General comments:

-   A question arose in regards to a fourth scenario using a diversified
    portfolio approach.

-   Ron Schelberg has agreed to provide data on system through Idaho.

-   Colstrip has the ATR device, equivalent to a 500 kV line.

-   We will need to monitor all lines for results (need flow-duration
    curves.)

-   Mike Kreipe has new 500 kV AC & DC data - newly configured to share.

-   Assume 1500 MW rating for all 500 kV lines.
