A recent assessment by energy regulator RAAEY indicates that Greece’s electricity retail market remained largely stable between May and October, with only modest shifts in supplier positions across customer categories and voltage levels.
PPC slightly increased its dominance, reaching just over 72% of nationwide customers by October. This represents a small gain compared to late spring, confirming the utility’s continued strength in household and small business supply.
Examining network segments, PPC’s low-voltage presence dipped marginally, while its medium-voltage share weakened more noticeably over the five-month period. Consumption-based data also point to a gradual erosion of PPC’s share outside the low-voltage segment, particularly among medium- and high-voltage users, where competition is strongest.
Protergia consolidated its position as PPC’s main challenger, capturing a significant portion of demand in the low- and medium-voltage markets. In the high-voltage segment, Protergia emerged as the clear leader by electricity consumption, widening the gap over competitors.
Overall, the data highlight a market characterized by continuity rather than disruption, with PPC retaining a commanding lead in customer numbers, while rival suppliers continue strengthening their foothold among energy-intensive users.
