With the release of data for January 2004, the Producer Price Index (PPI) introduced data for two new industries within the Electric Power Generation, Transmission, and Distribution sector. These indexes, published according to NAICS industry definitions, appear in table 5 of the monthly PPI Detailed Report and are available online through the BLS website.
The industry index for Electric Power Generation, NAICS 221110, measures price changes for the initial commercial transaction received by power generating establishments. This industry comprises facilities that convert other forms of energy, such as water power, fossil fuels, nuclear power, and solar power, into electric energy for sale to electric power transmission and distribution systems. Within this industry, the PPI divided output into two subcategories: electric power generation by utilities and electric power generation by non-utilities.
The index for Electric Bulk Power Transmission and Control, NAICS 221121, measures changes in fees and charges associated with the transmission and control of electric power. Establishments in this industry operate electric power transmission systems and/or control the transmission of electricity from the generating source to distribution centers or electric utilities.
Data for the new indexes compliment already published PPIs within NAICS 221122, Electric Power Distribution. The indexes for residential, commercial, and industrial power distribution have historical data back to December 1990.
