When modelling fuel costs in Times, I understand, one could use IRE_PRICE to input the cost of importing the fuel. In a case like this one, all processes that consume NG pay the same price for it .
If different processes pay different prices, for example, in the case of natural gas for OCGT and CCGT, is it correct to use FLO_COST instead of IRE_PRICE?
In both cases, if I want to know, for example, the short run marginal cost of producing electricity for a specific process using a natural gas combined cycle, I need to add VAR_ACT.M from the electricity process and VAR_FLO-IN.M, is this correct?.
Thanks
