Description:	Coefficient of number of hours of operation.

Generator Constraints Hours of Operation Coefficient is the coefficient of the number of hours of operation of the facility in the given period in the constraint.

This coefficient can be used to create a constraint that limits the number of hours of operation of a multi-unit facility.

Table 1: Hours of Operating Coefficient Example
Membership	Property	Value
Constraint	Sense	<=
Constraint	RHS
Constraint	RHS Day	17.5
Generator Constraints	Hours of Operation Coefficient	1

For the example in Table 1 the facility is restricted to operating 17.5 hours per day. Note that adding this coefficient causes the mathematical programming problem to include binary decision variables. And also note that the constraint may not be honoured in a linear relaxation (Unit Commitment) when a partial unit is generating in one operating hour.

This constraint also may generate unexpected results in the partial chronology, since integer and temporal constraints are relaxed.
