Peak Shaving and Valley Filling with Energy Storage Systems

What is Peak Shaving and Valley Filling?

Peak shaving and valley filling refer to energy management strategies that balance electricity supply and demand by storing energy during periods of low demand (valley) and releasing it during peak demand times. This approach reduces electricity costs, alleviates grid pressure, and improves energy efficiency. Energy storage systems (ESS) play a critical role in implementing these strategies across residential, commercial, and industrial sectors.

Types of Energy Storage Systems for Peak Shaving and Valley Filling

• Battery Energy Storage Systems (BESS)
  Most commonly using lithium iron phosphate (LFP) batteries due to their safety, long life, and efficiency.

• Thermal Energy Storage
  Stores excess energy in the form of heat or cold, used mainly in HVAC or industrial applications.

• Pumped Hydro Storage
  Large-scale systems used for grid-level balancing, typically not suitable for distributed users.

• Flywheel and Supercapacitor Systems
  Provide rapid response but are mainly used for short-duration balancing.

Features of Peak Shaving & Valley Filling ESS

• Smart Load Management
  Automated control systems manage charging and discharging based on time-of-use tariffs and load profiles.

• Cost Savings
  Reduces demand charges and avoids high peak-time electricity rates.

• Grid Stabilization
  Helps maintain voltage and frequency stability by reducing sudden demand surges.

• Modular and Scalable
  Systems can be customized to match the energy profile of residential users or large-scale facilities.

• Real-time Monitoring
  Advanced ESS comes equipped with monitoring platforms to track system performance and savings.

Applications of Peak Shaving and Valley Filling

• Commercial Buildings and Factories
  Manage large electrical loads by shaving peaks to reduce demand charges.

• Data Centers
  Ensure stable power supply and optimize energy costs.

• Residential Communities
  Paired with solar PV to optimize self-consumption and lower grid dependency.

• EV Charging Stations
  Prevent power spikes by drawing energy from ESS instead of the grid during charging peaks.

• Renewable Energy Integration
  Store excess solar or wind energy during low demand and supply it during high demand.

Price of Peak Shaving & Valley Filling Systems

The cost of a peak shaving and valley filling ESS solution varies depending on system capacity, application scale, battery type, control software, and installation complexity. Prices are typically quoted based on international trade terms such as EXW, FOB, or CIF, depending on project location and logistics preferences.

For a precise quotation tailored to your project requirements, please contact the supplier directly.

How to Select the Right System for Your Project?

• Evaluate Load Profile: Understand your electricity usage pattern to size the system appropriately.

• Define Goals: Prioritize whether your goal is to save cost, enhance stability, or enable renewable integration.

• Choose the Battery Type: LFP batteries are ideal for most use cases due to longevity and safety.

• Check Compatibility: Ensure the ESS integrates well with your current electrical system or solar PV setup.

• Consult Experts: Professional suppliers can offer custom system design, installation, and after-sales support.

How Long Does the System Last?

High-quality lithium iron phosphate (LFP) energy storage systems typically last 10–15 years with over 6000 cycles, depending on operating conditions and usage frequency. Regular maintenance and optimized charge/discharge strategies can further extend lifespan.
