Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

I used to enjoy reading his articles here years ago and it's nice to see one of his articles get so much attention.

The real lesson about the end of nuclear in Germany

Frontpaged with edited link - Frank Schnittger

Thx for the tip ... indeed, excellent insight as always. Not just on fossil fuels 😄

The real lesson about the end of nuclear in Germany The end of baseload is coming  | by Jérôme à Paris |

The end of baseload is coming

Is that what you usually hear? That replacing nuclear (a lot of it) by (a lot of) renewables will actually reduce fossil fuel use in the power sector?

And yet it is the main lesson here. Lignite will be phased out in the next 10 years, and Germany will thus soon become a baseload-free system, dominated by renewables (which will then be well above 50% penetration, probably close to 60%).

And do you hear about how German is a larger exporter of power than France? And, even more significantly, that its exports are at a higher price than France's (ie that they produce more at times that are better correlated to demand than France)? And that it is imports from Germany that allow France to go through peaks of high demand, because baseload cannot produce more than what it usually produces (that's the whole point of baseload)?

Germany exports wind when it can, and flexible generation otherwise. Upward flexibility can only come from flexible plants that are switched off a lot of the time, and turned on only in times of need. So yes, Germany has a lot of gas-fired plants, and a lot of coal-fired plants, but they are actually used very little - only when demand (including from France) is very high and renewables supply is very low - which does happen, but not that often anymore. Fossil fuel power plants are relatively cheap (and made in Europe), and if they are used rarely they don't emit a lot of carbon dioxide.

Why baseload power is doomed | By Chris Nelder - March 28, 2012 |

A persistent myth about the challenges of integrating renewable power into the grid is that because solar and wind are intermittent, grid operators need to maintain full generation capacity from "baseload" plants powered by coal and nuclear. Recent real-world data and research shows that not only is this not true, but that baseload capacity is fundamentally incompatible with renewables, and that as renewables provide a greater portion of the grid's power, baseload generation will need to be phased out.

That is because the removal of Russian gas have made the system jump from suppliers bidding to sell the last kWh to consumers bidding to buy the last kWh.

Nothing new for those who has seen prices do these kinds of jumps before.

As nuclear production increases, so does EU defined Green energy. False notions using percentages instead of absolute values.

So the US blew up Nord Stream pipelines and Western Europe suffers with strong savings Russian gas ... MAGA.

The EU channels me

The new energy market paper gets stuff right

The draft of the electricity market reform has leaked and it is music to my ears...

    Power purchase agreements and contracts for difference not only provide consumers with stable prices, they also give renewable energy suppliers reliable revenues. This lowers their financial risk and greatly reduces their cost of capital. This creates a virtuous circle where stable revenues lower costs and boost demand for renewable energy.


    Where Member States decide to set out direct price support schemes for new investments in low carbon, non-fossil fuel electricity generation to achieve the Union's decarbonisation objectives, they should be structured to include, in addition to a revenue guarantee, an upward limitation of the market revenues of the generation assets by way of two-way contracts for difference or other equivalent contractual formulations.

TenneT and National Grid collaborate on proposed first-of-a-kind Anglo-Dutch electricity link

TenneT and National Grid have today  announced plans for a first-of-its-kind electricity link that will connect offshore wind between the Netherlands and the UK.  
LionLink, which was included as a key project in today's North Sea Energy Declaration, could connect Dutch wind farms to the electricity grids of both countries via a subsea high voltage electricity cable, called a multi-purpose or hybrid interconnector. The development would be the first of its kind for the UK and the Netherlands, and the first step towards an integrated electricity grid in the North Sea.

Europe's largest nuclear plant starts operating in Finland

Fourth reactor at Georgia nuclear plant completes test phase, 1 May
That means the unit of the Atlanta-based Southern Co. can start loading radioactive fuel into the reactor once it completes construction documentation and gets approval from the U.S. Nuclear Regulatory Commission.
Units 3 and 4 at Plant Vogtle are the first new reactors built from scratch in decades in the United States. The first two reactors have been generating electricity at Vogtle for decades. A third and a fourth reactor were approved for construction at Vogtle by the Georgia Public Service Commission in 2009, and the third reactor was supposed to start generating power in 2016.
Georgia Power owns a minority of the two new reactors. The remaining shares are owned by Oglethorpe Power Corp., the Municipal Electric Authority of Georgia, and the city of Dalton. Oglethorpe and the Municipal Electric Authority of Georgia would sell power to cooperatives and municipal utilities across Georgia, as well in Jacksonville, Florida, and parts of Alabama and the Florida Panhandle.

Georgia Power's 2.7 million customers are already paying part of the financing cost, and state regulators have approved a monthly rate increase of $3.78 a month as soon as the third unit begins generating power. The elected Georgia Public Service Commission will decide later who pays for the remainder of the costs, including the fourth reactor.

Zaporizhzhia is the largest nuclear power plant in Europe, with six 950 MW reactors for 5700 MW nameplate capacity. It remains to be seen if it will ever reach that capacity again (and in which country).


The Olkiluoto plant consists of two boiling water reactors (BWRs), each with a capacity of 890 MW, and one EPR type reactor (unit 3) with a capacity of 1,600 MW.[1] This makes unit 3 currently the most powerful nuclear power plant unit in Europe

... i.e. it's the headline that's wrong : the EPR is the most powerful nuclear reactor in Europe.
The plant, at 3290 MW for its 3 reactors, is far from being the biggest nuclear power plant in Europe. I have never seen a nuclear reactor called a "nuclear power plant unit" before. Where do they get these journalists.

In France, Gravelines (practically in Belgium), Paluel (in Normandy) and Cattenom (practically in Luxemburg) have a higher nameplate capacity, at 5200 MW, than the Finnish plant. I have worked at all three. Oh, and there a bunch of other French plants at about 3600 MW, most of which I have also been to. So Olkiluoto comes in 11th in Europe.

Given the current problems of corrosion under constraint which have contributed about as much as the Russian gas crisis to the explosion of electricity prices in Europe, one reactor at Cattenom and two at Gravelines are currently under maintenance. But in terms of current production, Cattenom is the top in Europe, at about 3600 MW.
