Project Summary:

Connecticut Light and Power (CL&P), a subsidiary of Northeast Utilities is based in Berlin, CT. The company was successful in its pilot project which aimed at installing 3,000 smart meters including both commercial and residential customers [1, 2, 3] from June 1, 2009 through August 31, 2009 [4]. The Pilot project is also known as the "Plan-it Wise Energy Program". The objective of the program was achieved as it gained an insight into customer interest in, and response to, three peak time dynamic pricing rates.

Technologies tested in the pilot program include:
♦ Smart thermostat
♦ A/C switch
♦ Energy orb
♦ In-home display (IHD)

CL&P targeted to deploy about 1.2 million electric smart meters in Connecticut [3, 5]. CL&P estimated a $500 million in total cost for the smart grid project in Connecticut which would save $600 million in energy for the consumers [2, 6]. With this program [7], CL&P estimated that peak demand for power would be reduced by approximately 125 megawatts annually. It was also estimated that customers would reduce their total energy usage annually by about 190 million kilowatt hours and Connecticut would also see a reduction in carbon emissions of approximately 100,000 tons per year.
CL&P subsequently proposed deploying AMI system-wide starting in December 2012 with a four-year implementation. The project would progress through information technology development for dynamic pricing and on-bill hourly energy usage analytics, with dynamic pricing available to all customers by 2016. Technology for increasing efficiencies in outage detection, theft detection, and remote service activation had been expected to be developed through 2017 [8].
