D.83-10-004

D.83-10-004 authorized SDG&E to construct a single circuit 230 kilovolt (kV) transmission line between its existing Imperial Valley Substation and the La Rosita Substation in Mexico. Five miles of the line are on the United States side of the border and four miles on the Mexico side of the border. Although SDG&E was authorized to construct the transmission line on double circuit tower structures, D.83-10-004 prohibited SDG&E from adding a second circuit to the Imperial Valley-La Rosita transmission line until certain conditions were satisfied.

Finding of Fact 16 and Ordering Paragraph 5 of D.83-10-004 state that SDG&E was not to add a second circuit to the transmission line until a contract (or contracts) for purchase of an additional 220 megawatts (MW) of firm power between the Commission Federal de Electricidad (CFE) and SDG&E and/or Southern California Edison (SCE) was executed and provided to this Commission. SDG&E constructed the Imperial Valley-La Rosita transmission line as authorized and until this application, has not sought to modify this condition.
