The Generac Solution

Energy management today means balancing a combination of car-bon reduction, energy savings, and energy resilience goals. Gener-ac’s Stationary Battery Energy storage system (SBE) is our latest addition to a portfolio of products and technologies helping com-mercial and industrial customers to meet their current and future energy goals.

The SBE energy storage systems enable commercial and industrial customers to:

• Reduce peak demand charges and save on energy costs.

• Pair with on-site solar and lower both carbon footprint and en-ergy costs.

• Provide site resilience during brownouts/power quality issues, back up critical loads during shorter duration blackouts, and pair with our line of gas and diesel generators for full facility resil-ience during long duration blackouts.

• Earn additional revenue by monetizing the asset to support broader grid resilience.
