$23 B transmission line upgrade

The Midcontinent Independent System Operator says at least $23 billion is needed to update its transmission lines. “Because of the impact of increasing load growth and the changing resource mix, the current potential Tranche 2 portfolio features 765 kV lines which enable long-term value based on distance, cost and land use. They also reduce right-of-way permitting needs required in regulatory approval processes and help address environmental concerns.”
