On February 8, 2011, George Jepsen, attorney general for the State of Connecticut submitted a brief requesting the Department of Public Utility Control reject CL&P’s AMI deployment plan, citing the $500 million dollar ratepayer-funded plan would yield few benefits. Since CL&P customers already benefit from AMR meters, the AG does not believe the price tag is worth the near term deployment of AMI meters. In the event AMI deployment is approved, the AG requests the following limitations:

  • Surgical deployment – provided only when requested by customers who are willing to pay for them
  • Replacement deployment – as AMR meters die, replace them with AMI meters
  • Prudence review – cost recovery via a base rate case and only after CL&P demonstrates the costs were prudent

It is unfortunate the AG does not see that a couple of the limits he is seeking to place on the program would erode and further minimize the benefits of AMI deployment. Operational savings are optimized when there is full deployment. CL&P submitted a cost-benefit analysis. Here are just some of the benefits:

  • Peak load reduction of 125 megawatts annually. This is sizable enough to forgo running a small power plant. Numerous additional benefits stem from this fact alone. When you forgo a power plant, you eliminate all the expense, environmental impact, energy , etc. that goes along with running the plant
  • Total energy reduction of 190 million kWh per year, saving enough energy to power 20,000 homes
  • Carbon emission reduction of 100,000 per year, giving Connecticut air the positive equivalent of 13,000 less cars on the road
  • Two percent reduction in storm outage duration

These benefits will be further optimized with full deployment, as that sets the stage for the best customer education and engagement process.
