Snohomish County PUD

Darrington Community Microgrid

In partnership with Snohomish PUD, this team developed multiple microgrid designs that aim to reduce utility costs and provide outage support for the critical loads of the remote community of Darrington, WA. HOMER PRO and Helioscope were utilized to recommend optimized battery and solar array sizes. Additionally, design aspects were developed for a microcontroller that maintains system stability between changing operation modes and worst-case scenarios. While designs supporting existing load profiles were technically viable, their associated costs were exorbitant enough that the team also designed and recommended a full HVAC retrofit, enabling a significantly more cost-effective microgrid solution.
