I appreciate your concern, but the same issue would apply with existing expert systems or linear regression models that wouldn't typically be classified as "AI" today. Most power companies are subject to fairly strict regulations so they generally can't cut off customers unless bills are badly overdue, or the customer tampers with utility equipment. In some jurisdictions the power companies are required to report suspicious usage patterns to law enforcement; that may be objectionable on privacy grounds but that's a political issue, not really an AI issue. Where there's a large power imbalance between private citizens and large institutions we should address that with laws and regulations based on impact, fairness, and accountability rather than trying to specify how those institutions can use particular algorithms.
