Demand Response Presentation

Demand response is not widely used in the Pacific Northwest. That is all starting to change. The Northwest has already dipped its toes into industrial and commercial demand response demonstration projects, but the residential demonstrations have been small and simple. Dynamic load shifting and peak shaving in residential water heaters represents a significant demand response resource.

Conrad Eustis (Portland General Electric) and Phillip Kelsven (Bonneville Power Administration) will describe how a new low cost communication technology is being used to control residential water heaters for demand response. The presentation will give an overview of the technology, types of control strategies being used and for what purpose, as well as the analytics developed to measure program impacts. In this program, residential water heaters act as large batteries of stored energy in the form of hot water, heating up the water when cheap renewable power is available (load shifting) and not heating during peak periods (peak shaving). Water heaters in hundreds of homes have been equipped with a CTA 2045 communication device plugged in to their heat pump or resistance water heater tanks to receive commands. The water heater’s built in control logic (smarts) responds to events and the demand response resource depends on how much hot water is available at that moment. The goal is a demand response strategy that is cheap, flexible, and invisible to the participants.
