The Grid is the physical design of the lines and nodes
The grid is modelled as a single line between nodes, therefore if the physical grid has more than one line, this needs to be reflected in the values associated with the line. The physical aspects of the line, Resistance and Reactance are modelled to determine losses. Lines limits can be applied using 'Enforce' so constraints can be modelled.

- Name and Description fields used to identify and describe the Grid Resource
- Base Voltage, Determines the variable losses that occur on a line through the formula: Loss = RZ2 / Base Voltage, where R is the per unit resistance of a line and Z the power flowing through the line in MW.
- Comments
- Nodes need to be present before a line can be entered
- Individual line limits can be modified for defined periods using the schedule
- Individual lines can be entirely 'outaged' through the schedule
- Data can be copied directly from excel cells into cells in EMarket
