My take on it is that it's being used to subsidize SolarCity. If the charging stations really are break-even in operating costs, then it could be a viable plan. At the least, I'd guess the stations are much cheaper than traditional gas stations, so proliferation may not be as expensive as it seems.

Then again, I'm not a business expert, so perhaps there's bookkeeping shenanigans here as well.
