Plymouth Generator Installation & Service
Authorized Kohler, Cummins & Briggs & Stratton generator installation for Plymouth homes and businesses. We are right down the road — headquartered here in Marshall County since 1963.
Plymouth Generator Installation by Your Home-Base Team
Banner Electric is headquartered in Plymouth, and that matters when you need generator service. We are not dispatching from another county — our trucks and technicians are already here. Many Plymouth homes carry pre-1970 electrical panels that need an upgrade before a generator can be safely installed, and our team handles the panel work and the generator installation together, cleanly and on code.
As an authorized Kohler, Cummins, and Briggs & Stratton dealer, we handle everything: load calculation, sizing, gas line coordination, installation, permitting, inspection, and ongoing maintenance. One call covers the whole job.

Why Plymouth Trusts Banner Electric for Generator Work
Being headquartered here means we know Plymouth — the older homes that need panel upgrades before a generator can go in, the newer subdivisions that are already wired for it, and the local permit requirements. When you call Banner Electric for a generator in Plymouth, you get a crew that is right down the road, not one routing calls through a regional dispatch center.
Whether you need a 22kW whole-home generator or a 150kW commercial unit, we have the manufacturer authorization and 60-plus years of local experience to handle it. Every installation comes with a full warranty backed by both Banner Electric and the manufacturer.
Frequently Asked Questions
How much does a standby generator cost in Plymouth?
Residential standby generators typically range from $5,000 to $15,000 installed, depending on size and fuel type. If your Plymouth home needs a panel upgrade first, we include that in the estimate so you see the full cost upfront. Commercial units vary based on power requirements. We provide free, no-obligation quotes for every project.
Do I need a permit for a generator in Plymouth?
Yes. Generator installations in Plymouth and Marshall County require electrical and sometimes gas permits. Banner Electric handles all permitting and inspections as part of every installation — you do not need to manage any of that.
How long does generator installation take?
Most residential generator installations are completed in one to two days. If a panel upgrade is also required, we schedule both together to minimize disruption to your Plymouth home.
What size generator do I need?
It depends on your critical loads — HVAC, refrigeration, sump pumps, medical equipment, and more. Our electricians perform a detailed load analysis at your Plymouth property and recommend the right size. Oversizing wastes money; undersizing leaves you without the protection you need.
