One Energy, an industrial power company and installer of on-site, behind-the-meter, wind energy, said it is "throwing down a gauntlet to jumpstart the electric semi-industry" with a 30-megawatt electric truck charging hub in Ohio.

According to One Energy, its “Power Island” concept at its first megawatt hub in Findlay, Ohio., demonstrates how it plans to configure electric semi-truck charging infrastructure to support multiple trucking fleet operators.

The Findlay Megawatt Hub is the largest constructed or publicly announced truck charging site in the United States in terms of available charging capacity, the company said in a press release.

The site power system can accommodate up to 30 MW of charging in today’s configuration.

A Radial Charging Configuration

One Energy plans to use 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.

“From its inception, the electric semi-industry had an obvious chicken and egg problem,” said Jereme Kent, CEO, One Energy. “Truck manufacturers and fleet operators need to be able to charge at scale before they can move forward with deploying electric trucks at scale.

"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 said it designed the Findlay site to solve that problem by delivering charger-ready power at scale. 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.

Dana Saucier, head of Economic Development for JobsOhio, said, “Our state boasts some of the most competitive power costs in the world and a robust high-voltage transmission infrastructure. Unlike some states, we don't need to wait years or rely on mandates and subsidies to advance the electrification of logistics. This site is a testament to that fact. Simply put, Ohio is fast becoming the Silicon Valley of energy innovation."

A Privately Funded Venture

The Findlay Megawatt Hub was built by One Energy with its own capital and without government subsidies or grants. One Energy received no utility incentives for the site.

“Capital markets are good at building the second and third projects after the pilot has proven successful, but they have always struggled with underwriting the first one," explained Thomas Lause, CFO of One Energy. "Because we are confident in the solution and the technology, we decided not to wait. We just built it. Now we have a functioning site to show capital markets.”

Kent added, "We have already built full-scale, cost-effective charging that can serve multiple end-users. We have done it in the manufacturing center of the United States, where there are numerous local and regional truck routes. Now we are excited to see the electric semi manufacturers deliver.”
