Peak Shaving and Load Shifting with Lithium Battery Energy Storage Systems

What is Peak Shaving and Load Shifting?

Peak shaving and load shifting are two smart energy management strategies that help businesses reduce electricity bills and improve energy efficiency by using lithium battery energy storage systems (ESS).

Peak shaving refers to reducing electricity use during peak demand hours by discharging stored energy.

Load shifting involves storing energy during off-peak hours and using it later when electricity prices are higher.

These strategies are especially valuable for commercial and industrial (C&I) users facing demand charges or time-of-use (TOU) electricity pricing.

Types of ESS for Peak Shaving and Load Shifting

Cabinet-Based Lithium ESS

Capacity: 100kWh–300kWh

Ideal for commercial buildings, schools, retail stores

Containerized ESS

Capacity: 500kWh–5MWh+

Designed for factories, data centers, EV charging stations, and utilities

Hybrid PV + ESS Systems

Combines solar generation with storage

Enables renewable-powered peak shaving

Dagong ESS offers all of the above options with both air-cooled and liquid-cooled configurations.

Features of Lithium Battery ESS for Peak Management

Fast Response: Discharge within milliseconds to support real-time grid demands

High Cycle Life: 8000+ charge/discharge cycles at 70% SOH

Smart EMS Control: Automates energy shifting based on utility rates

Scalability: Modular designs from 100kWh to multi-megawatt setups

Safety-Certified: CE, UN38.3, MSDS, IEC, and 3C compliance

Remote Monitoring: Real-time data access and fault diagnostics

Applications of Peak Shaving and Load Shifting

Manufacturing Facilities: Reduce high load charges from machinery start-ups

Commercial Buildings: Lower TOU electricity costs and backup power

EV Charging Stations: Supply fast charging during grid peak hours

Renewable Energy Projects: Store solar/wind power and discharge during peak demand

Microgrids: Enhance reliability and off-grid operation

Price of Lithium ESS for Peak Shaving

Pricing is based on:

System size (100kWh to 5MWh+)

Cooling type (air-cooled vs. liquid-cooled)

Integration needs (PV, EMS, grid connection)

Air-cooled cabinets (100kWh–241kWh) are more cost-effective for mid-scale peak shaving. Liquid-cooled container systems (215kWh–5MWh) suit larger factories or EV infrastructure.

Prices are usually quoted as EXW, FOB, or CIF, depending on logistics and project location.

How to Select the Right ESS for Peak Shaving and Load Shifting?

Analyze Your Energy Usage Curve

Identify peak load hours and usage patterns

Calculate daily kWh needed for peak offset

Check Your Tariff Structure

TOU pricing or demand charges? Affects ROI and system sizing

Define System Size

Small commercial: 100–250kWh

Large industrial: 500kWh–5MWh+

Choose the Right Cooling

Air-cooled: lower cost, easier maintenance

Liquid-cooled: better thermal performance in hot/high-load environments

Ensure Certifications & Safety

Look for CE, UN38.3, MSDS, IEC compliance for grid integration and insurance approval

How Long Does a Lithium Battery ESS Last?

• A well-designed ESS with LFP battery chemistry typically offers:

8000+ cycles at 70% SOH

Lifespan of 15+ years, assuming one full cycle per day

• System longevity is influenced by:

EMS accuracy

Cooling system performance

Depth of discharge (DoD) management

Regular maintenance
