Greek net exports increased while Bulgaria’s export surplus narrowed in the week to 20 September. Greece raised net electricity exports to 126.87 GWh as demand and gas-fired generation fell. Bulgaria still recorded a larger regional net export balance at 247.47 GWh, despite a weekly decline.
In Greece, net exports increased from 91.93 GWh to 126.87 GWh over the week to 20 September. Electricity demand dropped by 9.32% to 1,019.36 GWh. Gas-fired generation declined by 12.46%, while wind output rose by 10.3%. Solar generation fell by 9.2%, partly offsetting the wind increase.
Bulgaria’s net export balance stood at 247.47 GWh, down 9.90% from the previous week. Hydropower output fell by 28.51% to 37.61 GWh, while total thermal generation was broadly stable. Bulgaria’s weekly day-ahead price decreased by 2.93% to €162.07/MWh. Greece averaged a weekly day-ahead price of €155.42/MWh.
Demand, generation and price changes across the two markets
The export positions were reached through different shifts in demand and generation. In Greece, higher exports coincided with lower consumption and a decline in gas-fired output. Bulgaria maintained a much larger surplus even as reduced hydropower contribution aligned with a smaller export balance.
Implications for cross-border trading volumes
For cross-border traders, the key question is whether the observed export volumes persist as autumn demand changes. One week indicates the direction of flows, but hourly generation patterns and border capacity will determine where electricity can be sold.
