Ah no I should have made it clearer. I meant this for the LP model actually. While its not uniquely defined and there is a certain irreducible approximation error there...

The value calculation for df_period is correct as per the formula. Initially I had thought the value for 2060 was suspicious as it was lower than the one for 2070...

https://github.com/Wegatriespython/message_ix/blob/price_spike/%23973/message_ix/tests/test_nonuniform_periods.py Got a simple reproduction of the issue going. ### Structure: Single region, single commodity (electricity), single technology (gas power plant) - Growing demand: 100 * (1.05^t_elapsed) GWa for t_elapsed...

Using the CRF formula : for r >0 $$\text{CRF}(r, n) = \frac{r (1+r)^n}{(1+r)^n - 1}$$ r = 5%, n = 30, CRF ~= 0.0654 For Inv cost = 800, annualized...

I'm not sure, so the picture as I see it is at the optimal solution the zero profit condition holds and the model balances all its costs across the horizon(allowing...

As an addendum model_core.gms is very large and strictly speaking its model core ++ at this point. I was wondering if it would make sense to have an issue to...

Hey Fridolin thanks for the feedback, as it stands its not ready for use yet so I have not pointed it to users. One roadblock before implementation is that I...
