Episode notes
Uri And AI Demand Shaped ERCOT Priorities
- Keith highlighted Winter Storm Uri as a watershed event prompting winterization and focus on resource adequacy.
- He also pointed to the rapid rise of AI data centers as a concurrent, unprecedented demand challenge in Texas.
Price Signals Drive Rapid Storage Growth
- ERCOT's energy-only design creates very strong price signals that attract fast investment, especially in storage.
- High peaks (up to $5,000/MWh) plus streamlined interconnection accelerated >10 GW of batteries in a few years.
Send Forward-Looking Market Signals
- Forward-looking signals are necessary instead of only reacting when scarcity occurs.
- Design markets that incorporate expected load growth (e.g., AI data centers) to avoid ‘leaving when the house is on fire.’
