Title changed from Any BEV drivers interested in defecting from the grid? to Do we NEED TO dismantle the grid in the rural west?
Anyone living off-grid with a BEV?
It would seem to me that utilizing a BEV for both energy storage and energy transport would make a lot of sense.
I am one of the small minority (end-of-the-line high maintenance costs, and low kWh use) for whom the electric grid is already non-competitive in terms of the real cost, even though my current PG&E bill is effectively subsidized (E9, ~8 cents per kWh) so my bills do not reflect this reality.
I only pay ~$400 a year for the ~5,000 kWh to fuel both my LEAF and my home, which probably does not even cover what PG&E pays to maintain the final ~300 yards of lines to my home. The past and present CPUC policy of charging low-cost urban/suburban ratepayers more to subsidize lines to higher-cost locations with superior alternatives is unsustainable, IM0.
I could change the primary charge location of my BEV to balance my at-home (probably PV) energy production by season and time-of-day, greatly reducing my requirements for stationary batteries at home, by using my BEV as my powerline.
The article below gives some views on the economics of defecting from the grid, without even taking the BEV-as-powerline option into account.
The Power Grid Might Become The ‘Alternative’ — Off-Grid The Norm

For years, low-cost solar-plus-battery systems were seen as a distant possibility at best, a fringe technology not likely to be a threat to mainstream electricity delivery any time soon. By far, the limiting factor has been battery costs. But thanks to a confluence of factors playing out across the energy industry, the reality is that affordable battery storage is coming much sooner than most people realize. That approaching day of cheaper battery storage, when combined with solar PV, has the potential to fundamentally alter the electricity landscape.
While grid-tied solar has seen dramatic recent cost declines, until recently, solar-plus-battery systems have not been considered economically viable. However, concurrent declining costs of batteries, growing maturity of solar-plus-battery systems, and increasing adoption rates for these technologies are changing that. Recent media coverage, market analysis, and industry discussions—including the Edison Electric Institute’s January 2013 Disruptive Challenges—have gone so far as to suggest that low-cost solar-plus-battery systems could one day enable customers to cut the cord with their utility and go from grid connected to grid defected.
But while more and more people are discussing solar-plus-battery systems as a potential option at some point in the distant future, there has been a scarcity of detailed analysis to quantify when and where. Until now.
THE ECONOMICS OF GRID DEFECTION
Today, Rocky Mountain Institute, HOMER Energy, and CohnReznick Think Energy released The Economics of Grid Defection: When and where distributed solar generation plus storage competes with traditional utility service. Seeking to illustrate where grid parity will happen both first and last, the report considers five representative U.S. geographies (NY, KY, TX, CA, and HI). These geographies cover a range of solar resource potential, retail utility electricity prices, and solar PV penetration rates, considered across both commercial and residential regionally specific load profiles.
The report analyzes four possible scenarios: a more conservative base case plus more aggressive cases that consider technology improvements with accelerated cost declines, investments in energy efficiency coupled with load management, and the combination of technology-driven cost declines, energy efficiency, and load management. Even our base case results are compelling, but the combined improvements scenario is especially so, since efficiency and load management reduce the required size of the system while technology improvements reduce the cost of that system, compounding cost declines and greatly accelerating grid parity...
