A smart grid infrastructure can spot and stop energy “leaks,” optimize efficiency through better power factors and provide feedback loops that provide the right price signals to normalize energy loads during peak use. According to the Pacific Northwest Laboratory in partnership with the Department of Energy, the total potential benefit of implementing smart grid technologies over the next 20 years is conservatively estimated to have a present value of $75 billion. Vision SmartSynch creates extraordinary value for our customers by providing innovative Smart Grid Infrastructure solutions that leverage public wireless networks.
