Tesla’s home battery is so popular it is sold out until 2016. That’s evidence of a strong demand for solutions among homeowners. The grid, however, may not be affected as much. If a house is only using the battery to store grid power for off-peak use or during outages, the grid doesn’t change much. If a house is using the battery to store home solar system energy and is self-sufficient, the house can be off the grid already. If a house is using the battery to store home solar system energy and sell the excess to the gird, then the grid still has to be there. There will be changes, but they won’t be revolutionary based on today’s technology. The Tesla battery may, however, be an example of an enabler that amplifies the benefits of future technologies. That milestone may be the greatest significance.

  2. “If a house is only using the battery to store grid power for off-peak use or during outages, the grid doesn’t change much.”

    Well the physical, built nature of the grid does not change much but what portions of the grid we use and do not use could change meaningfully. There is a large environmental gain to be made by peak-load shaving, mainly because when the grid is stressed to its limits the dirtiest power comes online. In places like New York City, that means the oldest, least efficient and dirtiest power plants. If enough peak load could be deferred outside of peak hours, then there would be “peaker” plants that never need to start up.

    If demand could regularly be reduced as part of a storage/smarter grid system, then reductions to the spinning reserve would also result–which could mean we have fewer plants running but not producing electrons as they wait for minute-to-minute demand.
