As was the case in the substation build-ing itself, the bus structures and other ap-paratus in the yard have been laid outfor very convenient extension. The prob-lem of forecasting future development orgrowth is a difficult one, and it has in-variably proven the case that the most op-timistic provisions for the future haveproven inadequate in a very few Costa Substation has been so de-signed that it can readily accommodate anydemands which the future may require ofit, and while at present the station issmall in point of installed electrical capacitywhen compared w
