Technology lifetime different depending on the year?

[khainsch]

We found that in the current data model, the technology lifetime differs for different years. In GENeSYS-MOD, lifetime is set once per technology and does not change.
My question would be how other frameworks handle this and what a possible solution would be. Possible points to consider:

• How relevant is lifetime in 2016? Since capacity expansion should not be required in 2016, 2030 becomes the first period where lifetime becomes relevant.
• There is only one Technology which has a lifetime of <20 years (Batteries in 2016). That means, that all other technologies will serve for 2 Periods (2030 and 2050), even batteries since the lifetime in 2030 is 25 years.
• The only difference would be in the potential calculation of salvage values / discounting the value of the technologies.

Would like to hear some opinions, in theory it would be possible to adapt the paramter into GENeSYS-MOD but maybe we find a different solution.

From the discussion 18.02.21, the following was noted:

• urbs, Balmorel can adjust the lifetime of technologies for each year

If you, @khainsch, have big problems implementing an adjustable lifetime per year, we make the decision in the further process to set a constant lifetime for each technology or not

Has this been settled or forgotten?
From my memory I think we handled it by providing capacities for each year - but I am not sure if there is still an issue?

I think from my side this is settled. we have only one parameter for every technology

[sonercandas]

from my side too

From my memory I think we handled it by providing capacities for each year - but I am not sure if there is still an issue?

The issue regarding the capacities was clarified. For 2030 and 2050 initial installed capacities for the energy system have been provided.

However, in terms of lifetime, we should summarise how everyone then implements lifetime per technology.
Options:
A. Only implement 1 lifetime per technology from: 2016 (or) 2030 (or) 2050 (e.g. A 2016)
B. Implement a different lifetime for each year, as given in the input files (results in using 3 different lifetimes per technology)
