Generator Installation in Wilmington, DE
Wilmington Delaware sits on Delmarva Power, which means coastal storm and ice-event outages drive the standby market. DuPont and Chemours executives in Trolley Square and Greenville want full-home coverage; mid-tier homeowners pick interlock-plus-portable. Trolley Square's century-old service entrances usually need a panel rebuild before any ATS goes in.
Wilmington generator installs run $5,500-$14,000 for 22-26 kW Generac, Kohler, or Cummins units. DE requires a state EC license. Permits ($75-$200). Setbacks: 5 ft from structures, 18 inches from PL.
