In the aftermath of the derecho, several hospitals and nursing homes relied on generators as Appalachian Power Co. worked to restore power.

It took hours in some cases and days for others.

In all nine hospitals in Southwest Virginia lost power including, according to the Virginia Department of Health:

• LewisGale Hospital Alleghany
• Carilion Giles Community Hospital
• Carilion Franklin Memorial Hospital
• Memorial Hospital of Martinsville & Henry County
• Catawba Hospital
• Lynchburg General Hospital
• Virginia Baptist Hospital
• LewisGale Hospital Pulaski
• Bath Community Hospital

All the hospitals had power restored by Monday. Giles hospital was on generator power until Monday, said Carilion Clinic spokesman Eric Earnhart. The hospital in Pulaski, however, didn’t lose power during Friday’s storm but in the subsequent storm that hit just after midnight Monday, LewisGale spokeswoman Joy Sutton said.

Throughout the region that stretches from Roanoke west to the New River Valley and east to Lynchburg, 18 long-term care facilities went dark or had to rely on generators for power. At one point, Roanoke officials discussed the possibility of evacuating Friendship Retirement Community’s nursing home.

These major health care providers will be adding up the costs of the storm over the next couple of weeks.

LewisGale Regional Health System provided me with an early indicator of the cost at the two hospitals that lost power by looking at the fuel costs. In Pulaski it cost $667 to run on generator power for 11 hours and 30 minutes. In Alleghany the cost of running the generator for 9 hours and 30 minutes was $1,515.
