Innovation To Combat Water Scarcity And Energy Demands

The proposed installation consists of an upper reservoir, conduction pressure pipes, power station, and a structure of inlet and outlet of seawater. The plant generates power during peak hours by releasing seawater from the upper reservoir through the load pipe to the power plant, which will have one or more variable speed generating turbines. It’s these flexible, variable speed pump-turbine units that provide the quick response necessary to accommodate the fluctuating nature of solar and wind generation.

The discharged water leaves the power plant into the ocean through an underground discharge channel, which emerges on the seabed. During the recharge cycle, seawater is pumped back into the reservoir using the same reverse turbines, which generates a low-cost load (i.e., energy during non-peak hours). In addition to providing benefits in the energy area, the system can help stabilize the power and ancillary services included as programming and dispatch, reactive power, voltage control, loss compensation, load monitoring, protection of the system, and energy imbalance.
