When we bought our Volt we had not properly studied the opportunities and subsidies for hardware and energy, and our dealer was ignorant of every number that didn't have a dollar sign in front of it. Yesterday I talked with another dealer and discovered no improvement in dealer knowledge, so (1) provided this information to that dealer's sales manager and (2) decided to post it here. It's all about money and energy...
Our experience is specific to San Diego, but the principles apply to varying degrees in many other areas of the country.
Our 240V BLINK charger was subsidized, to our immense satisfaction. The $1,335 bill was offset by that subsidy and our total out of pocket was $135. Our point of contact for the contractor that did the work and the subsidy was SPX. (The clueless dealer had mentioned a "240 amp cable at Lowes...")
Pre-Volt, our household energy was billed on a tier basis, and the highest tier was 33c per kWh. Our average bill was $175 per month. Once we showed our local power company that we had a plug-in hybrid, we were permitted to select Time-Of-Use billing - which affected the overall house usage rates. The new cap was 25c per kWh for the entire house, with no tiers for energy use but different rates depending on when the energy is used. Peak, for example, is noon to 6 - that's at the 25c max rate. Super off-peak is midnight to 5AM, which is of course when the Volt charges - and the rate during that period is 14c.
OUR COST OF OPERATION
Thanks to the new billing rate (and a new refrigerator), our overall household bill - INCLUDING THE VOLT - has dropped from a 2011 average of $175 to $136. At 14c per kWh and a typical nightly charge of 13kWh, that's $1.82. I finally learned how to get 44 miles per charge (and it's improving), so that would be 4.1c per mile. However, considering the new 25c/kWh peak rate vs the former 33c, we really drive... (wait for it... drum roll...) ... FREE.
