Rocky Mountain Power’s Wyoming expansion approved

They will be connected via a 225-kilometre, 500kV transmission line between Aeolus and Bridger in Wyoming, also due to be completed in 2020.
Elsewhere, Rocky Mountain Power will repower 900MW of its existing wind fleet in the Wyoming and Washington.
New, longer blades and technology upgrades will boost output of these projects by more than 25% and extend the life of the turbines, the utility stated.
The majority of the repowering projects are expected to be completed in 2019, with the remainder following in 2020.

Pacificorp estimates the total investment for the Energy Vision 2020 projects will be just over $3 billion — a reduction from the initial $3.5 billion cost estimate when the projects were first announced in April 2017.
The utility added this was due to changes in the scope of the projects — the proposed 161MW Uinta and 110MW McFadden Ridge wind farms in Wyoming were dropped in order to lower costs, according to the case document before the Idaho Public Utilities Commission.
