Power sale arrangements
Basin Electric Power Cooperative
On March 1, 2019, we signed a 5-year agreement with Basin Electric Power Cooperative for the sale of up to 80 MW of capacity each year starting in June 2023.
Dairyland Power Cooperative
On December 31, 2020, we signed a 50 MW seasonal diversity exchange agreement with Dairyland Power Cooperative for a five-year term starting June 1, 2022.
Great River Energy
On October 24, 2013, we signed a 200 MW seasonal diversity exchange with Great River Energy of Minnesota that runs until 2030.
Seasonal diversity exchanges allow utilities whose peak loads occur in different seasons of the year to share surplus generating capacity during off peak seasons. This saves both utilities from building generating facilities that are only required at peak times, saving money for their customers.
The Great River Energy diversity exchange means we will provide 200 MW of renewable hydroelectric power to Great River Energy in the summer to meet their annual peak energy needs, while Great River Energy will provide Manitoba Hydro with 200 MW of capacity during the winter when heating demands in Manitoba are the greatest.
Minnesota Municipal Power Agency
On June 1, 2018, we entered into an agreement with Minnesota Municipal Power Agency for the sale of up to 105 MW of annual capacity starting June 1, 2020.
On May 25, 2011, we announced an agreement with Minnesota Power for the sale of 250 MW of renewable hydroelectric power each year over a 15-year period, beginning in 2020.
The sale also required the construction of a new international transmission line, the Manitoba–Minnesota Transmission Project in Canada and the Great Northern Transmission Line in Minnesota. The transmission line went into service June 1, 2020.
Northern States Power
On May 27, 2010, we signed 3 agreements with Northern States Power (part of Xcel Energy) to supply up to 850 MW of renewable hydroelectric power from Manitoba each year until 2025. The 3 agreements consist of a 350 MW seasonal diversity exchange, a capacity sale for 375 MW in the summer and 325 MW in the winter, and an annual capacity sale for 125 MW.
In 2020, we signed an agreement with SaskPower to provide up to 215 MW of renewable hydroelectric power to Saskatchewan each year, beginning in 2022 and continuing for up to 30 years. The new sale will bring long-term benefits to electricity customers in both provinces. This is the largest of 3 recent major power deals between the 2 provinces. By 2022, Manitoba Hydro will be supplying up to 315 MW of renewable hydroelectric power to Saskatchewan each year.
On January 29, 2016, we signed a 20-year agreement to sell 100 MW of renewable hydroelectric power to SaskPower each year, starting in 2020. This sale required the construction of a new 230-kV transmission line from Birtle Station, south of the community of Birtle, to the Manitoba–Saskatchewan border. The Birtle Transmission Project was completed on March 29, 2021.
Wisconsin Public Service
In 2011, we announced an agreement with Wisconsin Public Service for the sale of 100 MW of renewable hydroelectric power each year over the period from 2021–2027.
