Overview
- The Secretaría de Energía published Resolución 167/2026 on July 24, 2026, directing that Diferencias Diarias Acumuladas (DDA) be calculated and added to tariffs every two months instead of on a seasonal basis.
- DDA is the accounting tool that reconciles the price of gas estimated when tariffs are set with the price distributors actually pay, and the change shortens the accumulation period from roughly six months to two months.
- Officials say the goal is to avoid a 'double seasonal effect' when higher winter consumption coincides with higher wholesale costs and to give users more gradual, predictable adjustments; the change does not automatically lower bills.
- ENARGAS must adapt its procedures and make the first DDA determination under the bimonthly rule with the tariff schedules for August 2026, and the measure stays in force under the national energy emergency through December 31, 2027.
- The shift comes as distributors take on more direct responsibility for gas purchases and as Argentina still faces volatile LNG import costs and dollar-linked price swings that will determine how large future bimonthly corrections are.
