New tariffs take effect on November 1
The national government has formalized fresh increases for electricity and gas bills that begin applying on Sunday, November 1, 2026. According to the Energy Secretariat, electricity in the Buenos Aires metropolitan area will rise by an average of 3.57%, while natural gas will go up 2.17% across the country. The changes were published on Friday, October 30 in the Official Gazette through resolutions issued by the National Gas and Electricity Regulatory Entity (ENReGE). Resolution 304/2026 confirmed the subsidy scheme, while Resolutions 841 to 876/2026, 886/2026 and 887/2026 carried the new tariff schedules.[S3][S2]
The electricity update covers only the Buenos Aires metropolitan area, since provincial regulators set power rates elsewhere in Argentina. The gas adjustment, by contrast, applies nationwide. The Energy Secretariat explained in a statement that electricity tariffs are revised monthly through a formula combining the Wholesale Domestic Price Index (IPIM) and the Consumer Price Index (IPC), both produced by the national statistics agency INDEC. For this round, the agency linked the November increase to the IPIM, which it tied to the effect of the war in the Middle East on costs.[S3][S2]
For Edenor customers, the company told BAE Negocios that the average bill increase will be 2.5%, with the final figure depending on the user category and consumption level. The distributor's own distribution cost component rises 3.18% compared with October. Edesur's distribution updates follow the same monthly review mechanism. The government estimated that the electricity increase will add roughly 1,700 pesos per month on average for AMBA users, though for three out of four households the rise will be closer to 1,150 pesos.[S2][S1]
How the electricity increase is calculated
ENReGE approved the new Edenor and Edesur schedules through Resolutions 886/2026 and 887/2026, both effective from November 1. The adjustments reflect updates to distribution costs, one of several components making up the final price of electricity. The calculation draws on two factors: the update set out in the five-year tariff review and the movement of price indices published by INDEC. For this adjustment, September figures were used, with the IPIM at 3.16% and the IPC at 1.93%.[S1][S2]
The percentage that ultimately appears on each bill will not necessarily match the distribution cost update, because the price of energy, taxes and applicable subsidies also play a part. For low-consumption residential users in category R1, the reference fixed charge reported for November is about 1,870.51 pesos per month at Edenor. A variable charge based on kilowatt-hours consumed is added to that amount, so the fixed charge does not represent the full bill. The final sum depends on recorded consumption, applicable discounts and taxes.[S1]
Households using more electricity face larger variable charges and, where relevant, must pay unsubsidized rates for energy consumed above the subsidized threshold. The scheme forms part of the tariff alignment process the government is maintaining for public services.[S1]
Subsidies maintained for SEF households
The government confirmed that homes covered by the Targeted Energy Subsidies (SEF) regime will keep a subsidized base consumption of 200 kWh per month during November. The decision changes, for that month, the 150 kWh reference limit originally planned for certain periods of the year. The Energy Secretariat also set an additional extraordinary 25% rebate for residential beneficiaries, on top of the general discount provided by the regime.[S1][S3]
The benefit applies to the energy component corresponding to recognized base consumption, not to the entire bill. Distribution charges, other tariff concepts and taxes may therefore still form part of the amount the user must pay. If a family uses more than 200 kWh in November, the excess is billed without the rebate attached to the subsidized block.[S1]
Gas increases and the Metrogas and Naturgy schedules
Natural gas tariffs also change from November 1, affecting distributors across the country including Metrogas and Naturgy, which serve different parts of the Buenos Aires metropolitan area. For Metrogas users, reported increases are about 2.95% in the City of Buenos Aires and 3.65% in parts of the Buenos Aires suburbs. Naturgy's reported adjustment is around 2.96%. Percentages can vary by consumption category and by the components included in each bill.[S1][S2]
Resolution 851/2026 approved the new values Metrogas will apply to consumption from November. Under the official schedules, unsubsidized residential users face monthly fixed charges before taxes, and those amounts cover only the fixed monthly charge rather than the full bill. A variable charge for cubic meters of gas consumed and the corresponding taxes are added to each amount. For residential categories R1, R2 and much of R3, the Metrogas schedule sets a charge of 328.26 pesos per cubic meter before taxes and without subsidies, while category R4 has different variable values depending on the zone.[S1]
On the subsidy side, the Energy Secretariat decided to maintain November rebates for households in the SEF regime. Resolution 304/2026 establishes a general 50% discount on the gas price component covered by the benefit, plus an extraordinary 24.25% rebate. Beneficiary households therefore receive a total rebate of 74.25% on the subsidized gas price component.[S1][S3]
