We need to talk about Denmark's enormous reliance on importing electricity!. A grid with a high penetration of wind and solar comes with a backside. Often, for days at a time, imports account for more than 50% of the national electricity demand. A short thread 🧵

I don't see how more offshore wind solves our energy problems. We are looking at increased blackout risks from periods of under-supply, and when renewable output is high and the grid gets unstable. The prices are increasingly volatile and we are still dependent on biomass and gas.

The Danish government now wants to subsidize 3 GW of new off shore wind, after a failed tender last year with 0 bidders. They demand subsidies. With 1 GW coming up in 27/28 from the project Thor, it looks very questionable how we can use 3 GWs more.

The reason for the declining production from offshore wind is curtailment. Solar is eating away at all other power sources, and especially off shore wind turns off in response to the oversupplied market.
We've just seen five consecutive days with many hours of negative prices and off-shore wind turning off in response. Is more wind power really what we need?

Offshore Wind Capacity Factors in Denmark are falling fast. In less than one year, it has dropped to below 39% for several large wind farms. Last week, the government decided to subsidize more offshore wind, including coverage of lost revenue from curtailment

This is the Nuclear Power plant Olkiluoto in Finland. Last year, it produced more energy than all the wind-turbines in Denmark combined. We have the solutions. Implement them.

France has to pay renewable generators to curtail production if the system is oversupplied. The weather dependent energy sources flood the market with power that is not needed, destabilizing the grid, and are then compensated to stop it. There's something wrong with that.
A “very strained” power grid due to oversupply has forced French TSO RTE to trigger a rarely used and costly emergency balancing mechanism and to curb renewable output, analysts told Montel.

@DanJoergensen 25% of European power comes from nuclear, and it must increase. More than half of the EU is in a literal Nuclear Alliance. You fought hard against nuclear as the Danish minister for Energy. But now, you're responsible for all of Europe, so this anti-nuclear mentality has to go!.

If you're still in doubt whether our European Energy Commissioner is still a no-good anti-nuclear 100% renewabro:. "We are a European community of wind turbines, solar panels, and geothermal generators.". You have to include nuclear as well @DanJoergensen!.

This year marks the 40th anniversary of Denmark's decision to exclude nuclear energy. That same year, Sweden surpassed what Denmark has produced TODAY, in terms of cumulative amount of green energy per capita. If you hear that Denmark is leading in green energy, it is wrong.

I want reliable, stable power. Not this memecoin ahh shit with prices and reliability flying up and down. Crazy to think we payed hundreds of billions of Euros for this system, that keeps getting more unreliable and expensive for consumers. I want power like in 2017.

The power price used to be distributed over a low range of values. Now prices can vary, even during one day, several hundred Euros (pr MWh). Notice also how there is a peak at 0 that spreads into the negative: we experience many negative price hours but also very high price hours.

The price of electricity in Europe has increased a lot the last five years, we all know that. What deserves more attention in my opinion is how much more volatile the market has become. Power prices are way more spread out now than compared to before the energy crisis. 👎

Despite promises of 'Technology Neutrality', the new EU Commission continues to completely neglect Nuclear Energy. The Clean Industrial Deal is nothing but old wine in new bottles; a renewables only focus, which is what caused this European energy crisis in the first place.
A strong economy, competitiveness, and a clean future—we're making it happen. Europe’s rich industrial heritage has a bright future ahead. The #CleanIndustrialDeal is our plan to support 🇪🇺 industry to make it sustainable, competitive, and future-ready ↓

Can we talk about how the first thing new EU Energy Commissioner has done is throw almost a billion € at his failed prestige project Energy Island Bornholm, something he worked for as energy minister in Denmark?.Already 8 years wasted and hundreds of millions € down the drain

Here's an explanation of Capture Rate, and why a declining capture rate is a bad thing.
@GeoMacroni The Capture Rate measures how much of the average spot market price is 'captured' or realized. It is falling for solar, because it produces simultaneously in all EU, pushing prices down during the day, and thus their profits. They cant get the high prices at evening (no sun).
