Electric Power Annual Report Revision

April 2011 Revision Notice

Revisions in Form EIA-861 data associated with three utilities in Illinois have resulted in changes to Chapter 7 Tables.

Revisions in Form EIA-923 data associated with three power generating plants in Maine, Ohio, and Texas have resulted in changes to tables ES1, 2.1, 2,1A, 2.2, 3.1, 3.2, 3.3, 5.2 and 5.3. In Maine, the consumption of black liquor was revised at a plant. In Ohio, revisions were made to the energy source codes for two boilers at one plant from 'Other' to 'Other Gas.' In Texas, generation attributable to black liquor, wood solids, and natural gas was revised at one plant.
