What is Peak Shaving and Valley Filling?

Peak shaving refers to reducing electricity demand during peak hours, while valley filling means utilizing low-demand periods to charge storage systems. Together, they optimize energy consumption and reduce costs. Energy storage systems (ESS), especially lithium iron phosphate (LFP)-based solutions, are ideal tools to achieve these strategies.

Types of ESS for Peak Shaving and Valley Filling

• Residential ESS (5–30kWh): Enables households to store solar energy during the day and use it during peak hours.

• Commercial & Industrial ESS (100–372kWh): Manages demand charges by shaving peak loads in factories, data centers, and shopping malls.

• Container ESS (3.35–5MWh): Provides large-scale peak shifting for utilities and renewable energy projects.

Features of ESS in Peak Shaving and Valley Filling

• Cost Optimization: Reduces electricity bills by avoiding peak tariffs.

• Grid Stability: Smooths demand curve, preventing blackouts.

• Renewable Integration: Stores excess solar/wind for later use.

• Scalability: From small residential systems to multi-megawatt container solutions.

Applications of Peak Shaving and Valley Filling

• Factories: 100kWh–241kWh air-cooled ESS for reducing peak demand charges.

• Shopping Centers & Office Buildings: 215kWh–372kWh liquid-cooled ESS for reliable load balancing.

• Utilities: 5MWh container ESS for grid-level demand response and renewable storage.

Price of Energy Storage Systems

The cost of energy storage systems for renewable energy integration depends on several factors, including system capacity, storage duration, battery type, control software, installation conditions, and auxiliary equipment.
Pricing is usually quoted under international trade terms such as EXW, FOB, or CIF, depending on project location and logistics preferences.
For a tailored quotation based on your specific project needs, it’s best to consult directly with the supplier.

How to Select ESS for Peak Shaving and Valley Filling?

• Scale of Operation: Residential vs. industrial vs. utility.

• Battery Technology: LFP is recommended due to long cycle life.

• Software Compatibility: Ensure EMS supports time-of-use optimization.

How Long Do ESS Last in Peak Shaving Applications?

LFP-based ESS usually last 10–15 years with over 8000 charge/discharge cycles, making them ideal for daily shifting.
