This winter’s extreme cold snap, which sent temperatures plummeting as low as the 40s below 0 in parts of the Midwest, also put a crunch on the natural gas infrastructure in several areas. In fact, some large facilities such as the Aspirus Langlade Hospital in Antigo, Wisconsin, were asked to switch to propane to help keep the rest of the community warm. The WSAW news network reported that it was easy for the hospital to work with its local propane provider to make the switch. “It’s actually not that involved,” Jason Noskowiak, the facilities manager for the hospital, told the network. “Our systems are set up to be able to do this, so it’s just a matter of going into our boilers and changing some of the programming.” Whether its fueling standby generators or serving as a backup for a building’s heating systems, propane offers an onsite source of fuel that makes healthcare facilities and other buildings with critical energy needs more resilient.
