AleaSoft Energy Forecasting attributed the broad decline to higher wind power generation alongside lower demand in some markets. In Italy, however, lower wind generation combined with elevated gas prices and higher CO₂ allowance prices contributed to an increase in electricity prices during this period.
AleaSoft outlook for week beginning September 21
For the week beginning September 21, AleaSoft Energy Forecasting expects electricity prices to rise in most analyzed European markets as wind power generation is expected to be lower . Prices are forecast to decline in Italy because wind generation is expected to increase . Gas price developments are also expected to remain a key factor influencing electricity prices across Europe during the fourth week of September .
