What to Expect: The Generator Installation Process Step by Step
Updated July 2026 • 10 min read

Most homeowners have never had a generator installed before and have no idea what to expect. Our installation process is designed to be transparent, minimally disruptive, and complete — we handle everything from permits to utility coordination, so you never have to manage the technical details. Here is exactly what happens, step by step.
Typical Total Timeline
From consultation to fully operational generator: 2–3 weeks. Most of this time is permit processing — once permits are approved, the actual installation takes one day.
The Full Installation Process
Free Consultation (Day 1–2)
We begin with a no-cost, no-obligation conversation about your needs. We discuss: what you want to power (whole house or essential circuits), your fuel preference (natural gas or propane), any medical or special power requirements, and your budget. For most customers this takes 30–60 minutes by phone or video. We can also do an on-site consultation if you prefer.
Site Assessment (Day 2–4)
A technician visits your property to assess: the best generator placement location (considering setbacks, clearances, HOA requirements, and gas line routing), the distance from your gas meter to the proposed generator location, your electrical panel's capacity and transfer switch installation point, any site-specific factors (yard obstacles, HOA requirements, underground utilities, slope). Photos and measurements are taken to prepare an accurate proposal.
Proposal & Approval (Day 3–6)
We prepare a detailed written proposal including generator model and specifications, transfer switch type, all site prep work (concrete pad, gas line, electrical), permit costs, and total installed price. As a 501(c)(3) nonprofit, our pricing is dealer cost — the same price we pay the manufacturer. Once you review and approve the proposal, we proceed to permit filing.
Permit Filing (Day 5–26)
We file all required permits on your behalf. Most installations require an electrical permit and a gas or plumbing permit. Permit processing time is the most variable part of the entire process:
- Rural and smaller municipalities: 1–3 business days
- Mid-size cities (Springfield, Overland Park, Broken Arrow): 5–10 business days
- Large urban permit offices (Kansas City, Tulsa, Tampa): 10–21 business days
- HOA approval (if applicable): 14–45 days — we submit HOA applications alongside permit filings
Site Prep: Concrete Pad & Gas Line (Installation Morning)
The installation crew arrives typically between 7:00–8:00 AM. The first tasks are concrete pad installation (for the generator to rest on) and gas line extension from your meter to the generator location. We call 811 (Dig Safe) before any ground penetration. The concrete pad typically cures adequately within the same day for a modern fast-cure mix. All concrete, gas line, and electrical materials are included in our installation price — there are no hidden site prep costs regardless of gas line distance.
Generator & Transfer Switch Installation (Midday)
The generator unit is positioned on the concrete pad and secured. The automatic transfer switch (ATS) is installed at your electrical panel — this is the device that detects a power outage and automatically starts the generator and switches your home's circuits to generator power. The transfer switch installation requires a brief power interruption to your home (typically 15–30 minutes). All factory-required clearances are maintained throughout installation.
Testing & System Verification (Afternoon)
After all connections are made, we run a complete test sequence:
- Initial startup and idle period (10 minutes)
- Simulated outage: cut power to the home and verify automatic generator startup and transfer switch closure within 30 seconds
- Full load test: air conditioning, refrigerators, lighting, and other loads running simultaneously
- Automatic shutoff test when utility power “restores”
- Review of all wiring, connections, and clearances by lead technician
Customer Walkthrough (Late Afternoon)
Before we leave, a technician walks you through: how the generator and transfer switch operate, the weekly self-test schedule and how to change it, manual start/stop procedures, the initial 8-hour break-in run requirement for new generators, the initial oil change schedule (first change at 20–25 hours of operation), what the generator display panel shows, and how to reach us for service. This walkthrough typically takes 20–30 minutes. We also leave written documentation of everything covered.
Utility Coordination (Following Days)
After installation, we directly contact your gas and electric utilities on your behalf to notify them of the new generation equipment on your property — a requirement in all of our service states. This involves scheduling the utility inspection (where required), completing interconnection paperwork, and confirming that the transfer switch meets the utility's requirements. We have established relationships with all utilities in our service areas and handle this entirely without requiring your involvement.

Frequently Asked Questions
How long does a generator installation take from start to finish?
The total timeline from initial consultation to a fully operational system is typically 2-3 weeks. The breakdown is roughly: Day 1-2 for the free consultation and site assessment; Day 3-5 for proposal review and approval; Day 5-26 for permit filing and approval (this varies significantly by city — some municipalities issue permits in 1 day, others take up to 3 weeks); and 1 day for the actual installation once permits are in hand. Complex installations with long gas line runs or electrical panel upgrades may require additional time.
Do I need to be home during the generator installation?
Yes, we ask that a homeowner or authorized adult representative be present during the entire installation day. You will need to provide access to the electrical panel and gas meter area, verify the generator placement before work begins, and participate in the final walkthrough and system demonstration at the end of the day. Being present also allows you to ask questions as they come up during the process.
What site prep do I need to do before installation day?
Very little — we handle everything. Our crew pours the concrete pad, installs the transfer switch, runs the gas line, and manages all electrical work. Before installation day, you should: clear a pathway from the street to the installation area (wide enough for equipment), note any underground utilities in the work area (our crew calls 811 before any digging), and decide on the final generator placement location based on your site assessment. We handle permits, utility notifications, and all technical work.
What permits are required for a generator installation?
Most generator installations require two types of permits: an electrical permit (for the transfer switch connection to the electrical panel) and a plumbing or gas permit (for the new gas line). In Missouri, Kansas, and Oklahoma, both permits are typically required and processed together. In Florida, requirements vary by county but generally include the same two permit types plus an inspection. Permit processing times range from 1 business day (some smaller municipalities) to 3 weeks (larger city permit offices). Power Up Generator Solutions files all permits on your behalf as part of the standard installation process.
How long does the generator run for on installation day?
After installation, we run the generator through a complete test sequence that typically lasts 1-2 hours. This includes: initial startup and idle period, load testing with your home's electrical system connected, automatic transfer switch test (simulating an outage and confirming automatic switchover), verification that the generator handles startup surge loads (air conditioner, refrigerator compressors, etc.), and a final settings walkthrough. We also program the weekly self-test schedule before we leave.
