In February 2025, the Ministry of Energy launched a tender for electrical energy storage with the goal of achieving a 500 MW installation by 2028.
Known as AlmaGBA (Energy Storage for Greater Buenos Aires), during the application period, a bid of 1,347 MW was received, exceeding the initial offer by approximately 170%.
What are the main characteristics of AlmaGBA?
🔋 Capacity tendered: 500 MW with 4 hours of storage.
🗓️ Maximum commissioning date: December 31, 2028.
💵 Estimated investment: US$500 million.
27 projects totaling 1,347 MW were submitted (significantly exceeding the 500 MW target). Official awards are expected in August 2025.
Current Storage in Argentina
Argentina currently has a BESS electrical storage capacity of 10 MWh for grid use. This capacity is distributed across two different plants:
- San Nicolás (AES Argentina)
- San Juan (360Energy)
👷Strategic Importance:
The AlmaGBA tender marks a milestone in Argentina's energy transition. Its objective is to reduce power outages, support renewable energy, and improve the flexibility of the electrical system.
🎯Looking to the Future:
Policymakers in Latin America see electrical storage as a key solution for attracting greater clean, reliable, and efficient energy capacity, and Argentina is no exception.
