Abu Dhabi Future Energy Company (Masdar) in collaboration with Emirates Water and Electricity Company (EWEC) have announced the preferred suppliers and contractors for the world’s first large-scale solar PV and battery storage project in Abu Dhabi.
The project will be capable of delivering up to 1 gigawatt (GW) of baseload power 24 hours a day, seven days a week by means of a 5.2GW (DC) solar photovoltaic (PV) plant, coupled with a 19 gigawatt-hour (GWh) BESS, making it the largest solar and BESS project in the world.
Larsen & Toubro and PowerChina have been selected as the preferred engineering, procurement and construction (EPC) contractors for the project.
Jinko Solar and JA Solar are the preferred suppliers for the PV modules amounting to 2.6GW capacity each, with both companies utilizing the latest TopCon technology with optimized parameters for maximum efficiency and production for 30 years.
CATL, the preferred supplier for the battery energy storage system (BESS), will supply its TENER technology for the total capacity of 19GWh, which features all-round safety, a long service life, and a high level of integration, ensuring the reliable, stable operation and high efficiency of the entire project lifetime.


The solar PV and BESS facility will provide stability and efficiency by overcoming the intermittency of renewable energy. The 19GWh battery storage facility will enable seamless integration of solar power into the grid.
Abdulaziz Alobaidli, Chief Operating Officer, Masdar, said: “The record-breaking project we are developing with EWEC is a giant step forward in the clean energy transformation, overcoming the intermittency challenges of renewables and enabling the dispatch of clean energy 24 hours a day, seven days a week. As Masdar’s largest and most ambitious project to date, we made sure we are working with the best possible partners that will deliver to the highest standards. I look forward to working with these preferred suppliers in setting a new global benchmark in clean energy innovation.”
