CALSTART and Partners Selected for $44 Million Grant
to Fund Portable Off-road Worksite Energy Resource Hub

Pasadena, CA – CALSTART, a global clean-transportation industry organization, has been selected as a grant recipient for its project The California Advanced Technology Portable Off-road Worksite Energy Resource (POWER) Hub as part of the Advanced Technology Demonstration and Pilot Projects (ATDPP) grant solicitation released by the California Air Resources Board (CARB) and the California Energy Commission (CEC). The objective of the grant solicitation was to help fund the purchase and demonstration of innovative and economically viable technologies in the commercial marketplace that include zero-emission aviation, locomotive, and marine vehicles as well as off-road and green zone vehicles.

The project aims to create an off-road worksite energy hub to address challenges associated with powering zero-exhaust emissions off-road equipment in remote and off-grid locations. Use of mobile energy storage and charging systems for off-road worksites, stationary charging solutions for electric machinery and vehicles, and a solar-powered microgrid with fixed-battery energy storage systems will support renewable energy time-shifts. The project will bring health, environmental, and economic benefits to underserved communities in California, with an emphasis on workforce training and development.

Over a useful life of 10 years, the project is projected to reduce at least 6,880 metric tons of CO2e and 9.3 tons of criteria pollutants. Long term, the project is expected to exceed these emissions reductions by a significant margin through renewable energy generation and storage, and the introduction of additional electric construction machines.

“Our project pioneers an off-road worksite energy hub, revolutionizing zero-emission equipment deployment in challenging heavy-duty applications,” said John Boesel, President and CEO, CALSTART. “Through mobile storage, stationary charging, and solar microgrid innovation, we’re shifting toward sustainable solutions. This initiative isn’t just about clean power—it’s about empowerment, environmental stewardship, and economic growth, fueled by a commitment to workforce training and development.”

The California Advanced Technology POWER Hub project is a joint effort with several select industry leaders including Caterpillar Inc., Moxion Power, DANNAR, Sacramento Municipal Utility District, Burns & McDonnell, Sacramento County, Sacramento Air Quality Management District, Teichert, Holt of California, Aura Planning, Community Resource Project, Bruns Auri, Inc., Sacramento Clean Cities, California Mobility Center, Delta College, Capitol College and Career Academy, and Green Technical Education and Training.

CALSTART and partners are proposed to receive over $44 million from the grant for this project, while the project partners will provide an additional $44 million in cost share. The project seeks to showcase a holistic approach toward addressing community needs while fostering workforce development and training opportunities.

“From idea inception, the Sacramento Metropolitan Air Quality Management District has been a strong proponent of POWER Hub, a cutting-edge development project to advance clean, zero-carbon construction equipment in an innovative hub-and-spoke deployment strategy with direct benefits to our regional air quality and communities. This project is also a successful demonstration of the power of partnerships and how to align public and private technology and policy leaders toward the common goals of industrial decarbonization. The Sacramento region is an ecosystem poised to lead in these types of efforts in support of California’s leading climate agenda,” said Dr. Alberto Ayala, Executive Director of the Sacramento Metropolitan Air Quality Management District.

“CALSTART’s California Advanced Technology POWER Hub project represents a significant step toward addressing the challenges of powering zero-emission off-road equipment,” stated Moxion Power CEO, Paul Huelskamp. “As a key partner, Moxion Power is committed to delivering practical and effective mobile energy solutions that will help bridge current grid constraints and drive the adoption of zero-emission technologies. We are proud to collaborate alongside the CEC, CARB, CALSTART, and other industry leaders to contribute to the success of this groundbreaking initiative.”

Roles for the project are as follows:

  • CALSTART will work as the project lead and grant administrator.
  • Caterpillar will work as the key technology provider.
  • Sacramento Municipal Utility District will provide grid connection and energy to the project.
  • Burns & McDonnell will design and engineer the Hub’s infrastructure.
  • Sacramento County will be an end user of electric machinery at job sites.
  • The Sacramento Metropolitan Air Quality Management District will engage, involve, and integrate community and stakeholder input while supporting education and workforce pathways. The Air District will also play a critical role in advancing zero-emission policy while demonstrating innovative heavy-duty zero-emission technology and independent power storage solutions.
  • Moxion Power and DANNAR will provide mobile energy solutions.
  • Teichert will support the Hub’s construction and deployment of electric machines.
  • Aura Planning will coordinate the community benefits and workforce development program.
