Sungrow and Masdar announced the signing of an agreement for the supply of energy storage systems and photovoltaic inverter solutions for the UAE’s world-first gigascale round-the-clock renewable energy project in Abu Dhabi.
Developed by Masdar and Emirates Water and Electricity Company, the RTC project combines 5.2 GW of solar photovoltaic capacity with a 19 GWh battery energy storage system, delivering baseload renewable energy at a massive scale.
Under the agreement, Sungrow will supply 7.5 GWh of PowerTitan 3.0 energy storage systems alongside 2.6 GW of PV inverter solutions to support the project’s operational reliability and efficiency.
The project is designed to help meet growing demand for uninterrupted clean power across energy-intensive industries, business operations, residential communities, and emerging digital infrastructure.
RTC is expected to become operational in 2027 and aims to support the delivery of reliable clean energy around the clock while enhancing grid resilience and flexibility.
The project will deploy more than 1,000 PowerTitan 3.0 liquid-cooled energy storage systems integrated with advanced PV inverter technologies to support continuous power delivery and enhanced grid stability.
According to the companies, each system operates on an optimized cycle of 8-hour charging and 16-hour discharging to support a stable and flexible renewable energy supply. The systems feature an AC block design and rack-level management intended to improve operational safety and efficiency.
The system incorporates a fully liquid-cooled Silicon Carbide Power Conversion System, achieving a maximum efficiency of 99.3% and a system round-trip efficiency of 90%.
Designed for demanding climates, the system can operate at temperatures of up to 55 degrees Celsius without derating, making it suitable for UAE environmental conditions.
Sungrow said the RTC project is intended to serve as a blueprint for renewable energy infrastructure projects globally by demonstrating how solar photovoltaic and battery storage technologies can deliver gigascale baseload renewable energy at competitive tariffs.
