I would like to ask about adding more than 1 specific power plant in Endogenous Capacity tab. I have a scenario that adding three coal sub bituminous power plant in the future, with specific site and different capacity. I specify what plant to build, but i let LEAP determine when it build. How to do it exactly ? Although, i have read about adding two different specific plant with this structure

If( Greaterthan(Year, X), AdditionSizeFirstPeriod, AdditionSizeSecondPeriod)

I still confused about the syntax. Could anyone explain more ? What year X is stand for especially because we cant predict added year of previous capacity ?

Thanks in advance !

The syntax If(year > Y, X, Z), when entered into the Endogenous Capacity variable, means that if LEAP needs to add this capacity in a given year, it will add the amount that is returned by this expression. You may subsitute values for Y, X (the addition size to add, when necessary, before year Y), and Z (the addition size to add, when necessary, after year Y) as you like.

Hope this helps,

However, what underlies generator selection in capacity addition ? Is it based on cost or depend on addition order ?

Thanks in advance

When using the Endogenous Capacity variable to add new capacity, the addition order and addition size of generator is up to you to decide. LEAP simply loops through this list, adding generators in order and in the size specified until the planning reserve margin is satisfied. If it reaches the bottom of the list, it begins again at the top.
