A rough comparison of a KASCMF geothermal central plant against a conventional chiller-plus-boiler plant. Our two commissioned projects measured 44–50% savings and 5.8–6.5-year payback; your numbers depend on tariff and hours.
Enter a realistic annual conventional energy cost to estimate savings.

Rough estimate using your inputs and a measured 44–50% saving band from Koven-commissioned central-plant projects. Independent US life-cycle studies (NYSERDA, LBL) also find geothermal lowest on 30-year life-cycle cost. Actual payback depends on your tariff, run hours, and available tax credits/incentives.
