Summary of Conference Call on Battery Energy Storage Systems (BESS) and WEG Industry Overview - **Industry**: Battery Energy Storage Systems (BESS) in Brazil - **Key Players**: Brookfield, WEG, ABB, Siemens (SIE), Schneider Electric (SU) Core Insights 1. **BESS Integration in Brazil**: Large-scale BESS is expected to be integrated into Brazil's energy grid due to issues with curtailment and reliance on renewable energy sources [1][5] 2. **Government Auction**: A BESS capacity auction of 2GW is scheduled for April, but results may vary due to pending regulations [1][5] 3. **Supplier Differentiation**: There is limited differentiation among Tier 1 BESS suppliers, with price being the primary decision factor [1][5] Financial Projections for WEG 1. **Revenue Potential**: BESS could contribute up to R$71 billion (~US$13 billion) to WEG's revenue by 2035, averaging R$6.4 billion (~US$1.2 billion) annually [2] 2. **Valuation Comparison**: WEG is trading at 21.4x EV/EBITDA for 2026 estimates, compared to peers ABB (16-20x) and Siemens (16.4x) [3] BESS Applications and Economics 1. **Application Segments**: BESS applications include large-scale for transmission and distribution, behind-the-meter, and mid-scale solutions [5] 2. **Curtailment Issues**: Selected Brookfield solar projects face curtailment rates of 40-50%, highlighting the need for BESS to enhance efficiency [5] 3. **Cost Trends**: Battery costs have decreased by 90% over the past decade, with current BESS prices ranging from R$1.1-1.3 million/MWh [5] 4. **Investment Returns**: Integrated projects (solar + BESS) can increase internal rates of return (IRRs) by 600-800 basis points [5] Regulatory and Market Challenges 1. **Auction Uncertainties**: The upcoming auction faces uncertainties regarding technical requirements and tax treatment, with a minimum of 1GW expected but a belief that 5GW is needed [5][6] 2. **Import Tariffs**: Recent increases in import tariffs on inverters and BESS components pose challenges for investment [6] Industry Requests 1. **Government Support**: The industry is requesting the government to align contract durations with battery life, update pricing models, and create tax incentives [7] 2. **Supply Chain Concentration**: The battery supply chain is heavily concentrated, with 85% of production in China, leading to higher costs for batteries produced in the US and EU [7] Technological Developments 1. **Sodium Batteries**: Sodium batteries are emerging as a cost-effective alternative, potentially capturing 20-30% of the market share in the next decade [7] 2. **Renewable Energy Integration**: The challenge for Brazil is to scale renewable energy without integrating wind, solar, and BESS effectively [7] Conclusion - The discussion emphasizes the potential growth of BESS in Brazil, particularly for WEG, while also highlighting regulatory challenges and the need for government support to facilitate market growth. The financial outlook for WEG remains positive, supported by the anticipated revenue contributions from BESS.
