ABB will design and install an advanced direct-current (DC) power distribution system for green.ch, an information and communications technology service provider in Switzerland.

DC technology trims power conversion losses and is 10% to 20% more energy efficient than traditional alternating-current technology for electrical distribution in data centers. DC systems are also less complex and require less space, reducing equipment, installation, real estate and maintenance costs.

ABB will install a fully redundant 1-MW DC power distribution solution for the 1,500-sq m (16,146-sq ft) expansion of the existing 3,300-sq m (35,520-sq ft) data center. It will be designed and engineered to green.ch's stringent ecological standards by Validus DC Systems, an ABB company. The order includes a service-level agreement, and the expansion is scheduled to begin commercial operation in the first quarter of 2012.

Located in Lupfig, in north-central Switzerland, the green.ch data center provides customers with secure storage and data management capabilities. The green.ch data center has been selected as ABB's demonstration site for its new DC technology.
