May on the northern plains means wind, warm fronts, and the first serious severe weather watches of the year. Utility lines that survived winter get tested again, and homeowners start wondering whether their standby generator will start on the first try when the grid drops.
Prairie Power - Generator Solutions treats May storm weeks as a planning season—not a panic season. A few disciplined exercise and maintenance habits now prevent most of the emergency calls we field in June.
Exercise under load, not idle only
Standby units need exercise that includes transfer switch behavior, not only a brief idle run. Note whether weekly tests complete under load and whether run hours advance the way your manual describes.
Idling alone does not prove the unit will carry kitchen refrigeration and sump pumps when utility power drops. If your last exercise sounded rough or ended with an alarm, schedule service before the next front.
Fuel stability between storm weeks
For propane and natural gas systems, fuel margin matters when outages cluster. Document last service dates and keep vendor records where a family member or house sitter can find them.
Write tank percentage with today’s date. May grill nights and automatic exercise cycles both draw from the same propane supply. Running low before a storm week is an avoidable problem.
Priority circuits that match real life
Your priority circuit list should reflect what the household actually uses during an outage: refrigeration, sump pumps, well pumps, medical equipment, and at least one safe lighting path.
If you added loads since last season—EV charging, shop circuits, pool equipment—mention them at your next service visit. Transfer sizing was set at installation; meaningful changes deserve a professional review.
Transfer switch warning signs
The automatic transfer switch should transfer smoothly during exercise. Hesitation, buzzing, or failed transfers belong in licensed hands before the next outage.
You can visually inspect for damage or pest activity. Do not open energized equipment. Call 701-935-3617 or use contact when something looks or sounds wrong.
Maintenance before schedules compress
Oil, filters, starter battery, and coolant checks belong on the calendar before heat and storms tighten everyone’s schedule. Deferred maintenance shows up as failed exercise cycles on the hottest afternoon of the season.
Customers on Essential Annual, Preferred Semi-Annual, or Premier Uptime can align professional visits with the same rhythm. See service plans for tier details.
