Purpose-Built for Demand Charge Control
The Peak Shaving Battery Energy Storage System is configured specifically to reduce short-duration and repeated load spikes that drive commercial and industrial demand charges. Rather than emphasizing backup duration first, this system focuses on fast response, dispatch accuracy, and continuous load monitoring so stored energy is released exactly when utility demand thresholds are at risk of being exceeded.
For many factories, logistics centers, malls, and mixed-use buildings, demand charges can account for a disproportionate share of the monthly electricity bill. A properly configured peak shaving system lowers those costs without requiring major changes to operating schedules or production routines.

Core Uses
Demand Ceiling Management
The system tracks facility load in real time and injects power when consumption approaches a predefined threshold. This allows the site to maintain a flatter demand profile and avoid expensive capacity charges.
Transformer Capacity Relief
Where transformer headroom is limited, peak shaving storage can support occasional high-load intervals and postpone expensive infrastructure upgrades.
Production Stability During Temporary Surges
Loads such as compressors, chillers, presses, elevators, and rapid EV charging can create brief surges that do not justify grid reinforcement. The system handles those intervals without changing the way the business operates.
Typical Application Scenarios
Factories with Intermittent High-Power Equipment
A facility using stamping presses or large air compressors may only hit very high demand for several minutes at a time. Even so, the utility meter records those peaks for billing. The system discharges during the spike window and recharges later when load drops, protecting the billing profile without affecting production throughput.
Commercial Buildings with Elevator and HVAC Coincidence
High-rise buildings often experience coincident peaks when elevator banks, chilled water systems, and occupancy loads overlap in the morning and late afternoon. Peak shaving storage trims those intervals and helps maintain a lower contracted demand target.
EV Charging Sites with Constrained Grid Access
At sites where a distribution upgrade would be slow or expensive, a peak shaving storage system can support high charging bursts while keeping the grid import below the available connection limit. This allows operators to launch or expand charging services faster.
Selection Guide
• Start with measured 15-minute or 30-minute interval load data if available.
• Size power first when the main goal is clipping short demand spikes.
• Size energy second based on how long the peaks usually last and how many times they occur per day.
• Reserve additional capacity if the site also expects TOU shifting or backup functionality from the same system.
