Significant Price Gaps as Providers Compete to Lower Rates
The electric vehicle fast charging market is showing signs of a price war, with Ionna—a joint venture by eight automakers—and retail giant Walmart introducing rates below the market average to challenge established leaders Tesla and Electrify America. According to energy data analytics firm Paren, Ionna charges an average of $0.37 per kWh, the lowest among 17 major U.S. charging networks, while Walmart ranks fourth at $0.43 per kWh. Both are well below Tesla and Electrify America’s average of $0.56 per kWh.
For example, fully charging a 2024 Chevy Blazer EV at Electrify America costs $47.60, but the same charge at Ionna costs approximately $28.50, a savings of nearly 40%. Ionna has recently offered limited-time promotions, slashing rates to as low as $0.20 per kWh, even below the U.S. average residential electricity price of $0.18 per kWh. Walmart, meanwhile, provides a 10% discount on charging for Walmart+ members, further reducing costs for users.
Automakers Collaborate on Expansion as Ionna Targets 30,000 Chargers
Ionna, backed by BMW, General Motors, Honda, Hyundai, Kia, Mercedes-Benz, Stellantis, and Toyota, plans to deploy 30,000 fast chargers across the U.S. and Canada by 2030. The company has already begun installing charging stations at multiple locations, some of which include convenience stores and restrooms. Loren McDonald, CEO of Ionna, stated that new entrants must offer competitive pricing to disrupt the dominance of Tesla and Electrify America, as most drivers’ navigation systems default to these networks, and some automakers provide free charging credits, reducing consumers’ willingness to switch.
Walmart has partnered with Alpitronic to install 400-kW fast chargers in the parking lots of hundreds of its stores across the U.S., supporting both NACS and CCS charging standards. Walmart’s charging network has expanded rapidly, with hundreds of new chargers added in recent months. McDonald noted that Walmart’s scale allows it to secure equipment and electricity at lower costs, and its ample parking space reduces installation expenses compared to other providers. Beyond direct revenue, the chargers attract customers into stores, with each charging session generating an estimated $50 to $100 in additional sales for Walmart.
Charging Costs Still Higher Than Home Electricity as Market Competition Heats Up
Despite Ionna and Walmart’s below-average rates, their prices remain higher than the U.S. average residential electricity cost of $0.18 per kWh. Over 90% of EV charging occurs at home or work, limiting the impact of fast-charging price wars on most drivers’ daily routines. However, as Ionna and Walmart continue to expand, competition in the market is intensifying, and charging prices are expected to decline further.
Some Tesla Superchargers charge as much as $0.74 per kWh, making EV charging costs comparable to or even higher than gasoline. For instance, driving a 2024 Chevy Blazer AWD 279 miles costs about $51.61 in gasoline, while charging the same distance at a Tesla Supercharger costs up to $62.90. McDonald believes Ionna and Walmart’s aggressive pricing will force established players like Tesla and Electrify America to adjust their rates or enhance services, ultimately benefiting EV owners.
The market also includes other charging networks such as EVGo, Shell Recharge, and Rocky Mountain Power, each offering varying prices and service quality. As EV adoption grows, competition in charging infrastructure will become fiercer, providing consumers with more options and better pricing.
