Why NH & ME Homeowners Are Installing Generators

Power Outages Here Are Not a Rare Event

New Hampshire sits in one of the most storm-affected corridors in the country. Ice storms, nor'easters, and summer Derecho events knock out power for thousands of homes every year - sometimes for multiple days at a stretch. The White Mountains funnel brutal winter weather directly into the seacoast region.

For most NH and ME homeowners, losing power means losing heat (most modern HVAC systems need electricity to run), losing water from well pumps, and losing refrigerated food. For families with medical equipment, the stakes are even higher.

Standby generators eliminate that vulnerability entirely. They detect an outage and kick on automatically within seconds - no action needed from you, whether you're home or away.

Not all generator installs are equal. A standby generator connects directly to your home's electrical service and gas supply. It requires a licensed Master Electrician to size the system, install the transfer switch, and pull permits. This is not a job for a general handyman or an unlicensed contractor - and NH state law agrees.

What a Generator Protects

  • Heating & cooling systems (HVAC, heat pumps)
  • Well pump & water supply
  • Refrigerator & freezer
  • Medical equipment & devices
  • EV charger & sump pump
Know the Difference

Standby vs. Portable Generators

Before committing to any generator, it helps to understand what each type actually does - and what it doesn't.

Portable Generator
  • Lower upfront cost
  • Portable, can be stored away
  • Manual start - you must be home
  • Requires gasoline - supply may be limited in storms
  • Powers limited circuits only
  • Carbon monoxide risk if used improperly
  • Does not add home value
Good for temporary, limited backup. Not a long-term solution for NH storm seasons.
Recommended
Standby Generator
  • Turns on automatically within seconds
  • Runs on natural gas or propane - no fuel runs
  • Powers your whole home or all critical circuits
  • Works whether you're home or away
  • Permanent installation, adds home value
  • Runs self-tests weekly
  • May qualify for federal tax credit
If you want true whole-home backup power that turns on automatically when the grid fails, standby generator installation is the right choice.
The Installation Process

What a Professional Generator Installation Includes

Moore Electric handles every step from initial sizing through final inspection. Here's what's included in every installation.

01
Electrical Load Assessment

Brenden reviews your panel and calculates your home's exact power needs to size the right generator - not too small, not oversized.

02
Transfer Switch Installation

Moore Electric installs an automatic transfer switch (ATS) that detects an outage and switches your home to generator power within seconds.

03
Permit Pulling

Every generator installation in NH requires an electrical permit and state inspection. Moore Electric pulls all permits - many contractors skip this, creating legal and insurance issues.

04
Utility Coordination

For natural gas connections or propane tank siting, Moore Electric coordinates with your utility and propane supplier to ensure proper fuel supply.

05
Generator Placement & Mounting

Generator pad or mounting installed to NH code requirements. Proper placement accounts for clearances, exhaust direction, and long-term serviceability.

06
Startup & Walkthrough

Brenden personally starts the system, verifies everything is running correctly, and walks you through how your generator operates and self-tests.

Authorized Installer

Generac Generator Installation

Generac is the most recognized standby generator brand in the country - and for good reason. Their home standby systems are engineered specifically for residential use, come in a wide range of sizes, and include remote monitoring through the Mobile Link app so you can check your generator's status from anywhere.

Moore Electric installs Generac standby generators throughout Southern NH and Northern MA. When you call a licensed Master Electrician rather than a general contractor or handyman for this installation, you're protecting both the warranty and the long-term reliability of the system.

Generac's warranty requires installation by a licensed electrician. An unpermitted or improper installation voids manufacturer coverage and can create serious liability for the homeowner.

What Happens Without a Licensed Installer
  • Generac manufacturer warranty is voided
  • NH state law requires a licensed electrician for transfer switch work
  • Homeowners insurance may not cover fire or damage from unpermitted work
  • Improper transfer switch installation creates serious backfeed hazards for utility workers. If you notice electrical issues after an unpermitted install, call a licensed electrician immediately
  • Problems discovered at resale when unpermitted work surfaces during inspection
Generator Sizing Guide

How Do You Know What Size You Need?

Generator sizing depends on your home's square footage, load requirements, and which circuits you need to keep running. Here's how most projects break down.

10-16 kW
Essential Circuits
Critical loads only - keeps your heat, well pump, refrigerator, and lighting running. Good for smaller homes or projects focused on the most important systems.
Powers 8-12 critical circuits
24-26 kW+
Large Homes & High-Load
Large homes, or homes with well pumps, EV chargers, heat pumps, and high-demand appliances all running simultaneously.
EV charger homes often fall in this range

Natural gas vs. propane affects both upfront and ongoing cost. Homes on natural gas typically have lower fuel costs. Propane requires a tank installation but is widely available in rural NH and ME. Some homes may also need a panel upgrade before a generator can be added - Moore Electric can assess both in the same visit.

What Affects Your Price

Generator Installation Cost in NH - What to Expect

Every home is different, so every generator project is priced based on your specific situation - the size of the system, your existing electrical setup, and what's needed to do the job right. Brenden walks through all of this during a free on-site assessment before any numbers are put on paper.

The biggest factors that influence your final price:

  • Generator Size & Brand

    Larger generators and premium models cost more upfront but typically offer better reliability and warranty coverage.

  • Transfer Switch Type

    Automatic transfer switches cost more than manual, but are standard for standby systems and worth every dollar.

  • Gas Line or Propane Tank

    Homes without existing natural gas may need propane tank installation or gas line trenching, which adds to the total.

  • Panel Capacity

    Some older homes need a panel upgrade before a generator can be properly integrated. Moore Electric can quote both together.

Federal Tax Credit Available

The Inflation Reduction Act's Energy Efficient Home Improvement Credit offers 30% back (up to $600) on qualifying panel upgrades that support generator-ready infrastructure.

Ask Moore Electric about tax credit eligibility during your assessment visit.

Common Questions

Generator Installation FAQs

Yes. In New Hampshire, generator installation requires an electrical permit and state inspection by a licensed Master Electrician. Transfer switch installation must be performed by a licensed electrician - it's not optional. Moore Electric handles all permitting as part of every installation.

A manual transfer switch requires you to physically flip a switch when the power goes out. An automatic transfer switch (ATS) detects the outage and switches to generator power within seconds - no action needed. For a true standby system, an automatic transfer switch is standard.

Most residential standby generator installations take 1-2 days for the electrical work. If propane tank delivery or gas line extension is needed, that may add additional time for the gas contractor's portion. Moore Electric coordinates the full timeline so you know what to expect.

Not legally in New Hampshire. Transfer switch installation must be performed by a licensed electrician. Unpermitted installations void manufacturer warranties, may void your homeowners insurance, and create serious backfeed hazards for utility workers. The savings are not worth the risk.

Yes. Moore Electric installs Generac standby generators throughout Southern NH and Northern MA. Generac is the most widely used residential standby brand, and Moore Electric's Master Electrician license ensures the warranty and installation are both fully compliant.

Some older homes do need a panel upgrade before a generator can be added correctly. Brenden assesses your panel during the free on-site visit and can quote both the panel work and generator installation together if needed.

Yes, but sizing matters. Homes with EV chargers or heat pumps typically need a 24 kW or larger system to run everything simultaneously. Moore Electric's load assessment accounts for all high-draw appliances in your home.
