The cooling adaptation quote

A public cost becomes comparable only with secured MW, preserved MWh and the adaptation lifetime.

The cooling adaptation quote

Add the missing denominator to public cost figures: secured MW, preserved MWh, lifetime, construction outage, auxiliary power and separate water balances.

This is a financial teaching model. It calculates no safety, ecology, permitting, hydrology or grid flows. Withdrawal and consumption remain separate.

Method, formulas and sources

CAPEX and the one-off outage cost are annualised with a capital recovery factor. OPEX and auxiliary energy are added. The total is divided by annual derating avoided. Cost per kW uses CAPEX and secured capacity only.

  • Annual cost = annuity(CAPEX + outage cost) + OPEX + auxiliary cost
  • Cost/MWh = annual cost ÷ annual derating avoided
  • Cost/kW = CAPEX ÷ secured capacity
  • Withdrawal and consumption are compared separately, without automatic conversion
