What Is Load Shifting?
Load shifting moves electricity consumption to lower-cost off-peak periods.
Load shifting is an energy management strategy that moves electricity consumption from high-price periods to lower-price periods.
Unlike peak shaving, load shifting does not necessarily reduce total energy consumption. Instead, it changes when electricity is used.
Time-of-use electricity pricing encourages this behavior by charging different rates depending on the time of day.
Energy market analysis from the International Energy Agency shows that flexible demand strategies like load shifting play an important role in modern electricity systems.
Examples of Load Shifting
Common load shifting strategies include:
Charging electric vehicles overnight
Running industrial processes during off-peak hours
Pre-cooling commercial buildings early in the day
Scheduling data processing tasks overnight
By shifting energy usage to cheaper periods, businesses can significantly reduce electricity costs.

Peak shaving is a widely used strategy for reducing electricity demand charges in commercial and industrial facilities. Many businesses experience short periods of very high electricity demand. These spikes often increase monthly power costs.
However, companies can control these costs with peak shaving energy storage and commercial and industrial battery energy storage systems that store electricity during low-demand periods . Battery energy storage systems store electricity during periods of low demand. Later, the stored energy is released when power demand rises. As a result, the facility draws less electricity from the grid.
This approach lowers demand charges and improves energy efficiency. In addition, it helps utilities balance electricity supply and demand more effectively.
What Is Peak Shaving?
Peak shaving is an energy management strategy that reduces electricity demand during periods of high consumption. Businesses often use battery energy storage systems to store electricity during low-demand hours and release it when demand increases. As a result, facilities reduce peak power usage and lower demand charges.
According to research from the U.S. Department of Energy, battery energy storage systems can help reduce electricity demand during peak periods and improve grid stability.
What Is Peak Shaving in Energy Management
Peak shaving is an energy management technique that reduces electricity demand during high-consumption periods. Instead of drawing all electricity from the grid, a facility uses stored energy or controlled loads to limit demand spikes.
Electric utilities often charge customers based on their highest power demand during a billing cycle. Even a short increase in electricity usage can raise the total cost for the entire month.
This is where peak demand management becomes important.
For example, a factory may run several large machines at the same time. When those machines start simultaneously, electricity demand rises quickly. Without a demand reduction strategy, that spike becomes the facility’s recorded peak demand.
Battery storage can supply part of the electricity during that moment. Consequently, the power drawn from the grid decreases. The result is a lower recorded peak demand and reduced electricity charges.
Why Peak Shaving Is Important for Commercial Energy Users
Electricity pricing structures often include both energy charges and demand charges. Energy charges are based on total electricity consumption. Demand charges, however, depend on the highest power demand during the billing cycle.
Because of this structure, demand charges can represent a significant portion of a commercial electricity bill.
Peak shaving helps businesses control these costs in several ways.
Lower Electricity Costs
Peak shaving reduces the maximum electricity demand recorded by utilities. Consequently, businesses pay lower demand charges each month.
Predictable Energy Expenses

Renewable Energy Integration
Battery systems can store excess renewable electricity generated by solar or wind systems. Later, the stored energy can support peak demand.
How Peak Shaving Energy Storage Works
Battery systems are one of the most effective technologies for controlling peak electricity demand. These systems store electrical energy and release it when demand increases.
Reducing peak electricity demand can provide significant cost savings.
Utilities typically calculate demand charges based on the highest power demand recorded during the billing period.
Even a brief demand spike can increase the total monthly bill.
peak shaving load profile
Consider a simple example.
A manufacturing facility has a peak demand of 1000 kW. The utility charges $20 per kW for demand charges.
Monthly demand charge:
1000 kW × $20 = $20,000
Now assume a battery system reduces peak demand to 700 kW.
New demand charge:
700 kW × $20 = $14,000
Monthly savings:
$6,000
Over time, these savings can offset the investment in energy storage.

A Virtual Power Plant (VPP) is a digital platform that aggregates distributed energy resources (DERs)—like rooftop solar, home batteries, EV chargers, and smart appliances—and orchestrates them as if they were one large power plant.
When applied to communities, VPPs enhance resilience by:
⚡ Balancing supply and demand instantly, even during sudden surges.
🔋 Storing surplus energy in batteries and releasing it when needed.
The Central Role of Battery Energy Storage in Resilience
While renewable generation provides clean energy, it is intermittent—the sun doesn’t always shine, and the wind doesn’t always blow. Battery Energy Storage Systems (BESS) are the game-changer that unlock resilience.
Key Benefits of BESS in Resilience:
Energy Shifting – Store energy when renewable production is high and use it later.
Backup Power – Keep critical systems running during outages.
Frequency Regulation – Stabilize voltage and frequency to protect local equipment.
Decentralized Independence – Reduce reliance on fragile central grids.
Without BESS, communities cannot achieve true energy resilience. With it, they gain energy security, flexibility, and reliability.
Case Example: A Coastal Town Using VPPs for Resilience
Imagine a coastal community that faces frequent storms. Traditionally, each outage would leave residents without power for days.
Revenue Opportunities – Stored energy can be sold back to the grid or shared within the community.
Sustainability – Reduced dependence on fossil fuels lowers emissions.
Attractiveness for Investment – Resilient communities attract businesses and residents.
Peace of Mind – Security knowing that power supply is reliable, even in emergencies.
Linking Resilience to the Energy Transition
Community energy resilience aligns perfectly with the global energy transition. Instead of top-down, centralized systems, the future is:
Decentralized – Local generation and storage reduce stress on central grids.
Digital – Smart software platforms optimize resources in real-time.
Sustainable – Renewable energy replaces carbon-heavy fuels.
Participatory – Communities become active players in energy markets, not just consumers.
By adopting Virtual Power Plants, communities are not only protecting themselves—they’re contributing to the broader goal of a cleaner, smarter, and more resilient energy future.
Conclusion
As climate change and grid challenges intensify, community energy resilience is no longer optional—it’s essential. Virtual Power Plants, powered by battery energy storage and intelligent software, provide the tools communities need to thrive in uncertain times.
