Powersystems Group announced today that Kiewit has approved Powersystems Group and Zetrak as qualified suppliers of power transformers for consideration on future utility, industrial, and energy infrastructure projects.
The approval followed a comprehensive quality audit that evaluated manufacturing processes, production capabilities, quality management systems, operating procedures, documentation, and overall readiness to support large infrastructure projects.
This qualification represents an important milestone for Powersystems Group and Zetrak as they continue expanding their presence in the North American power transformer market. It also reflects continued investment in engineering, manufacturing, testing, inspection, quality control, and project execution.
“This approval reflects the discipline, expertise, and commitment of our entire team,” said Roberto Rosario, President of Powersystems Group. “As we expand our transformer manufacturing capabilities, our focus remains clear. We want to provide dependable equipment, transparent project communication, responsive service, and the level of quality our customers expect from a long-term transformer supplier.”
Kiewit Quality Audit Confirms Project Readiness
The Kiewit quality audit reviewed the systems and procedures used throughout the transformer manufacturing process. Areas of evaluation included production controls, supplier management, manufacturing practices, quality documentation, operational procedures, inspection processes, and readiness to support demanding project requirements.
Successful completion of the audit confirms that Powersystems Group and Zetrak met the criteria evaluated during the qualification process. The approval allows the companies to be considered for future projects that align with Kiewit requirements and customer specifications.
For utilities, EPC contractors, renewable energy developers, and industrial organizations, supplier qualification is an important part of reducing project risk. Power transformer projects require detailed engineering, controlled manufacturing, documented testing, consistent communication, and close coordination across multiple teams.
The audit reviewed production controls, supplier management, inspection procedures, quality documentation, and manufacturing readiness, giving Kiewit direct visibility into how transformer projects are managed from engineering through final testing.
Expanding Power Transformer Manufacturing Capacity
Demand for large power transformers continues to place pressure on utilities, EPC contractors, industrial facilities, and energy developers across North America. In response, Powersystems Group and Zetrak are investing in expanded transformer manufacturing capacity, engineering resources, and production efficiency.
Current manufacturing capability supports power transformers rated up to 65 MVA at 138 kV.
Power transformers currently in production include:
- Two 30 MVA substation transformers
- 25 kV primary voltage
- 4,160 V secondary voltage
A manufacturing expansion scheduled for completion during the fourth quarter of 2026 is expected to increase capability to:
- Up to 100 MVA at 138 kV
- 161 kV applications, depending on project requirements
- 230 kV applications, depending on project requirements
The expansion is intended to increase production flexibility and strengthen the companies’ ability to support a wider range of utility and energy infrastructure projects.
By expanding toward 100 MVA at 138 kV, Powersystems Group and Zetrak are positioning themselves to support customers that need large power transformers for substations, generation facilities, renewable energy projects, industrial plants, critical infrastructure, and grid modernization programs.
Supporting Utilities and EPC Contractors
Transformer procurement is now a critical path issue for many substations, renewable energy projects, and industrial expansions, where delayed equipment can affect construction sequencing, commissioning, and energization dates.
Powersystems Group and Zetrak currently report typical transformer lead times ranging from 8 to 10 months. Actual delivery schedules depend on transformer specifications, material availability, testing requirements, engineering approvals, production scheduling, and project scope.
These lead times provide customers with an additional sourcing option when traditional transformer schedules may not align with project demands.
The goal is not simply to increase production volume. The companies are focused on delivering high-quality transformer solutions while maintaining clear communication, documented quality processes, and consistent project execution.
For utility and EPC customers, that approach can help improve planning, reduce uncertainty, and keep critical infrastructure projects moving forward.
Quality Is Built Into Every Transformer
Quality is not treated as a final inspection step. It is integrated throughout the transformer manufacturing process.
The process begins with engineering review and material selection. It continues through manufacturing, assembly, testing, inspection, documentation, and final delivery.
Engineers, technicians, production specialists, quality inspectors, and project managers work together to confirm that each transformer is manufactured according to the applicable technical requirements, customer specifications, and project standards.
This coordinated approach supports consistency at every stage of production.
Quality management also depends on transparency. Customers need clear information about engineering progress, production status, testing, documentation, and delivery schedules. Powersystems Group and Zetrak remain focused on providing that visibility throughout the project.
The result is a more accountable process built around reliable equipment, clear expectations, and responsive communication.
Serving the North American Power Industry
The expansion of electrical infrastructure across North America is creating increased demand for qualified power transformer suppliers.
Utilities are upgrading substations and replacing aging equipment. Renewable energy developers are connecting new generation resources. Industrial customers are increasing capacity and improving system reliability. EPC contractors are managing complex infrastructure programs with strict technical and scheduling requirements.
Powersystems Group and Zetrak are building their capabilities around these market needs.
Their transformer solutions are intended to support:
- Electric utility projects
- Substation construction and expansion
- Renewable energy developments
- Industrial power systems
- Critical infrastructure facilities
- EPC-managed energy projects
- Grid modernization initiatives
- Transformer replacement programs
By combining expanded manufacturing capacity with engineering expertise and quality-focused execution, the companies aim to become a dependable transformer supplier for projects throughout the United States and North America.
Looking Ahead
The Kiewit supplier approval marks an important step in the continued growth of Powersystems Group and Zetrak.
Both companies remain committed to investing in their people, engineering resources, manufacturing equipment, production systems, and quality processes. These investments are intended to support the growing need for reliable power transformers across utility, renewable energy, industrial, and critical infrastructure markets.
The planned expansion toward 100 MVA at 138 kV will further strengthen the companies’ ability to respond to larger and more complex project requirements.
Powersystems Group and Zetrak will continue building long-term partnerships through quality, reliability, transparent communication, and disciplined execution.
Powersystems Group thanks its employees, customers, suppliers, and project partners whose work and trust contributed to this milestone.
Together, Powersystems Group and Zetrak are helping build the electrical infrastructure that will power the next generation of growth.
