1. Before the Snow Falls: Your Must-Do Prep
Winter readiness starts long before the first flakes hit the ground. Focus on giving your generator the best environment to operate safely and efficiently.
Keep Clearance Clear (The 3-Foot Rule)
Your generator needs at least three feet of open space on all sides to breathe and exhaust properly. As snow builds up, keep the area clear of drifts, leaves, and ice. Proper airflow = reliable performance.
Consider Elevation & Wind Protection
Live in an area with heavy accumulation? A raised platform helps keep the unit above drifting snow. For regions with harsh winds, adding a windbreak at a safe distance can protect the enclosure without limiting airflow.
Fuel System Check (LP & Natural Gas)
-
Natural Gas: Typically winter-tough, but in regions less familiar with deep freezes, moisture in the gas stream can cause unexpected issues.
-
Liquid Propane (LP): LP needs pressure to vaporize correctly. In extreme cold, that pressure can drop, which makes powering larger loads difficult. If you’re on LP, schedule a fuel delivery before the storm. It’s one less thing to worry about—and it helps avoid emergency delivery costs.
Inspect the Mechanicals
A quick visual check goes a long way. Look for loose connections, fuel or oil leaks, and make sure your battery is charged with clean terminals.
Follow Winter Readiness Guidance
NERC recommends generator owners complete winter checklists, deploy weatherization measures in advance, and monitor ongoing cold-weather mitigations. Being proactive can help reduce the risk of outages during extreme demand events.
