Let’s be honest: figuring out the cheapest time to charge your EV can feel like trying to game the stock market. Time-of-use plans tell you to plug in after 9pm. Unless it’s the weekend. Or a holiday. Or Mercury is in retrograde.
Enter: dynamic pricing — the new kid on the charging block that says, “what if we just told you the best time to charge… based on what the grid actually needs right now?”
Dynamic pricing uses real-time data from the grid to adjust EV charging rates hour by hour. The idea is simple: when demand is low and renewable energy is abundant, charging is cheaper. When the grid’s under stress? Prices go up. And in a state like California—where EV adoption is booming and the grid is under constant pressure—it might just be the smartest solution yet.
Need proof? The folks at ev.energy, in partnership with MCE and Silicon Valley Clean Energy, decided to test it. They launched the ChargeWise California pilot to see how real EV drivers would respond to dynamic rates.
And spoiler alert: they crushed it.
In the pilot, EV drivers delivered a whopping 98% of their charging during off-peak hours. For context, most time-of-use programs only see about 60–70% off-peak participation. Translation: dynamic pricing didn’t just work—it worked better.
This isn’t just about better habits. It’s about better savings, too.
On average, participating drivers saved $10 to $20 a month on their charging bills—without lifting a finger. The ev.energy app did all the scheduling behind the scenes, automatically shifting charging to the most cost-effective (and grid-friendly) times.
And the big picture impact? If scaled, ev.energy says this could unlock $1,000 in annual value per EV. Multiply that by millions of EVs, and now we’re talking about a serious grid game-changer.
Even more impressive? The pilot didn’t just serve early adopters with rooftop solar and perfect credit scores. Over half of the participants came from disadvantaged communities.
The team used a clever submetering approach that applied dynamic pricing only to EV charging—not to the household’s full energy bill. That made the whole thing more equitable, less risky, and way more appealing to a wider audience.
More than 1,000 customers enrolled in just two months. And they stuck with it.
The ChargeWise pilot proved that EV drivers are ready—and even excited—to charge smarter. But now utilities, regulators, and policymakers have to keep up.
Scaling dynamic pricing means updating infrastructure, smoothing out billing systems, and continuing to prioritize equity in who gets to benefit.
But if we get this right? We get a cleaner grid. We get lower costs. And we finally take the “guesswork” out of going electric.
