200 Amp Service Upgrade Cost in Fresno (2026 Guide)
At Reliant Electrical and Automation Inc., we install and upgrade electrical services across Fresno, Clovis, and Madera every week. One of the most common questions we get is: how much does it cost to upgrade to a 200 amp service?
In this guide, we break down real 2026 pricing, what affects the cost, and what to expect from start to finish.
TL;DR: A 200 amp electrical service upgrade in Fresno typically costs between $3,500 and $8,500. The final price depends on panel location, PG&E requirements, trenching, and whether additional subpanels or rewiring are needed.
What Is a 200 Amp Service Upgrade?
A 200 amp service upgrade increases your home’s electrical capacity by replacing your existing service equipment, typically including:
- Meter-main combo or panel upgrade
- New main breaker (200A)
- Service entrance conductors
- Grounding and bonding updates
- Utility coordination with PG&E
Most older homes in Fresno still run on 100 amp service, which is no longer enough for modern loads.
Average Cost in Fresno (Real 2026 Pricing)
- Basic panel swap (same location): $3,500 – $5,000
- Meter-main combo upgrade: $4,500 – $6,500

What Drives the Price
Panel Location
- Same location = cheaper
- Moving the panel adds labor and conduit
Overhead vs Underground Service
- Overhead is typically simpler
- Underground often requires trenching and conduit runs
Meter-Main vs Subpanel Layout
- Meter-main combos are standard in Fresno
- Additional subpanels increase cost but improve layout
Trenching / Drywall / Finish Work
- Exterior conduit runs are cheaper
- Crawl space and attic access matter significantly
PG&E Requirements
- Clearances
- Meter height
- Service mast specs
- Inspection coordination
When You NEED an Upgrade
You should strongly consider upgrading to 200A if you’re adding:
- EV charger (Level 2 or higher)
- Battery backup system
- Solar system expansion
- Heat pump HVAC or water heater
- Hot tub or large loads
Or if you currently have:
- Zinsco or Federal Pacific panel
- Frequently tripping breakers
- No space for new circuits
PG&E Rules That Affect Cost
PG&E often requires:
- Meter relocation to exterior
- Minimum clearances from windows and doors
- Proper service mast height and attachment
- Inspection before reconnect
Delays or corrections here are one of the biggest cost variables.
Typical Timeline
- Planning & estimate: 1–3 days
- Permits & utility coordination: 1–3 weeks
- Installation: 1–2 days
- Inspection & reconnect: 1–5 days
Most projects complete in 2–4 weeks total

100A vs 200A vs 400A – What Should You Choose?
- 100A: Only for very small or older homes
- 200A: Standard for most homes (recommended)
- 400A: Large homes or heavy electrical loads
If you’re planning EV, battery backup, or electrification, 200A is the minimum recommended.
