California's power crisis deepened on several fronts Friday, with a utility losing a round in court, President Clinton calling for a high-level meeting and a consumer activist warning of a ratepayer rebellion when the latest bills go out. "The fuse has been lit. When people get their bills, it's going to detonate," Harvey Rosenfield, president of the Foundation for Consumers and Taxpayers Rights, said a day after state regulators approved electric rate increases of 7% to 15% by California's two biggest utilities.
