December 18, 2015

    Sales, revenues, and average price to ultimate customers were revised slightly for September 2014 due to a revision in the allocation method for monthly sales and revenues for annual respondents. This resulted in a revision in the percentage change in year-over-year residential sales, between September 2014 and September 2015 (listed in the Key Indicators), to 0.8 percent from its original estimate of 0.9 percent. The sales and revenue revision also induced very minor changes in the state maps in the End Use section.

September 3, 2014

    Revenues for Retail Sales in the state of Illinois were overstated by 41% in June, resulting in a commensurate overstated average price of 41%. This error created an overstatement of the national price of about 1.3% in June. This correction will change the data in Tables ES1A and ES1B as well as Tables 5.2, 5.3, 5.5A, 5.5 B, 5.6A, and 5.6 B. The correction of the overstated revenue can be seen in the residential, commercial, and industrial sectors.

    Nuclear net generation for May 2014 was revised upward from 62,116 gigawatthours (GWh) to 62,947 GWh. This revision altered the year over year (YOY) change in nuclear net generation from -1.2 percent to +0.2 percent. May 2014 coal net generation, meanwhile, was revised downward from 119,486 GWh to 119,483 GWh. On net, these revisions increased total net generation for May 2014 from 322,903 GWh to 323,731 GWh and changed the YOY increase in total net generation from 0.3 percent to 0.6 percent. These changes are also reflected in the Resource Use section of the EMU.
