As you’re probably aware, energy storage systems (like those here at Wattstor™) bank excess renewable energy in a battery rather than being fed back to the grid. In conditions such as reduced sunlight and storm power outages, stored energy is able to be used freely as hot water, lighting and appliances without the need of constant generation.
As the usage of renewable energy rises, so do the advancements in technologies supporting it. Tesla are currently in the build of the largest lithium-ion storage facility, storing 80 megawatts (the equivalent of powering 2,500 houses per day), increasing electricity grid reliability, taking away charges from off-peak hours and delivering energy during peak hours (see the project due to be completed by the end of 2016 here). The latest energy storage reports show hundreds of million dollars savings to be had when investing in renewable energy storage with reduced CO2 emissions and cutting peak demand impacts.
“Adding energy storage to the Commonweath’s portfolio of energy resources will not only lead to lower energy prices for ratepayers but will help create new, high-paying jobs in a growing field.” Lieutenant Governor Karyn Polito
“Increased energy storage capacity will not only lower our state’s peak demand but increase overall energy system efficiency, leading to lower carbon dioxide emissions.” Energy and Environmental Affairs Secretary Matthew Beaton
Energy storage systems can make a more efficient electricity grid. As a fast and flexible resource, the system responds quickly to variable generation outputs and in the process, reduces wear and tear on traditional generation infrastructures, meaning less fossil fuel consumption and associated greenhouse emissions.
With advantages in battery and air technologies, energy storage allows renewables to store and discharge as needed, meaning there is no purchasing or generating more expensive energy at high demand times
In short, energy storage allows for lower costs for ratepayers, increased efficiency of renewable energies and an allowance to combat climate change – don’t let that clean energy go to waste!
