Philip Krein, a University of Illinois power systems professor, and J.J. Jaisouria, a Houston utilities consultant, dig into why electricity prices are rising near AI data centers. They debate whether data centers are scapegoats or real strain on an aging grid. They also explore self-powered facilities, spreading fixed costs, and why transmission buildout is the big hurdle.

Episode notes
Data Centers May Be Scapegoats For Grid Neglect
- J.J. Jaisouria argues data centers get blamed for power prices that also reflect 15 years of grid underinvestment.
- He says some centers secure long-term power deals, build on-site gas or nuclear generation, and can send excess power back while covering more utility fixed costs.
PG&E Says Data Centers Helped Cut Rates
- PG&E said data center growth helped cut its electricity rates by 13% since 2024.
- Darian Woods says the utility credited data centers with paying more fixed grid costs, lowering each customer's share.
Speed Of Data Center Demand Strains The Grid
- Philip Krein says the real problem is how fast data centers demand huge new loads, not just whether utilities underinvested before.
- He says centers can ask for 20% more capacity immediately, forcing transmission and substation costs into today's rates, especially in strained places like Northern Virginia.
