Company — EST. 2020, Roseville CA

Show up. Build it right.
Stand behind it.

That was the founding principle in 2020, and it hasn't needed an update since. Reliability is the product — the generators, chargers, and fiber are how we deliver it.

The story

Born on carrier sites. Built for everything after.

JMES started in 2020 as a telecom contracting operation, cutting its teeth on the least forgiving work in the industry: generator installations for carrier sites that cannot go dark. Sites where every ground gets labeled, every load test gets documented, and every closeout package gets audited.

Founder Jordan Moore brought over 20 years of hands-on field experience to that work — and a simple observation: most contractors treat documentation and follow-through as paperwork. In critical infrastructure, they are the product.

Today JMES Infrastructure Group carries that standard across backup power, EV charging, and fiber construction throughout Northern California. The dual B + C-10 license means one contractor can own the whole scope — pad, trench, panel, and termination — and one name stands behind all of it.

"If it leaves our hands, it passes inspection. Every time."

Why we exist

Mission & vision

Mission
Build what the grid depends on

Power, charging, and network infrastructure for California — installed right, energized on time, documented completely.

Vision
NorCal's first call

The contractor carriers, builders, and owners call first for backup power, EV charging, and telecom infrastructure — and never have to chase.

Tagline
Built for the field.

Not a slogan — a filter. If a decision doesn't hold up on a job site at 6 a.m., it doesn't hold up.

Core values

The rules we don't bend

Built right

No shortcuts on materials, code, or craftsmanship. If it leaves our hands it passes inspection — every time.

On site when we say we will be. No excuses, no ghosting. Reliability is the product.

Own it

When something goes wrong we say so, fix it, and move on. We own our work completely.

Build forward

EV infrastructure, IBS, backup power, grid-edge — we move toward what's next, not what's comfortable.
