Peak Shaving Battery Systems
LiFePO4 battery energy storage systems that discharge during your highest-demand intervals — flattening load peaks and cutting the demand charges that dominate commercial and industrial electric bills.
Turn Peak Demand Into Savings
Demand charges — billed on your single highest power draw each month — can account for 30–70% of a commercial or industrial electric bill. A peak shaving battery system stores low-cost, off-peak energy and discharges it precisely when your load spikes, capping the metered demand and slashing those charges.
ChargeX peak shaving systems run on lithium iron phosphate (LiFePO4). Because peak shaving cycles the battery every day, cycle life is what makes or breaks the economics — and LiFePO4’s 6,000+ cycles with minimal degradation deliver a durable, 15–20 year asset with the safest thermal profile in mainstream lithium.
Intelligent controls monitor your load in real time and dispatch automatically to hold demand below your target threshold. The same system can stack time-of-use arbitrage, on-site solar self-consumption, backup power, and demand-response revenue for a faster payback.

Frequently Asked Questions
What is a peak shaving battery system?
A peak shaving battery system is a battery energy storage system (BESS) that discharges during a facility’s highest-demand periods to reduce the peak power drawn from the grid. By flattening those spikes, it lowers demand charges — often the largest, most volatile line item on a commercial or industrial electric bill.
How does peak shaving reduce electricity costs?
Utilities bill large customers partly on their single highest 15- or 30-minute demand interval each month. A battery charged during off-peak hours and discharged during those peaks caps the metered demand, cutting demand charges. Many sites also stack time-of-use energy arbitrage and demand-response revenue on top of the demand savings.
What size battery do I need for peak shaving?
Sizing depends on the height and duration of your demand peaks and your load profile. A typical commercial system targets the delta between average and peak demand for the hours the peak persists. Share your interval meter data and our engineering team will size the LiFePO4 system and model payback.
Why use LiFePO4 for peak shaving?
Peak shaving cycles a battery daily, so cycle life dominates economics. LiFePO4 delivers 6,000+ cycles with minimal degradation and the safest thermal profile of mainstream lithium chemistries — ideal for a daily-cycling asset expected to last 15–20 years.
Can peak shaving be combined with solar or backup power?
Yes. The same BESS can pair with on-site solar for self-consumption, provide backup power during outages, and participate in demand-response programs — maximizing the return on a single installation.
