Greece increased its net electricity exports in the week ending 20 September, while Bulgaria remained the region’s largest exporter despite a reduction in its export surplus.
Greek net exports rose from 91.93 GWh to 126.87 GWh during the week. At the same time, electricity demand declined 9.32% to 1,019.36 GWh, while gas-fired generation fell 12.46%. Wind generation increased by 10.3%, partly compensating for a 9.2% decline in solar output.
Bulgaria recorded a net export balance of 247.47 GWh, although this was 9.90% lower than in the previous week. Hydropower generation fell 28.51% to 37.61 GWh, while total thermal generation remained broadly stable. Bulgaria’s average day-ahead electricity price declined 2.93% to €162.07/MWh, compared with €155.42/MWh in Greece.
The two countries therefore recorded stronger or sustained export positions for different reasons. Greece benefited from lower demand and reduced gas-fired generation, alongside higher wind output. Bulgaria continued to maintain a considerably larger export surplus, despite weaker hydropower production.
For cross-border electricity traders, the key issue will be whether these export flows remain sustainable as autumn demand and generation patterns change. Weekly balances provide an indication of market direction, while hourly production profiles and available interconnector capacity will determine where electricity can ultimately be delivered.
