Completed major projects

We develop materials to inform Manitobans about the process behind building and expanding our system and infrastructure. To receive federal and/or provincial approval for projects, detailed filings are submitted, which include environmental impact statements, community engagement materials, construction schedules, environmental protection and management plans.

Bipole III Transmission Project

Bipole III is a high voltage direct current transmission line that delivers renewable energy to southern Manitoba, helping to reduce reliance on fossil fuels. Completed in July 2018, Bipole III strengthens the reliability and security of Manitoba’s electricity supply.

Bipole III starts at the Keewatinohk converter station near Gillam in northern Manitoba. It travels 1,388 km south to end at the Riel converter station in the RM of Springfield.

Regulatory approval & filings

Development of Bipole III required a Class 3 license under The Environment Act (Manitoba).

Manitoba Environment and Climate Change granted Environment Act Licence No. 3055 (gov.mb.ca) to Manitoba Hydro on August 14, 2013 for the construction, operation, and maintenance of the Bipole III Transmission Project. Read the Clean Environment Commission (CEC) report.

The project’s environmental assessment included an engagement process and identification of potential impacts and mitigation measures. It is documented in the Environmental Impact Statement (EIS).

Route adjustment fillings

Route adjustment fillings

On January 28, 2013, we submitted a supplemental assessment report on 3 route adjustments to Manitoba Environment and Climate Change. The report outlined the environmental assessment undertaken at the request of Manitoba Environment and Climate Change for the 3 route adjustments and was the focus of review at the Clean Environment Commission Public Hearings that were held in early March 2013.

On February 19, 2013, we filed the following supplemental material with Manitoba Environment and Climate Change:

Environmental protection

The Environmental Protection Program (EPP) for the Bipole III Project prescribed mitigation and protection measures to avoid and reduce potential environmental and social effects.

As part of the regulatory review, a table (PDF, 862 KB) was submitted to the Clean Environment Commission and to Manitoba Environment and Climate Change outlining all the mitigation measures that were indicated in the Environmental Impact Statement for the Project.

Keeyask Generating Station Project

Keeyask is a 695 megawatt (MW) hydroelectric generating station on the lower Nelson River. It is located 725 kilometres northeast of Winnipeg and 30 kilometres west of Gillam, in the Split Lake Resource Management Area.

The station was developed by the Keeyask Hydropower Limited Partnership (KHLP), jointly owned by Manitoba Hydro and four Manitoba First Nations: Tataskweyak Cree Nation, War Lake First Nation, York Factory First Nation, and Fox Lake Cree Nation. Manitoba Hydro operates the station on behalf of the KHLP, and Keeyask has been fully online since March 2022.

For more information on the Keeyask project, visit the Keeyask Hydropower Limited Partnership website.

Keeyask Transmission Project

This Project consists of transmission lines, station development and station upgrades to support the operation of the Keeyask Generating Station.

Manitoba–Minnesota Transmission Project

The Manitoba–Minnesota Transmission Project (MMTP) is a 500-kV transmission line that exports reliable and renewable energy to Minnesota Power’s Great Northern Transmission Line. Learn more about our export revenues.

The transmission line runs from the Winnipeg area to the U.S. border in southeastern Manitoba. Upgrades were also made to our Dorsey, Riel, and Glenboro converter stations.

Completed on schedule and under budget in June 2020, the MMTP strengthened the reliability of Manitoba’s electricity supply and increased access to American markets. The budget as of March 2020 was estimated at $490 million.

Environmental protection and management plans

These plans were used as guides for contractors and field personnel during the construction and/or operation of the MMTP. They helped us meet environmental legislation requirements and protect the environment.

Contractor plans:

On May 28, 2021, the Canada Energy Regulator sent letters indicating that the Commission has approved Manitoba Hydro’s Crown land offset measures plan and wetlands offset measures plan and no net loss of wetlands plan.

The Wetland Project Agreement was signed by the Province of Manitoba, Manitoba Habitat Heritage Corporation, and Manitoba Hydro on April 20, 2022.

Environmental Impact Statement

An environmental impact statement (EIS) summary document (PDF, 1.5 MB) was developed for the MMTP and outlined the concerns heard throughout the environmental assessment process and how these concerns were addressed.

The EIS was submitted to Manitoba Environment and Climate Change for review in September 2015.

Wuskwatim Generating Station Project

Wuskwatim is a 200-MW run-of-river hydroelectric generating station on the Burntwood River at Taskinigup Falls. It is located in the Nelson House Resource Management Area about 45 kilometres southwest of Thompson and 35 kilometres southeast of Nelson House.

In 2006, the Wuskwatim Project Development Agreement (PDA) that governs all aspects of the Project, was signed by Nisichawayasihk Cree Nation (NCN) Chief and Council and Manitoba Hydro. The station is owned by the Wuskwatim Power Limited Partnership (WPLP), a legal entity involving Nisichawayasihk Cree Nation (NCN) and Manitoba Hydro. Manitoba Hydro provides management and operational services to the WPLP in accordance to the PDA.
