#24 | Ken Hersh: $20B in Energy, and Why Yellow Lights Stay Yellow

"Yellow lights don't turn green." Ken Hersh built a $20 billion energy firm on acting on the small warning instead of explaining it away.More on Ken Hersh and this episode: thedealtablepodcast.com/episodes/ken-hershHe co-founded NGP Energy Capital Management in 1988 and grew it past $20 billion under management across multiple funds, deploying more than $12 billion and generating a 30 percent annualized return over 27 years. From 2016 to 2025 he was president and chief executive of the George W. Bush Presidential Center.The method is the interesting part. He backs operators rather than assets, and he thinks probabilistically in a business where most exploration carries roughly a 30 percent chance of success, which makes a deterministic spreadsheet worse than useless. He screens hard for the documented biases that destroy returns: groupthink, escalation of commitment, recency bias.He also tells the Richard Rainwater story and explains what Rainwater's actual magic was, why first-day panic is a sign you are in the right job, how to read integrity in a management team, and what feeding the ducks means when liquidity appears and everyone else is waiting for a better price.Ken Hersh co-founded NGP Energy Capital Management and built it into a natural resources private equity firm with more than $20 billion under management.
