more precise representation of grouping years #29

Closed JulianGeis closed 5 months ago

JulianGeis commented 7 months ago

Finer and earlier categorisation into grouping years to better represent the existing capacities.

Why? With add_brownfield, it is not the DateIn that is used to decide what is removed due to the lifetime, but the grouping_year. However, the first year of the grouping_years so far was 1980, which is why everything that was built before then is set to 1980. This means that nuclear power plants such as in Belgium, which were built in 1975 and have a DateOut of 2025, have a build_year of 1980 and a lifetime of 51 years (DateIn - DateOut + 1). In other words, they will not be taken out until 1980+51=2031.

I would like to fix this in pypsa-eur and keep the 5 year delay. But we should nevertheless add the grouping years 1960 - 1975!
