Critical Power

When the utility fails, your facility shouldn’t.

Generators, transfer switches, UPS, and the switchgear that binds them — critical power fails at the seams between vendors. Faith Energy engineers the system, installs it, tests it to NFPA 110, and maintains it. One party owns the whole chain from utility to load.

The System

Every layer between the outage and your operations.

Designed as one system, not procured as parts — because the failure mode of backup power is almost never the generator. It’s the seams.

Standby generator systems

Diesel and natural-gas generator sets sized from real load data, not nameplate guesses — siting, sound attenuation, exhaust, and NFPA 110 compliance engineered before the crane shows up.

Automatic transfer switches

Open- and closed-transition ATS, bypass-isolation and service-entrance-rated units — with the NEC 700/701/702 circuit separation that inspectors actually check.

UPS & battery systems

Double-conversion UPS with runtime engineered to the load, lithium and VRLA battery plants, and the maintenance bypass wiring that lets you service them without a shutdown.

Paralleling switchgear

Multi-generator paralleling with load-priority shedding, and utility-paralleling schemes for peak shaving — the controls layer where generator projects most often go wrong.

Emergency & life-safety power

Egress lighting, fire pumps, and healthcare essential electrical systems per NEC 517 — including the selective coordination NEC 700.32 demands and most drawing sets skip.

Energy storage & microgrids

Battery energy storage interconnection, microgrid-ready one-lines, and resilient EV fast-charging sites where storage carries chargers through outages and cuts demand charges every day in between.

Fuel & auxiliary systems

Sub-base and day tanks, fuel polishing, remote annunciation, and permanent docking stations for roll-up generators — the provisions that turn a 3 a.m. outage into a routine connection.

Testing & maintenance

Load bank testing, monthly NFPA 110 exercise programs, transfer-switch service, and preventative maintenance agreements with documentation that survives an audit — or an insurer.

Design & power studies

One-line diagrams, load calculations, short-circuit and coordination studies, and arc flash analysis for emergency systems — produced by the same in-house engineers who design our normal-power work.

The Faith Energy Rule

Backup power fails at the seams. So we removed them.

The typical critical power project splits between a generator distributor, an electrical contractor, and a controls integrator — and when the transfer fails during a storm, each points at the other two. Faith Energy engineers the system, pulls the permits, sets the gear, wires the controls, and runs the load bank. When we hand over the keys, one company has tested the entire chain — and one company answers the phone afterward.

Straight Answers

Critical power questions we answer every week.

What does a critical power contractor actually take responsibility for?
Everything between the utility and the load: generator, fuel, transfer switches, UPS, distribution, controls, code compliance, and the recurring testing that keeps it all certifiable. If a vendor only sells you the generator, you don’t have a critical power contractor — you have a parts supplier.
Generator, UPS, or battery storage — which do I need?
Usually layers of two or three. UPS bridges the seconds, generators carry the hours, and battery storage adds daily economics on top of resilience. The right stack depends on what your downtime actually costs per minute — which is the first number we establish.
How often does a standby generator need to be tested?
NFPA 110 requires monthly exercise under load and weekly inspection, with annual load bank testing where monthly runs can’t hit required load. Healthcare adds NFPA 99 and accreditation requirements. We run the whole program under maintenance agreements with audit-ready records.
Can EV charging sites get backup power?
Yes — and for fleet depots and NEVI-funded corridor sites, they increasingly must. We pair DC fast charging with storage or generation so chargers stay live through outages, and the same asset cuts demand charges the other 99% of the year.

Next Step

Tell us what downtime costs you. We’ll engineer to that number.

Healthcare, data centers, logistics, dealerships, municipal water — if an outage stops you, this is the conversation to have before the season that proves it.
