Your Building Needs More Power Than It Has

Service Upgrades in Spokane and surrounding areas for properties exceeding current electrical capacity or planning major additions

Thunderbird Power upgrades electrical service for homes and commercial properties in Spokane, Cheney, Deer Park and surrounding areas when existing systems cannot meet increased power demands. You need this service when adding square footage, installing equipment that requires higher amperage, or when your utility meter and main disconnect are undersized for your building's load. A service upgrade replaces the main panel, meter base, and service conductors to deliver the power your property requires without overloading the system.


The process involves coordination with the local utility provider to ensure the new service is properly connected and metered. Thunderbird Power calculates your total load, determines the correct service size, installs the new meter base and main disconnect, and ensures all components meet code requirements. This work is essential for remodels that add multiple circuits, commercial expansions, or homes transitioning to all-electric heating and appliances.


If your project requires more power than your current service provides, contact Thunderbird Power to schedule a load evaluation and discuss the upgrade scope.

How Your Property Functions After the Upgrade

Once the service upgrade is complete, your building can support the full electrical load required by modern equipment and expanded spaces. You no longer face the risk of tripping the main breaker or damaging appliances due to voltage sags. The upgraded service delivers consistent power to all circuits, even when running high-draw devices simultaneously.


Thunderbird Power installs service equipment that passes inspection and meets long-term performance standards. The new meter base, main disconnect, and grounding system are sized to handle your building's current and anticipated needs. This eliminates the bottleneck that prevented you from completing remodels or adding essential equipment.Once the service upgrade is complete, your building can support the full electrical load required by modern equipment and expanded spaces.

The upgrade includes replacement of the weatherhead, service conductors, and any outdated components between the utility connection and your main panel. If the utility requires new infrastructure such as a transformer or service drop, Thunderbird Power coordinates that work to avoid delays. The scope does not include interior wiring unless it is part of the agreed-upon project plan.

Common Questions About Service Upgrades

Here are the questions clients ask when planning a service upgrade in Spokane and the neighboring communities.

When is a service upgrade required instead of just a panel upgrade?

A service upgrade is needed when your utility meter and main disconnect cannot deliver enough amperage to support your building's total load, even with a new panel.

How long does the utility coordination take?

Utility scheduling varies, but most service upgrades in Spokane involve a coordination period of one to three weeks before the utility connects the new service.

Will I need a new meter base?

Yes, upgrading the service typically requires replacing the meter base to accommodate the higher amperage and ensure compatibility with utility equipment.

What happens to my power during the upgrade?

Power is disconnected at the utility level during the installation and reconnected once the new service is installed, inspected, and approved.

Does a service upgrade affect my utility bill?

The upgrade itself does not increase your bill, but if you add high-draw equipment or expand your building, your energy usage will increase accordingly.
