  > Traditional electro-mechanical meters keep a running sum of power used, but can't tell the power company exactly how much power you were using at every minute of the day. Such a log, although still crude, gives the power company much more insight into your daily routine than they ever had before. Using traditional summing electro-mechanical meters assumes that electricity is priced uniformly at all times of day, and encourages over-consumption during times when spot market electricity is most expensive, the cost of which ends up being shifted to those who consume energy at lower spot market price times. Smart meters allow for time-of-use rates, which are a more economically (and in CO2 emissions) efficient way of pricing power. They do expose more information about the times of day that individual consumers use electricity to electric utilities, though. A consumer who is concerned about and also is proponent of market based pricing mechanisms could install battery storage to mask their usage profile, and even use it to do energy arbitrage.
