Demand Response Event Simulator

Simulate a utility demand response event for different building types. Select DR strategies, set the event window, and see the load shape — including pre-cooling, load shed, and rebound peaks — with estimated peak demand reduction and cost savings.

METHODOLOGY NOTES

Load profiles are normalized to typical building archetypes based on DOE Commercial Reference Buildings data. Demand reductions apply during the 2-hour event window; rebound occurs 1–2 hours after the event as deferred loads resume. Pre-cooling increases load ~8% for 2 hours before the event when thermostat float is selected. Demand charge savings assume the DR-adjusted peak becomes the monthly billing demand, at the per-kW rate shown. Actual savings depend on utility tariff, measurement and verification methodology, and baseline calculation rules.
