Assumption that the max hourly interchange value reached between Jan 2019 - Dec 2023 is representative for available transmission capacity between BA's. Distance for planned capacity is converted from miles into km. — This corresponds to the Pacificorp East to Intermountain Power Agency (Utah substation, operated by LDWP) Section of the TransWest Express transmission project.
