Verizon Taps Eltek for Off-Grid Hybrid Solar Installation
The energy company installed a Flatpack2 HE hybrid solar-propane DC power system at Verizon’s Bear Mountain, Calif., wireless base station. It replaces a 20-year-old hybrid solar power system. The cell site is located in a remote northern California area near Mt. Shasta and serves both local residents and a large population of wilderness tourists.
The Flatpack2 HE hybrid solar power system includes a Flatpack2 HE solar converter, Flatpack2 HE rectifier and Smartpack controller. The Flatpack2 HE solar converter connects to the solar panels and converts the solar power into a regulated 48V DC supply for the telecom equipment.
Besides installing the solar system, Eltek is also managing the entire power infrastructure including inverters, rectifiers, generators and battery recharging. The new system has cut the generators’ required run time from 18 hours to less than four hours per day and has dramatically reduced maintenance costs for Verizon, Eltek says.
In June, Clearwater Systems announced that a Verizon data center using its Dolphin WaterCare technology has cut water discharges by more than 20 percent, or 1.6 million gallons, compared to chemically treated water.
Dolphin WaterCare was installed in the center’s cooling system to treat a maximum cooling load of about 2,600 tons, and provides the Twinsburg site with an opportunity for water reuse. By using the discharge water from the cooling tower, Verizon can implement graywater applications such as landscape irrigation. The project helped Verizon win a 2012 Green Enterprise IT Award from the Uptime Institute.
In March the communications company announced that it was aiming to cut its CO2 intensity in half by 2020, using 2009 as a baseline. The company made the announcement as it released its first combined financial and corporate responsibility report, which revealed that Verizon reduced its carbon intensity by 30 percent from 2009 to 2011. This means the company needs another 20 percentage point decrease to reach its 2020 goal.
Verizon’s carbon efficiency metric, unveiled in 2011, divides the company’s carbon emissions in metric tons by the amount of data that it transports, in terabytes. The carbon emissions used in the metric include electricity, building fuels and vehicle fuels.
