Greece entered the final week of May with an average day-ahead price of €86.77/MWh, down 0.7% week-on-week. The market ranked as the second-cheapest in Southeast Europe after Türkiye. Net electricity exports increased by 35.7% to 241 GWh. Electricity.trade reported that Week 22 results reflected how diversified flexibility can keep prices below regional premiums while still supplying neighbouring markets.
Week 22 demand and renewable generation trends
Greece’s weekly balance was supported by demand that did not decline. Consumption rose by 3.8%, adding 33 GWh compared with the previous week. Instead of tightening the market, the additional demand was met through improved supply conditions. Total variable renewable generation increased by 9.3% to 653 GWh, including wind up 14.1% and solar up 5.6%.
Hydropower output also strengthened during Week 22, rising by 12.1% to 97 GWh. Together, higher wind, solar and hydro generation contributed to domestic flexibility. That flexibility enabled Greece to expand exports while keeping prices below regional benchmarks. Prices remained well under Italy’s €123.58/MWh and Serbia’s €105.71/MWh.
Export role across Southeast European power flows
The export outcome is relevant because Greece is increasingly operating beyond a purely domestic market function. The system combines renewables, gas infrastructure, interconnections and trading optionality. In periods with favourable renewable output, Greece can supply neighbouring systems with surplus generation. During tighter conditions, its LNG and gas-fired fleet can provide dispatchable support, though at higher marginal cost.
Price spreads and cross-border trading implications
For traders, Greece’s Week 22 position created export optionality into higher-priced neighbouring markets. The weekly average spread to Italy was €36.81/MWh, with Italy clearing above Greece on that basis. Such differences align with where cross-border capacity allocation, forecasting and intraday positioning are used.
Overall, Week 22 reflected a system that could export flexibility while maintaining relatively low average pricing for the region. Greece recorded €86.77/MWh average prices alongside 241 GWh of net exports and 653 GWh of variable renewable generation. The combination placed Greece as a competitive balancing hub within the Southeast European power market.
