AES Corporation

AES has a narrow and mixed moat. The U.S. utilities (AES Indiana and AES Ohio) enjoy efficient-scale local monopolies with regulatory constructs that support allowed returns and cost recovery over time.

The contracted-renewables platform benefits from long-term PPAs and development know-how, with a sizable backlog that provides multi-year revenue visibility, especially with hyperscale customers.

However, renewables development is highly competitive, capital intensive, and lacks strong pricing power; relationships and execution speed are advantages but not impregnable. International exposure adds currency and regulatory variability.

Overall we see a narrow moat based on a combination of regulated efficient scale and long-term contracts rather than unique technology or network effects.
