Battery Energy Storage Systems (BESS)
A Battery Energy Storage System banks electricity when it's cheap, clean, or self-generated — so your business can spend it exactly when you need it most. Get A Free Storage AssessmentWHAT IS A BATTERY ENERGY STORAGE SYSTEM?
A Battery Energy Storage System (BESS) is a bank of rechargeable batteries, together with the electronics and controls that charge it, monitor it, and discharge it safely. Think of it as a reservoir for electricity: energy flows in when it’s abundant, inexpensive, or coming off your own solar array, and flows back out the moment your building actually needs it.
1. Charge
FILL THE RESERVOIR
The system draws power from the grid during low-cost, off-peak hours, or from your solar array whenever it’s producing more than your building is using.
2. Store
HOLD IT SAFELY
Onboard controls keep every battery cell balanced, cool, and healthy while the energy waits in reserve, ready the instant it’s called on.
3. Discharge
PUT IT TO WORK
Stored power converts to usable electricity and flows into your building — during a rate spike, an outage, or simply when it makes the most financial sense.
Why Owners Are Adding Storage
WHAT A BESS DOES FOR YOUR BOTTOM LINE
Battery storage isn’t just a backup plan. For most commercial owners, it’s a direct way to lower costs, reduce risk, and get more value from energy you’re already paying for.
LOWER DEMAND CHARGES
Demand charges, which are fees based on your highest usage spike, can be a huge slice of a commercial bill. Discharge stored power during those spikes instead of pulling more from the grid.
KEEP THE LIGHTS ON
When the grid goes down, your battery keeps critical equipment, refrigeration, or operations running — quietly and with no emissions, unlike a generator.
GET MORE FROM YOUR SOLAR
Instead of exporting excess solar for a low credit, store it and use it after sundown, on cloudy days, or exactly when your building’s demand peaks.
BUY LOW, USE HIGH
Charge when electricity rates are lowest and discharge when they’re highest, so your building’s energy costs stop tracking the grid’s ups and downs.
QUALIFY FOR INCENTIVES
Federal tax credits and state utility programs can meaningfully offset the upfront cost of a system. We’ll help you find and stack what you qualify for.
BUILT TO GROW WITH YOU
Systems are modular. Add capacity later as your building’s load, your goals, or your utility’s rate structure changes.
