CenturyLink Enhances Performance with Efficiency Measures

Fortune 500 company and global IT leader CenturyLink has implemented projects to enhance energy savings and Power Usage Effectiveness (PUE). This initiative includes separate “environments” (caged or fenced-off areas) for each of its more than 100 customers. CenturyLink also instituted a hot aisle/cold aisle containment system to manage airflow, specified to meet individual customer needs.

 

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

Secure design assistance and Savings By Design incentives to offset investment costs for greater energy efficiency. Incentives are achieved by exceeding Title 24 Energy Efficiency codes.

Additionally, our Economic Development Services (EDS) team along with Edison Carrier Solutions can help you find sites with available power, fiber and secure state and local incentives to attract, retain or expand your data center.

Lighting and Controls

Here are some tips on improving energy efficiency and managing your lighting costs.

More Less
  • 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.

Cooling

Maximize your energy-saving by effectively managing your air-conditioning systems. Here are some potential solutions for your business:

More Less
  • 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.

Our Fiber Optic Network - Expand Your Choices

Edison Carrier Solutions, a unit of SCE, owns and operates a 5,000+ route miles of fiber optic network, one of the largest in Southern California, to support critical utility operations. In partnership with the Data Center Team, this fiber is available for lease a lit solution or via a dark fiber lease. Below are some key highlights:

  • Designed, constructed, and operated extensive telecommunications systems to support 14 million people in a 50,000+ square-mile area of Southern California.
  • Infrastructure can be used for antenna attachment and equipment colocation.
  • 890+ substations, 14,000 towers and steel poles, 900 existing cell- site collocations with fiber backhaul capability.

Demand Response Programs (DR)

With Demand Response (DR) programs, you can receive bill credits for temporarily reducing energy use during periods of high-energy demand. Choose the option that best fits your operational needs.

Automated Demand Response (Auto-DR)

Enjoy energy savings by using smart technology that effortlessly and temporarily reduces the amount of energy your business uses (known as “load reduction”) during a DR event. With Automated Demand Response (Auto-DR), load reduction is automatic and reliable, so it’s easier to capitalize on program earnings and lower energy costs.
