Also simply known as the “Chapman Street Car Barn” after the street it faced onto and that the cable line ran along before heading up to the Heights.
After the cable line was discontinued in 1904, the power house seems to have passed into the hands of Portland General Electric, which operated it as Power Station “D” for about a year, as mentioned in a July 12, 1905 “Oregon Daily Journal” article. Along with PGE, it was absorbed into the property of the Portland Railway, Light & Power Company in 1906 and was eventually sold off for $15,000 in 1909. A contract was let for its demolition on June 5, 1910.
