Energy storage plays a critical role in supporting the electric power grid by helping to balance supply and demand. Its use can prevent outages, decrease price spikes and speed the shift toward cleaner energies.
Battery technologies such as lithium-ion and metal air batteries store electricity through electrochemical reactions and convert it back to energy as needed, providing short duration services such as frequency regulation within seconds of demand.
It Can Support High Levels of Renewable Energy
Energy storage can assist renewables integration into the power grid by storing excess energy produced when it’s produced and releasing it when there is an energy shortage – this helps ensure a more balanced electricity system with lower costs for utilities and consumers alike.
Peak demand can also be decreased through energy management measures, which occur when electricity use spikes during hot summer days or evenings when people return home and switch on air conditioning units. Reducing peak demand also leads to reduced prices that could ultimately be passed along to customers.
Home and commercial energy storage systems can serve as backup power sources during extreme weather events or natural disasters, protecting homes and businesses from outages and protecting them from outages during natural disasters. Furthermore, community microgrids or resiliency hubs may help communities further away from the electricity grid who cannot rely on it; energy storage also increases access to clean energy for rural or island communities.
It Can Replace Dirty Peaker Plants
Many aging fossil-fueled peaker plants are nearing retirement age and need replacement. CESA recently published an analysis with consulting firm Strategen demonstrating battery storage can cost-effectively replace these resources in Maine, and by extension New England (including Connecticut, Massachusetts, New Hampshire, Rhode Island and Vermont).
Fossil-fueled peaker plants are expensive and inefficient power generators that produce significant greenhouse gas and health-damaging pollution when producing electricity. Furthermore, many of these facilities are located in dense urban areas designated by the state as “environmental justice communities” where residents bear an unmanageable burden due to emissions from these sources.
Energy Storage offers a cost-effective solution by pairing with natural gas turbines, enabling the turbines to only run when demand for electricity is highest, while excess energy stored in batteries provides power on demand. When coupled with such technologies as natural gas turbines, this combination allows energy storage systems to meet local air pollution, carbon dioxide and smog emissions while decreasing grid greenhouse gas emissions; meeting Clean Peak standards without incurring costly regulations from EPA is also achievable thanks to West Virginia v EPA ruling of Supreme Court of US
It Can Help Communities Avoid Blackouts
Energy storage enables new, cleaner sources of electricity to be deployed more easily and reliably by offering flexibility on the grid. Furthermore, energy storage reduces costs by eliminating investments like power lines or substations needed to make this happen.
Storage solutions deployed intelligently can increase system resiliency to avoid blackouts by providing back-up power when grid problems occur. Energy storage can even help renewables to be more consistent by absorbing excess energy during low demand times and then releasing it when there is higher demand.
Storage systems can also help customers save money by shifting load away from peak solar times and eliminating or reducing demand charges, helping homes, small businesses, and communities that pay time-of-use rates save significant sums by shifting load away from peak times – potentially eliminating or reducing demand charges altogether – leading to significant cost savings for them all. Furthermore, it helps reduce fossil fuel use and greenhouse gas emissions, promote electric vehicle adoption, heating/cooling options that support them all as well as support local jobs in many cases. Finally, storage can help communities address equity access concerns while supporting local job growth as well as supporting local jobs within them all!
It Can Help Deploy Clean Energy
Energy storage makes renewable energies like wind and solar easier to implement by smoothing their output as resources come online and offline, helping us meet decarbonization goals of the electricity system.
Rechargeable batteries store chemical energy that can be converted to electricity; hydroelectric dams use gravitational potential energy stored by water storage to drive turbines; fossil fuels store ancient energy captured by living organisms over time and buried underground, only being released back when these fossil fuels are burned to produce electricity.
Energy storage systems can help both small businesses and residential consumers avoid costly demand charges by lowering peak electricity prices and providing backup power during disruptions. Energy storage can be placed anywhere on the electricity grid: transmission network, distribution network, generator (for instance co-located with wind or solar generators) as well as commercial buildings or homes.
