Scarcity Pricing Function Column (Optional)
Column Type = Text
The optional Scarcity Pricing Function column provides the option for resources to get paid a scarcity premium based on the zonal reserve margin (in percentage terms) in each year, similar to the application for Capacity_Revenue payments. The column should be populated with a reference to a vector in the Time Series Weekly table that defines a piecewise linear function where the domain is the annual peak reserve margin (from 1 to 168) and the output of the function is the real currency/kW-yr scarcity revenue value to be used.
For each year, Aurora will calculate the reserve margin and then attribute Scarcity_Revenue to each generator based on the function and their contribution to the reserve margin. The scarcity revenue will be attributed hourly, but each hourly value will be constant over the whole year so that it sums to the correct amount. This revenue will be calculated in both long-term capacity expansion studies and standard pricing studies and will be part of the resource Value that is used to calculate the capacity prices at the end of the long-term run, in such a way that the capacity prices will take into account the revenue already earned from the scarcity pricing.
NOTE: Inputs are specified as a weekly vector via a reference to an ID in the Time Series Weekly table (or nested in a Time Series Annual reference). See Entering a Time Series for more information.
