One Energy will energizes the largest electric semi-truck charging site in U.S., located in Findlay, Ohio.

One Energy Enterprises on Friday unveiled the initial configuration and energization of its Power Island concept, a 30 megawatt (MW) electric semi-truck fleet charging site located at its first Megawatt Hub in Findlay, Ohio, that the company says demonstrates how One Energy plans to configure electric semi-truck charging infrastructure to concurrently support multiple corporate trucking fleet operators.

The Findlay Megawatt Hub is the largest constructed or publicly announced truck charging site in the U.S. in terms of available charging capacity. The site power system can accommodate up to 30 MW of charging in today’s configuration. One Energy is an industrial power company and the largest installer of on-site, behind-the-meter, wind energy in the United States. 

“From its inception, the electric semi-industry had an obvious chicken and egg problem. Truck manufacturers and fleet operators need to be able to charge at scale before they can move forward with deploying electric trucks at scale, said Jereme Kent, CEO of One Energy. "This Megawatt Hub configuration solves that problem. The power is already on-site, at the right voltage, and we can outfit and energize custom Power Island configurations with the necessary charging equipment in weeks or months, not years.”

One Energy plans to utilize a radial charging configuration to optimize overall site efficiency, allowing multiple corporate customers to customize charging operations and equipment to their specific fleet’s needs. The site currently has fully functional capacity at medium and low voltages. One Energy has developed patent-pending physical systems to optimize its radial truck charging configuration and is working with charging equipment manufacturers to be ready to deploy both multiplatform and OEM-specific charging solutions that match individual truck needs and charging rates as the trucks are sold.

A 138,000-volt transmission line serves the Findlay Megawatt Hub. One Energy’s facility has the capacity to charge 90 trucks concurrently (based on a typical 300-kW charge rate). The company expects to obtain direct access to transmission service pricing to provide some of the lowest-cost energy available in the United States. In addition, the site design allows it to host behind-the-meter renewable energy generation from wind and solar as demand at the site matures.

The Megawatt Hub by the numbers

  • 30 megawatts = 30,000 kilowatts
  • 90 x 300kW chargers concurrently or 30 x 1 MW chargers concurrently
  • 720,000 kilowatt hours a day of capacity
  • Up to 1,000 x 500kWh battery charges a day

Hydrogen Fuel Cell & BEV Survey
The following survey was sent as a link in an email cover message in February 2023 to the newsletter lists for Overdrive and CCJ. After approximately two weeks, a total of 176 owner-operators under their own authority, 113 owner-operators leased or assigned to a carrier and 82 fleet executives and 36 fleet employees from fleets with 10 or more power units had completed and submitted the questionnaire for a total of 407 qualified responses. Cross-tabulations based on respondent type are provided for each question when applicable.
