What Centennial's numbers say about electrical

Centennial is one of the most established suburbs tracked here — 108,658 people (2025 estimate), up just 0.6% since 2020^[2]. The city spans 30.2 square miles at 3,603 residents per square mile (the 7th densest) and sits entirely in Arapahoe County, served by ZIP codes 80112, 80122, 80016, 80015, 80121^[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.

Centennial is split across 5 ZIP codes: 80112 (27% of the city's land), 80122 (22% of the city's land), 80016 (18% of the city's land), 80015 (14% of the city's land), 80121 (11% of the city's land)^[5].

Nearest of the other suburbs we track: Parker (7.5 mi SE), Englewood (8.0 mi NW) and Littleton (8.3 mi W)^[3].

40% of Centennial's housing was built in 1960–1979^[1] — the 4th-highest share of the 15 Denver-area suburbs we cover; nearby, Parker (2%), Englewood (23%), and Littleton (26%). That window includes roughly 1965–1973, when some homes got aluminum branch wiring^[6].

21% of Centennial homes heat with electricity and 77% with gas^[1] — the 2nd-lowest share of the 15 Denver-area suburbs we cover (Parker (24%), Englewood (34%), and Littleton (29%) nearby). Gas-heated homes often have more panel headroom, but only a load calculation tells.

Within 10 miles of central Centennial: 45 damaging-wind reports and 3 lightning-damage reports in 2016–2025, the latest on Jul 22, 2025^[4].

2% of Centennial's housing is from 2020 or later^[1] — new enough that builder warranties still apply to many electrical defects.
