On Sunday 12 May, in the Netherlands, I estimate that 65% of all onshore wind production had to be curtailed.
Also large curtailments will have taken place for large scale solar and offshore wind.

Note: real time onshore wind data in ENTSO-E are from wind parks connected to the TSO network. These are mainly large wind parks.
Since most other wind parks in the NL are operated, on behalve of the owners, by companies with 24/7 dealing rooms, I expect a similar behavior for those parks.

It was a matter of overloading.

In the afternoon, according to Energieopwek, there was potentially 24 GW power production by solar and wind alone, while the market could only absorb half of it.
The fact that zero and even negative prices occurred, showed as well that there was considerable overloading.

Tomorrow day-time, everywhere in Europe negative power prices.

Various European countries have similar amounts of hours of such prices so far this year. An exception is Greece.

Tomorrow from 12 AM to 3 PM, very low prices, below -100 €/MWh occur in a large area comprising the Netherlands, Germany and Belgium up to Switzerland, Austria and Hungary.

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.

On novel network tarrifs for households, to stimulate them to use the scarce, expensive, capacity with care.

Prima suggestie!

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.

@FabianLaasch
It is not a big problem in my view. One of the consequences is that, during these hours, efficiency hardly matters, while network capacity does.

While some EU-countries treat 'energy' as a 'basic need' and apply the low VAT rate, others treat energy as a 'luxury good' and apply the high VAT rate.

@bolzano
No, the mentioned reduction deals with the energy taxes which come on top of the 21% VAT and, by the way, would be by far the highest in Europe without the reduction mentioned.

Significant variations in network costs for households (in €ct/kWh) among West-European countries.
Does anybody know a study with an explenation?

In April 2024, the Netherlands, experienced on almost all days for some hours a more than 100% contribution of solar and wind to the national power demand.

Overproduction of solar and wind electricity was either exported, up to 50% of national demand, or had to be curtailed for technical or commercial reasons.

BM_Visser, to random Dutch
@BM_Visser@mastodon.energy avatar

Until today, the Netherlands has had 105 hours with negative power prices this year.

Such prices occur when power production by solar and wind in the Netherlands exceeds national demand + net exports.

BM_Visser, to random Dutch
@BM_Visser@mastodon.energy avatar

In the last 12 months, the average percentage of renewables in the Dutch electricity demand was 52%.

Growth mainly due to a significant increase of offshore wind and solarPV capacity.

Reduction in biomass is caused by the reduced utilisation of Dutch coal-fired power stations and hence, there was less co-firing of biomass.

@adnan
This is based on national consumption.
The Netherlands has a 5-10% net export of electricity produced. Hence, the percentage based on production would be 5-10% less.

Tomorrow May 1st, a national Holiday in many European countries.
As a 'bonus', electricity is free* between about 10 AM and 5 PM. Also in Spain (not on the map) and even in Poland.

*excluding taxes and not for those, who have fixed rates..

So far the Netherlands has experienced 92 hours with a negative (day ahead) power price this year.
At the end of April in 2023, it were just 52 hours.
In the Netherlands, solar and wind increase by about 20% per year, while power demand is about stable.

@Schneebesen
In my view, in 2023, Solar PV capacity innNL reached a critical level from which it often ‘outperformed’ Dutch power demand (minus must run) including export potential.

The contribution of solar, onshore and offshore wind to Dutch power demand in March 2024.
Negative values are to be compensated by exports (up to about 7 GW) or by curtailment.

Although Germany, Belgium and the Netherlands have had different climate policies since 1990, their greenhouse gas emissions follow more or less the same path.

@BM_Visser@mastodon.energy avatar

In 2024, many European countries experience 2-3% hours with negative power prices.
Only Spain and Portugal experience about 20% hours with power prices close to zero (in 2024). Partly this is due to abundant hydro this year at the Iberian peninsula
(1 €/MWh = 0,1 €ct/kWh)

BM_Visser, (edited ) to random Dutch
@BM_Visser@mastodon.energy avatar

In 2024, until now, the Netherlands has about 3% of all hours negative day ahead power prices. In 2023, this was 2%.
Negative prices can be seen as an anomaly of the power system, but appear for 2-3% of the time, almost everywhere in Europe in 2024.
I expect (and have predicted that years ago) that this phenomenon will become a common feature in Europe from 2025 onwards.

Nee. Gas kan gemakkelijk en goedkoop in grote hoeveelheden worden opgeslagen, dus zal niet snel een negatieve waarde krijgen.

Negatieve stroomprijzen betreft overaanbod uit wind en zon. De spaarzame gascentrales die dan nog draaien maken sec verlies op verkochte elektriciteit, maar verdienen hun geld met dienstverlening aan TenneT of anderen die flex nodig hebben en/of worden 'warm gehouden' met het oog op de avondpiek wanneer wel (zeer) winstgevend kan worden geproduceerd.

@mfierst

Ze zijn gekoppeld op (nog) heel veel uren dat er onvoldoende zon en wind (en kernenergie) is om in de stroomvraag te voorzien, inclusief effect import/export, waardoor gascentrales de marginale MWh produceren.
