An infeasibility occurs when EMarketOffer cannot find an optimal dispatch solution meeting input supply, reserves and transmission constraints for a given Trading Period. When displaying Forecast results, infeasibilities in the Current Period are displayed in the Messages Panel of the Main Window Control Panel. Even where infeasibilities do occur, EMarketOffer may find a dispatch solution by relaxing constraints, in which case messages in the Messages panel will indicate that while some Constraints have not been fully met.
If no solution can be found that meets the laws of conservation of energy (i.e. there is not enough Generation available), then no Generation or power flow data will be shown.

When analysing the cause of an infeasibility, consult the Circuit Loadings and Equation Constraint Freedoms in the Main Window Information Grids. Loadings over 100% and negative freedoms indicate the related Constraints have not been met.
NOTE: All infeasibility messages for an entire Forecast will appear together in the Messages panel on entering Forecast Summary Mode.
