Summary
- EVs can be programmed to avoid peak hours to prevent strain on the electrical grid
- EVs contribute more in utility system revenues than costs, leading to lower electricity rates for all customers
- California laws require grid upgrades to handle increased loads from EVs
- Driving an EV benefits the environment, reduces emissions, and lowers consumer costs
- EV charging brings in more revenue for utilities than it costs to serve, leading to a positive impact on electricity rates

Electric vehicles (EVs) are becoming increasingly popular as a companion to solar and wind generation in the fight against the climate crisis. The electricity grid is equipped to handle the demands of EVs, especially since there is excess capacity during non-peak hours. In fact, some EV models can even provide electricity back to the grid during peak demand, supporting the grid and preventing blackouts. While EVs only make up a small portion of overall electricity demand, concerns about overtaxing the grid still exist. However, studies have shown that EVs can actually have a positive impact on electricity rates for both EV owners and non-EV users.
The interplay between EVs and electricity rates is complex but crucial to understand. A study conducted by Synapse Energy Economics analyzed the utility system revenues and costs associated with EVs in California. They found that EVs have increased utility revenues more than they have increased costs, leading to a decrease in electricity rates for all customers. This downward pressure on rates is attributed to the additional revenue that EV charging provides to utilities, which is then distributed back to all customers through revenue decoupling. State and federal governments are also stepping in to help prepare the grid for the increase in clean energy and EVs through legislation like Assembly Bill (AB) 2700 and Senate Bill (SB) 410.
EVs not only reduce greenhouse gas emissions and support the transition to clean energy, but they also offer cost savings for consumers. Driving an EV in California can result in over 40% savings compared to driving a gasoline car. EVs have a positive impact on electricity rates for all households, regardless of whether they own an EV or not. This equity question is important to consider as the role of electric utilities in supporting the transition to EVs is determined. The reciprocity between EV drivers and electricity rates is a new reason to consider making the switch to electric transportation.
The environmental and economic benefits of EVs are significant, with zero emissions reducing air and climate pollution and reducing dependence on global oil for national security. EVs also reduce consumer costs, especially for fleets that can shift from expensive gas to lower-cost, locally-produced electricity. The future direction is clear – EVs are paving the way for safe, reliable, efficient, and clean transportation for everyday drivers. Studies and evaluations from various stakeholders predict that the downward pressure on rates provided by EVs will continue, contributing to a future where clean transportation is the norm.
