Ok, you are using an older version of ANSWER-TIMES. You should consider upgrading to the latest version.
I wonder why you now have two inflow commodities HYDS-1 and HYDS-2, and how they are linked to the processes? From my earlier post you can see that I suggested a seasonal storage that would be charged and discharged by a single seasonal inflow commodity, INFLOW.
Anyway, it appears that your current main problem is not related to storage at all. The results you provided show clearly that the power plant process E001 (which I assume to be now a normal process, according to your description?) does not have any transformation: It produces electricity but does not consume anything. But it is impossible to conclude from the results why you don't have any transformation equation for it.
Some questions that might help resolving this problem:
- Did you define the process transformation for the process E001, and if you did, how? For example, did you define a process efficiency for it, and if so, how?
- What is the primary group of the process E001? (It apparently should be ELC).
- What are the input(s) to the process E001? Only HYDS-2? Or both HYDS-1 and HYDS-2?
- What are the types and timeslice levels of the commodities HYDS-1 and HYDS-2?
