Time-of-Use Electricity Plans for EV Owners: Maximize Savings in 2026

What Are Time-of-Use Electricity Plans and How Do They Work?

Unlike the flat-rate electricity pricing many consumers are accustomed to, Time-of-Use plans introduce a dynamic pricing model that fluctuates based on the time of day. Instead of paying a single, consistent rate per kilowatt-hour (kWh), your electricity costs are tied to distinct periods—typically on-peak and off-peak hours—each with its own price tag.

The logic behind this approach is rooted in the economics of energy generation and grid management. During late afternoons and early evenings (often between 4 PM and 9 PM), residential energy demand skyrockets. People return home, turn on air conditioning, prepare dinner, and power up various appliances. To meet this surge in demand, utilities must activate more expensive, less efficient power plants. Conversely, during the night and early morning hours, demand plummets. With less strain on the grid, utilities can rely on cheaper and often more sustainable energy sources like wind and hydroelectric power, passing these lower costs onto consumers through reduced rates.

This pricing structure creates a powerful incentive for consumers, and particularly EV owners, to shift their energy consumption to these cheaper, off-peak windows. The benefit is twofold: you save money, and you contribute to a more stable, efficient, and sustainable electrical grid. Understanding the EV Charging Speed Factors that influence your charging session can help you optimize your off-peak charging routine even further.

Typical TOU Rate Structure

• Off-peak hours: These are the golden hours for EV owners, typically spanning the evening through early morning (often 9 PM–7 AM) and extending to all day on weekends. This is when you’ll find the lowest electricity rates.
• On-peak hours: This is the period of highest demand, usually late afternoon through early evening (commonly 4 PM–9 PM) on weekdays. These hours carry the highest rates and should be avoided for heavy energy use like EV charging.
• Mid-peak hours: Some utilities offer a mid-tier option, but many are simplifying their plans to just the two main tiers for easier understanding.

For the vast majority of EV owners, this structure presents a perfect alignment. Most people naturally charge their vehicles overnight while they sleep, fitting seamlessly into the off-peak window when rates are at their lowest.

Regional Time-of-Use Rate Comparisons for 2026

It’s important to understand that TOU pricing is not a one-size-fits-all system. Rates and savings potential can vary significantly depending on where you live, reflecting local fuel mixes, infrastructure costs, and regulatory decisions. Here’s a detailed look at how TOU plans stack up across four key regions.

Portland, Oregon (Portland General Electric)

Portland currently offers one of the most aggressive TOU pricing structures in the nation, thanks to the Pacific Northwest’s abundant hydroelectric power. PGE’s rates are a dream for EV owners, with an off-peak rate of just 8.39¢/kWh compared to a steep 41.11¢/kWh during on-peak periods (5-9 PM weekdays). This staggering 80% savings potential is the highest among major U.S. utilities. To sweeten the deal, PGE also offers an additional $25 credit for customers who participate in programs that automatically pause EV charging during peak periods, adding another layer of savings on top of the already impressive rate differential.

California (Pacific Gas & Electric)

California’s electricity prices are among the highest in the country, reflecting the state’s challenges in meeting peak summer demand. However, their TOU plans still offer significant savings. PG&E’s EV2-A rate plan, designed specifically for electric vehicle owners, showcases an on-peak rate of approximately 71¢/kWh versus 36¢/kWh during off-peak hours, representing about a 49% difference. The EV2-A plan designates a highly beneficial 12 AM–3 PM window as its lowest-cost period every day, including weekends and holidays. This extended midday window is particularly advantageous for customers with solar systems, allowing them to maximize their self-generation benefits. With the off-peak rate, charging an EV is the equivalent of paying just $1.90 per gallon of gasoline, a compelling reason for any driver to make the switch.

Colorado (Xcel Energy)

Colorado implemented significant TOU rate simplifications effective October 2025, eliminating the previous “mid-peak” tier to create just two clear periods: On-peak (5-9 PM weekdays) at $0.21/kWh during summer and off-peak at $0.07/kWh. This creates a 67% savings opportunity for off-peak charging. In a notable move, Xcel made TOU rates the default plan for residential customers, meaning you must actively opt out if you prefer flat-rate pricing. Analysis by Colorado regulators indicated that most customers achieved bill savings or neutral outcomes under the new TOU structure, even without actively shifting their consumption.

East Coast (Virginia Example)

Utilities in Virginia offer more moderate but still worthwhile TOU savings. Customers in many Virginia regions can achieve nearly 50% savings by charging during off-peak hours (11 PM–6 AM), paying just 5.63¢/kWh versus 11¢/kWh during peak hours. While the savings potential isn’t as dramatic as in Portland, the consistent price difference is more than enough to justify a shift in charging habits.

The potential savings from off-peak EV charging vary by region, but the message is clear: timing matters.

Calculating Your EV Charging Savings with TOU Plans

Understanding your potential savings is straightforward with a simple calculation: Battery Capacity (kWh) × Electricity Rate ($/kWh) = Charging Cost. Most modern EVs, like the Tesla Model Y Standard Range with its 60 kWh usable battery, fall within the 60-80 kWh range.

Let’s use a practical example with our Portland EV owner. Charging a 60 kWh battery during off-peak hours at PGE’s 8.39¢/kWh rate would cost just $5.03. The same full charge during on-peak hours at 41.11¢/kWh would cost a hefty $24.67. That’s a massive $19.64 saved on a single charge.

Now, let’s extrapolate that to a typical usage pattern of three charges per week:

• Weekly savings: $19.64 × 3 = $58.92
• Monthly savings: $58.92 × 4 weeks = $235.68
• Annual savings: $235.68 × 12 = $2,828

This example clearly illustrates the potential for substantial annual savings, which in Portland alone exceeds the cost of installing a smart Level 2 charger. Even with smaller savings in other regions, the numbers are compelling. To better understand the EV Charging Efficiency of your specific setup, consider how factors like cable length and ambient temperature can affect your overall charging costs.

Maximizing Your TOU Savings: Proven Strategies

1. Install a Smart, Schedulable Charger

Standard Level 2 chargers lack the intelligence to schedule charging within a specific time window. A smart Level 2 charger with scheduling capability is an essential investment for any EV owner on a TOU plan. These chargers can be programmed to automatically initiate charging only during off-peak hours, even if your car is plugged in during the expensive peak periods. Most offer companion apps that can even integrate your utility’s TOU schedule for seamless automation. When selecting your charger, be sure to Choose the Right EV Charger that offers the smart features needed to maximize your TOU savings.

2. Leverage Extended Off-Peak Windows

Understanding the exact off-peak windows of your utility is crucial. For instance, California’s PG&E offers an exceptionally long window (12 AM–3 PM daily), allowing for convenient afternoon charging at the lowest rates. Similarly, Xcel Energy’s new Colorado rates have extended off-peak hours by two hours daily compared to the previous schedule. Knowing these windows maximizes your opportunities to charge at the cheapest possible price.

3. Combine TOU with Solar and Battery Storage

For homeowners with rooftop solar, TOU plans become dramatically more valuable. Solar generation peaks at midday, which often coincides with partial-peak or even off-peak rates in some plans. By adding a battery storage system, you can store excess solar generation during the day and then discharge it during peak hours, effectively avoiding peak-rate charges entirely. Federal tax credits now cover 30% of battery storage costs for systems 3 kWh and larger, making this an increasingly attractive strategy.

4. Explore Vehicle-to-Grid (V2G) Technology

While still in its early stages of adoption, Vehicle-to-Grid (V2G) technology is rapidly developing. This bidirectional charging capability allows EV owners to potentially earn money by supplying stored battery energy back to the grid during peak demand hours. It’s a future-forward strategy that could further transform your EV from an expense into a grid asset.

5. Adjust Household Practices During Peak Hours

Your energy savings aren’t limited to your EV. You can maximize your household’s overall TOU benefits by shifting other energy-intensive tasks, such as running dishwashers, doing laundry, and operating pool pumps, to overnight or weekend off-peak windows.

Regional Recommendations for EV Owners

• For Portland, Oregon residents: Enrolling in Portland General Electric’s TOU plan is an absolute no-brainer. With an 80% rate difference, it’s the most aggressive savings opportunity in the nation. Pair it with a smart charger scheduled for the 9 PM–7 AM off-peak window to reap the maximum benefits.
• For California residents: Use PG&E’s online tools to compare their EV2-A and EV-B rates to find the best fit. The EV2-A plan’s extended midday off-peak window is a boon for those with solar systems or who can charge during business hours.
• For Colorado residents: Since Xcel Energy’s simplified TOU structure is now the default, check to ensure you’re enrolled. The extended 20-hour off-peak window makes it easy to keep your charging costs low.
• For residents in other states: Check with your utility to see if TOU plans are available—over 50% of U.S. customers already have access. Even a 30-40% rate differential is often enough to justify the purchase of a smart charger and the simple habit of charging overnight. Be sure to review any Home EV Charger Permits that may be required before installation.

Potential Drawbacks and Considerations

While TOU plans are a clear winner for most EV owners, they aren’t a perfect fit for every household. It’s important to consider the potential downsides:

• Inflexible schedules: If your work or lifestyle requires you to charge during peak hours, your savings will diminish significantly.
• High overall energy usage: Households with high overall energy consumption might find that their on-peak usage charges offset any savings from off-peak charging.
• Limited peak/off-peak difference: In regions where the rate differential is smaller (30-40%), the savings may be less dramatic, though still worthwhile.

Always calculate your potential savings using your utility’s online comparison tools before committing to a plan. It’s also worth noting that some utilities offer additional programs like the go-e Load Management system, which can help optimize your home’s overall energy distribution and complement your TOU strategy.

Charging your EV overnight with a smart charger is the single most effective action you can take to lower your fueling costs in 2026.
