When using commitment optimization, it will force a commitment resource to operate at specific levels determined by the value of the block size.

 

For example, if a resource’s capability is 100 MW and the block size is 25 MW, then the resource can output at one of the following levels:

 

• 25 MW
• 50 MW
• 75 MW
• 100 MW

The unit will operate at the same level, one of the blocks, for every hour.

If the block size is less than or equal to 0, no constraint is applied.

 NOTE: Inputs can be specified for any time period (annual, monthly, weekly, hourly or sub-hourly). For information on how to specify a time series for a variable, see Entering a Time Series.
