If you export TED's 1 hour data, then you can either manually scan for the minimum KW, or write a program to extract the minimum or plot the data, and because this power is averaged over a 1 hour time span it also equals the minimum KWH.
Assuming your rate is constant, then the rate times KWH minimum provides the minimum hourly cost. At night mine might be less than $ 0.13/hour. The nighttime maximum might be about $ 0.26/hour.
If you have a variable rate, then it may be necessary to determine the minimum KWH in different time regions, and determine which is minimum cost. Why do you care about minimum cost per hour? Why not think in KWH?
