Actions that defer and/or reduce consumption are DL shed candidates. To find candidates for demand limiting:

  • Identify any loads that might be deferred without significant impact on facility function, either during periods that you schedule or under conditions you can define.

  • If the impact on the facility of shedding one of these loads is minimal, assign a low shed priority to the load (Shed Priority 7–10).

  • If the impact of shedding one of these loads is slight but normally acceptable, assign a medium priority to the load (Shed Priority 4–6). For example, if water temperature is at least 105ºF (40ºC), the water heater can be turned off briefly with only a minor potential effect on users.

  • Review all loads to make certain their priorities are appropriate. Identify any that could be shed as a last resort to avoid utility peak demand charges. Assign a high priority to these loads (Shed Priority 1–3).
