Baseline data collection

SDG&E Plug Load Study

Collected the following parameters from 22 homes

Average Active/Inactive STB Power (kW)

Hours Watched per Day – Active/Inactive Hours

M&E Study

Experimental Design Found that those customers offered the upgrade offer

had upgraded their STB at an 11 times higher rate than the control group who

did not receive the same offer.

Pay TV Provider

Energy usage for non-Energy Star boxes for SD, HD, HD-DVR

Baseline methodology

Yearly Energy Consumption:

Yearly Consumption (kWh/year) = [(Average Active Power*Active Hours

Watched per Day) + (Average Inactive Power*Inactive Hours per Day)]*(365

days/year)*(1 Watt/kW)
