Why do buildings need energy storage systems?

Energy storage systems enable buildings to manage their energy consumption more dynamically, supporting grid stability and preventing blackouts. Additionally, energy storage enhances building resilience by providing a backup power source during outages, ensuring critical operations continue uninterrupted.

Are energy storage systems safe for commercial buildings?

For all of the technologies listed, as long as appropriate high voltage safety procedures are followed, energy storage systems can be a safe source of power in commercial buildings. For more information on specific technologies, please see the DOE/EPRI Electricity Storage Handbook available at:

Who should consider adding energy storage to a commercial building?

This guide is intended for anyone investigating the addition of energy storage to a single or multiple commercial buildings. This could include building energy managers, facility managers, and property managers in a variety of sectors.

How can buildings optimize energy usage?

By optimizing energy usage, buildings can store energy during low demand or high renewable generation periods and use it during peak demand times, reducing costs and minimizing grid strain.

What is energy storage?

Basics of Energy Storage Energy storage refers to resources which can serve as both electrical load by consuming power while charging and electrical generation by releasing power while discharging. Energy storage comes in a variety of forms, including mechanical (e.g., pumped hydro), thermal (e.g., ice/water), and electrochemical (e.g., batteries).

What is pumped hydro storage?

Pumped hydro storage is a well-established technology that stores energy by pumping water uphill to a reservoir during times of excess energy. When energy is needed, the water is released downhill through turbines to generate electricity. This method is highly efficient and provides large-scale energy storage, which is crucial for grid stability.
