Located on Rover Avenue between Rachel Street and McFarlane Street North, this building was constructed as part of the Winnipeg Hydro Electric System (later known as City Hydro, now Manitoba Hydro) system that brought electricity into Winnipeg from the Pointe du Bois Generating Station. Tenders were called in December 1909 and the Consulting Board of Engineers selected the J. McDiarmid Company offer over the lowest bid of the Claydon Construction Company.
A spur line to the site was built from the Canadian Pacific Railway main line down Rachel Street. Site excavation was completed and construction of a two-storey brick and stone building, measuring 60 feet by 100 feet, took place during the first half of 1910, then equipment was installed. The finished structure included a full basement. Bricks were provided by the Winnipeg Brick Company.
The building underwent operational testing in early October 1911. Power brought by transmission lines from Pointe du Bois was stepped-down here from 60,000 volts to 12,000 volts before being redirected around the city. Initially, three sub-stations were planned: the downtown Sub-Station No. 1 on King Street, Sub-Station No. 2 on McPhillips Street, and Sub-Station No. 3 on May Street, where the voltage was further reduced for transmission to local service lines. In 1919, Sub-Station No. 5 was built in the southern part of the city.
The original structure has been enlarged several times, starting in 1913-1914 with a $35,000 extension built by the Fort Garry Construction Company. In 1924, the adjacent properties were acquired from the Winnipeg Electric Railway Company. The street address for the facility changed from 30 Rover Avenue to 199 Annabella (formerly Rachel) Street.
A concrete wall was built around the facility following the 1950 flood. A small plaque on the wall indicates the maximum height of floodwater.
