200-Amp Electrical Service Upgrade in Las Vegas & Henderson
When your home needs more total power — not just a new breaker panel — a 200-amp service upgrade increases capacity from the utility meter through your main disconnect. Penny Electric handles heavy-ups for Las Vegas homes adding central AC, EV charging, additions, tankless water heaters, and solar. NV Energy coordination included.
When Does Your Home Need a 200-Amp Service Upgrade?
A service upgrade — sometimes called a heavy-up — increases the total amperage your home can draw from the utility, not just the breaker panel itself. Many Las Vegas homes built with 100-amp or 125-amp service cannot safely support modern loads: two AC units, a Level 2 EV charger, a tankless water heater, and a kitchen remodel running simultaneously.
Clark County building departments and NV Energy often require a service upgrade before approving solar interconnection, large tankless water heaters, or additions over a certain square footage. If your main breaker is already near its limit and you are planning any of these projects, upgrading to 200-amp service first avoids failed inspections and costly rework. Homes in older Las Vegas tracts near Maryland Parkway, downtown Henderson, and early Green Valley builds frequently still have 100-amp meter bases that must be replaced as part of the heavy-up.
A 200-amp service upgrade is broader than swapping a breaker panel: it typically includes a new meter base, service entrance conductors, main disconnect, grounding updates, and coordination with NV Energy to reconnect service at the higher amperage. Penny Electric handles the electrical scope, permits, and inspection — and walks you through utility scheduling so you know when power will be interrupted.
This work is part of our complete electrical panel services for Las Vegas and Henderson homes and businesses — licensed, permitted, and code-compliant.
Signs You Need More Service Capacity
100-amp service with modern loads
Older Las Vegas homes on 100-amp service often cannot support EV charging, dual AC, and kitchen upgrades without dimming lights or tripping the main breaker when loads stack up.
Major addition or ADU
New square footage in Henderson or Las Vegas adds circuits and demand that exceed existing service capacity — inspectors will require adequate service before final approval.
Utility or inspector requires upgrade
Solar, battery, Span panel, or large appliance installs may trigger a required service increase before NV Energy or the city will sign off.
Main breaker maxed with no room to grow
When the main disconnect is at its limit and tandem breakers fill every slot, a panel swap alone cannot add the capacity you need — the service entrance must increase.
Adding serious load? We'll calculate service size and quote upfront.
What a 200-Amp Service Upgrade Includes
- Load calculation and service size recommendation
- Coordination with utility for meter and service increase
- New main disconnect and service entrance equipment
- Panel upgrade or replacement when required
- Permit filing and inspection coordination
- Code-compliant grounding and bonding updates
A service upgrade addresses total home capacity from the meter inward — distinct from a panel upgrade that increases breaker capacity without changing service amperage. We also install Span smart panels, battery backup, and EV chargers that often trigger the need for a heavy-up.

200-amp service upgrade cost in Las Vegas varies widely — typically from the mid thousands to $10,000+ depending on whether the meter base, service mast, underground lateral, or panel all need replacement, and how much stucco or landscaping must be disturbed. NV Energy fees and utility reconnect scheduling are separate from our electrical quote but we help you understand the full timeline. Homes with overhead service vs. underground feed have different scope and price profiles.

200-Amp Service Upgrade FAQ
What is a 200-amp service upgrade?
It increases your home's total electrical service capacity — typically from 100-amp to 200-amp — including the main disconnect, service entrance conductors, meter base, and utility meter coordination. It is broader than swapping a breaker panel alone.
Do I need a 200-amp upgrade or just a panel upgrade?
A panel upgrade increases breaker capacity inside the existing service size. A service upgrade increases total amperage from the utility — needed when the entire home outgrows 100-amp service. We assess and recommend honestly based on load calculation and your planned additions.
Why do Las Vegas homes need 200-amp service?
Dual AC, EV charging, tankless water heaters, pool equipment, and additions push demand beyond what 100-amp service was designed for — especially in older valley homes built before modern appliance loads. Summer AC plus EV overnight charging is a common combination that exceeds 100-amp capacity.
Do you coordinate with the utility company?
Yes — we handle the electrical scope and coordinate with NV Energy for the meter and service increase as part of the project. Utility reconnect timing affects when your power is restored after the heavy-up.
How long does a service upgrade take?
Most on-site electrical work completes in one to two days. Overall project timing includes permit approval, NV Energy scheduling, and final inspection — often two to four weeks from contract to completion depending on utility backlog.
How much does a 200-amp service upgrade cost in Las Vegas?
Most residential 200-amp heavy-ups in Las Vegas and Henderson range from roughly $4,000 to $10,000+ depending on overhead vs. underground service, meter base condition, panel replacement needs, and stucco repair. NV Energy charges separate fees. We quote itemized pricing after site assessment — the only accurate method.
Will I lose power during a service upgrade?
Yes — power must be disconnected for the meter and service change. The outage is typically several hours on the day of utility coordination. We schedule the window in advance and restore circuits once the new service is energized and tested.
Is a 200-amp upgrade required for solar or EV charging?
Not always — but NV Energy and inspectors often require it when load calculations show 100-amp service cannot support the new load plus existing home demand. We run the calculation before you commit to solar, battery, or EV equipment.
