We are one of the nation’s leading public EV fast charging providers. With more than 1,200 fast charging stations across 47 states, we strategically deploy localized and accessible charging infrastructure by partnering with leading businesses across the U.S., including retailers, grocery stores, restaurants, shopping centers, gas stations, rideshare operators and autonomous vehicle companies.
The foundation of our business is building, owning and operating EV fast charging sites that deliver charging to EVs driven by individuals, commercial drivers and fleet operators. We prioritize the build out of high-power chargers, a key market segment that is expected to grow faster than the overall EV charging market. See "— Suppliers and Service Providers — Electricity." To take advantage of the expected growth in the number of EVs on the road in the U.S., we continue to expand our nationwide network of charging stations, focusing on development of locations with favorable traffic, utilization and financial return characteristics. Our proprietary technology and analytical tools, along with our extensive commercial partnerships with OEMs, fleets and Site Host businesses, provide a strong competitive edge as we select, design and develop new charging stations. Furthermore, our robust underwriting standards require our portfolio to meet or exceed a pre-defined internal rate of return before project approval.
Our partnerships and collaboration with a wide range of automotive OEMs, rideshare operators and other channel partners are designed to support domestic investment in transportation electrification, helping to accelerate EV adoption across the U.S. Through these partnerships, our network powered more than 1.1 billion electric miles during 2025. Total miles delivered is equal to the number of kWh we have dispensed multiplied by Vehicle Efficiency. The weighted average Vehicle Efficiency from all vehicles compatible with our network in operation at the end of each year is based on 2025 data from the DOE and S&P Global Ratings. The weighted average Vehicle Efficiency is applied to our kWh dispensed in the associated period.
We also serve the rapidly growing EV commercial segment, which focuses largely on rideshare. Reliable and flexible charging is essential to commercial electrification. We are able to deploy fleet-charging solutions for these light-duty EV fleets, and we are developing, building, operating and servicing charging assets for fleets at their own depot locations, at off-site charging hubs that we have secured, or via our expansive public network. To date, commercial contracts have either been structured as volumetric agreements or included guaranteed payment streams in exchange for guaranteed network access.
