2010 Energy Conservation Evaluation of Pacific Gas & Electric Company's Energy Alerts and Customer Web Presentment Programs

Pacific Gas & Electric Company’s (PG&E) Energy Alerts and Customer Web Presentment (CWP) are two informational energy conservation programs for residential customers that were first marketed in 2010. The program allows customers to have advance warning via email, phone or text message if their electricity usage is projected to push them into higher pricing tiers by the end of the current billing cycle. Energy Alerts are also sent out when the customer’s usage has actually entered any of the higher pricing tiers.

As of the end of December 2010, there were 1.4 million customers with current account numbers in the My Account program, of which 1.1 million had SmartMeter™ meters. Of these, about 128,000 logged in to CWP at least once in 2010.

This is the first evaluation of these programs. Statistical matching strategies were employed to select control groups for use in evaluating the energy conservation impacts of these programs.

The estimated conservation effects for both programs for 2010 are zero. However, there is significant uncertainty in these estimates, so it is possible that the programs could affect usage by 1-2% in either direction.
