The Next BESS Race Is Not Only About Batteries: Why CORNEX Is Building a Latin America Energy Storage Ecosystem

China’s energy storage companies are accelerating their overseas expansion as global demand for battery energy storage systems (BESS) continues to rise.

At the South America Smart Energy Exhibition in São Paulo, Brazil, CORNEX (楚能新能源) signed strategic cooperation agreements with four Latin American partners — Yunda Energy Technology Group, Intermepro, ION Energy and JSN Energia — covering markets including Brazil, Argentina and wider Latin America.

The move highlights a broader industry shift:

Chinese battery companies are no longer competing only through product exports.

Instead, they are increasingly building:

• Local supply chains

• Regional service networks

• Manufacturing partnerships

• Long-term project cooperation

to capture the next stage of global BESS growth.

🔋 From Battery Supply to Localized Energy Storage Solutions

CORNEX’s partnerships cover multiple segments across the Latin American energy storage value chain.

With Intermepro in Argentina, CORNEX will cooperate on energy storage equipment sales, project delivery and operation & maintenance services, strengthening capabilities in:

• Local warehousing

• Logistics support

• Project commissioning

• After-sales services

The partnership aims to support expansion across Argentina, Brazil, Mexico, Central America and other South American markets.

Meanwhile, cooperation with ION Energy in Brazil will focus on expanding energy storage applications including:

• Commercial and industrial (C&I) storage

• Renewable energy integration

• Off-grid power solutions

These partnerships reflect growing demand in Latin America for flexible energy infrastructure as renewable deployment accelerates.

🇧🇷 Brazil Becomes a Strategic Gateway for BESS Localization

One of the key developments is CORNEX’s 1.5GWh battery cell framework agreement with Yunda Energy Technology Group.

The agreement supports Yunda’s overseas energy storage manufacturing base in Camaçari, Bahia, Brazil, helping develop a more localized battery storage supply chain in Latin America.

This represents an important trend in the global BESS market:

The future competition will not only depend on battery technology.

It will increasingly depend on:

🔋 Manufacturing localization🌎 Regional partnerships⚡ Project execution capability🤝 Long-term service infrastructure

🌎 Why Latin America Matters for Global BESS Growth

Latin America is entering a new phase of renewable energy development.

Countries across the region are expanding:

☀️ Solar power capacity🌬️ Wind generation🔋 Grid-scale energy storage

However, increasing renewable penetration is creating new requirements for:

• Grid flexibility

• Peak demand management

• Renewable integration

• Energy security

This creates significant opportunities for global BESS suppliers.

For companies like CORNEX, success in Latin America will depend not only on supplying batteries, but also on becoming part of the region’s emerging energy infrastructure ecosystem.
