The stations are licensed by the Alabama Educational Television Commission which was created by the Alabama state legislature in 1953.  (APT). The system protects the broadcaster's transmitter from power disturbances and also conditions the power, providing voltage regulation Voltage regulation

 and harmonic cancellation. The first system was deployed in the fall of 2006 at APT's transmitter site in Spanish Fort Spanish Fort or "Old Spanish Fort" can refer to:

, Ala. The second system was recently deployed at another transmitter site in Texasville, Ala.

"APT is a network of public broadcast service member stations that serves the entire state of Alabama so transmission interruptions due to power disturbances are simply not an option," said Gary Rackow, vice president, Americas for Active Power. "Weather or electrical events that cause downtime The time during which a computer is not functioning due to hardware, operating system or application program failure.  can result in lost viewers, but also lost sponsorship revenue. In emergency situations, continuous power is critical as state residents rely on APT for important information. Active Power's CleanSource system is ideal for protecting transmitter sites due to its higher reliability over conventional battery based UPS systems."

Active Power's flywheel technology is proven in broadcast applications with systems deployed in more than 20 U.S. states A U.S. state is any one of the fifty subnational entities of the United States, although four states use the official title "commonwealth". The separate state governments and the federal government share sovereignty, in that an American is a citizen both of the federal entity and  to protect transmitter sites and broadcast studios against power sags, fluctuations and outages. CleanSource has a lower total cost of ownership as compared to a conventional battery based system because of lower installation and maintenance costs and reduced utility costs due to its higher energy efficiency.

The system is also inherently more reliable in broadcast environments, particularly during crowbar events. This event is an automatic shutdown method used in many high power transmitters as a safety circuit, which can wreak wreak
