Last week, the Netherlands had, on average 4 hours per day with a negative day-ahead power price.

Until now, the Netherlands had 155 of such hours this year, compared to 65 last year in the same period, and 31 in 2022. A significant increase. We see this in most European countries.

The expansion of solar and wind occurs much quicker than the increase of power demand. Consequently, negative and near-zero power prices, with significant curtailment of solar and wind, will become more common.

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.

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.

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.

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.

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.

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, 27 days ago to random Dutch

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.

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.

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.

BM_Visser, 1 month ago (edited 1 month ago) to random Dutch

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.

Interesting distribution of power prices in NW-Europe, tomorrow afternoon, April 11th.

In Germany, there is significant sunshine and consequently, day-ahead electricity is almost free (€0,57/MWh).
In the Netherlands, it is cloudy and some drizzle is expected and consequently, the day-ahead electricity price is rather high (85,05/MWh).

The Dutch could have produced 24 GW from solar and wind this afternoon. However, with a national demand of about 13 GW and 6 GW export, significant solar and wind had to be curtailed.
This curtailment is not (yet) included in the app www.energieopwek.nl

For onshore wind, expressed in MWh/km2, the Netherlands is top in Europe.
For solar PV, one country harvests more energy per km2 than the Netherlands.
Do you know which?

BM_Visser, 1 month ago to random Dutch

In 2023, the Netherlands harvested more than 400 MWh of (onshore) wind energy per km2 of land (lakes included).

This was more than any other country in Europe; and probably as well in the world.

In 2023, the percentage of renewable electricity in the Netherlands has become higher than in the UK.

In the last 7 years, electricity production from solar PV and wind has been doubled.

In February 2024, EU natural gas demand was 23% (!) less than its 'pre-crisis' average in February 2017-2021.

Main causes are:
the relative warm weather;
lower industrial production due to high prices for natural gas, CO2 and power; and
the growth of wind and solar power.

Which EU country had the highest share of solarPV in its electricity mix in 2023?

Note: my guess was Greece, but I was wrong.

Preliminary data show that the Netherlands has surpassed 'World Champion" Australia with respect to solarPV capacity per inhabitant.

Since Australia is much more sunny than the Netherlands, its solar production per inhabitant exceeds the Dutch one significantly.

Last year, power demand in almost all EU countries decreased. On average, by 6%.

This had major consequences for the utilisation of coal and gas-fired generation, since these are the most expensive ones with regard to marginal costs. And so, less CO2-credits (ETS) were needed for th EU power sector.

Moreover, the decrease in the EU power demand boosted the percentage renewables, since hydro, wind and solar production is hardly affected by lower demand.
