What is a battery energy storage system?

Battery energy storage systems (BESS) stabilize the electrical grid, ensuring a steady flow of power to homes and businesses regardless of fluctuations from varied energy sources or other disruptions. However, fires at some BESS installations have caused concern in communities considering BESS as a method to support their grids.

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:

Is energy storage a viable option?

Assuming the initial analysis shows that energy storage is an economically viable option, the final decision to procure an ESS needs to be taken in the broader perspective of the business as a whole. This can include looking at issues of space, noise, and timing for system installation.

Can energy storage be used as a generator?

Energy storage can provide a cleaner, quieter alternative to conventional gas or diesel generators in case of a grid outage. However, an ESS cannot be refueled the same way as a conventional generator. As such, some facilities will only use the ESS for critical loads, integrate some form of renewable generation, or pair it with a generator.

How can lead acid batteries improve the life of a battery?

TABLE 1. COMMON COMMERCIAL TECHNOLOGIES By various combinations of adding ultracapacitor technology, doping the anode, and using bipolar plates, advanced lead acid batteries gain increased cycle life and depth of discharge, while maintaining relatively low cost.
