Generator TCO Calculator
Total cost of ownership over 5–15 years: equipment estimate corridor, fuel at your local prices, and typical maintenance — natural gas vs diesel.
Testing plus outages — 60 h/yr is a common planning baseline.
Editable defaults — use the price from your utility bill or fuel contract for a sharper estimate.
