Must Take Zone Link Sale Contract Type
This contract type is a must take for a transmission link energy amount, and works the same as Must Take Zone Link, except that is only tracks sales, i.e., when Zone 1 is exporting, or equivalently, when power is flowing from Zone 1 to Zone 2.
When this contract type is specified, the Energy Max field should be in the form Zone1_Zone2, where Zone1 is the Zone ID for the first zone, etc. The model will then use the energy on that zone-to-zone link for the energy amount of the contract. If there is flow in the positive direction, then this is negative contribution to the energy in the portfolio, like a sale, and the energy will be the amount transferred (multiplied by -1). The sale price will be the market price in Zone 2.
