## Summary

Brian Janous, co-founder and chief commercial officer at Cloverleaf Infrastructure, explains the 'Watt-Bit Spread,' a heuristic describing the high value of electricity for AI data centers relative to its current low market price. He argues that this mispricing fails to incentivize utilities to build new generation and transmission infrastructure fast enough to meet surging demand. Janous contrasts the 'theory of constraints' mindset of cloud providers with the slow, regulated utility model, proposing 'advanced grid tariffs' to align incentives. He notes that while land is cheap, securing power-ready sites now requires multi-billion dollar commitments, creating significant hesitation among developers who lack demand certainty.
