Movement on Great Northern line
Minnesota Power files Certificate of Need application for 500kV link
Allete division Minnesota Power has filed a Certificate of Need application for the 500kV Great Northern Transmission Line with the Minnesota Public Utilities Commission.
The 240-mile scheme will link to a Manitoba Hydro transmission line at the Canada-US border and carry renewable power from the Canadian province of Manitoba to a Minnesota Power electric substation on Minnesota's Iron Range.
It is needed to support delivery of hydro energy from two new projects in northern Manitoba that will be capable of producing more than 2GW.
The Great Northern Transmission Line is expected to facilitate the delivery of at least 750MW into the US and from June 2020 Minnesota Power will use it to deliver 250MW from Manitoba Hydro through a power purchase agreement approved in early 2012.
Construction is expected to begin in June 2016 subject to securing permits. Minnesota Power will own 51% of the line while a subsidiary of Manitoba Hydro will own the remainder.
The company estimates that construction in the US, including substation work, will cost between $400m and $600m depending on the final route.
