Navigating the Winter Peak
With hydroelectric generation historicals showing strong volatility, preparing the SADI grid for the impending winter months requires a multi-faceted approach. The Comahue dams continue to be the primary variable.

Key Takeaways
- 1.
Reservoir levels are currently 12% below the 10-year historical average heading into winter.
- 2.
Contingency thermal spinning reserves have been increased by 400MW to prevent load shedding.
- 3.
Industrial demand response (DR) contracts could mitigate the remaining deficit.
Thermal Backfill Operations
To combat the potential shortfall in baseload hydro power, CAMMESA is pre-positioning thermal assets across the central node.
While expensive, operating combined-cycle natural gas lines out of standard merit order will prevent catastrophic frequency drops if a sudden cold snap creates simultaneous heating demands in Buenos Aires.
System analysis required for detailed metrics.
The grid simulation model shows stable frequency preservation assuming natural gas delivery pressures can be maintained during the peak residential heating windows.
