Price- and Load-Responsive CTA-2045 Controls for HPWHs

The hot water industry’s recent adoption of communication capabilities and the CTA-2045 protocol enable grid operators to perform load shifting with HPWHs. LBNL has developed an algorithm that generates a cost-reducing CTA-2045 command schedule in response to different a) groups of occupant behavior profiles, and b) price structures (e.g. PG&E rates, SCE rates, CalFlexHub’s highly dynamic prices).
