The electricity network is a complex system. In this grid, the power supply and demand need to be balanced every moment. For expected changes in demand, the supply needs constant adjustments. Examples of predictable changes include – storms, daily patterns of human activity, unexpected changes from equipment overloads, etc. The energy storage system has a crucial role to play in this act of balancing. It will help in creating a more flexible and reliable grid system.
The following passages can help you get a better idea of how an energy storage system works. So, keep on reading.
How an Energy Storage System Works
Sometimes, especially during the night, there is more power supply than demand. At night, the low-cost power plants continue to operate. Thus, the excess electricity is generated that can be used to power storage devices. Later on, when the demand is greater than supply; storage facilities will supply the preserved energy to the grid.
In the past decades, pumping the water back behind hydroelectric dams has been used as a form of storage. It absorbs the excess capacity from the grid and supplies it to the grid later when it is required. In the future, with the emergence of more storage technology options and when Australia transitions to a cleaner energy economy, energy storage is going to play even a more significant role.
Now, let us take a look at different ways it can benefit you.
Energy storage saves operational costs in powering the grid while saving money on electricity consumption at homes and business premises. This storage option reduces the cost of providing frequency regulation and revolving reserve services. Also, it balances the cost to consumers by storing low-cost energy and using it later. It helps a lot during peak periods at higher electricity rates or emergencies.
Improve Consistency & Flexibility
Energy storage can supply backup power at the time of disruptions. It can help an individual while it can be scaled up to meet the need of an entire building. Storage assures flexibility for the grid and ensures an uninterrupted power supply to consumers anytime, anywhere.
Incorporate Different Resources
Energy storage smoothens out the supply of adjustable or alternating resources including wind and solar. It works by preserving the excess energy when the sun is shining and the wind is blowing, and then giving the energy back when the opposite is going on.
Apart from offering all these benefits, an energy storage system also reduces environmental impacts. In other words, energy storage saves electricity for later when and where required. Thus, it enhances the electric grid efficiency by reducing greenhouse gas (GHG) emissions.
