Argentine Power Market Shows Modest Price Stabilization Despite Persistent Structural Vulnerabilities in Early 2026

The national grid operator CAMMESA projects spot market energy prices for 2026 ranging between 42 and 54.5 dollars per megawatt-hour, according to analysis by consultancy Aleph Energy authored by engineers Daniel Dreizzen and Nadia Sager. These levels represent a slight downward adjustment from 2025 averages yet remain competitive against current term market valuations. When incorporating capacity charges, ancillary services and transmission costs, the total monomial expense for large users averages approximately 67 dollars per megawatt-hour annually, below 2025 figures. The system maintains a structural cost floor near 20 dollars per megawatt-hour persisting across all price scenarios, reflecting generation infrastructure operating near reliability limits.

Seasonal volatility remains a principal risk factor. Winter months concentrate peak pricing and system stress, undermining the spot market’s capacity to provide long-term investment signals. Elevated revenues concentrate in few annual months while facing regulatory and dispatch uncertainties, making new thermal generation investments economically unjustifiable under marginal pricing logic alone. The term market’s appeal derives not from average pricing but from volatility reduction and critical month cost mitigation.

The electricity sector confronts simultaneous regulatory paralysis despite government commitments to market restructuring. Hydroelectric plant concession tenders initially scheduled for early April experienced multiple delays without confirmed restart dates, with administrative tasks outlined in Joint Resolution 2/2025 repeating previously completed steps. Battery energy storage system procurements for the Buenos Aires metropolitan area face similar postponements. The winter seasonal programming approved by the Energy Secretariat set electricity prices at 57 dollars per megawatt-hour for May through October 2025, substantially below CAMMESA’s estimated 89 dollar per megawatt-hour actual cost including fuel imports. This gap ensures even unsubsidized consumer segments including high-income residentials and large industrial users pay only 64 percent of real supply costs.

The government implemented November 2025 market deregulation measures aligned with IMF commitments through Resolution 400/2025, introducing marginal pricing and term markets for energy and capacity contracts. Energy Coordination Secretary Daniel González projects subsidy reductions from 0.6 percent to 0.5 percent of GDP in 2026, with residential users collectively covering 67 percent of wholesale costs versus 53 percent previously. Industrial consumers anticipate cost increases between 8 and 10 dollars per megawatt-hour during the transition. A 1.1 billion dollar transmission infrastructure tender targeting the Buenos Aires region awaits launch with private financing recovered through beneficiary tariffs.
