The project is expected to be the first of its kind in the region.
"This innovative project builds on DEWA's success in launching a 250MW pumped-storage hydroelectric power station in Hatta. It will make use of the existing water stored in the
"What characterises this innovative project is that only one reservoir will be constructed. Water will be pumped from the Arabian Gulf using solar-powered turbines. When energy demand increases, and production costs are high, turbines operated by the speed of waterfall from the upper reservoir will be used to generate electricity, with an immediate response to energy demand."
One key advantage of pumped-storage facilities is that they integrate with different renewable energy sources such as wind and solar power, which are non-flexible power supply options as they are affected when the wind drops or the sun is covered by clouds.
This makes pumped-storage hydropower an important source for energy storage, as water is stored when excess energy is produced, and then used when energy demand is at its highest during peak hours.
