Active Power, Inc. designs, manufactures, and sells flywheel-based uninterruptible power supply (UPS) products and modular infrastructure solutions (MIS). The company’s products and solutions are based on its patented flywheel and power electronics technology and are designed to ensure continuity for data centers and other mission critical operations in the event of power disturbances. The company’s products and solutions are designed to deliver continuous conditioned (clean) power during power disturbances and outages, voltage sags and surges, and provide ride-through power in the event of utility failure, supporting operations until utility power is restored or a longer term alternative power source, such as a diesel generator is engaged. As of December 31, 2013, the company had shipped approximately 4,000 flywheels in UPS systems, delivering approximately 900 megawatts of power to customers in approximately 50 countries worldwide, providing approximately 150 million runtime hours of operation. The company designs, manufactures, and sells modular power infrastructure products that integrate its UPS products with other related equipment, including switchgear and automatic transfer switch; monitoring and controls; analytics software; fire detection; lighting; security; and air conditioning. Its integrated product is sold as a power solution for customers, which the company calls CleanSource PowerHouse. Products: UPS and MIS UPS CleanSource UPS The company’s UPS products serve two primary functions. First, during normal operations they are continuously conditioning (cleaning) the incoming power from the utility and delivering ‘conditioned’ power to the client’s mission critical load (information technology (IT) equipment, etc.). In this mode, the UPS regulates incoming utility power fluctuations in voltage and frequency. Second, if there is any interruption in the utility source, the UPS would provide temporary, or bridging power, until either the utility power is restored or an alternative generating source, such as a diesel generator, begins to provide power. The company offers an integrated flywheel UPS product, which integrates UPS power electronics with flywheel energy storage technology. The flywheel stores kinetic energy – energy produced by motion – by spinning a compact rotor in a low friction environment. When short-term backup power is required due to utility power fluctuations or losses, the rotor’s inertia allows it to continue spinning and the resulting kinetic energy is converted to electricity. The company markets its flywheel-based UPS systems under the brand name CleanSource UPS. CleanSource UPS is a battery-free UPS system that integrates proprietary UPS electronics and the company’s flywheel energy storage system into one compact cabinet lineup. The company offers CleanSource UPS products in power configurations ranging approximately 1.5 MVA (million volt amps) with the ability to parallel these products to provide approximately 8 megawatts of load protection. Combining CleanSource UPS with a generator provides customers with complete short- and long-term protection in the event of a power disturbance. CleanSource 750/625HD UPS The company offers its CleanSource 750/625HD UPS, which is available in standalone modules rated at 750 kVA (kilo-Volt-Amps or power level) and 625 kVA for 60 and 50 Hertz applications, respectively. This system could be paralleled together to provide approximately 5 MVA of protected power. The product’s design allows for the use of auxiliary batteries in the event the customer requires extended, autonomous run time for certain applications. MIS CleanSource PowerHouse For customers looking for an integrated continuous power system, the company packages its CleanSource UPS along with switchgear and automatic transfer switch; monitoring and controls; analytics software; fire detection; lighting; security; and air conditioning into an integrated system. Due to the space efficiencies of its UPS products, the company is able to offer all of these components in a pre-packaged containerized solution offering that it markets under the brand name Cle
