Bulgaria’s state-owned gas supplier Bulgargaz has proposed increasing the regulated wholesale natural gas price for September 2026 to approximately EUR 41.30/MWh, signalling continued upward pressure on gas supply costs.
The proposed tariff is around 4.77% higher than the approximately EUR 39.40/MWh price approved for August. The August tariff had already risen by 4.5% from July, extending a recent trend of increasing regulated wholesale gas prices in Bulgaria.
The proposed September price remains subject to review by the Commission for Energy and Water Regulation (KEVR). The regulator is expected to approve the final tariff on 1 September, while Bulgargaz will update its proposal beforehand to reflect the latest developments in international gas markets.
KEVR is also expected to hold a public discussion toward the end of August as part of the price-setting procedure. Market conditions, including wholesale gas prices and other relevant supply costs, could therefore lead to a final tariff that differs from Bulgargaz’s initial proposal.
The latest request nevertheless points to continued short-term pressure on Bulgaria’s wholesale gas market, with higher regulated supply costs potentially affecting both consumers and businesses as the country enters the autumn heating season.
