Greece and Bulgaria emerged as the key price-moderating markets in Southeast Europe during Week 25, reinforcing their importance as regional balancing and export hubs. Greece recorded a 6.6% decline in average wholesale electricity prices to €85.50/MWh, while Bulgaria’s average price fell by 6.4% to €87.58/MWh. At the same time, both countries strengthened their export positions, highlighting their growing influence on regional market dynamics.
In Greece, the decline in prices was largely supported by strong renewable energy performance and flexible gas-fired generation. Variable renewable output increased by 18.2%, driven by a substantial 37.5% rise in wind generation and an 11.4% increase in solar production. Gas-fired plants provided the flexibility needed to balance the system, while the absence of lignite generation did not prevent prices from moving lower. This combination allowed Greece to remain one of the more competitive electricity markets in the region during a week when several neighbouring countries experienced upward price pressure.
Bulgaria followed a different path but achieved a similar outcome. Higher solar generation and stronger export activity helped lower domestic prices despite a significant 39.4% decline in hydropower production. Net electricity exports increased by an impressive 91.8%, confirming Bulgaria’s role as a major supplier of electricity to neighbouring markets and an important contributor to regional supply security.
Looking ahead, both countries have the potential to continue acting as lower-priced export pockets during periods of strong renewable generation. However, this position is far from guaranteed. Reduced solar output, weaker wind conditions, hydropower constraints, generation availability issues or transmission bottlenecks could quickly limit their ability to moderate regional prices.
For traders, the Greece–Bulgaria corridor presents valuable opportunities to capitalize on price spreads relative to Romania, Serbia, Hungary and Italy. For industrial consumers, these markets provide an important benchmark for competitively priced regional supply. Meanwhile, renewable energy developers can observe how strong renewable output can suppress local prices while simultaneously creating opportunities through exports and cross-border market participation.
An effective export pocket watch should focus on key indicators such as price spreads, cross-border flows, solar and wind generation, hydrological conditions and interconnector availability. Greece and Bulgaria should not be viewed merely as lower-priced markets; they increasingly serve as strategic balancing zones that help stabilize the broader Southeast European electricity system.
