Did Germany just surpass 100% renewable power?

Just a week after approaching 90 percent renewable power or more, Germany may have reached 100% yesterday. But the data estimates are still moving.

JOURNALISTS: please check the bullet points below before reporting.

Just a week after reporting a peak of more than 90 percent renewable power, Agora now shows for the first time that green electricity may have briefly touched and slightly surpassed 100% yesterday. However, live stats are just guesstimates, and Agora's now shows slightly less than 90% (some 56 GW of 64.4 GW) on May 8. Here is the new chart for yesterday.

 - 
Agora Energiewende

Expect that chart to change over the next few days. If the past is any indication, the percentage will be revised downwards. And even then, Agora simply may be off. We won't know for certain until next year.

If you would like to write about this, remember the following:

  • No, Germany did not just get 100% of its energy from renewables. It briefly got around 100% of its electricity from renewables. Power makes up some 20% of energy consumption in Germany. The Germans have some 15% green energy overall.
  • Wind and solar cannot produce negative wholesale prices. Wind farms and solar arrays will never pay you to take electricity off their hands; they will simply curtail.
  • Negative prices come from baseload power plants. They are the ones that would rather pay you to consume tha ramp down below their must-run level. So you have got to get rid of baseload if you want solar and wind.
  • No, seriously, you have got to get rid of baseload.
  • Nuclear is the most inflexible type of baseload. So forget about combining nuclear with wind + solar. They don't mix any more than oil and water do.
  • 100% renewable power peaks are not just an accomplishment, but also a challenge. Here, the easy part ends and the hard part begins. We still only have 20% wind and solar on the German grid. Moving further means peaks of 120% and more.

The nuclear phaseout will help push off baseload by the end of 2022. Then, storage will increasingly be needed (starting with power to heat, not batteries).

Keep checking Agora's website to see how the guesstimate develops.

    I'll try to fix the link: http://dlf.ua/en/how-much-could-be-earned-through-green-energy-2/ Renewable energy is really worth investing in.

    Wish Ukraine was more like Germany when it comes to renewables, yet, we're trying to make it better: http://dlf.ua/en/how-much-could-be-earned-through-green-energy-2/

    100% renewable power? Is it possible? I'm confused -- could someone explain it to a noob like me? :)

    Power to heat, particularly if using air or ground source heat-pumps is much cheaper than batteries at current battery costs. Given that low temperature heating for space heating, hot water and a lot of intermediate industrial process heat can easily be supplied from hot water, storage of heat over hours or even days is very inexpensive possible.

    (sorry for the double posting)
    About the French atom fleet:
    A record number was out of order on the 15th of May 2016, 33 of the 56 'operating' reactors were either throttled down or stopped producing according to EdF's remit page:

    The spot power prices at the EEX confirm that the base producers are the culprit to be blamed for negative prices:

    The average power price was €12.-/MWh , how would it have looked if all atom power plants there had been operating?

    " Wind and solar cannot produce negative wholesale prices. Wind farms and solar arrays will never pay you to take electricity off their hands they will simply curtail."
    Checking the prices at the EEX powerexchange this is indeed so.
    During the 15 of May (the 100% - day) spot prices in Germany where higher than those in Switzerland. It looks as if the German power producers have curtailed their plants more than the Swiss producers.

    Switzerland has compared to Germany very little wind and PV power installed.
