Dear Charlie & everyone,

Trying optimization in Electricity Generation with the base year not set to Zero as in the Optimization Exercise, I noticed that the "Optimized Capacity" neglected the Exogenous Capacity set in the base year. This results to the Optimized Scenario having a higher cost than some scenarios like coal only, NGCC only, oil only and hydro only. This is because all capacities in the year following the base year are new additions which incur capital cost.

Since, all areas would have existing capacities in the base year, I think the optimization should take into account existing capacities.

Did I make a mistake in any setting that made optimization neglect the base year capacities? Hoping for your prompt response.

Thank you.

Edito

Hello Edito,

You've actually touched on an issue in LEAP's optimization routine that we're aware of, and have fixed for the next version of LEAP (we expect to be able to release this shortly).

Currently, optimized transformation modules treat Exogenous Capacity, specified in Current Accounts, as having been built in the first scenario year. This means that the cost of that capacity is included in LEAP's social costs, whereas it would not have been included in non-optimized scenarios.

Your question is actually quite similar to another question that I recently answered - I'll provide the link to that, for context.

Apologies that we continue to work out some issues with optimization, but we certainly recommend that you stay tuned for the next software update!

Take care,

Taylor

Hi Taylor,

I used LEAP 2012.0.0.54 and it has resolved the problem I raised above. Optimization now uses the base year exogenous capacity values.

Thank you very much.
