Whether you're adding an ADU, finishing a major renovation, or your existing service just can't keep up anymore, a new electrical service brings your home's main connection up to modern capacity. At Site Electric Services, we install new service entrances, meter bases, and panel upgrades coordinated directly with PG&E.
We proudly serve Vallejo, Benicia, Napa, Fairfield, Concord, Martinez, and surrounding areas with expert-level service that's built on experience, honesty, and an unmatched reputation for quality.
Signs include frequent breaker trips, an older fuse-based panel, adding a major appliance or EV charger without capacity to spare, or a panel that's physically damaged or corroded. An electrician can confirm with a quick assessment and load calculation.
A new electrical service replaces the connection point between the utility's power line and your home's main panel — including the meter base, service entrance conductors, and often the panel itself. This is typically required when upgrading from 100A to 200A service, adding a detached ADU with its own service, or replacing a service that's been damaged or condemned.
Because this work involves the utility connection, it requires coordination with PG&E for a temporary disconnect and reconnect, along with a permit and inspection before power is restored.
Our focus is on residential electrical work done right the first time, not rushed patch jobs. We bring an unmatched level of care and expertise to each job, with a reputation built on referrals, repeat business, and integrity.
We start by understanding your project — whether it's an upgrade, an ADU, or new construction — and answering your questions up front.
Our electricians assess your current service, panel location, and PG&E connection to plan the new service.
We explain your options in plain language and provide an accurate, upfront estimate before any work begins.
We coordinate the PG&E disconnect, complete the installation, and schedule inspection so power is restored as quickly as possible.
An aging or undersized electrical service doesn't usually fail gracefully — it fails at the worst time, often after a PG&E flag or a failed inspection holds up a sale or renovation. Planning ahead avoids the scramble.
We proudly provide new electrical service installation throughout Vallejo, Benicia, Napa, Fairfield, Martinez, Concord, American Canyon, Vacaville, and Walnut Creek.
Whether you own a historic home in Benicia, a mid-century house in Vallejo, or a new construction in Napa, we have the knowledge and tools to get your new service installed safely and up to code.

A service upgrade typically means replacing an undersized or outdated panel with a higher-capacity one using the existing service entrance. A full new service installation replaces the entire path from the utility connection through the meter into a new panel — needed when the existing infrastructure can't support the upgrade.
Most installations take one to two days. Power is off for a portion of that time — often just a few hours — while the old service is disconnected and the new one is connected and inspected.
Most modern homes are comfortable at 200A, which covers central AC, an EV charger, and most electric appliances. Larger homes, all-electric houses, or homes planning multiple big additions (pool, generator, EV charging) sometimes call for 400A.
A load calculation compares what your home actually draws — and plans to draw — against your panel's rated capacity, and is one way to check. If the calculation doesn't match real-world usage, a load study using recording power meters can confirm whether the panel is actually overloaded. If you're tripping breakers regularly, or want to add a major load and there's no room left, that's usually the sign it's time to look at an upgrade.
A like-for-like replacement (same amperage, no upgrade) on an overhead service typically runs around $4,500, which includes the permit and PG&E application. A like-for-like replacement on an underground service is more involved and usually runs closer to $5,500. Upgrading to higher amperage costs more and requires PG&E engineering approval in advance — for underground services, an upgrade often means trenching, which increases the cost significantly. These are handled case by case, but underground services needing an upgrade typically range from $10,000 to $20,000 or more.
