Overview of the sheet
The Load Dispatch sheet is entirely used for automatic calculations and no data should be entered here. The sheet works as follows:
On a year by year basis, data from the “Units” sheet is copied into the “LoadDisp” sheet and dispatched on a merit-order variable cost basis. The copying and calculating of each year are completed automatically by the model.
The EFFECT Model does this by first focusing on the following “must-run” low-carbon sources from which all available electrical energy that they generate will be used;
- Wind;
- Biomass;
- Solar; and
- Nuclear.
Then the position of Hydro in the load demand curve is located to give a weighted average load factor for Hydro of 50 percent.
The remaining thermal units are then dispatched on a merit-order variable cost basis between the “always-run” and the start of hydro.
All Hydro is then dispatched and the remaining thermal is finally dispatched above hydro to complete the load demand supply.
This load dispatch order—which does not take into account possible synergies between wind and solar, and other temporal and location-based effects-- may give slightly different results than those generated by WASP and other system planning optimization packages that You may use. These differences may vary towards higher or lower GHG emissions depending on the structure and composition of Your country’s power supply sector. Where such differences are quantified, these may be included exogenously in the scenario-based analysis that you will perform using the EFFECT tool.
