Learn How SnoPUD Redefined Their Demand Response for Winter Peaking

In early 2022, Snohomish County Public Utility District (SnoPUD) concluded the first full winter of its demand response and time-dynamic rates pilot, called FlexEnergy. Read this report to learn:

  • The key differences in load shape and device types, comparing air conditioners for summer peaks and heaters for winter peaks.
  • How emphasizing customer communication and engagement first helped create a successful pilot.
  • The end program results and takeaways for iterative improvement.



“The FlexEnergy pilots demonstrate that people are willing to shift usage, even if they don’t have technology – there’s value out there.”
