New Standards: Navigating Challenges and Seizing Opportunities

To maintain the leadership of top brands in the energy storage industry, BNEF has further optimized its Tier 1 evaluation metrics for 2025, with a greater emphasis on global delivery capabilities, large-scale applications, and stricter audits of customer diversity and project validity. Projects that meet these new standards are considered highly financeable, further strengthening the competitive advantage of Tier 1 companies.

As a leading authority in the global renewable energy sector, BNEF is renowned for its thorough review process, detailed qualification checks, and expert evaluation teams. The results of its Tier 1 list are impartial and trustworthy, making it one of the most respected and influential rankings in the energy storage industry. BNEF’s Tier 1 list is widely acknowledged by international financial institutions and renewable energy investors.
