Peak Shaving
Peak shaving is the process of reducing the demand on the electrical grid during periods of high consumption (peak demand). Vanadium Flow Batteries (VFBs) are highly effective for this application, offering a scalable and durable, long-duration energy storage solution to manage energy loads and optimize grid efficiency.
How Vanadium Flow Batteries Enable Peak Shaving
Energy Storage During Low Demand: During off-peak hours, when electricity demand is low and energy costs are lower, VFBs store surplus power from the grid or renewable sources, perfect for capturing cheap night-time rates or midday solar excess in New Zealand.
Discharging During Peak Demand: When demand spikes(typically late afternoon/evening in NZ), the stored energy is released to supplement grid supply, reducing the need for utilities to rely on expensive and less efficient peaking power plants, delivering real savings on peak demand charges.
Load Levelling: By spreading energy consumption more evenly throughout the day, VFBs help flatten the demand curve and reduce strain on the grid infrastructure, supporting grid stability and lower costs for everyone.
Benefits of Vanadium Flow Batteries for Peak Shaving
Reduces energy costs for businesses and utilities by lowering peak demand charges, often the biggest line item on commercial electricity bills.
Minimizes the risk of outages during high-demand periods by providing additional energy capacity when it’s needed most.
Decreases reliance on fossil-fuel-based peaking plants, reducing greenhouse gas emissions and supporting renewable energy integration.
Applications of Vanadium Flow Batteries for Peak Shaving
Commercial and Industrial Facilities
Reduce peak electricity demand to lower utility bills, factories, cold stores, offices, and large retailers across New Zealand are already cutting costs with commercial battery storage.
Utility-Scale Energy Storage
Support the grid by supplying energy during peak hours, improving overall efficiency and reducing the need for expensive peaker plants.
Renewable Integration
Combine with renewable sources to store excess energy and use it during high-demand periods, maximising the value of solar and wind installations.
Microgrids
In off-grid or remote locations, renewable energy systems with VFBs provide reliable energy storage and power supply, even in the absence of a centralized grid. VFBs store energy for periods of low generation and provide continuous power to off-grid communities or industrial operations.
