Why is energy storage important?

Energy storage is an enabling technology, which – when paired with energy generated using renewable resources – can save consumers money, improve reliability and resilience, integrate generation sources, and help reduce environmental impacts. Explore energy storage resources Investment in energy storage created long-term reliability.

What is an energy storage system?

An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. ESSs provide a variety of services to support electric power grids.

Does energy storage save money?

Energy storage can save operational costs in powering the grid, as well as save money for electricity consumers who install energy storage in their homes and businesses.

How can electrical energy storage improve energy production?

Furthermore, in renewable energy installations like wind farms or photovoltaic systems, electrical energy storage can mitigate output variability—rapidly smoothing out the dips and spikes in power production caused by changing wind speeds or sunlight conditions.

Why do we invest in energy storage?

Our investment in energy storage evolves with our grid, creating long-term benefit and reliability for years to come. Energy storage is a critical hub for the entire grid, augmenting resources from wind, solar and hydro, to nuclear and fossil fuels, to demand side resources and system efficiency assets.

Why should you use energy storage during a power outage?

By using energy storage during brief outages, businesses can avoid costly disruptions and continue normal operations. Residents can save themselves from lost food and medicines, and the inconvenience of not having electricity.
