ABB invests in technology for data center energy efficiency

Major stake in Validus DC Systems provides innovative electrical distribution technology that lowers total facility costs by up to 30%


ABB has purchased a controlling interest in US-based Validus DC Systems, a provider of direct current (dc) power infrastructure equipment for energy-intensive data centers.

DC technology is allegedly more energy efficient than traditional alternating current (ac) technology for electrical distribution. DC systems are reportedly less complex, requiring less space and equipment, resulting in considerable additional savings in real estate and capital expenditure. The investment in Brookfield, CT-based Validus complements ABB’s strong technology platform to bolster its entry into the $24 billion market for telecommunications and data center power infrastructure.

“DC systems provide data centers with a game-changing advantage in both operational and capital cost savings and we believe they will be widely adopted in this energy-intensive industry,“ said Tarak Mehta, head of ABB’s Low Voltage Products division.

Data centers can use 100 times more electricity than a similar size office building. DC technology can improve their energy efficiency by 10 to 20 percent compared with AC systems by trimming power conversion losses, reported ABB. It also reduces power equipment, installation, real estate and maintenance costs, resulting in a saving on total facility costs of up to 30 percent.

“With ABB’s strong financial backing, their long-term experience in DC technology in other industries, as well as their highly-skilled technical support and vast market reach, we can quickly expand the availability of our DC systems to cost-challenged data centers worldwide,” said Rudy Kraus, Chief Executive Officer of Validus DC Systems. “This end-to-end solution will help facilities save millions of dollars in energy and installation costs without sacrificing reliability.”

This is ABB’s second recent investment in technology related to data center power infrastructure following the September 2010 investment in Power Assure, a developer of power management and optimization software for data centers.

The investment in Validus DC Systems was made through ABB Technology Ventures, the company’s venture capital arm, which invests in strategically interesting early and growth stage companies. ABB has also made VC investments in companies working in electric vehicle charging infrastructure, smart grid communications, wave power generation, cyber security for utilities and wind farm efficiency.

Both parties agreed not to disclose financial details of the transaction, which includes an option for ABB to fully acquire Validus.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
