    We have this in CA. I have Tesla batteries and they promote wanting me to enroll my batteries into a larger grid so their capacity can be used during higher load events.

    I thought it was a novel idea when I heard about it.

            Its an inefficient use of capital.

              Whose capital?

                The people buying the batteries and the government&#x27;s capital. It only benefits the private util companies.

                The better option is for the government&#x2F;utility company to build out the required storage for a fraction of the cost.

                  The former should be allowed to make their own decisions. I agree that the latter should probably be kept out of this: government is usually not very good at making these decisions. But alas, in many places they play a huge role in the electricity supply and distribution.

                    Yes, but that&#x27;s how we arrive to local economical maxima that are much, much closer to the global minimum that to the global maximum. The personal decisions aggregate, after all.
