Study also includes Dominion estimates for revenue impact that certain environmental projects would have had on residential class in absence of capped base rates during 2002-2007.
Extraordinary expenses result from stricter environmental standards, principally for nitrogen oxide (NOx).
Provisions for such projects were not included in the models cited above, since there is no historical experience with this type and magnitude of expense in Dominion Virginia Power’s rate structure.
