Lowes is different than a supermarket -- they have no perishable merchandise. They don't need a huge generator to operate safety systems and the POS. Although some merchandise is sensitive to cold, it doesn't take much electricity to run the blower motors if they have natural gas heat.
It's also important to consider that network communications will also go down and a suitable backup should be available. That's why the crisis response team should also have a SATCOM or wireless alternative for payment auths.
