- Load reality: 100 EVs charging simultaneously = ~1 MW demand; typical US residential neighborhood peak = 0.5 MW — immediate transformer problem - 70 million US distribution transformers; DOE estimates 30% need replacement or upgrade for EV loads — $50B+ infrastructure requirement - V2G potential: 50 million EVs × 60 kWh average = 3 TWh bidirectional storage — more than all US utility-scale battery storage installed as of 2025 - Smart charging (V1G) is the lowest-cost first step: time-of-use pricing shifts charging to off-peak hours, avoiding 80% of grid upgrade cost
