(c) In reference to the above statements, please indicate the proportion of SoCalGas and SDG&E customers who live in newer energy efficient homes. Please provide the basis to support your response. (d) In reference to the above statements, please indicate the proportion of SoCalGas and SDG&E customers who live in cooler environments inland. Please provide the basis to support your response. (e) In reference to the statements, please indicate the proportion of SoCalGas and SDG&E customers who live in more temperate environments along the coast. (f) In reference to the above statements, do SoCalGas and SDG&E assert that intra-class subsidy currently exists? If so, then please provide the estimated intra-class cross subsidy with respect to both SoCalGas and SDG&E. RESPONSE 7: Mr. Bonnett’s testimony was intended to be a general statement regarding the potential inequities of a residential customer’s geographic location and age of their home. As an example, the two tables below show the 5-year history comparing annual heating degree days (HDDs) for the vs service areas. HDDs drive the gas heating “Inland” “Coastal” demand during cold days in winter months. Specifically, an HDD is the number of degrees that a day's average temperature is below 65oFahrenheit. Thus, the higher number of HDD the lower the average daily temperature.
