Gasoline prices averaged $3.688 a gallon in the Seattle-Tacoma-Bremerton area in April 2013, the U.S. Bureau of Labor Statistics reported today. Regional Commissioner Richard J. Holden noted that area gasoline prices were down 43.9 cents compared to last April when they averaged $4.127 per gallon. Seattle area households paid an average of 9.5 cents per kilowatt hour (kWh) of electricity in April 2013, up from 9.2 cents per kWh in April 2012. The average cost of utility (piped) gas at $1.176 per therm in April was less than the $1.246 per therm spent last year. (Data in this release are not seasonally adjusted; accordingly, over-the-year-analysis is used throughout.)

At $3.688 a gallon, Seattle area consumers paid close to the $3.647 national average in April 2013. A year earlier, consumers in the Seattle area also paid close to the national average for a gallon of gasoline. The local price of a gallon of gasoline has been within 4 percent of the national average in the month of April in each of the past three years. (See chart 1.)

The 9.5 cents per kWh Seattle households paid for electricity in April 2013 was 25.8 percent less than the nationwide average of 12.8 cents per kWh. Last April, electricity costs were 27.6 percent lower in Seattle compared to the nation. In each the past five years, prices paid by Seattle area consumers for electricity were less than the U.S. average by at least 25 percent in the month of April. (See chart 2.)

Prices paid by Seattle area consumers for utility (piped) gas, commonly referred to as natural gas, were $1.176 per therm, or 15.3 percent above the national average in April 2013 ($1.020 per therm). A year earlier, area consumers paid 31 percent more price per therm for natural gas compared to the nation. In the past five years, the per therm cost for natural gas in April in the Seattle area has varied between 12.2 and 31 percent above the U.S. average. (See chart 3.)

Technical Note
Average prices are estimated from Consumer Price Index (CPI) data for selected commodity series to support the research and analytic needs of CPI data users. 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.

The average price per kilowatt-hour represents the total bill divided by the kilowatt-hour usage. The total bill is the sum of all items applicable to all consumers appearing on an electricity bill including, but not limited to, variable rates per kWh, fixed costs, taxes, surcharges, and credits.  This calculation also applies to the average price per therm for utility (piped) gas.
