.0 energy storage systems alongside 2.6 GW of photovoltaic inverter solutions. More than 1,000 liquid-cooled PowerTitan 3.0 units will run on an 8-hour charge and 16-hour discharge cycle, supplying steady and flexible electricity to industrial plants, commercial facilities, residential communities and digital infrastructure. Each system employs an AC block design with rack-level management, boosting both safety and operational efficiency.

The PowerTitan 3.0 incorporates a fully liquid-cooled silicon carbide power conversion system, reaching a maximum efficiency of 99.3 percent and a round-trip efficiency of 90 percent. Engineered for extreme conditions, the units can function at temperatures as high as 55 °C without derating, making them especially suited to Abu Dhabi’s climate.

Slated to begin operations in 2027, the RTC project is expected to deliver reliable clean energy around the clock, enhancing grid resilience and flexibility while establishing a new benchmark for utility-scale renewable integration. By tackling solar intermittency and supplying gigascale baseload power at competitive tariffs, RTC is intended to serve as a replicable model for similar developments across the globe.
