Powering Renewable Energy with Precision and Reliability

Commonwealth’s collector station services are engineered to support the growing demands of utility-scale solar and wind energy projects. Our team delivers comprehensive design, permitting, and commissioning support for collector stations that serve as the critical link between renewable generation and the grid.


What We Do

Collector stations are the backbone of renewable energy collection systems. They gather power from multiple feeder circuits and deliver it to a substation or directly to the transmission system. Commonwealth provides:

  • Site selection and layout optimization
  • Electrical design and protection coordination
  • Civil and structural engineering
  • Arc flash and grounding studies
  • Permitting and environmental support
  • Construction support and commissioning

Whether you’re developing a 20 MW solar farm or a 300 MW wind project, our team ensures your collector station is safe, scalable, and compliant with utility interconnection standards.


Why It Matters

A well-designed collector station minimizes losses, improves reliability, and reduces construction and operational costs. Commonwealth’s designs are tailored to each project’s terrain, voltage class, and utility requirements—ensuring seamless integration and long-term performance.


Our Experience

We’ve supported collector station design and engineering across the Midwest, Texas, and the Southeast. Our team has worked with developers, EPCs, and utilities to deliver collector stations for:

  • Utility-scale solar farms (20–250 MW)
  • Wind energy projects
  • Battery energy storage systems (BESS)

Our experience includes both greenfield and retrofit projects, with a focus on fast-track schedules and evolving interconnection requirements.


Why Choose Commonwealth

  • Multidisciplinary Expertise: In-house electrical, civil, and structural teams collaborate from concept to commissioning.
  • Utility Coordination: We speak the language of utilities and help clients navigate interconnection processes with confidence.
  • Scalable Solutions: From single-feeder sites to complex multi-feeder systems, we design for today and tomorrow.


The Power of Partnership

We don’t just deliver drawings—we deliver confidence. Commonwealth partners with clients to solve challenges, meet deadlines, and build infrastructure that supports a cleaner energy future.
