Beyond Data Centers

Energizing a subway system to move even faster than Beijing.


Powering a data center as forward-thinking as Facebook itself.

When Facebook began planning a new 300,000-square-foot data center in Forest City, N.C., its goal was to be one of the most energy-efficient data center operators in the world. And with nearly 1.5 billion users worldwide, power reliability was a top priority.

More efficient data centers. For an information-hungry world.


How can I increase efficiency in my data center without sacrificing uptime? Learn how Eaton delivered increased efficiency for Facebook.

Data centers are among the largest consumers of electrical power in the United States, using between 1.7 and 2.2 percent of the nation’s power. Gartner Inc. recently estimated that it cost $1.6 million a year to power an 8,000-square-foot data center. And with the world demanding more and more digital information, those costs are rising 10 percent a year.

The challenge inspired Eaton to think beyond the now and anticipate the industry’s needs for tomorrow.

Putting our expertise to use. For optimal Power Usage Effectiveness.

A critical metric of success for data center efficiency is the Power Usage Effectiveness (PUE) rating. The average PUE for data centers in 2011 was 1.83. But Facebook demanded better.

Eaton had already partnered successfully with Facebook to achieve a PUE of between 1.06 and 1.08 in its Prineville, OR data center. Building on that success and our expertise in energy efficiency and backup power protection, we rolled up our sleeves and helped design a unique solution for the Forest City facility.

Eaton’s Power Xpert 9395 and 9390 uninterruptible power systems (UPS) power and protect Facebook’s networking infrastructure and servers. Both units have the highest efficiency rating (99%), smallest footprint and lowest carbon footprint in the industry.

Setting industry standards with PUEs well below industry averages.

Energy Saver System

Energy Saver System (ESS)
ESS is a mode of operation that allows the UPS to provide 99% efficiency across the entire operating range typically down to 20%. Learn more 

Thanks to Eaton’s Energy Saver System (ESS) technology, Facebook was able to optimize efficiency without compromising protection. ESS continuously monitors incoming power conditions to operate at the highest efficiency level possible, even when lightly loaded—sustaining as much as 15 percentage points better than a traditional UPS—resulting in enhanced power reliability, efficiency and safety.

Forest City is on track to put Facebook at the forefront of energy efficient data center design with a PUE ratio significantly better than industry averages. Next project? Facebook’s data center in Lulea, Sweden.
