    Dear All,
    In one modeled scenario, fuel switching or fuel blending is applied to the installed power generation unit. Practically, implementing this scenario requires modification of a generating unit and costs are required in this modification.
    Are there any suggestions on how to include adjustment costs for an installed power-generating unit so that the designed scenario can accommodate fuel switching or fuel blending?

    Thank You.

    That's a tricky one. Normally LEAP only applies unit process capital costs when a process is built (i.e. the MW value increases). But in this case, I think this is a situation more like refurbishing a plant - so the capacity does not change.

    One workaround you could try is to have two different named processes in LEAP to represent the "before" and "after" plants. You'll then need to retire MW from the "before" process and add MW to the "after" process . That should cause the capital cost calculations to properly kick in.

    Good luck!

    Charlie

    Thank you for the suggestion.
    I'll try this method in the model.

    I'm also considering this, especially for co-firing CFPP scenarios. I'm thinking of including retrofitting costs in the FO&M costs, in an AnnualizedCost. Does it make sense?

    I'd just say to be careful that one-time costs don't get turned into a recurring annual cost, which would cause an overestimation of the retrofitting costs.
