DOE Releases Results of Pilot Project on Home Energy Use

August 3, 2011

DOE, along with CenterPoint Energy Houston Electric LLC, released survey results from a 500-participant in-home display pilot program for smart meters that began last fall. Based on surveys, 71% of customers reported that they have changed their electricity consumption behavior because of the energy use data they accessed on their in-home displays. The findings were based on a smart meter and intelligent grid technology system partially funded by a $200 million DOE Smart Grid Investment Grant.

The survey showed that 83% of respondents reported turning off lights at night or when not in the room; 51% said they adjusted the temperature on their thermostat; and 93% of respondents reported they were satisfied with their in-home display. To date, CenterPoint Energy has installed nearly 1.5 million smart meters in its 2.2-million meter system. See the DOE press release, the website, and the CenterPoint Energy smart grid Web page.
