To achieve its objectives, Glendale enrolled its customers in Opower’s behavioral demand response (BDR) solution. The idea behind BDR is simple: that, by empowering customers with personalized insights before and after peak days, utilities can reliably motivate them to reduce peak demand. Unlike other demand response programs, BDR runs on AMI data alone — no installed devices or special prices necessary. Glendale tested Behavioral Demand Response across two customer groups: homes that were already receiving energy efficiency messaging, and homes that weren’t. The approach allowed Glendale to measure the impact of efficiency and peak solutions separately and in combination. Wisely, Glendale used the industry’s gold standard — a randomized controlled trial — to ensure accurate results.
