Peak shaving and load shifting are common strategies in modern energy management that involve time-based energy allocation using energy storage systems to reduce electricity bills and optimize power usage.

• Peak shaving means discharging stored energy during high-demand periods to reduce grid load and peak demand charges.

• Load shifting refers to charging the ESS during off-peak hours (low electricity prices) and discharging during peak hours (high electricity prices).

These strategies are especially beneficial for industrial parks, data centers, and commercial buildings with time-of-use (TOU) tariffs or demand charges.

Challenges in Peak Shaving and Load Shifting

Despite the benefits, implementing ESS for peak shaving and load shifting can involve several challenges:

• How to analyze a facility’s energy load curve accurately

• How to size the ESS system appropriately for different scenarios

• Choosing between air-cooled and liquid-cooled systems

• Ensuring compliance with grid codes and safety certifications

Dagong ESS helps users overcome these obstacles through tailored system integration and consulting.

Frequently Asked Questions

Q1: How do I determine the ESS size needed for my facility?
A: Start by analyzing your daily energy load curve. Estimate the kWh needed to offset your peak demand. Dagong ESS provides sizing consultation based on your data.

Q2: What's the typical ROI of a peak shaving ESS?
A: Return on investment usually ranges from 2 to 5 years, depending on tariff structure, usage pattern, and ESS size.

Q3: Air-cooled or liquid-cooled ESS—which should I choose?
A: Air-cooled systems are cost-efficient and easier to maintain. Liquid-cooled systems are ideal for high-temperature or large-scale installations that demand advanced thermal control.

Q4: How long does a lithium battery ESS last?
A: Dagong ESS uses LFP battery chemistry rated for over 8000 cycles. With one full cycle per day, the expected lifespan exceeds 15 years.

Q5: How can I get a quotation?
A: Pricing varies depending on system size, cooling configuration, and site location. Contact sales@dagongess.com for EXW, FOB, or CIF offers.
