No gas line? No problem.

Large parts of Charles County — Nanjemoy, Charlotte Hall, Hughesville, rural Pomfret and Marbury — never got natural gas service, and aren't getting it. For these homes, propane is the standby fuel, and it works beautifully: it doesn't degrade in storage like gasoline, it delivers the generator's full rated power, and a properly sized tank carries you through the longest realistic outage.

Tank sizing: the key decision

This is where propane installations are won or lost. A 20 kW generator at half load burns roughly 2–3 gallons of propane per hour. A 250-gallon tank (200 usable gallons — tanks fill to 80%) gives you about 3–4 days. A 500-gallon tank (400 usable) gives you about a week. We size the tank against the outages you actually worry about: for most Southern Maryland homes, 500 gallons is the sweet spot — it covers a derecho-scale event with margin. Going bigger is cheap insurance if you have the yard space.

Placement and code

Propane tanks have placement rules: minimum distances from the house, from ignition sources, from property lines — the specifics depend on tank size and local code. We handle the layout, the permits, and the trenching for the underground line from tank to generator. Above-ground tanks are the norm for residential standby; we set them on a proper pad or blocks, level and anchored.

The full package

One job covers everything: tank procurement and placement, gas line from tank to generator, generator installation, transfer switch, electrical, permits, and coordination with your propane supplier for the first fill. After installation, the routine is simple: keep the tank full going into storm season (June), and your supplier tops it off after any significant outage use.

Frequently Asked Questions

What size propane tank do I need?

For most homes with a 20 kW-class generator, a 500-gallon tank is the recommendation — roughly a week of runtime at typical loads. We'll calculate it against your generator size and the outage lengths you want to cover.

Can I use my existing propane tank?

Sometimes — if it's large enough and in good condition. A 100-gallon tank that feeds your fireplace won't run a standby generator for long. We'll evaluate what you have during the assessment.

How do I get propane delivered during a long outage?

Call your supplier as you would normally — but during widespread outages, deliveries can be delayed. That's why we recommend sizing the tank to cover the outage without a mid-event refill.

Does propane go bad like gasoline?

No — that's one of its big advantages. Propane doesn't degrade, gum up, or grow stale. The fuel in your tank is good whether you use it next month or next year.
