Drivers and next-week price outlook
AleaSoft Energy Forecasting linked higher electricity prices in most markets to lower wind power generation alongside falling gas prices. In Great Britain and Portugal, stronger electricity demand added upward pressure on prices. In Italy, higher wind generation combined with lower demand contributed to the decline in electricity prices.
AleaSoft forecasts that for the week beginning September 28 electricity prices are expected to rise across most of the analyzed European markets. Italy and Great Britain are identified as exceptions, with prices expected to decline in both markets.
