A) Losses are in megawatts;
B) The distances are exclusive use transmission circuit miles;
C) Subs & Lns are applying dollars in millions using only the substation and transmission line dollars;
D) All Trans includes all the transmission system except generation costs and are in millions.
E) One Mod is an example to add costs to one substation, George, and determine who shares the improvement costs.
