In Great Britain and Portugal, stronger electricity demand provided an additional upward pressure on prices. In Italy, by contrast, higher wind generation combined with lower demand contributed to the decline in electricity prices.
According to AleaSoft Energy Forecasting, price forecasts for the week beginning September 28 point to higher electricity prices across most of the analyzed European markets. Italy and Great Britain are the main exceptions, with prices expected to decline in both markets, AleaSoft reports.
