Standardization full load hours wind and solar (NL) #388

Open Charlottevm opened 2 years ago

Specifically for the RES, agreements have been made regarding the standardization of full load hours for solar and wind (on land). For wind these full load hours have been specified per municipality, for solar panels they are standardized for the NL. These new full load hours deviate from the full load hours we use (both for municipalities & the NL). The full-load hours we use are quite low compared to the full load hours used in the RES.

Do we want to replace the current full load hours in the municipal datasets and/or the NL dataset with these full load hours? (@marliekeverweij @mabijkerk or anyone else)

If so, what would it entail to change the full load hours? Would we have to change our weather curves or could we 'simply' change the number of full load hours per municipality?

I think this is a very relevant discussion which @MartLubben could weigh in on.

I'm not sure what the current 'standard' full load hours are and I would be cautious in updating them, since the 'standard' is updated regularly to match technology developments. This means on the one hand that it would be good for us to update them as well, but on the other hand, because of their relevance for renewable electricity production, they shouldn't change too often.

FYI - for the KEV 2020 we used the following flh:

I propose to not change the full load hours (FLH) by default for datasets.

The full load hours in the ETM are calculated (based on production and capacity). The 'Begrippenkader RES 2.0' describes the FLH of new turbines, not the existing ones, nor the average for an ETM scenario.

An example:

Municipality A has 2 *3 MW turbines with currently 2000 FLH. It builds a 6 MW new turbine with 3000 FLH, the average is 2500 FLH in an ETM scenario.
Municipality B has no turbines and builds a 6 MW turbine with 3000 FLH, the average in an ETM scenario is 3000 FLH
Municipality C has 2 * 3 MW turbines and builds no new turbines, the average. in een ET scenario is 2000.

Concluding, it really depends per situation what the full load hours of wind in an ETM scenario are. The 'Begrippenkader RES 2.0' standardises the FLH for new turbines, but not for an ETM scenario.

The full load hours in the ETM are calculated (based on production and capacity).

This is only the case for wind energy. For solar we use another source, which seems quite old since it is based on a calculation in the source analysis of the eu2012 dataset. This screenshot is from the analysis manager for nl2019:

@mabijkerk Good point!

Begrippenkader RES2.0 defines 900-950 full load hours for solar panels and 350 Wp per panel. I could image that we increase the full load hours and the efficiency slider in the start situation of datasets to match the 'Begrippenkader'. However this should not have priority ( i.m.o.). The diff is quite low and I can imagine it is more complex than simply changing two numbers. I can image it has quite some effect on many scenarios.
