EVelution Energy has begun construction of a 28 MW solar power facility that will supply renewable electricity to its planned cobalt metal and cobalt sulfate processing complex in Yuma County, Arizona. The development marks an important milestone in the expansion of the U.S. critical minerals supply chain, where clean energy is increasingly becoming a core component of industrial competitiveness.
Construction officially started with the installation of permanent steel mounting piles across the project’s 150-acre solar site. According to the company, installation of the complete solar array will continue throughout 2026 and into 2027, supporting the long-term energy requirements of the future processing facility.
Renewable Power Strengthens the Investment Case
The solar installation represents far more than a sustainability initiative. Across the critical minerals industry, access to low-carbon, reliable electricity is rapidly becoming a key factor in determining whether major processing projects attract financing and long-term customers.
Manufacturers of electric vehicle batteries, industrial consumers and governments increasingly prioritize materials that are traceable, politically secure, and produced with a lower environmental footprint. At the same time, lenders are placing greater emphasis on stable operating costs and energy security when evaluating the bankability of large industrial developments. By integrating on-site solar generation with battery energy storage, EVelution Energy is positioning its Arizona project to meet these evolving market expectations while reducing exposure to electricity price volatility.
Large-Scale Cobalt Production Planned
The planned Yuma County processing facility is expected to handle approximately 24,000 metric tonnes of cobalt hydroxide feedstock annually.
Once fully operational, the plant is designed to produce:
- Up to 20,000 tonnes per year of EV battery-grade cobalt sulfate, containing approximately 4,000 tonnes of cobalt.
- Up to 3,000 tonnes annually of alloy-grade cobalt metal.
According to the company, this production capacity could eventually supply around 40% of projected U.S. cobalt demand, making the project one of the country’s most significant planned investments in domestic battery materials processing.
Energy Infrastructure Becomes Part of the Critical Minerals Business Model
The Arizona project illustrates a broader transformation taking place across the global critical minerals sector. While access to quality feedstock and advanced refining technology remains essential, the source of electricity powering processing facilities is becoming equally important.
Governments are encouraging the development of domestic refining capacity that strengthens supply-chain security without merely shifting industrial emissions to other countries. Renewable energy projects integrated directly into mineral processing operations help achieve both objectives by lowering carbon emissions while improving energy resilience.
Execution Will Require Careful Coordination
Despite its strategic importance, the project remains a multi-year development effort involving numerous interconnected components.
The company must successfully coordinate:
- Construction of the solar power facility
- Delivery of the cobalt processing plant
- Grid connection and energy management systems
- Battery storage integration
- Feedstock logistics and supply agreements
- Plant commissioning and customer qualification
The successful execution of these elements will be critical to bringing the operation into commercial production on schedule.
Low-Carbon Power Is Emerging as a Competitive Advantage
The project demonstrates how the economics of critical minerals processing are evolving. Future competitiveness will depend not only on access to cobalt feedstock and efficient refining technology but also on the carbon intensity, reliability, and cost stability of the electricity used throughout production.
As global demand for battery materials continues to expand, projects that combine secure raw material supply, advanced processing capabilities, and renewable energy infrastructure are expected to enjoy stronger financing prospects, greater customer appeal and a more resilient position within the rapidly growing global battery supply chain.
