Is battery storage right for your business?

Battery storage is a way to optimize energy by storing power now to use later. PG&E is here to provide helpful information on whether battery storage is right for you, answer your questions about financing and potential bill savings, and help you understand the steps to get started.

Understand the potential benefits

Some commercial customers could see bill savings or short-term backup power benefits from battery storage. Review the information below to determine if batteries are right for you.


  • Maximize your solar or renewable investment: If you have solar photovoltaic (PV), a battery may help optimize carbon reduction impacts and energy bill savings.
  • Demand charge and energy savings: Battery storage may reduce monthly demand charges for business customers by discharging the battery when you are utilizing the most energy. Also, if you are on a time-of-use rate, you can save money by charging at a time when energy is cheaper, for example in the morning, and discharging when it is more expensive, during the early evening peak period. Talk to your contractor about what you can expect to save. Learn about the Time-of-Use Rate.
  • Backup power: A battery storage system is capable of providing emergency power to a property for several hours. The duration of the power supply is dependent on overall energy use, battery size and listed capacity on the battery. PLEASE NOTE: Incentives are not available for backup-only purposes.


See Getting Started (below) and talk to a contractor about if a battery may help you save.

Battery technology performs two main functions:

  • Charging: from either your private rooftop solar system or from the PG&E grid to be stored and used at a later time.
  • Discharging: using the energy stored by the battery to either power your business or return back to the PG&E grid.

Rooftop solar panels on your property feed your storage batteries. The batteries then send power back to your property or to the PG&E grid.Opens in new Window.
  • Smart Management Software: This software is included with every battery to automate the charging and discharging process and monitor system performance to help product safety and reliability. Mobile apps are available for many batteries to help customers monitor energy. The software can be programmed to automatically charge the battery when energy is cheaper and discharge when it’s more expensive.
  • Inverter: Inverters are necessary to convert stored energy from your battery to power your business or send power back to the PG&E grid. Inverter installation is included when the battery is installed by your contractor.
  • Battery Maintenance Energy: Batteries use a small amount of energy to stay in an operational state whether or not they are being discharged. This may have a small impact on your monthly energy usage.
