Short Summary

This study comprehensively analyzes the interannual complementarity of wind, solar, and hydroelectric resources in Argentina over 38 years, assessing the impact of low-frequency ocean-atmosphere variations. It finds limited complementarity with the current spatial distribution of renewable capacity, emphasizing the significant control of climatic drivers and the need for alternative spatial schemes for future energy development.

Objective

• To conduct a comprehensive analysis of the interannual complementarity of wind, solar, and hydroelectric resources over Argentina.
• To assess the impact of low-frequency ocean-atmosphere variations on these renewable energy resources.

Study Configuration

• Spatial Scale: Argentina
• Temporal Scale: Interannual scale, spanning 38 years.

Methodology and Data

• Models used: Not explicitly mentioned for direct use in the study; reanalysis data implies underlying models used for its generation.
• Data sources: Reanalysis-based data, streamflow measurements.

Main Results

• Little potential for complementarity was found between solar, wind, and hydro resources for the current spatial distribution of renewable capacity in Argentina.
• Climatic drivers exert significant control over wind, solar, and hydro resources.
• The Antarctic Oscillation (AAO) index shows anticorrelations with wind speeds.
• Streamflows over northern Patagonia exhibit negative relationships with the AAO and a positive relationship with the El Niño/Southern Oscillation.
• Streamflows over southern Patagonia show positive relationships with Southern Blob (SB) and AAO indices, driven by variations in temperature and precipitation.
• The solar resource demonstrates strong links with all ocean-rooted climate indices during winter.
• These results provide insight into the potential predictability of renewable energy resources on the interannual scale.

Contributions

• Provides a comprehensive interannual analysis of wind, solar, and hydroelectric resource complementarity in Argentina.
• Quantifies the impact of low-frequency ocean-atmosphere variations (e.g., AAO, ENSO, Southern Blob) on these renewable resources.
• Highlights the necessity for studying different spatial schemes for future renewable capacity additions to cope with intermittency.
• Offers insights into the potential predictability of renewable energy resources on an interannual scale, linking them to climatic drivers.
