zapkitty, how reasonable are your figures for the cost of FF electricity? In the other thread you posit .2 cents/kwh — do you have a source for that number?

That’s from LPP. They have a breakdown of estimated FF costs in the Google talk and Lerner-hakase has used .02 kwh several times.

More recently, Lerner has quoted about 3¢, but it’s all tied up with mass mfr’g extrapolation, siting, etc. But that’s the ballpark. Really, the capital costs get retired very fast, and then the ongoing maintenance is composed of electrode replacement and staffing costs. These might amount to ~$60K/unit/year, for about 40 million kwh. Which works out to ~0.15¢/kwh.
Add whatever capital cost retirement fraction you consider reasonable.
