CenturyLink Enhances Performance with Efficiency Measures
CenturyLink’s dedication to optimizing air distribution has improved efficiency and lowered energy costs for cooling. By installing airflow management controls with wireless temperature sensors at both Southern California data centers, CenturyLink will see an annual savings of more than 2.1 million kilowatt-hours (kWh).
Take a cue from CenturyLink’s energy-saving achievements. You can apply similar strategies to your business with our Time-Of-Use rates.

Expansion and New Construction
Lighting and Controls
- Install inexpensive occupancy sensors that turn lights off in unoccupied data centers.
- Use LED bulbs and LED exit signs.
- Install dimmable ballasts to lower energy use in fluorescent lamps.
- Install an Uninterruptible Power Supplies (UPS) system to provide emergency power when the input power source fails to provide near-instantaneous protection from interruptions by supplying energy stored in batteries, super capacitors or flywheels.
Your business may already qualify for incentives that could put these energy-saving upgrades into effect.
- Sign up for HVAC maintenance and perform routine maintenance on heating and AC filters, belts, coils and bearings.
- Check that data center cooling meets the latest ASHRAE standards for Datacom environments—many data centers can safely operate at higher temperatures than previous standards.
- Install variable speed drives to optimize fan and pump motor operation.
- In new construction, downsizing mechanical cooling equipment and/or electrical supply can lower costs and mechanical/electrical footprint.
- Install air-or water-side economizers to help cut data center cooling costs by over 60% using standard, commonly available low-cost equipment.
- Uses of best-practices air management, such as strict hot aisle/cold aisle configuration, can double the computer server cooling capacity of a data center.
- Combined with an air-side economizer, air management can reduce data center cooling costs by over 60%.
- For large data center facilities, a chilled water system served by a central plant is the most efficient approach to providing mechanical cooling.
