#GermanEnergyFact 37: 🇩🇪 is getting really serious about renewable energy sources - at least in terms of the law.

Behold §2 of the new 2023 Renewable Energy Sources Act (EEG), under the headline "Special importance of renewable energy sources":

The construction and operation of renewable energy plants and their associated ancillary facilities are in the
▶️overriding public interest◀️ and
▶️serve public safety◀️.

Let's see what it's worth!

Back from holidays, I realize that I'm still one post behind schedule, so here is #GermanEnergyFact #36 (which also concludes my mini series of fun facts about EEG 2000 and 2023):

How often does the expression "coal phase-out" (Kohleausstieg) appear in different versions of the 🇩🇪 Renewable Energy Sources act (Erneuerbare-Energien-Gesetz, #EEG):

▶️ First EEG version of the year 2000: 0️⃣
▶️ Current EEG of 2023: 5️⃣

@wpschill
Thank you for your #GermanEnergyFact thread!
What do you think,, going forward in the year, could it be a good idea to split the hashtag into monthly threads?
Scrolling through the posts and replies should become a bit confusing, what, with Mastodon's way of displaying all replies at the end of the thread, without apparent tie to their parent post?

Woah, we're already in the second month of your favorite thread of daily German #energy facts! 🎉

So here is #GermanEnergyFact #32 - the first of a series of fun facts on #renewable energy legislation in 🇩🇪 :

▶️ How often word variations of the expression "market" (Markt) appeared in the first German Renewable Energy Sources act #EEG of the year 2000: 3️⃣

▶️ How often variations of "market" are mentioned in the current 2023 version of the same law #EEG: 1️⃣ 7️⃣ 1️⃣

#GermanEnergyFact #31: more on market values of #solar #PV in 🇩🇪

Hope you're not bored yet, but here is another graph which I find interesting, focusing on PV market values relative to spot prices:

▶️ Market values are relatively high in winter, partly >100% (but production is very low in these months)
▶️ In summer, they decrease because of the merit order effect
▶️ Values also decrease over time with increasing PV penetration, some call it "cannibalization effect"

Data: https://www.netztransparenz.de/EEG/Marktpraemie/Marktwerte

#GermanEnergyFact #30: more on market values of #renewables in 🇩🇪

While the last post showed *absolute* values, here are monthly market values *relative* to spot prices since 2018:

▶️ In general: market value of PV > offshore wind > onshore wind
▶️ Solar market values peak in winter.
▶️ The general pattern has been quite persistent, even during the COVID pandemic.
▶️ Only in mid 2022, where spot prices peaked, #wind market values were above #PV.

Data: https://www.netztransparenz.de/EEG/Marktpraemie/Marktwerte

#GermanEnergyFact #29: more on market values of variable #renewables in 🇩🇪

I thought, let's stick to this topic for a while. So here is a view on absolute monthly market values of #wind power and #solar #PV since 2018

▶️ Both spot prices and market values of renewables hit a historic low in 2020 during the pandemic.
▶️ Since mid 2021, market prices massively increased, largely because of higher gas prices.
▶️ Wind and PV market values largely followed this trend.

Data: https://www.netztransparenz.de/EEG/Marktpraemie/Marktwerte

Since I'm still a day behind, here comes another one right away, #GermanEnergyFact #28: average yearly market values of #wind and #solar power in 🇩🇪 since 2020

▶️ Market values generally followed the exploding market price.
▶️ There seems to be increasing "cannibalization" of wind power.
▶️ I don't see why the market value of PV (relatively) increased in 2022. As the monthly values also look differently, there may be a data error. Anyone who knows more about this? @aurelwuensch @marcowuensch

#GermanEnergyFact #27: market values of variable #renewables 2022

2022 saw not only record-breaking electricity prices, but also extraordinary market values for #wind and #solar. Average spot price and market values:

▶️ Solar #PV: 22.3 ct/kWh (95% of average prices)
▶️ #Offshore wind: 18.3 ct/kWh (78%)
▶️ #Onshore wind: 16.3 ct/kWh (69%)

Data: https://www.netztransparenz.de/EEG/Marktpraemie/Marktwerte

Hm, it seems I forgot to post a #GermanEnergyFact yesterday. How come no one noticed? 😉

So, here is #GermanEnergyFact #26: remuneration vs. market value of #solar #PV in 🇩🇪

▶️ 5.8 ct/kWh: strike price for utility-scale solar in the last auction (Nov 2022)
▶️ 7.1 ct/kWh: current feed-in tariff < 40 kW
▶️ 10.9 ct/kWh: current feed-in tariff < 40 kW in case of full grid feed-in
▶️ 22.3 ct/kWh: average yearly market value of solar PV in 🇩🇪 2022 🤯

#GermanEnergyFact #25: remuneration for utility-scale solar #PV

While the FIT for rooftop PV installations <40kW in 🇩🇪 is currently 7.1 ct/kWh (or even 10.9 ct/kWh in case no electricity is self-consumed), remuneration for utility-scale PV is markedly lower. In Nov 2022, the last auction brought an average strike price of 5.8 ct/kWh.

Utility-scale PV operators receive the difference between this price and the average monthly market value of all PV plants as a premium.

#GermanEnergyFact #24 ctd.

So we are currently trying to incentivize grid feed-in of solar #PV via higher feed-in tariffs to make it more attractive compared to self-consumption.

Fun fact: around 15 years ago, we had the opposite situation: self-consumption was not profitable (retail prices were lower and FITs were very high), so in 2009 a 25 ct/kWh bonus was introduced for self-consumed electricity.

The people who locked this in for 20 years must be really happy today...

#GermanEnergyFact #24: A bit more on feed-in tariffs for rooftop #solar #PV

In August 2022, the FIT for new rooftop PV installations <40kW in 🇩🇪 *increased* again, from 6.06 ct/kWh to 7.10 ct/kWh, or to even 10.90 ct/kWh in case all electricity is fed to the grid and nothing is self-consumed.

The latter is intended to provide an incentive to install the largest possible systems on the entire roof area and not go for smaller installations oriented at maximizing the self-consumption share.

#GermanEnergyFact #23: Feed-in tariffs for rooftop #solar #PV 💶 ☀️

Feed-in tariff for new small-scale rooftop PV installations <30kW in the year 2004:
57.40 ct/kWh

Feed-in tariff for the same new installation in July 2022:
6.06 ct/kWh

Note: The respective feed-in tariffs are granted for 20 years after installation. And both are in nominal prices - i.e. the degression in real terms has been much higher than this.

#GermanEnergyFact #22: #renewable #electricity generation in 🇩🇪 since 1990

I'm concluding my week on #renewables with a time series of renewable electricity generation.

▶️ Early 90s: < 20 TWh, most of it hydro power.
▶️ 2022: 253 TWh, more than 13 times as much than 1990.
▶️ Most of the growth came from #wind and #solar power.
▶️ This number has to grow >1000 TWh by 2045 in most relevant climate-neutrality scenarios.

#GermanEnergyFact #21: complementary monthly generation of #wind and #solar #PV

Today, no hard numbers, just visuals: monthly generation from PV (yellow) in 🇩🇪 is relatively high between around April and September, while generation from wind power (dark & light blue) is above-average between around October and March. Nice seasonal balancing (on a monthly basis).

(sorry, again a German graph - but I'm sure you get the point without reading the legend)

#GermanEnergyFact #20 ctd.

▶️ #Renewable #electricity generation in 🇩🇪 was 8% higher in 2022 compared to 2021.
▶️ Main reasons: it was much windier 💨 , and there were more sunshine hours ☀️ . In addition, #PV capacities also increased (see #GermanEnergyFact #16).
▶️ The share of variable renewables (wind & PV) in overall renewable generation was 77% (!).
▶️ You can expect this share to increase further in the future, as all the growth in renewable electricity will come from #wind and #PV.

#GermanEnergyFact #20: #renewable #electricity generation

Earlier this week, I talked about renewable generation capacity (GW) in 🇩🇪 (facts #16-18). #AGEE-Stat also provides up-to-date data on renewable electricity generation (TWh): https://www.umweltbundesamt.de/themen/klima-energie/erneuerbare-energien/erneuerbare-energien-in-zahlen/monats-quartalsdaten-der-agee-stat#Quartalsdaten (sorry for the German chart, no time for translation today)

▶️ Overall renewable electricity generation in 2022 was a bit above 250 TWh, the highest value ever. The trend is good - but we need much more to make the #Energiewende really happen
