Greece and Bulgaria emerged as the key price-moderating markets in Southeast Europe during Week 25. Greece’s average wholesale electricity price fell by 6.6% to €85.50/MWh, while Bulgaria’s average price declined by 6.4% to €87.58/MWh. During the same period, both countries strengthened their export positions, affecting regional market dynamics.
Renewables and gas flexibility behind Greece’s lower prices
In Greece, the decline in prices was supported by stronger renewable generation and flexible gas-fired output. Variable renewable output increased by 18.2%, with wind generation rising by 37.5% and solar production increasing by 11.4%. Gas-fired plants provided balancing flexibility while the absence of lignite generation did not stop prices from moving lower.
This mix kept Greece among the more competitive electricity markets in the region during a week when several neighbouring countries faced upward price pressure.
Bulgaria’s solar-led drop despite hydropower decline
Bulgaria recorded a similar price outcome through different drivers. Higher solar generation and stronger export activity helped reduce domestic prices even as hydropower production fell by 39.4%. Net electricity exports rose by 91.8%.
The export increase reinforced Bulgaria’s position as a major supplier of electricity to neighbouring markets and a contributor to regional supply security.
Export pocket indicators for Greece–Bulgaria corridor
Both countries have the potential to continue moderating regional prices during periods of strong renewable generation. The ability to do so depends on factors including reduced solar output, weaker wind conditions, hydropower constraints, generation availability issues and transmission bottlenecks.
For traders, the Greece–Bulgaria corridor supports opportunities based on price spreads versus Romania, Serbia, Hungary and Italy. Industrial consumers can use these markets as a benchmark for competitively priced regional supply.
Renewable energy developers can monitor how higher solar and wind output affects local pricing alongside export opportunities through cross-border participation. An export pocket watch should track price spreads, cross-border flows, solar and wind generation, hydrological conditions and interconnector availability.
