Verizon Cuts Energy Consumption at 24 U.S. Data Centers

Verizon has implemented an aggressive, intelligent energy-management systems from Vigilent to significantly cut energy consumption and carbon emissions at 24 of its U.S. data centers. Vigilent energy management systems consist of hundreds of wireless temperature sensors at each data center that are connected through an intelligent mesh network to on-site servers using energy management software. The company said this new system enabled it to:

  • Turn off approximately 40 percent of the computer room air conditioners in these data centers within two days of implementing the energy management systems, providing an instant reduction in energy consumption and an anticipated savings of more than 55 million kilowatts annually.

  • Reduce greenhouse gas emissions by more than 66 million pounds of CO2 on an annualized basis.

  • Decrease average temperatures by two degrees Fahrenheit throughout the data centers, with significantly reduced temperature fluctuations and extremes.

Verizon noted that its energy reduction and recycling initiatives in its facilities around the globe reduced CO2 emissions by more than 297.5 million pounds in 2010, leading to an improvement of more than 15 percent in the rate of emissions per terabyte of data.

"Vigilent energy management systems have reduced cooling consumption by more than 40 percent as well as provided important safeguards that help improve our uptime," said Mark Capurso, director of national technical operations at Verizon. "This combination of energy savings and improved efficiencies goes a long way toward helping meet Verizon's goal of improving its carbon efficiency by 15 percent this year.
