Validation Rule:	≥0
Key Property:	No
Description:	Maximum energy

Generator Max Energy (and its period-specific variants Hour, Day, Week, Month and Year) defines an upper bound on the sum of generator Generation across any interval, hour, day, week, month, or year.

A straight-forward approach to modelling an energy-constrained generator (e.g. a hydro generator) is to place periodic limits on the generator's energy as in Table 1.

Table 1: Hydro Generator Example
Property	Value	Units	Timeslice
Units	1	-
Max Capacity	250	MW
Max Energy Month	24	GWh	M01
Max Energy Month	66	GWh	M02
Max Energy Month	68	GWh	M03
Max Energy Month	63	GWh	M04
Max Energy Month	76	GWh	M05
Max Energy Month	36	GWh	M06
Max Energy Month	77	GWh	M07
Max Energy Month	46	GWh	M08
Max Energy Month	22	GWh	M09
Max Energy Month	4	GWh	M10
Max Energy Month	15	GWh	M11
Max Energy Month	8	GWh	M12

Note the use Max Energy Month variant and time slices (patterns) to change the energy limits by each month of the year.Note the unit of Max Energy is gigawatt-hours not megawatt-hours like Generation.

The simulator converts the energy constraints into Constraint objects. By default the constraints are hard i.e. no violation is allowed. If you prefer to allow violations then use the Max Energy Penalty property.
