This document discusses how a utility program in the Pacific Northwest transformed the grocery marketplace through using program data. It summarizes three key changes the program made: 1) targeted promotions using limited-time bonus incentives that spoke to grocers' business needs, 2) working with buying groups to increase awareness and reduce prices, and 3) partnering with manufacturers on "buy downs" to further reduce prices. These changes led to over 90% market penetration, expanded markets, and over 250 million kWh saved in the first four years. The success was attributed to building trust through credibility, reliability, intimacy, and market knowledge.
