Where can you find the latest propane prices?

The U.S. Energy Information Administration publishes weekly prices for residential and wholesale propane on its website. It orders the data by data series or area, and the information is downloadable in a spreadsheet format.

The U.S. Energy Information Administration, or EIA, only collects weekly residential and wholesale propane prices during the heating season, which runs from October to March. As of 2015, available historical data reaches as far back as 1990. The EIA revised regional and national price data from 2009 to 2013 due to an update in weighting methodology, and it details the changes in the spreadsheet. Data from the past week is often subject to revision due to late submissions.
