Add curtailment data?

As wind and solar curtailment become more prevalent, tracking and understanding how curtailment fits into the energy transition becomes more and more important.

So, is this something we should track?

I am thinking something like changing production parsers to be able to add curtailment:

    {
      'zoneKey': 'FR',
      'datetime': '2017-01-01T00:00:00Z',
      'production': {
          'biomass': 0.0,
          'coal': 0.0,
          'gas': 0.0,
          'hydro': 0.0,
          'nuclear': null,
          'oil': 0.0,
          'solar': 0.0,
          'wind': 0.0,
          'geothermal': 0.0,
          'unknown': 0.0
      },
      'storage': {
          'hydro': -10.0,
      },
     'curtailment': {
          'wind': 0,
          'solar': -10
     },
      'source': 'mysource.com'
    }

Although there are not many places where curtailment is reported, I noticed that japan has a time series for it (although as far as I can tell it has always been 0). I wonder if Germany or other countries that use curtailment more often report it somewhere?

Thumbs up if you like the idea 😃 Comments/Crits welcome

Thanks for these. This is really cool. Do you know if ENTSOE accounts for curtailment in its numbers already (I assume they account for it, but maybe you know for sure)? Or are we actually missing this data? I’d also like to use the data and make it more visible. I’ll reopen this and see if there is any more garnered interest. I dont have any more ideas off the top of my head other than making it more visible on electricity map and using it to improve our marginal carbon intensity calculations. You?!

@robertahunt and here is one more website for D-1 East German line load: https://www.50hertz.com/de/Transparenz/Kennzahlen/Netzdaten/Netzbelastung/ Watch many lines turn orange/red on windy days 😉. AFAIK large accessible json dataset of the data you see. again no layer of windspeed or irradiation to create more context. by the way: curtailment can go up to a few GW sometimes, which are usually comoensated by fossil sources on the other side of the congested part, so I think there is an impact on CO2 for sure. DM me on slack if you have ideas to use any of these links. ive been thinking about using such data and making something useful from it for the public for quite a while, happy to help ! 😃
