Project Background

For the past few years, we have been working with Manitoba Hydro and their Bipole III project which involves two stations, one in Keewatinohk Converter Station in Northern Manitoba and the other at the Riel Station in East of Winnipeg. Both stations are mirrors of each other. The Keewatinohk Converter Station’s purpose is to take the power that is generated at the various dams built up North and convert it to DC (Direct Current) power so it could be moved more efficiently along the many kilometers of hydro line it runs through. As Direct Current, the electricity can move along the power lines without losing as much of its strength as if it is moved as AC power (Alternating Current)


But the power needed by our homes require AC power, so they built a replica station near Winnipeg where they revert the power back to its original AC form, to send it out in a more usable form. The power being generated by these massive stations is well protected in Barkman trenches underground. To build this type of station requires many kilometers of trench to be made which Barkman was committed to giving time and resources for. Both stations are identical in design but function as opposites in their power conversion
