Active Power's Flywheel UPS Delivers Steady State Power to WFFF

Highly Reliable Solution Ensures Program Availability

AUSTIN, Texas, April 17 /PRNewswire-FirstCall/ -- Active Power (NASDAQ:ACPW), the inventor and manufacturer of the most reliable and energy-efficient critical power systems in the world, announced today that it is providing critical backup power to WFFF & WVNY, Fox and ABC affiliates, respectively, in Burlington, Vermont. When the stations embarked on their Digital TV (DTV) build out they had two goals in mind: the first to deliver the highest quality television service available and the second to create a very reliable service infrastructure, without interruptions, for their viewers. WFFF chose Active Power as its partner to ensure the second goal became a reality.

"We felt the CleanSource(R) UPS system was a more affordable solution with lower maintenance than conventional battery-based UPS systems," said Matt Servis, Director of Engineering for WFFF. "We installed the system six months ago and it was evident right away that we had made the right choice. We've had over two-hundred power incidents in this timeframe with absolutely no interruption in service to our viewers. This machine is just a workhorse."

"Active Power is pleased to be able to work with WFFF on its mission-critical infrastructure," said Jim Clishem, President and CEO of Active Power. "Broadcasters have very little margin for error when delivering programs to their customer bases, as there are high expectations that services will always be available. We are happy to be part of the solution that helps to enable this performance level for WFFF."

Active Power's CleanSource UPS system offers broadcasters a highly reliable alternative to conventional power solutions. Broadcasters across the world have selected the company's integrated flywheel-based UPS system for its small footprint, low maintenance, high reliability, 20-year product life, extreme energy efficiency, and temperature indifference. It is the most compelling choice in backup power solutions available in the market today.
