Demand projections and fixed initial years

[Pernille.S]

We are currently solving the ETSAP-TIAM model for various demand projections and fixed model results up to 2020.

In this context we observe some strange behavior of the energy service demand in 2030. I assume this is because the end-use demand for 2030 is based on the driver and elasticity of 2020 for the given scenario, and not the driver and elasticity of the fixed model run (gdx-file of the reference run). Is this observation correct? If yes, is it possible to further develop VEDA such that the demand projections are based on the fixed assumptions for 2020?

All help is highly appreciated!

It would be helpful to know what kind of strange behavior of the energy service demand in 2030 we are talking about here. Anyway, if you specify the demand projections by using COM_PROJ, you will override the projections derived from the drivers and their elasticities, and so the demand for 2030 will be directly based on the COM_PROJ you specify for 2030. But perhaps you mean that you use various driver projections? And what about price elasticities, are they in play as well?
