Bipole III Transmission Reliability Project
Bipole III is a high voltage direct current transmission project under construction in Manitoba that will deliver renewable energy to southern Manitoba and the United States, helping to reduce reliance on fossil fuels. Once completed in 2018, Bipole III will strengthen reliability and security of Manitoba's electricity supply by reducing dependency on existing high voltage direct current transmission lines and the Dorsey Converter Station. We currently rely on these facilities to deliver over 70 per cent of the electricity produced in the province.
Bipole III is a renewable energy project and 1 of the 20 largest projects under construction in North America.
Help us build a reliable energy future.
The project will strengthen the reliability and security of Manitoba's electricity supply by reducing dependency on existing high voltage direct current transmission lines and the Dorsey Converter Station in southern Manitoba.
Total electricity that can be delivered using Manitoba Hydro's transmission system.
The amount of electricity our customers use during the coldest days of the year.
A failure of the Bipole I + II transmission system could mean we cannot carry enough electricity to meet our customers demand – resulting in blackouts.
When Bipole III is completed it will significantly increase Manitoba Hydro's transmission capacity. That means there is no shortfall in our ability to meet customers electricity demands should Bipole I + II fail.
The project will also provide additional capacity to deliver renewable energy from the Keeyask Generating Station currently under construction to meet Manitoba's growing demand for electricity and fuel our province's prosperity.
Bipole III adds 2,000 megawatts to Manitoba Hydro's high voltage direct transmission capacity increasing our ability to deliver renewable electricity from hydro generating stations in northern Manitoba.
The value of reliability
Watch our video to learn more about transmission connections and the value they provide our customers by enhancing reliability.
Construction across all parts of the project will continue over the winter months. Construction environmental protection plans approved by Manitoba Conservation and Water Stewardship.
To maintain safe public access, travellers to the construction areas are asked to contact us ahead of time to arrange for appropriate escorts though the security gates and past hazardous work zones.

First tower raised on Bipole III
The first steel tower of the Bipole III Transmission Reliability Project was raised on March 11 north-east of Thompson.
A good winter for Riel construction
This video update describes this winter's progress constructing the Riel Converter Station, located just east of Winnipeg.
