Wilmington's deregulated market, and Delaware's small-town municipal utilities
Delmarva Power delivered electricity at every sampled Wilmington address, and Wilmington sits in a deregulated retail market. You can shop for your own electricity supplier there while Delmarva keeps the wires running either way. Head south and the picture changes completely: Dover, Middletown and Smyrna each run their own small municipal electric utility, with no retail choice involved at all. Newark, home to the University of Delaware, is genuinely split territory in our sample.
So the account structure in Delaware depends heavily on which part of the state you're in. Wilmington's setup resembles the deregulated Mid-Atlantic pattern, while the smaller towns further south run more like traditional city-owned utilities. Wilmington is also the one city in our sample with confident water data, through the city's own water department.
