What Delaware's numbers say about electrical

Delaware is one of the fastest-growing Columbus-metro suburbs tracked here: 46,636 people (2025 estimate), up 12.9% since 2020[2]. On the map that's 20.4 square miles holding 2,285 residents per square mile, the 12th densest of the suburbs here; it sits entirely in Delaware County, with ZIP code 43015[3].

New construction arrives with 200-amp panels and room to grow; the older homes nearby are the ones where panels fill up, double-taps appear, and an EV charger triggers a load calculation.

43015 is the city's single ZIP code[5].

The closest tracked neighbours are Powell (8.2 mi S), Dublin (12.5 mi S) and Worthington (13.4 mi S)[3].

14% of Delaware's housing was built in 1960–1979[1] — the 6th-lowest share of the 15 Columbus-area suburbs we cover; nearby, Powell (1%), Dublin (7%), and Worthington (45%). That window includes roughly 1965–1973, when some homes got aluminum branch wiring[6].

20% of Delaware homes heat with electricity and 78% with gas[1] — the 5th-lowest share of the 15 Columbus-area suburbs we cover (Powell (19%), Dublin (21%), and Worthington (18%) nearby). Gas-heated homes often have more panel headroom, but only a load calculation tells.

Within 10 miles of central Delaware: 59 damaging-wind reports and 0 lightning-damage reports in 2016–2025, the latest on Aug 12, 2025[4].

Ice is the other outage risk: 55 winter-storm, ice or hard-freeze days in 2016–2025[4] — worth knowing when sizing a generator or asking about whole-home surge protection.

6% of Delaware's housing is from 2020 or later[1] — new enough that builder warranties still apply to many electrical defects.

Measured against the 15 suburbs on this site, Delaware records the fewest lightning-damage reports nearby (0, tied with 5 other suburbs)[4].
