Lower wind power generation across most markets contributed to higher electricity prices despite declining gas prices. In Great Britain and Portugal, stronger electricity demand also supported prices. Italy followed a different pattern, with higher wind generation and lower demand contributing to the weekly decline.
For the week beginning September 28, AleaSoft Energy Forecasting expects electricity prices to rise across most of the analyzed European markets. Italy and Great Britain are the main exceptions, with prices forecast to decline in both markets, according to AleaSoft.
