Utilities need to cover the cost of maintaining and upgrading the electrical grid, especially handling peak loads, which require larger capacity generation, transmission, and distribution systems. Energy providers charge commercial and industrial users different electric rates to encourage customers to manage and reduce their peak demand, thereby promoting more balanced and efficient use of the electrical grid.
Such demand charges are typically based on your highest level of grid use during a billing period. While these fees can greatly impact electricity expenses, EV charge point operators (CPOs) and fleets who optimize their charging operations through strategies such as peak shaving can minimize utility energy demand charges by using resources more efficiently.

Peak shaving, also known as load shedding or peak load shedding, is an energy management strategy to minimize short-term spikes in demand. Since demand charges are calculated based on the highest level of power demand (measured in kilowatts), peak shaving strategies in EV charging involve "shaving" your highest levels of electric vehicle site electricity usage to smooth energy consumption from the grid during popular periods to avoid or reduce high fees as grid operators work to balance electricity supply.
Together, peak shaving and load management help optimize electricity usage and enhance the efficiency of EV charging sites while reducing strain on the electrical grid to prevent overloads and minimize the need for additional power generation capacity. It''s a win-win for customers and grid operators alike.
Most companies tend to have main activities that demand a lot of power such as heating boilers or turning on heavy machinery. For CPOs and fleet owners, that''s charging electric vehicles. Peak shaving can help cut down the maximum power demand for EV charging during peak hours to offer a number of benefits to businesses.
Benefits of peak shaving in EV charging include:
Peak shaving can have many advantages if done well. Here are a few things to think about when developing your energy management strategy.
It''s important to start by understanding your energy consumption patterns over time and how your utility bill is affected by your load profile. Commercial and industrial businesses track consumption surges using a registered load profile, a detailed record from the local utility that shows how much electricity is used over a specific period of time. This profile is typically created with data from smart meters that record energy usage at regular intervals (such as every 15 minutes or hourly).
Then, define your business goals and determine how your site''s electricity traffic needs to change to achieve them. By analyzing your load profile, charge point operators can identify when and why these surges occur, allowing them to implement strategies like peak shaving to manage their energy use more effectively.
Investing in a battery energy storage system to contain excess energy during off-peak times can be valuable in reducing peak demand charges. Stored energy can be used during peak demand periods to power EV chargers, reducing reliance on the grid. Pairing a battery with onsite solar also allows generating and storing your own sustainable energy on-site to use for peak shaving.
Also, investing in a smart energy management system can help direct when EV chargers use power and from what source (the grid, solar, battery, etc.) to dynamically adjust charging rates based on real-time grid demand, electricity prices, and overall site goals. This helps automatically distribute the energy load to avoid peak periods while making the site less costly to operate and more profitable.
Businesses should continuously monitor their peak shaving strategies and be ready to make adjustments as needed to ensure that they are managing demand patterns and chaning grid conditions successfully.
Also, know that you don''t have to go at it alone. It can help to work with utilities and get customers on board to perfect your peak shaving practices. Communicating closely with the utility can provide valuable data and resources that can help in understanding grid conditions and getting support for implementing peak shaving measures. Likewise, educating EV customers or fleet drivers about the benefits of charging during off-peak hours and even providing incentives for doing so will encourage them to participate in load management efforts.
Energy management systems can help align your business operations with grid conditions, ensuring your on-site batteries charge before and deploy during your peak demand periods to reduce your grid consumption and avoid extra energy costs for the highest profit margins.
In fact, in some areas, homeowners are already encouraged to watch their energy usage during peak periods or face tariffs themselves in the name of grid stability. As rooftop solar and home battery systems become more common, such distributed energy resources (DERs) will encourage more consumers to participate in peak shaving too. When all these DERs are aggregating together, they can create virtual power plants that can also support the grid during peak times to increase its resilience.
While we have yet to see where regulations lead, the future of peak shaving is sure to evolve significantly with technological advancements, changing energy markets, and increasing demand for sustainable energy. For instance, as batteries become more efficient, cost-effective and energy-dense, businesses and grid operators will have more storage capacity for peak shaving. Integrating energy storage with growing renewable energy sources like solar and wind will become a more common tactic for EV charging peak shaving, reducing reliance on traditional fossil fuel power plants.
Internet of Things (IoT) and artificial intelligence (AI) will also influence energy management. Smarter grids will enable more accurate and automated peak shaving by dynamically managing energy flows and optimizing heavy equipment for real-time adjustments in light of demand and grid conditions. Meanwhile, machine learning will help predict peak demand by analyzing data and electronically adjusting energy usage, storage, and generation to mitigate it.More to ExploreCommercial EV charging
