Bulgargaz, Bulgaria’s state-owned gas supplier, has proposed raising the regulated wholesale natural gas price for September 2026 to approximately EUR 41.30/MWh. The proposal implies a 4.77% increase compared with the level approved for the previous month. The filing indicates continued upward pressure on regulated gas supply costs.
The proposed September tariff is around 4.77% higher than the approximately EUR 39.40/MWh price approved for August. Bulgaria’s August tariff had already increased by 4.5% from July, extending a sequence of higher regulated wholesale gas prices in the market.
Regulatory review and timing for the September tariff
The proposed September price remains subject to review by the Commission for Energy and Water Regulation (KEVR). KEVR is expected to approve the final tariff on 1 September, following its assessment of the submitted pricing request. Before that decision date, Bulgargaz will update its proposal to reflect 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. Wholesale gas prices and other relevant supply costs could lead to a final tariff that differs from Bulgargaz’s initial proposal.
Potential impact as Bulgaria moves into the heating season
The latest request points to continued short-term pressure on Bulgaria’s wholesale gas market. Higher regulated supply costs could affect both consumers and businesses as Bulgaria enters the autumn heating season.
