The Dow Jones U.S. Daily Electricity Price Indexes are volume weighted averages of wholesale electricity transactions. Calculations for these indexes average power transactions from specific geographic areas. Each index provides a clear spot market indication for OTC trading in that region.
Daily electricity price indexes include:
Dow Jones Palo Verde Electricity Price Indexes Dow Jones PJM Western Hub Electricity Price Indexes Dow Jones Four Corners Electricity Price Indexes Dow Jones Mead/Marketplace Electricity Price Indexes Dow Jones Mid-Columbia Electricity Price Indexes Dow Jones Cinergy Electricity Price Indexes Dow Jones California Oregon Border Electricity Price Indexes Participants provide Dow Jones Indexes with price and volume information, which, in turn, is used to calculate the indexes. Participants are asked to provide Dow Jones with data by 10 a.m. prevailing time on the day after the transacted power moves. Although some Dow Jones U.S. Electricity Indexes are calculated for 365 days a year, publication occurs once a day on business days. If a holiday falls during the week, data is transmitted to Dow Jones on the first business day following a break.
A confidential disclosure agreement with an audit provision is typically entered into by both the participants and Dow Jones Indexes before the data is used. This procedure gives Dow Jones Indexes the ability to insist on a third party audit of the data to ensure that it is sound. Data submissions are used only to calculate the indexes and are not shared with other data providers or index users. This agreement also safeguards the privacy of the information submitted to Dow Jones Indexes and encourages index participants to submit accurate data.
