Local Energy Rate
From your last utility bill — used only to estimate cost, not energy use itself.

Peak Load is an illustrative estimate — not a code-compliant electrical demand-load calculation. Sizing a backup generator? See the Generator Sizing Calculator for a full load calculation.
This chart shows how your estimated annual energy use splits across HVAC, appliances, lighting & plug load, and always-on baseline load.
