Much of Hydro One’s transmission system was built in the 1950s and is in need of investment. That’s why in mid-June 2019, we will start work to expand the Minden Transformer Station (TS). 

Once complete, this expansion will provide much needed electrical capacity for the Minden and Haliburton areas. The station is located on Haliburton County Rd 21 in Minden Hills. Investments in the system today will help protect the public, ensure reliability and offset far more costly work in the future.

What's included in the expansion?


• Installation of the new T1 transformer in its permanent location on the northwest side of the station.

• Tree removal on Hydro One's property and extension of the station's fence by approximately 0.28 hectare.

• Installation of the new T2 transformer and associated equipment.

• Installation of two (2) new buildings which will house critical electrical communication equipment.

• The removal of the old T2 transformer and associated equipment.


Work will be done primarily with equipment such as bucket trucks, all-terrain vehicles and heavy machinery.
