IBEX, Bulgaria’s electricity exchange, reported 2.915 TWh of day-ahead trading in October, 23.2% more than in October 2025. The baseload average price rose around 40% month on month to €232.03/MWh, as market liquidity remained substantially above year-earlier levels alongside a sharp increase in wholesale prices.
October day-ahead volume was around 6% below September and averaged about 94,024 MWh per day. The baseload average compared with €166.24/MWh in September, while the average peak price climbed approximately 71% to €217.66/MWh.
Intraday continuous-market volume reached 1.432 TWh, up around 21%, and its weighted average price rose 52.4% to €239.11/MWh. IBEX had 155 registered day-ahead participants, unchanged from September.
High prices continued in early November. IBEX traded at €303.78/MWh on 6 November, almost the same level as Hungary and marginally below prices in Serbia and Romania.
Rising year-on-year liquidity and high price volatility reinforce Bulgaria’s position as one of southeastern Europe’s principal trading hubs. The market conditions also increase the importance of hedging, intraday optimisation and flexible generation for suppliers and industrial consumers.
