The estimated capital costs for all of the projects reflected in Figure PR-6 are shown in Figure PR-7. The figure shows that the combined capital costs for 10-Year Assessment projects that are completed, canceled, replaced, in licensing and under construction account for roughly 86 percent of the estimated total 2001-2008 capital costs, with future projects accounting for the remaining 14 percent of the total. The estimated capital costs depicted in Figure PR-7 are based only on those projects listed in the previous and current Assessment(s) that affect system performance.

The cost estimate for all 2008 10-Year Assessment Update projects to be placed in-service through 2017 is approximately $1.3 billion, which is $100 million less than the 2007 Assessment estimate. Figure PR-8 categorizes the current $1.3 billion 2008 Assessment project dollars by status. Planned projects (including those projects in licensing and under construction) account for 59% of the Assessment dollars, proposed projects account for 13% of the dollars, and provisional projects account for the remaining 28% of the dollars. Other anticipated projects, including substation equipment replacements, pole and conductor replacements, most T-D interconnections, road relocations and generation interconnections not included in the 2008 10-Year Assessment, make up the remaining $1.4 billion of the $2.7 billion in capital expenditures that ATC projects through the year 2017.
