Seattle City Light (electrical utility company) is moving ahead with plans for building a new substation in the city, the first one in 30 years. The site used to be a Greyhound bus maintenance facility a long time ago. Early planning is that 115kV or 230kV transmission lines will come into the substation. The three alternatives under consideration are:
– A downtown underground route, primarily along Sixth Avenue
– A route that utilizes the downtown Metro bus tunnel
– An aerial route that crosses I-5 twice and traverses Capitol Hill << this does not sound good!Yes, it’s cheap, but unsightly and not nearly as safe as an underground route.
