American utility executives expect as many as one-fifth to half of customers to choose a new power supplier as the electricity market deregulates. That implies a significant number of customers may be buying green power. The executives also say they do not see much in the way of savings -- because of restructuring -- for residential customers. The 1998 Electric Industry Outlook, a survey of leaders of US utilities, also indicates that they foresee much more consolidation as well as fewer nuclear power stations. The survey is by the Washington International Energy Group, consultants based in Washington DC.
