Storage system built at world’s biggest solar park

An energy storage system has been installed at the largest single-site solar park in the world.

The battery storage facility has been built at the Mohammed Bin Rashid Al Maktoum Solar Park in Dubai and marks the first storage system to be twinned with a PV plant at a grid-scale level in the United Arab Emirates.

NGK Insulators supplied the batteries and electrical engineering company Ingeteam was responsible for the supply of a 1.2 MW power conversion system with its medium voltage components, plus the power plant controller.

UAE utility Dubai Electricity & Water Authority (DEWA) want to trial the storage system to evaluate its effectiveness in stabilizing grid fluctuations caused by intermittency of renewables.

The storage system will be also used for energy time shifting, frequency control and voltage control by using the large capacity of the batteries.

The solar park is being built in phases, has a planned capacity of 1000 MW by 2020 and 5000 MW by 2030 and will use both photovoltaic and concentrated solar technologies.

The 13 MW first phase became operational in 2013 using PV panels, with a 200 MW second phase launched in March 2017. A further 800 MW of PV will be online by 2020.

The fourth phase of the solar park will be a concentrated solar park and will feature the tallest solar tower in the world at 260 metres.
