Sungrow and Masdar Sign 7.5GWh Energy Storage System for Abu Dhabi’s World First RTC Project Photograph: (Sungrow)
UAE-based clean energy major Masdar has signed an agreement with renewable energy technology firm Sungrow for the supply of 7.5 GWh battery energy storage systems (BESS) and 2.6 GW of PV inverter solutions for what is being described as Abu Dhabi’s first gigascale round-the-clock (RTC) renewable energy project.
The project, being developed jointly by Masdar and Emirates Water and Electricity Company (EWEC), combines 5.2 GW of solar PV capacity with a massive 19 GWh BESS infrastructure aimed at delivering uninterrupted renewable power at utility scale.
Under the agreement, Sungrow will supply its PowerTitan 3.0 liquid-cooled energy storage systems along with inverter technologies for the project, which is expected to become operational in 2027.
The RTC project is designed to provide 24×7 clean power supply for industrial operations, businesses, residential communities and emerging digital infrastructure segments in the UAE.
According to Sungrow, the project will deploy more than 1,000 PowerTitan 3.0 ESS units integrated with advanced PV inverter systems to support continuous renewable energy delivery and grid stability. Each unit will operate on an 8-hour charging and 16-hour discharging cycle.
The company said the system incorporates a fully liquid-cooled Silicon Carbide Power Conversion System (SiC PCS) with a maximum efficiency of 99.3 percent and a round-trip efficiency (RTE) of 90 percent. The systems are also designed to operate in temperatures of up to 55°C without derating, making them suitable for desert operating conditions in the UAE.
The project is being positioned as one of the world’s largest integrated solar-plus-storage developments and a potential global benchmark for utility-scale round-the-clock renewable power deployment.
Sungrow stated that the project aims to address renewable intermittency challenges while enabling gigascale baseload renewable energy delivery at globally competitive tariffs.
