Brazil’s battery energy storage auctions are drawing attention to project development and opportunities for investment, acquisition and partnerships. In this context, the ePowerBay Project Hub connects project owners with investors, buyers and suppliers.

With BESS projects already published, the Hub allows users to explore technical specifications and identify opportunities for further assessment.

Discover the Project Hub

Project owners can register their developments and indicate an interest in selling, attracting investment or establishing partnerships. Registration starts with the EPE/AEGE Project Data Sheet in PDF format. The platform assists with data extraction, and the person responsible reviews the information before submission.

Publication protects commercially sensitive information: projects are presented under code names, and access to company identities and additional information depends on applicable permissions and the owner’s authorization. Companies with full access can request contact, and the owner decides whether to approve each request.
