Average Energy Prices in the Philadelphia Area – March 2012

Consumers in the Philadelphia area paid more for electricity (27.6 percent) and utility (piped) gas (22.5 percent) than the U.S. city average in March 2012, as measured by the Consumer Price Index (CPI), the U.S. Bureau of Labor Statistics reported today. Sheila Watkins, the Bureau’s regional commissioner, noted that gasoline prices for the Philadelphia area remained close to those nationwide as both local and national gasoline prices increased over the year. (See table A. All data in this release are not seasonally adjusted; accordingly, over-the-year analysis is used throughout.)

Technical Note

Average prices for electricity, utility (piped) gas, and gasoline are published monthly for the U.S. city average, the 4 regions, the 3 population size classes, 10 region/size-class cross-classifications, and the 14 largest local index areas. For electricity, average prices per kilowatt-hour (kWh) and per 500 kWh are published. For utility (piped) gas, average prices per therm, per 40 therms, and per 100 therms are published. For gasoline, the average price per gallon is published. Average prices for commonly available grades of gasoline are published as well as the average price across all grades.

Price quotes for 40 therms and 100 therms of utility (piped) gas and for 500 kWh of electricity are collected in sample outlets for use in the average price programs only. Since they are for specified consumption amounts, they are not used in the CPI. All other price quotes used for average price estimation are regular CPI data.

With the exception of the 40 therms, 100 therms, and 500 kWh price quotes, all eligible prices are converted to a price per normalized quantity. These prices are then used to estimate a price for a defined fixed quantity.
