The new Finnish nuclear reactor, that increased their nuclear capacity by 50%, has replaced virtually all (formerly Russian) natural gas in their power mix.
They will realize: just in time

This year, on average, the Netherlands experiences almost 100 minutes per day negative power prices.
In 2023 this was 50 minutes/day.

For decades, in the area Rotterdam - Antwerp - Maastricht - Lille - Dunkirk, a commercial pipeline system is in use for hydrogen (red), oxygen (blue) and nitrogen (green).
Total length more than 2000 km!

Fuel demand for international shipping ('bunkers') is not included in the national CO2 emissions and neither in the calculation of the percentage of renewables of a country.
For the EU27 (often 'forgotten') fuel demand for international shipping equals 4,5% of the entire final energy consumption.
For the Netherlands and Belgium, this percentage is about 25%. For the island of Malta it is even 300%.

This year, the Dutch CO2-emission per inhabitant equals that in 1956.
Since 1956, the Dutch population has grown by 66%.

Somehow, there is a linear relation between the average daily power price and the fraction of solar and wind in the production mix.
This line crosses zero at 100% solar and wind.
I discovered this relation back in 2017, with much less solar and wind in the Dutch mix, and it still holds.
Is this also true for other countries?

My judgment about the declining Monthly average CO2-emission of Dutch power generation.
Nowadays, In the Netherlands, solar and wind have an average market share close to 50%.

After a dip, due to extreme gas prices, the usage of LNG as bunker fuel for shipping (port of Rotterdam) increases significantly.
LNG has significant environmental benefits compared to fuel oil and a modest CO2 advantage. See graph.

In comparing solar energy in NW-Europe and California, it is essential to know that San Francisco is the same lattitude as southern Spain ('Sevilla').
Consequenty, while the difference between (monthly) solar production in December and June is about a factor 10 in NW-Europe, it is only about a factor 2 in California.

The fraction of solar and wind in the Dutch powermix is now 45%. A year ago, it was 37%.
With this y-o-y increase, the Netherlands is well on its way to the planned fraction of 85% solar and wind in 2030.

The Dutch power mix in Q2 2024. Any remarks?

This year, free electricity, or even negative prices, may occur on almost all hours in a week, with the exception of the evenings.
Due to lower demand, they occur mainly in the weekend.s.
These are data from the Netherlands, similar results can be obtained from other European countries.

The power of EU legislation.
Between 1990 and 2021, emissions of nitrogen oxides in EU27 have been cut by almost 2/3.
All EU countries have contributed significantly to this achievement.

This year, on average, about 30% of Dutch power consumption is produced by onshore and offshore wind turbines in the Netherlands.
So far, the majority of Dutch wind power came from onshore turbines; from this year onwards, offshore will be the main contributor.

Since 1990 industrial air (pollutant) emissions in the Netherlands have declined significantly. This decline continues, on average, these emissions are now 30% lower than in 2010.
I expect similar results in other Europen countries, due to similar legislation and technological progress

Tomorrow 'douze points': for more than half a day, electricity (day ahead) in large parts of Europe is (almost) free and/or has a negative price.
The example is from the Dutch market.

My new blog (in Dutch) about the electricity market. Many still act as if renewable power is scarce in NL/Europe. In reality, and certainly from 2025 on, renewable power production is often much higher than power demand with zero/negative prices and massive curtailment of solar and wind as result.

Geopolitics at work.
Russia wants to sell a significant fraction of its natural gas destined for Europe to China.
China is willing to buy, but wants a very significant price reduction compared to what Europeans were paying.
The negotiations are stalled now, according to this news article.

Last week, approximately 70% of Dutch electricity demand came from renewable sources.

Tomorrow afternoon, May 11th, electricity is for free at the wholesale level in a region from Spain to Finland.
Exceptions are UK and Poland. But since these countries invest in a significant expansion of solar and wind as well, they will follow soon.
https://sfo3.digitaloceanspaces.com/cdn.mastodon.energy/media_attachments/files/112/416/568/589/471/608/original/57af9a857c8cb2f5.png

In 2024, so far, there have been 85 hours with wholesale power prices in the whole ARRRA region (DE/BE/NL) below 1 €/MWh, indicating that solar and wind in these hours outpace electricity demand.
Since in the coming years, solar and wind will grow much faster than electricity demand years, an increase of such hours may be expected.
