High electricity bills are often caused by short demand spikes, not only total energy use. Your bill may increase when the site reaches a high kW peak during the billing cycle. HVAC, compressors, pumps, motors, production equipment, or EV chargers can create one short peak that affects the whole month. Solar can reduce kWh use, but demand charges may remain when site load rises faster than solar output. Without a demand-control battery system, your site may keep pulling full peak power from the grid during high-load periods.

Short Spike, Full-Month Cost
Solar Does Not Always Stop Peaks
No Load Control
Solution
Peak Shaving Solution
Battery storage releases power during high-load periods, so your site draws less peak power from the grid.
Detect Load Spikes — Site load is monitored before demand reaches the target limit.
Discharge Battery Power — A battery energy storage system for peak shaving supplies part of the load during expensive demand periods.
Reduce Grid Demand — Energy storage lowers the highest grid draw instead of only reducing total kWh use.
Recharge at the Right Time — Charging can happen during low-load periods or from solar when solar and energy storage are used together.
System sizing should start from the equipment groups that create the same-time demand spike at your site.
Recommended Products
Choose a system based on peak load size, target kW reduction, peak duration, solar input, and site schedule. Key sizing rule: PCS kW reduces the peak. Battery kWh keeps the reduction running.

Yes, when demand charges are based on peak kW and the battery system is sized to discharge during peak load periods. Utility bill data and load profile are needed before confirming savings.
How do I know if peak shaving is worth it?
It is worth checking when your bill has demand charges, high peak kW, short load spikes, or equipment that starts at the same time.
What size battery do I need for demand reduction?
System size depends on target kW reduction, peak duration, PCS power, battery capacity, operating schedule, and whether solar charging is included. Key rule: PCS kW reduces the peak. Battery kWh keeps the reduction running.
How does peak shaving work for my site?
The battery discharges when site demand rises, reducing the peak power pulled from the grid during that period.
Can it work with solar panels?
Yes. Solar can reduce daytime energy use, while the battery discharges during high-load periods to reduce demand peaks.
What is the difference between load shifting vs peak shaving?
Load shifting moves energy use from expensive periods to cheaper periods. Demand-spike control focuses on reducing the highest demand spike that creates demand charges.
What is the difference between demand reduction vs demand response?
Site-controlled demand reduction lowers your own peak demand. Demand response usually follows a utility or grid request to reduce load during specific events.
What information do you need to calculate savings?
Savings analysis needs utility bills, demand charge rate, load profile, maximum kW demand, peak duration, operating hours, solar system size, and site electrical information.
How should I match PCS power and battery capacity?
Choose PCS kW for the target peak cut, then size battery kWh for how long that cut must last. PCS kW reduces the peak. Battery kWh keeps the reduction running through the spike window.
