Capacity Price Table
This table stores annual capacity prices in $/MW-week by area (note this is regardless of any Unit Conversion, i.e., it is always written in USD). The table is typically the result of a Long-Term study with Use Reserve Margin Capacity Targets checked (Simulation Options > Long Term). It moves the results from the Time Series Annual Table and the Resource Modifier Table (RMT) into one easy-to-decipher location.
NOTE: When opened, this table shows a filtered view based on the areas, zones, or pools running in the study system. The User Default Quick View overrides Automatic Filters, or you can turn them off using the Project Options in the Options window.
The table is named by adding “Capacity_Price_” as a prefix to the RMT name. This indicates to the user that this set of capacity prices was calculated from the same long-term study run that generated the RMT of the same name.
NOTE: Both the Capacity Price and RMTs are written back to the input database for use in subsequent runs, with one exception. They cannot be included “in study” for subsequent long-term runs unless the Use Capacity Price Table as Input is checked. In regular (non-long-term runs, including a Capacity Price table “in study” will not affect the dispatch or calculation of energy prices but will be used to calculate a capacity revenue stream for each resource that resides in an area with non-zero capacity prices. As such, Energy Revenue, Capacity Revenue, and Revenue (sum of energy revenue, capacity revenue, spin reserve revenue, and non-spin reserve revenue) are reported separately. See Resource Output for more information.
You can modify the values in the Capacity Price table and save them in Change Sets like any other input table. However, only annual differentiation is allowed. If the area capacity prices are modified, there is intra-zone differentiation. Aurora will then calculate a capacity-MW-weighted average for the zone. Zone capacity credit is reported in nominal $/MW-week. See Zone Output for more information.
See Long-Term Optimization Logic for more information on long-term studies.
