Greece increased net electricity exports by 52.83% to 208.38 GWh in the week to November 1, while remaining the lowest-priced of seven major regional power markets tracked by IENE. The figures came as generation and demand also changed during the week.
Greece’s weekly average day-ahead price reached €255.04/MWh, up €25.62/MWh. It was €32.22/MWh below Romania’s price and €6.72/MWh below Italy’s. Traders use the discount to assess whether supply from southeastern Europe can ease higher-priced markets to the north and west.
Wind generation increased by 193.9%, almost tripling, while solar output fell by 42.2%; combined wind and solar production rose by 7.2%. Hydropower production declined by 3.80%. Gas-fired generation increased by 13.40%, helping total thermal output rise by 10.38%. Electricity demand grew by 1.64%.
The combination of stronger wind generation, increased gas-fired output and higher net exports pointed to a substantial change in Greece’s regional supply role. However, lower prices and higher exports do not guarantee neighboring buyers can obtain Greek electricity at Greece’s clearing price. Available interconnector capacity and hourly price formation affect access to that supply.
