Energy storage allows us to capture and store electricity in a form that can later be retrieved for reuse, with potential uses including balancing supply and demand, improving electricity quality on an intermittent basis, supporting renewable integration initiatives and supporting integration.
Energy storage devices range from capacitors that store 1 Wh for only seconds up to grid-scale chemical compounds that store electricity over years. At present, pumped hydro ESSs are the most widely utilized form of storage.
Boosts Community Resilience
Energy storage systems that combine solar with high-capacity batteries offer a reliable, sustainable source of electricity. By charging during periods of excess renewable generation and discharging at peak demand times, these storage solutions help maximize renewable energy use while wasting less.
Renewable storage provides communities with energy independence from centralized power grids and fossil fuels, helping them weather natural disasters or economic shocks with ease. Hospitals, data centers and emergency shelters that rely on energy storage can stay operational even when their grid fails.
Aggregated energy storage programs provide utilities with an economical means to increase grid resilience and build the 21st-century electric grid. As battery costs decline, energy storage’s economics will become even more appealing for deployment at key points on the grid or as backup for key services – and ownership, leasing or power purchase agreements may all be options available to them as business models for deployment.
Helps Customers Avoid Peak Pricing
Energy storage technology can significantly lower electricity bills for industrial and commercial utility customers by helping reduce demand charges during on-peak intervals and consumption levels, through peak shaving strategies implemented through battery energy storage systems or self-consumption from embedded renewables without altering application operation.
Front-of-the-meter batteries can help reduce demand or shift it off-peak for grid balancing purposes or avoid power outages caused by extreme weather events (heat domes and storms). Energy storage also helps balance intermittent resources like solar and wind as well as optimize coal and natural gas plants.
Energy storage provides you with the tools to manage rising utility rates strategically, enabling you to better control energy use. The payback of a storage system depends on your rate structure, local policies/incentives and its performance (i.e. sized appropriately and optimized).
Helps Support Renewable Energy
Energy storage works similar to batteries in cell phones or refrigerators by storing chemical energy that can later be converted back into electricity and discharged as necessary. Energy storage allows us to maximize the value of renewable sources like solar and wind which cannot be utilized at their full potential without proper energy storage solutions.
By storing energy that could later be used to offset higher electricity rates, demand response reduces the need for costly fossil fuel power plants during peak demand hours and operational costs for utilities by providing frequency regulation and spinning reserve services, as well as customer costs through participation in residential or commercial demand response programs.
Energy storage provides valuable backup power during power outages for businesses and homes, helping to prevent costly disruptions that could cause lost sales, inventory loss and even the potential risk of life loss. Battery ESSs may be installed alongside solar PV or wind projects for added benefits.
Reduces Stress on the Grid
Energy storage helps balance supply and demand by storing electricity during times of surplus production (such as sunny afternoons) and releasing it during periods of high consumption, shifting usage patterns away from peak periods while eliminating costly power plants.
Renewable energies like solar and wind pose unique challenges to grid stability. Energy storage solutions offer one way out by helping balance out the grid second by second.
ESSs can be found throughout the electric grid – transmission networks, distribution networks and generators alike. They offer essential grid services including load shifting, frequency regulation, peak shaving and energy management.
Energy storage provides numerous advantages for communities, consumers and the economy as a whole, making a more resilient and sustainable energy future possible. DNV works closely with investors, independent power providers, utilities, project developers and communities in identifying solutions to provide these crucial grid services.
