The new 15-minute day-ahead auctions went live this week, marking one of the most significant changes in the European power market to date.

Yes very much so.

No power plant in the market always runs at 100% of capacity, yet with renewables we have always done that.

Commercial curtailment is the third major trend, shifting the way the power market works, after wind and solar changed markets forever.

Highest evening peak prices of the summer so far... heatwave is overheating the evening peak.

Belgian intraday power and balancing prices went extreme around 18:00 CET. Our direction forecast saw this coming well in advance. Pretty cool to have seen this 4 hours before gate closure. Screenshot is the volume forecast, including all historic forecasts.

DE: with downward aFRR capacity prices averaging around € 100/MW/hr for some of the night hours, I would not be surprised if day-ahead prices saw 1 or 2 negative hours for the night of Sunday to Monday. We seem to be on a similar track as last year for now.

When national grid reversed the #interconnectors that was also absorbed. 14 GW of export, 4 GW of nuclear curtailment and 3 GW of pumping. In GB we saw up to 4.5 GW of curtailment in wind assets, also showing off their flexibility.

Dual imbalance prices in Netherlands are a typical feature of the market, designed to discourage oscillations in balancing markets. They are a strong incentive for having a balanced position if the market is in turmoil.

Unfortunately, turmoil seems to be the permanent state of the market.

Sweden’s SE-2 region just passed Finland as the European region with the highest number of negative day-ahead hourly power prices in Europe in 2024. 714 hours with prices below zero… #electricity #powermarkets #negativeprices

Negative power prices, an interesting phenomenon in many European markets. Will the highest number of negative prices be in Sweden or Finland? And which regions see the highest number of hours with ‘free’ power?

In fact Spanish and Portuguese power is free (or cheaper) almost 10% of all hours in 2024!
