Bipole III is a new high voltage direct current (HVDC) transmission project required to improve overall system reliability and dependability. Projected in-service date for this project is anticipated for 2017.
Manitoba Conservation and Water Stewardship has approved the Construction Environmental Protection Plan for the Riel Converter Station Facilities, Infrastructure and Ground Electrode in accordance with Clause 4 of the Environment Act Licence. View the Construction Environmental Protection Plan.
Manitoba Conservation and Water Stewardship granted Environment Act Licence No. 3055 to Manitoba Hydro on August 14, 2013 for the construction, operation, and maintenance of the Bipole III Transmission Project.
We received approval for Licence Clause #8 of the Environment Act Licence, which concerned routing in southern Manitoba where the transmission line was not located on the half mile alignment. The report and outcomes can be found at Manitoba Conservation and Water Stewardships Public Registry.
Due to the heavy reliance on one transmission corridor and a single converter station in the south (Dorsey), the system is vulnerable to extensive power outages from severe weather (major ice storm, extreme wind event, tornado), fires, or other events.
Studies have concluded that a new transmission line and associated facilities would improve system reliability and reduce dependency on Dorsey Station and the existing HVDC Interlake corridor. The Bipole III Transmission Reliability Project would also establish a second converter station in southern Manitoba, to provide another major point of power injection into the transmission and distribution system.
