- Before installing any smart meters, CenterPoint Energy and vendors launched a proprietary wireless radio frequency (RF) communications network. In turn, the utility has successful read rates of 99.91 % on daily register reads and 99.65 % on 15-minute interval reads which testify to the reliability of the network.
- Further, two-way digital communication has allowed for five million remote electric service connections and disconnections, saving consumers $24 million in eliminated fees, reducing the company’s vehicle fuel consumption by about 500,000 gallons, and avoiding 4,500 metric tons of carbon emissions.
- The installation of 394 intelligent grid switching devices (IGSDs) and automation of 21 substations through 2012 has created a 21% improvement in outage response, with 70% of affected customers gaining back electricity in minutes rather than a half hour or more. By the end of the 2013, CenterPoint would have installed 600 IGSDs in Houston and automation equipment at 31 substations.
