Back-up generators allowed many farms in Mississippi and Louisiana to continue milking despite widespread electrical outages caused by Hurricane Katrina.

While producers in other states may not face hurricanes, they often do face thunderstorms, tornadoes and ice storms.

“Investing in a standby generator is like paying for insurance,” says Michael Kawleski, manager of the agriculture department at Wisconsin Public Service. “You hope you never have to use it, but if you do need it, it is well worth the price.”
