The Municipal Electric Light Plant was located in 11th Street and had a spur from the D&RGW to deliver coal as there were coal bins adjacent to the structure - from what I have read by 1911 it was no longer being used used for power generation. The building later became a maintenance building for San Juan County and was demolished in 1946 as part of road works on 11th Street.
The Animas Light & Power Company building, pictured in the Google view was/is located next to the SN trackage between Silverton and Waldheim, in the current industrial area and commenced operating in November 1906.
