Natural gas resources (including both national production and fiscal royalties) reached 1000 ktep at the end of June 2025, marking a 9% decline compared to the same period of the previous year, according to the Energy Situation Report for June 2025, published by the National Observatory of Energy and Mines.
Dry commercial gas production fell by 5%, while royalties from the transit of Algerian gas recorded a 14% decline at the end of June 2025 compared to June 2024, standing at 424 ktep.
It should be noted that the Hasdrubal field and the Nawara field posted respective decreases of 11% and 31%. Similarly, the Miskar field saw its production fall by 2%.
As for commercial gas from the South, its production rose by 9% at the end of June 2025 compared to the same period last year.
Transmed royalties down 14%
The Observatory highlighted the 14% decline in fiscal royalties from the transit of Algerian gas as of June 2025 compared with June 2024.
Furthermore, the distribution of total royalties between those allocated to STEG (the Tunisian Electricity and Gas Company) and those exported shows that the largest share was ceded to STEG (100% in June 2025).
It is worth noting that STEG exceeded its withdrawals from royalties due to the Tunisian state in June 2025 by 76 million m³, which is currently under settlement.
Regarding purchases of Algerian gas, these recorded a 23% increase between June 2024 and June 2025, reaching 1290 ktep.
National natural gas supply posted a 10% increase between June 2024 and June 2025, amounting to 2302 ktep.
Natural gas demand rises 10%
Total natural gas demand rose by 10% between June 2024 and June 2025, reaching 2293 ktep-pci. Demand for power generation increased by 13%, while final consumption also rose by 4%.
The power generation sector remains by far the largest consumer of natural gas (69% of total demand at end-June 2025), with electricity generation relying on natural gas for around 94% of output.
The decline in electricity sector demand is due to limited natural gas availability and does not reflect the actual demand of the sector.
For final uses (outside power generation), natural gas demand rose by 4%, reaching 715 ktep-pci. Demand from medium and low-pressure clients increased by 4%, while high-pressure clients saw a 5% increase.
Overall specific consumption of power generation facilities increased by 11% between June 2024 and June 2025, reaching 209 toe/GWh.
