A Community-Driven Island Microgrid
Cascadia Renewables
Learn more: A Community-Driven Island MicrogridOne of the northernmost parts of the continental U.S., Orcas Island is roughly three hours (by car and ferry) from downtown Seattle and is connected to the mainland by a single undersea transmission line. Extreme weather events and grid outages can leave locals stranded for extended periods of time.
To protect their uniquely vulnerable infrastructure, the San Juan County Emergency Management (SJCEM) agency identified the Orcas Center as a facility that could function as a resiliency hub in an emergency. The location was conveniently central and well known community gathering place. The issue, however, was that the Orcas Center did not have the energy resources required to function as an island-able microgrid system.
With a site (Orcas Center) and primary goal (energy resilience) in mind, SJCEM set out to find the right mix of distributed energy resources to achieve key performance benchmarks while staying within space and budgetary constraints.
In other words, this island facility was interested in “islanding” from the grid.
We are very pleased with the excellent service provided by Mayfield Renewables. Their expertise in designing solar PV systems, solar plus storage microgrids, and assisting with microgrid feasibility studies has been invaluable to our projects. The team’s professionalism, attention to detail, and innovative solutions have consistently exceeded expectations and has aided many of our successful grant applications. Thanks to their dedication and technical expertise, we have successfully implemented efficient and reliable energy systems that are both sustainable and cost-effective
Jon Miller
Development Director, Renewables, McKinstry
I wanted to express our heartfelt gratitude for your invaluable support on our recent tribal community project application of the Office of Clean Energy Development (OCED). The technical expertise your team contributed through mayfield's feasibility study not only brought clarity and understanding to the project's approach but also significantly elevated its presentation and credibility on paper. Your dedication and professionalism were genuinely appreciated!

We truly enjoy collaborating with Mayfield’s team because of their creativity and professionalism. The unique nature of our projects requires additional thoughtfulness, and Mayfield consistently delivers innovative, reliable designs that work seamlessly.
Keith Kueny
Energy and Resiliency Manager, Farmers Conservation Alliance
We’ve enjoyed working with Mayfield in every respect, and have done so for a long time because of the depth of knowledge they bring, their willingness to engage in conceptual design discussion, and their rapid turnaround when it’s time to do drawings. We routinely refer them to our partners because they’re not just an outsourced engineering firm; instead, they’re a reliable partner that can help avoid the many pitfalls of microgrid implementation. We’re looking forward to many successful projects with them in the very near future! Oh, and “Ask Mayfield Anything” videos are a great way to make a plane trip more productive!
Nate Mills
VP of Operations, American Microgrid Solutions
During the feasibility process for our community resilience center, the Mayfield team provided invaluable expertise and skills, and was patient and easy to work with. The quality of the feasibility study may have been the difference maker in our successful application for construction funding.
Bob Danko
Mt. Hood Towne Hall Association Board Member
Working with the Mayfield engineering team has been an awesome experience. Their team is professional, knowledgeable, and dedicated to quality. They communicate proactively and integrate seamlessly with our processes, ensuring our projects are completed on time and to the highest standards. We look forward to continuing our successful collaboration with Mayfield.
