In the third week of May, negative or zero hourly prices were registered in most of the European electricity markets, especially during the weekend. In the Nord Pool market, the value of -€5.67/MWh registered during an hour on Sunday May 21, is the lowest one in history. For the week as a whole, prices decreased in every market, due to the decrease in demand and gas prices, and also to a higher solar and wind energy production than that of the previous week in several markets.
