Germany data quality #5422

Closed mueslo closed 1 year ago

mueslo commented 1 year ago

Description

German data quality is currently very bad. As far as I can tell, it's because for the past week or so, for example, ENTSO-E has only been reporting a few types of generation units for Germany (Geothermal, Offshore Wind and Lignite).

Electricitymaps is showing some estimate that is extremely wrong and misleading (way too much pumped storage generation, wind often far too low). It is probably better to grey out Germany like other countries for which data is not available until better data is available.

Hi @mueslo thanks for opening this issue!

I don't think we are going to disable the estimations for Germany as there are both internal and external services that rely on that data being available, even if degraded due to the lack of source data from ENTSO-E.

However we are working on improving the estimation models, especially for solar and wind. I'll check with the team on Monday and see what they say about the issue. I'll also reach out to ENTSO-E on Monday and see what they say.

I would also like to note that once the data is available again we will re-fetch it and correct our data.

TransnetBW currently reports N/A for every type of generation they would usually report on. It seems like the other three transmission system operators report correct data (hence lignite, offshore wind and geothermal are unaffected, as these types of generation do not exist in Baden-Württemberg). Maybe electricitymaps could use the available data from other transmission system operators, and only estimate the TransnetBW numbers that are missing. Or maybe if it's impossible to implement quickly, I guess TransnetBW would hopefully fix their Entso-E reporting soon.

Okay so TransnetBW started reporting good numbers again before I could reach out to ENTSO-E so that part should be resolved now at least.

I'll ask someone from the "data" team to re-fetch the missing data which will correct the values for the period TransnetBW was down.
