Prepared for any contingency

Reliable, safe and durable, Avail Emergency Mobile Substations are a critical component to effective power recovery. Avail delivers a range of convenient solutions – all designed to restore or deliver power wherever you need it and as fast as you need it. Our trailer, skid and platform mounted Medium Voltage Switchgear can be designed to fit your needs, including:

• 5kV-38kV metal-clad switchgear
• 5kV-38kV Metal-Enclosed Interrupter (MEI) switchgear
• 5kV, 250MVA / 15kV 750MVA multi-rated switchgear
• Tamper-resistant M/C or MEI switchgear (IEEE C57.12.28)

Recently, Congress found that the storage of strategically located spare large power transformers and emergency mobile substations will reduce the vulnerability of the United States to multiple risks facing electric grid reliability, including physical attack, cyber attack, electromagnetic pulse, geomagnetic disturbances, severe weather, and seismic events. As a result, H.R. 22, the “Fixing America’s Surface Transportation Act” (FAST Act), includes several measures aimed at firming the U.S. electric grid against a variety of attacks and outages. The legislation was signed into law in December 2015, and is intended to develop a strategic reserve of transmission equipment, including transformers and Emergency Mobile Substations. To assist with compliance of this important piece of legislation, Avail is proud to offer Emergency Mobile Substations that are available fully assembled and permanently mounted on a trailer that is capable of highway travel and meets relevant Department of Transportation regulations and; Is intended for express deployment and capable of being rapidly placed into service.

Emergency and non-emergency solutions

Avail Emergency Mobile Substations and Portable Substations are invaluable when unexpected outages occur, and they also provide a wide range of applications and benefits that extend beyond unexpected outages:

• Small footprint
• Minimizes site preparation
• Switchgear to help extend transformer life
• Replace 5KV 26” air magnetic breakers with vacuum
• Tamper-resistant options
• With or without transformers
