One utility already moving in this direction is Connecticut Light & Power (CL&P). The company is using wireless smart grid technology as part of a pilot program, among the largest customer-focused pilots of its kind in North America to date. This summer, 3,000 CL&P customers are taking part in the utility’s Plan-It Wise Energy program, a voluntary rate program to test residential, commercial, and industrial customers’ interest in, and response to, time-based energy rates and smart meters. Smart meters will measure customers’ electricity usage in one-hour intervals. The system will collect and transmit information about customer electricity usage to the utility, and then back to the customer, via a two-way wireless network.
