Japan-based battery developer NGK Insulators has supplied sodium-sulfur (NaS) batteries for a pilot energy storage project in the United Arab Emirates.

The 1.2MW/7.2MWh batteries were supplied to Dubai’s Electricity and Water Authority (DEWA) for the project at the Mohammed Bin Rashid Al Maktoum Solar Park (MBRAMSP). Ingeteam provided power and control electronics for the battery storage facility.

The NaS system will be used for “energy time shifting, frequency control and voltage control”, as well as to increase grid stability and reduce CO2 emissions. It will be “the first energy storage system paired with a solar PV plant at a grid-scale level in the United Arab Emirates”, the companies said.
