Commercial Standby Power
For commercial properties, losing power means losing revenue. A properly installed standby generator with an automatic transfer switch (ATS) keeps your critical systems running when the grid goes down.
We install and connect generators for: office buildings and data centers, restaurants and food storage facilities, medical offices and pharmacies, manufacturing and production facilities, retail stores and gas stations, and multi-family residential buildings.
Our commercial generator services include automatic transfer switch installation and wiring, manual transfer switch connections, load management and critical circuit prioritization, generator-to-panel wiring and connections, utility coordination for parallel generation, and permit filing and inspection scheduling.
Residential Backup Generators
A whole-home standby generator keeps your heat, refrigeration, sump pump, and essential circuits running during outages. We handle the electrical connection — the transfer switch, panel connections, and load management — whether you're installing a new generator or connecting one that's already in place.
We work with all major generator brands and can help you size the right generator for your home's electrical demand.
Transfer Switches
The transfer switch is the most critical component in any generator installation. It's what disconnects your building from the grid and connects it to the generator — safely and automatically. We install both automatic transfer switches (ATS) for seamless switchover, and manual transfer switches for smaller applications or budget-conscious installations.
Frequently Asked Questions
What size generator do I need?
It depends on what you want to run. A small residential generator (7-10kW) handles essentials like heating, refrigeration, and sump pumps. Larger homes might need 15-20kW. Commercial installations vary widely based on critical load requirements. We calculate the right size by auditing your equipment and electrical demand.
What's the difference between whole-house and partial generators?
A whole-house generator powers your entire electrical system. A partial (or portable) generator only powers selected circuits — usually essentials like heat, refrigeration, and lights. Whole-house systems are more expensive but provide complete protection. We'll help you choose based on your budget and risk tolerance.
How much does generator installation cost in CT?
Installation costs depend on generator size and whether it's a whole-house or partial system. Transfer switches and connections typically run $1,500–$3,500. Call us at 203-389-5112 for a free site assessment and exact pricing.
Should I choose natural gas or propane?
Natural gas is convenient if you've got it — no fuel delivery needed. Propane gives you independence from utility outages but requires a tank and regular refills. We work with both fuel types and can advise based on your property and priorities.
What permits are required for generator installation?
Generator installations require a permit from your local building department and notification to Eversource. We handle all the paperwork, final inspections, and utility coordination. It's part of the service.
How long does installation take?
Most residential installations take 1-2 days once the generator's delivered and on-site. We handle the electrical connections, transfer switch setup, and all testing. Commercial installations may take longer depending on load requirements and complexity.
