CenturyLink Works with ComEd to Lower Chicago Data Center PUE

August 11, 2014 By Linda Hardesty

CenturyLink energy manageComEd is working with CenturyLink Technology Solutions on a multi-year energy efficiency project that will help the telecommunications company reduce the energy use of its Chicago CH2 data center by 7.4 million kWh annually.

The project is part of ComEd’s Smart Ideas for Your Business energy efficiency program, which provides financial incentives and technical assistance to ComEd customers to help them become more sustainable.

CenturyLink Technology Solutions initiated the multi-year project to upgrade and overhaul the majority of CH2’s mechanical equipment, serving the 125,000-sq-foot data center. This project will help the company reduce the power usage effectiveness (PUE) of CH2. A CenturyLink spokesperson would not provide the current PUE for the data center or the PUE the company hopes to achieve, saying “We do not publish our PUE figures externally.”

In addition to improving energy efficiency, CenturyLink will use the financial incentives from ComEd to upgrade data center CRAC units with variable frequency drives, improve cooling tower performance, optimize data center operating temperatures, and airflow management.
