Hurricanes, floods, snow storms, and other natural disasters can all cause massive power outages, taking weeks if not longer to restore. In the past, the loss of electrical power also meant the loss of your climate control system. While your building’s temporary power may keep the lights on when the power goes out, it is often not strong enough to power your HVAC systems fully or for very long. Storm survivors may end up with no relief for the hot, humid, stifling conditions following a hurricane or tropical storm and no escape from freezing temperatures after a blizzard or ice storm. The loss of HVAC systems from a prolonged electrical power outage can cause greater damage to your goods and more injury to your employees than your business may have experienced in the storm, delaying recovery and extending the business interruption. That is, until now.
