The UDC constraints in this file use TotalCapacityAnnual directly while the other versions compute capacity as a sum over NewCapacity and ResidualCapacity. Ensure this difference is intentional and that the constraint formulations remain consistent with the model requirements.

The usage of the TotalCapacityAnnual in the osemosys.txt is fine. In the other code versions this variable just can't be used since it is commented out.
So this shouldn't prevent closing the PR.

Do you agree that the use of TotalCapacityAnnual in the osemosys.txt is fine @abhishek0208 ?

sum{t in TECHNOLOGY}UDCMultiplierNewCapacity[r,t,u,y]*NewCapacity[r,t,y] +
sum{t in TECHNOLOGY}UDCMultiplierActivity[r,t,u,y]*TotalTechnologyAnnualActivity[r,t,y] <= UDCConstant[r,u,y];
