Construction Year

See also: 

Used only when conducting transmission modeling as part of full energy system optimization. Transmission modeling is enabled by editing the Transmission Networks setting in the Settings: Optimization screen.

This variable is specified for each Transmission line ().  Use it to exogenously specify the construction year of each line. Set it to zero to  have the construction year determined endogenously by LEAP's optimization calculations (i.e., for candidate lines).

As with other variables used in optimization modeling, this variable is only available for optimized scenarios.  It is not visible in Current Accounts.
