Key Property:No
Description:Price for violating non-anticipativity constraints in scenario-wise decomposition mode

Generator Build Non-anticipativity applies when the Stochastic Method is set to "scenario-wise decomposition". It is used to identify the first stage build decisions for LT Plan. The property can take any value, but there are two special cases to consider:

First Stage (value = -1)
There is no recourse on the build decisions for this generator. LT Plan enforces the non-anticipativity constraints (that the build decisions for the generator must be identical across all stochastic samples). The value of -1 in fact means a penalty of infinity on the non-anticipativity constraints.
Second-stage or Recourse (value = 0)
There is full recourse on the build decisions. The non-anticipativity constraints are relaxed and the stochastic optimization is free to optimize the build decisions in each stochastic sample separately.

Any positive value then acts as a penalty on anticipating the values of the uncertain inputs. It is a useful feature that the non-anticipativity can be relaxed over time as in the following example:

Property Value Unit Date From Memo
Build Non-anticipativity -1 $/MW
This value acts like infinity, so no recourse is available
Build Non-anticipativity 1000 $/MW 1/01/2015
Build Non-anticipativity 100 $/MW 1/01/2020
Build Non-anticipativity 0 $/MW 1/01/2025 Full recourse is now available on these decisions
