Converter stations

A significant amount of Manitoba's electricity is produced by the 5 hydroelectric generating stations on the Nelson River, in the northern part of the province. The electricity generated must travel exceptionally long distances to southern Manitoba, where most of the electricity is used.

It is more efficient and economical to transmit electricity as high voltage direct current (HVDC). Our 3 converter stations convert alternating current (AC) to direct current (DC) for transmission from northern Manitoba to southern Manitoba, and then convert DC back to AC for transmission to customers.

The stations also have large transformers which either step up or step down the voltage.
