I'm on the regular tiering service with SCE, and I usually fall on Tier 3. I just got the FFET a few days ago so it will probably take me to tier 4. But assuming I stay on tier 3, I pay around 19 cents for kWh. Now bear with me on the math. Reading other posts I see that it takes around 7.2kWh to fully charge the battery. so 19 cents times 7.2kwh is $1.37. So it costs me $1.37 to fully charge the battery, which is good for 20 miles of electric drive. My local Mobile gas station is charging $2.39 per gallon. Assuming 40 mpg oh hybrid mode, half a gallon would last me those same 20 miles and would cost me $1.19. 18 cents cheaper. So am I looking at this right? Is it cheaper to just go on hybrid mode?
