1. Amperage: 100 Amp vs 200 Amp
The single biggest cost driver is the service size you end up with. Many older Fort Worth homes were built with 100-amp service. A like-for-like replacement, swapping a tired 100-amp panel for a new 100-amp panel, is the lighter end of the work because the service capacity is not changing. A 200-amp upgrade is a bigger job: it usually involves a larger panel, heavier service conductors, and more coordination with the utility, all of which add to the cost.
The reason most homeowners still choose the 200-amp upgrade is headroom. If you are replacing the panel anyway and you might add a car charger, a generator, a new HVAC system, or a shop down the road, sizing up once is cheaper than paying for a second upgrade later. We run a load calculation to tell you which size your home actually needs, so you are not paying for capacity you will never use, or boxing yourself in by going too small.
2. Panel Location and Relocation
Where the panel lives matters. A panel in an accessible spot, an exterior wall or an open garage, is faster to work on than one buried in a finished closet or a tight utility space. The cost climbs when the panel needs to be relocated, because relocation means running new conductors to the new position, patching the old location, and sometimes reworking the service entrance. If your project also involves moving the meter, that adds utility coordination on top of the labor.
3. Condition of the Service Entrance
The panel is one piece of the service. The meter base, the weatherhead where the service drop connects, and the grounding and bonding system all have to be sound and up to current code. On an older home, replacing the panel often surfaces a meter base or grounding setup that needs to be brought up to standard at the same time. That is not an upsell; it is the work required to pass inspection. A clean, modern service entrance keeps the cost down, while an aged one adds to it.
4. Permits and Inspection
A panel replacement in Fort Worth is permitted work, and the permit and inspection are part of the cost of doing it correctly. The permit fee is set by the local jurisdiction, and the inspection is what certifies the finished work is safe and code-compliant. Be cautious of any quote that is unusually low because it skips the permit, unpermitted electrical work can surface as a problem when you sell the home and is not worth the short-term savings.
5. Oncor Coordination
Oncor is the utility that owns the service drop and meter in the Fort Worth area. Replacing a panel, and especially upgrading the service size, means the power has to be disconnected at the meter and reconnected once the new panel passes inspection. That disconnect and reconnect is scheduled with Oncor, and the coordination is folded into the project timeline. It is one of the reasons a panel job is not a same-hour swap: the utility's schedule is part of the equation.
6. Rewire Scope
Sometimes the panel is the start of a larger picture. If the branch wiring feeding the panel is old, damaged, or undersized, addressing it is part of making the new panel safe, and a whole-home rewire is a much larger project than a panel swap alone. Most replacements do not require a rewire, but if your home has aged wiring, the estimate should make clear what is panel work and what, if anything, is wiring work, so you can see the two separately.
Ways to Manage the Cost
A few things help. Bundling related electrical work, adding whole-home surge protection or an EV charger circuit while the electrician is already at the panel, is more efficient than separate visits. Financing can spread the cost of a larger upgrade. And sizing the panel correctly the first time avoids paying twice. We walk through all of this on the written estimate.
What Makes Fort Worth Panel Jobs Their Own Thing
Panel replacement is not the same job everywhere, and a few things about the Fort Worth area shape what these projects cost here. The housing stock is a big one: large stretches of the city and the surrounding mid-cities were built decades ago with 100-amp service that was right for that era and is undersized for a modern, all-electric household. That makes the 100-amp-to-200-amp upgrade one of the more common panel jobs in this market, which is a meaningfully bigger scope than a same-size swap.
The local utility setup matters too. Because Oncor owns the meter and service drop across this area, almost every service upgrade has the same disconnect-and-reconnect coordination step built into it, and that step is part of the timeline and the cost no matter which electrician you hire. It is not a place where one contractor can shortcut the other; the utility schedule is the utility schedule.
Demand Is Rising, Which Pushes Upgrades
Two trends are driving more Fort Worth homeowners toward panel upgrades. The first is electric vehicles: a home that adds a Level 2 charger is adding one of the largest continuous loads in the house, and that is frequently the moment an older panel runs out of room. The second is severe weather. North Texas gets hard summer storms and the occasional deep winter freeze, and both push interest in standby generators, which also lean on the panel. When a homeowner is already planning a charger or a generator, folding the panel upgrade into that project is usually the most cost-effective path, because the load calculation, permit, and Oncor coordination are handled once instead of twice.
The takeaway is that panel cost in Fort Worth is rarely just about the panel. It is about the age of the home, the size of the service you need going forward, the utility's role, and what else you are planning to add. An on-site estimate is what turns those variables into a real number.
