Generator Installation Cost in Myrtle Beach, SC
A fully installed whole-house standby generator runs $9,000 to $25,000 here, and a transfer switch for a portable unit runs $500 to $1,700. The spread comes from generator size, fuel type and site work, not a fixed markup.

How much does generator installation cost in Myrtle Beach, SC?
That's a wider range than a lot of national cost guides quote, and there's a real reason for it: this market's mix of coastal siting requirements, hurricane-driven demand, and a meaningful share of properties without natural gas service pushes typical Grand Strand pricing above a generic inland average.
What moves it
What Changes the Price: Size, Fuel Type, Siting
Kilowatt size is the biggest single factor. A 13-17kW unit covering essential circuits runs $9,000 to $14,000 installed; a 20-26kW-plus unit sized to also run central air runs $14,000 to $25,000. The jump isn't just a bigger engine — it's a larger transfer switch and, often, a bigger fuel connection too.
Fuel type is the second lever. Natural gas is usually the cheaper connection when it's already available, since there's no tank to buy or site. Propane, common across much of the Grand Strand where gas utility service doesn't reach, adds $1,500 to $4,000 for a properly sized and sited tank.
Siting is the piece a national cost calculator misses entirely. Within a few miles of the ocean, flood-elevation pad requirements and corrosion-resistant equipment specs can add $1,000 to $4,000 over an inland installation with an otherwise identical generator. An HOA screening requirement, common in gated Grand Strand subdivisions, adds a homeowner cost on top of that, separate from the installer's own quote.
Side by side
Portable + Interlock vs. Whole-House Standby Cost
| Approach | Typical upfront cost | Notes |
|---|---|---|
| Portable generator + interlock kit | $300-$900 (switch only, plus $500-$2,500 for the generator itself) | Cheapest code-legal option; requires someone present to run it |
| Portable generator + manual transfer switch | $1,200-$1,700 (switch only) | Dedicated sub-panel with individual circuit switches |
| Standby generator, essential circuits (13-17kW) | $9,000-$14,000, fully installed | Starts automatically; covers sump pump, fridge, furnace blower |
| Standby generator, whole-home (20-26kW+) | $14,000-$25,000, fully installed | Adds central air and most remaining circuits |

What you get
What's Included in the Quote vs. What's an Add-On
- Included in a standard quoteLoad calculation, the generator and standard transfer switch, a code-standard pad, a typical-length fuel connection, permit filing and the commissioning test.
- Common add-ons: long fuel line runsTrenching beyond a typical distance from the meter or tank adds $500 to $2,500.
- Common add-ons: coastal siting requirementsFlood-elevation pad work or corrosion-resistant enclosures near the ocean add $1,000 to $4,000.
- Common add-ons: gas meter upsizingIf the existing meter doesn't have spare capacity for the generator's draw, a utility upsize adds $1,000-plus and its own scheduling timeline.
- Not the installer's cost: HOA screeningFencing or landscaping to screen the unit from street view is typically a homeowner cost, separate from the installation quote.
Timing note
Why June Pricing and September Pricing Aren't the Same Conversation
A quote requested in late winter or early spring, ahead of the June 1 start of hurricane season, is a normal-lead-time conversation: equipment is generally available, permit desks aren't backed up, and installers have open scheduling slots.
A quote requested once a storm is already in the forecast is a different situation entirely. Generator demand spikes, popular kW sizes can sell out regionally, and installer schedules fill fast. Pricing itself doesn't necessarily go up on a per-unit basis, but availability tightens, and a rush install (if one's even possible) isn't the same timeline as a planned one.
The honest takeaway isn't 'buy now out of fear.' It's that if you're already leaning toward a standby system, scheduling the load-calculation visit in the off-season gets you a normal process instead of a compressed one.
Straight answers
How much does a whole-house standby generator cost installed?
$9,000 to $25,000 in Myrtle Beach, with kilowatt size and fuel type as the two biggest factors, and coastal siting requirements pushing toward the higher end near the ocean.
Does the price include the concrete pad and gas or propane connection?
A standard-length pad and fuel connection are typically included in a whole-house standby quote; a longer fuel line run, a meter upsize, or a new propane tank are common add-ons quoted separately once site conditions are confirmed.
Why do generator prices go up right before hurricane season?
It's less about per-unit price and more about availability. Demand spikes, popular sizes can sell out regionally, and installer schedules fill up, which is why booking in the off-season gets a normal timeline instead of a compressed one.
Is a portable setup with a transfer switch actually cheaper long-term?
Upfront, yes, significantly. Long-term, it depends on how often you'd actually use it and whether someone's reliably available to run it. A portable setup has essentially no fixed ongoing cost beyond fuel and occasional maintenance, but it also can't run itself.
