What Is Peak Shaving and Valley Filling?
Peak shaving and valley filling are power management strategies that optimize energy use by shifting electricity consumption from peak hours to off-peak hours. By storing energy when electricity prices are low and releasing it when demand surges, businesses and households can significantly reduce their electricity bills and improve overall energy efficiency. These strategies are especially effective when combined with smart energy storage systems (ESS).
Best Solutions: Energy Storage Systems for Load Optimization
Energy storage systems are at the core of peak shaving and valley filling applications. Among various technologies, Lithium Iron Phosphate (LFP) battery systems have become the most preferred option due to their excellent safety, cycle life, and performance in different environments.
Dagong ESS offers a comprehensive range of energy storage solutions that support peak demand management for both residential and commercial use. Their systems are available in air-cooled and liquid-cooled designs, fully adaptable to the demands of different load scenarios and grid conditions.
Why Energy Storage for Peak Load Management?
Lower Electricity Costs
Store cheap energy during low-demand hours and use it when prices spike.
Reduce Demand Charges
Especially valuable for commercial and industrial users with high power consumption during peak times.
Improve Grid Independence
Store solar or wind energy and use it during peak grid periods, minimizing grid dependency.
Stabilize Power Supply
Balance intermittent loads and reduce sudden spikes that can damage equipment.
Environmentally Friendly
Facilitates better integration of renewable energy, lowering carbon emissions.
Typical Use Cases of Peak Shaving ESS
Factories and Warehouses
Manage power-intensive machinery with stored energy during startup hours.
Office Buildings and Data Centers
Avoid high TOU (time-of-use) charges while ensuring uninterrupted operations.
EV Charging Stations
Balance charging load and prevent excessive grid draw during peak charging hours.
Solar + Storage Homes
Maximize solar self-consumption by storing surplus energy and discharging it at night.
How Much Does a Peak Shaving ESS Cost?
The investment in a peak load energy storage solution varies based on capacity (kWh), control software, cooling method, and installation location. A standard system for commercial use typically ranges from $50,000 to $300,000, depending on design and battery scale. For residential setups, prices are lower, usually starting around $5,000.
Costs are typically quoted according to international terms such as EXW, FOB, or CIF. If you’re interested in a tailored solution, you can consult Dagong ESS directly for a quotation.
