I try to calculate the electricity generation in a ship. But i think scenario year value is incorrect in this analysis. i use the exercise 1,2,3 and 4 for this calculation. How can i solve this problem?

for example; in reference year electricity generation value is nearly 0,01 million gigajoules but in first scenario year that value reach 81 million gigajoules.

I went through your model. The sudden jump in the generation value is due to the fact that the demand and generation does not match.

According to your model, requirements in 2017 is 78.506 and in 2018 it is 88.308 million GJ, while in production/output side, it's 0.027 in 2017 and reaches 88.308 in 2018.

to meet the shortfall in 2017, the model takes it as an import ( according to setting in your model) and after that year, the new batteries come in thus meeting the demand.
