Small-business owners can face serious financial devastation when a power outage strikes, as has happened recently. When a business loses power, it may take hours, days or even weeks to restore and generate profitable revenues again. The total cost of the disruption can include lost business, the cost of repairs, and the cost of equipment, materials or services used for temporary repairs. Lost revenue is often the biggest hit, as customers may choose to go elsewhere while the power is out, resulting in lost sales. Business owners may also have to purchase replacement products or materials to make up for lost days of production. Businesses may also incur overtime cost for employees and the cost of purchasing emergency services such as generators. Additionally, businesses may need to invest in more reliable power backup solutions in case a similar situation happens in the future.
