    I don't see PHEVs causing the need for a massive infrastructure investment -- most battery charging should take place at night, which is off-peak for electric utilities.

      Actually, our grid needs a massive upgrade for higher reliability and redundancy anyway.

      But PHEVs are potentially a supply as well as a demand, and therefore would create an immediate need for a robust, redundant, dynamic transmission system architecture that can handle distributed power generation, rather than the centralized hub and spoke model that underlies today's infrastructure.

      Your car becomes a 180 hp backup generator, (plus battery UC storage system) providing an uninterrupted power supply for your house if the grid goes down, or, depending on the cost of the fuel, it could send power back to the grid.

        ----------------------
        While suitably configured PHEVs could be used as emergency backup generators, I'm not sure anyone is planning for them to provide grid power. Fuel cell autos could possibly perform this role, but IMO, PHEVs' noxious exhaust gasses will prevent using them for distributed power generation, won't they?
