Valuing Resilience in Solar+Storage Microgrids: A New Critical Load Tiering Approach

Tuesday, August 11, 2020 @ 1:00 PM - 2:00 PM ET

Finding an appropriate way to determine the value of resilience – keeping the lights on, essential loads powered, and critical services up and running – has been a common struggle for microgrid projects, particularly projects providing difficult to quantify community services. Based on real world experience with the design and implementation of solar+storage microgrids, the nonprofit Clean Coalition has developed a standardized and straightforward methodology for valuing resilience.

Clean Coalition’s value-of-resilience (VOR) approach applies to any type of facility and begins with tiering loads into three categories: Tier 1 (critical), Tier 2 (priority), and Tier 3 (discretionary). In this webinar, Clean Coalition Founder and Executive Director Craig Lewis covered the “VOR123” methodology and provide specific solar+storage microgrid examples. The webinar covered topics including:

  • Tiering loads
  • Valuing resilience
  • Managing energy storage for resilience and economic optimization
  • Managing loads via state-of-the-art load management solutions
  • Evaluating solar+storage microgrid economics

Clean Energy Group Vice President and Project Director Seth Mullendore moderated.
