CFE Electric 2015 summer rates

I noticed this year that they increased the 2nd rate tier from 1500kw to 1800kw.
My last bill still showed RP being at the 1E rate, I thought that was going to change to 1F?

Can anyone tell me if the 600-1800 tier is still affordable.
Next year will be in RP a lot during June/July.

The 0-600 tier is approx. .045 cents per kw. still the same as last year.
Thanks,
