Flow on Midpoint to Robinson Summit 500 kV Line, metered at Midpoint
2000 MW north to south; 2000 MW south to north (The Phase 1 study report
only documented a maximum flow capability of 1400 MW north to south.
The Phase 2 studies will demonstrate a higher flow by considering other
planned projects (e.g., MSTI or Overland).)

Studies are being performed using a heavy summer base case for north to
south flows and light winter base case for south to north flows. In order to
achieve maximum flows, the north to south studies will include cases
modeling other planned future projects such as the MSTI project or the
Overland DC line.
