Active Power (ACPW) to Provide Continuous Critical Backup Power at 2011 Nordic World Ski Championships

Jan. 12, 2011 (Business Wire) — Active Power (NASDAQ: ACPW) will deploy its PowerHouse system, a continuous critical infrastructure solution onsite for the 2011 Nordic World Ski Championships, being held February 23 through March 6, 2011, in Holmenkollen, Norway. The 40 foot, 400 kW containerised power infrastructure system will provide complete power conditioning and protection for the event’s international broadcast centre (IBC). The system will be integrated and tested at Active Power’s facility in Evesham, England, and then delivered to the customer site in January 2011.

“The local government of Oslo required a complete turnkey power solution that could condition utility power to the IBC, but also supply longer term power in the instance of a mains failure,” said Jon Vidar Berg, sales engineer, Energyst CAT Rental Power, Norway, who served as the contractor on the project.

“Just as important though, winters in Oslo can be extremely cold so we needed rugged power infrastructure equipment that could withstand temperatures as low as minus 25 degrees Celsius. In these conditions, conventional UPS (uninterruptible power supply) technology would require a heated enclosure. Active Power’s PowerHouse system, with its flywheel UPS, is flexible enough to operate under these conditions.”

With more than 300,000 spectators expected to attend and millions more to watch on television and via the Internet, the 2011 Nordic World Ski Championships is one of the most popular winter games event in Scandinavia. The event will hold more than 20 cross country, Nordic combined and ski jumping events in Holmenkollen. Due to the increased media attention at the games, the IBC will manage all communications and broadcast feeds to television and online networks across Scandinavia.

“Our PowerHouse system is a perfect fit for this particular application in Oslo,” said Jim Clishem, president and CEO at Active Power. “The containerised solution offers all critical physical infrastructure components – high efficiency flywheel UPS, diesel generator, switchgear and monitoring and controls software – in one streamlined package. The solution is made up of manufactured components and is preconfigured and pretested prior to deployment, providing better performance, quick delivery and tangible economic benefits versus other alternatives.”
