2022 was a sad and dramatic year. Energy was a main battlefront in the economic war of attrition between Russia and the pro-Ukrainian coalition.

A (highly selective) month-by-month recap 🧵
PRELUDE - SUMMER 2021
Russian manipulation of European natural gas markets started in summer 2021. Gazprom’s withholding of supplies marked the beginning of an energy crisis with substantially rising prices.
JANUARY 2022
While Russia concentrated more troops around Ukraine, it also ensured that EU gas storages remained empty, while teasing supplies through NordStream2.
FEBRUARY 2022
-After Feb24th, EU&US imposed technology-export sanctions that undermine the long-term prospects of Russia’s energy sector.
-But, RU banks involved in energy trading were excluded from financial sanctions by the West.
MARCH 2022
-US&UK announced bans on RU oil, coal and gas.
-To frustrate Western financial sanctions, RU demanded payments for gas in RUB. PL refused – and imports through Yamal stopped on 29Mar.
APRIL 2022
The 5th EU sanction package bans imports of RU coal that represented more than half of the EU-imports by that time.
MAY 2022
- around ½ of French nuclear reactors are offline sending 1Q23 peak-futures to 1000€/MWh.
- The European Commission published REPowerEU – acknowledging the need for faster RES deployment
JUNE 2022
-The 6th sanctions package on oil, oil products and related services was agreed to become active in Dec/Feb.
-On 14Jun Gazprom claimed that #NordStream1 was partly constrained (SiemensEnergy turbine in Canada)
JULY 2022
Summer droughts and problems on the French nuclear fleet force the European power sector to rely more on coal and gas.
Both wind and solar contribute to ease the situation.
AUGUST 2022
The coal embargo kicks in.

After Gazprom announces further maintenance works on NordStream1 the TTF-price peaks at more than 340 EUR/MWh by the end of the month.
SEPTEMBER 2022
-On the 2nd the G7 confirmed the price cap on Russian oil.
-On the 3rd Gazprom indefinitely suspended flows through NordStream
-On the 26th both branches of NS1 and one branch of NS2 were destroyed.
OCTOBER 2022
Strong gas demand reduction thanks to warm weather and behavioral change muted worries over the winter-supply situation.
NOVEMBER 2022
The energy policy debate shifts 𝗳𝗿𝗼𝗺 𝘀𝗲𝗰𝘂𝗿𝗶𝘁𝘆 𝘁𝗼 𝗮𝗳𝗳𝗼𝗿𝗱𝗮𝗯𝗶𝗹𝗶𝘁𝘆. As not all MS can fiscally shield consumers against skyrocketing energy cost, calls for market interventions get louder.
DECEMBER 2022
-Price 𝗰𝗮𝗽 for all RU crude oil exports and EU embargo on imports of RU crude kicks in.
-EU sets 𝗰𝗮𝗽 for the TTF-gas price (180 €/MWh)
Please allow us to wish you a happy Christmas and relaxing end to what was a sad and dramatic year.
We are looking forward to a more positive 2023.

Hot-take on the EMD draft:

Given the discussions in 2022, the COM proposal is not a revolution. But it is not only window-dressing, either. Some provisions might kick-off structural shifts:

(some 20 tweets)
Supporting PPAs 1/2
-the guarantee-system is described as a new form of subsidy
-text already hints at the risk of lowering liquidity of more standardised markets
Supporting PPAs 2/2
-building a system on idiosyncratic contracts with many small players might also entail risks - can we make sure, that sellers do not sell more than they have
-allowing (national) state guarantees for PPAs might lead to a fragmentation of the internal market

A 🧵on the cover of the #MarketDesignConsultation. The bullet points are my summary of the text, and my comments are in brackets.

[The document seems to have had some last-minute changes, given some word duplications and reference to earlier parts that do not exist]

1/
Causes
•High gas prices due to Russian gas withholding
•increasing energy demand after Covid
[Lack of hydro and French nuclear not mentioned even though that shortfall represented 7% of EU power generation in 2022]

Problem Description
•high prices
•Risk to SoS

2/
Current crisis policies
•Reduce consumption (mentioned 3x)
•Roll-out RES
•Secure alternative supplies
•Temporary state-aid framework
•Gas storage regime
•« EU implemented … Price-limiting regimes to avoid windfall-profits in elec&gas» [what are those ?]

The "Iberian exception" could be a substantial draw on scarce gas supplies!

German power plants would in specific situations use TWICE as much natural gas, if the gas price were subsidized from 150€/MWh to 50€/MWh!

1/3
[thx to @c_heussaff for calculations!] ImageImage
We use @ewi_koeln's cool merit order tool, adjust the fuel cost assumptions to be roughly in line with current numbers and assume a situation with a residual demand of 50 GW.

tool: ewi.uni-koeln.de/en/publication…
2/3 Image
Under these specific assumptions, we have 18 GW of gas fired power plants running, instead of 8 GW.

As the additional 10 GW units that are only used at subsidized prices are less efficient, the gas burn is disproportionately higher.

Cher Jean-Michel, I am afraid you are right. As energy gets much more expensive certain production will become uncompetitive in Europe without additional subsidies.

I see two political questions: …

1/5
First, should we particularly support energy-and-trade-intensive sectors? This would keep their substantial energy demand high – resulting in much higher energy prices for all other industries.

2/5
Second, should we try to delay the adjustment process to allow for a smoother transition of value chains – or does this actually only extend the harm (of high prices) for everyone?

Gute Diskussion.
Meine Hauptsorge ist, dass wir mit dem jetzigen Plan in der schlechtestmöglichen Situation landen. Keine kurzfristige Einnahmereduktion für Putin, hohe eigene Kosten und der langfristige Ausstieg ist nicht glaubwürdig.
Beim Gas hat bisher nur Russland substantiell gehandelt. Die Taktik scheint gezielte Verknappung, aber gerade nicht vollkommener Stopp zu sein (würde ich auch bei Lebensmitteln so sehen).
Wenn das Argument, dass wir eh komplett aussteigen werden und in der Übergangszeit mit maximaler Obstruktion Putins leben müssen, stimmt, würden wir uns mit dem vorgeschlagenen Ultimatum nicht schlechterstellen.

NEW Study (in German):
We show that - if the right steps are taken to prepare - Germany can make it through next winter without Russian gas at manageable cost.

...
only diversification will not be enough
Reducing winter demand will be crucial.
