## Summary

Brian Janous, co-founder and chief commercial officer at Cloverleaf Infrastructure, explains the 'Watt-Bit Spread,' a concept describing the high value of electricity for AI versus its low current cost. He argues that this mispricing creates a bottleneck, as utilities lack the financial incentive to accelerate infrastructure build-outs needed for data centers. Janous, formerly Microsoft's VP of Energy, details how the industry's focus has shifted from securing real estate to securing power, creating new challenges for developers and utilities alike. He proposes 'advanced grid tariffs' to allow data center operators to pay a premium for faster capacity, thereby incentivizing utilities to invest in grid enhancements like storage and dynamic line rating.
