Water tower energy storage

How can a water tower store solar energy?

When you add a solar cell to the water tower / turbine / pump scheme, what you essentially have is a solar power system employing a water tower as an energy storage device. Such a system could store collected solar energy by pumping water up into the tower, and when the sun isn't shining, the system can still produce power from the turbine.

How much electricity does a water tower based energy storage system use?

According to Table 5, it was observed that the average daily electrical energy consumed to charge the water tower based energy storage system is equal to 3.78 (MWh). The amount of electrical energy generated in the discharge stage is calculated using Eq. (53) as 2.415 (MWh).

How does a water tower affect energy storage capacity?

It should be noted that the larger the volume of the tower tank and the height of the tower, the higher the energy storage capacity of the water tower will be. In the discharge stage of the energy storage system, water is released from the tower tank and electric energy is generated by passing through the water turbine.

How is electricity used in a water tower?

Electricity is used to pump water up a tower to create a head of water in water distribution systems. This is done by releasing water from a storage system through a turbine, converting the gravitational potential into electricity: that's a storage hydro system.

How much water can a water tower store?

The water tower can hold 20,000 to 30,000 gallons of water. With this volume, it's possible to consider using the water pressure to generate electricity by passing the water through an electric generator.

Why is water storage important?

Water storage has always been important in the production of electric energy and most probably will be in future energy power systems. It can help stabilize regional electricity grid systems, storing and regulating capacity and load following, and reduce costs through coordination with thermal plants.
