The Connecticut Light & Power Company (CL&P) was formed on Aug. 9, 1917 when the Rocky River Power Co., Housatonic Power Co., United Electric Light & Water Co., and Seymour Electric Co. merged together, creating a utility serving Waterbury, New Britain, Norwalk, Greenwich, and Seymour. Those five cities are CL&P's original service territory.

Much of CL&P's growth can be attributed to its acquisition of varius Connecticut utilities over the years. The list of utilities that merged into CL&P could nearly run from here to the moon and back, but some of the big ones I'll cover are the Hartford Electric Light Co., Litchfield Electric Light & Power Co., Danbury & Bethel Gas & Electric Light Co., Connecticut Power Co., and Manchester Electric Co.
