PG&E Service Application & Utility Coordination for Custom Homes & Estates

Regent5 supports architects, general contractors, owner’s representatives and homeowners with utility-service planning, load studies, one-lines, site plans, PG&E applications, transformer coordination and service-route development for complex Northern California residential projects. Final utility capacity, design requirements and schedules remain controlled by the serving utility.

Load Studies Establish the Utility Request

The service request should reflect actual calculated loads, including electrification, EV charging, HVAC, pools, exterior heating, lighting, batteries, generators and other estate systems. Regent5 develops the customer-side load case so the utility review starts from a defensible electrical design.

One-Lines, Site Plans and Service Information

Utility coordination can require electrical one-lines, meter and switchgear information, site plans, proposed service routes and equipment locations. Regent5 organizes and updates that project information as the electrical design and site plan develop.

→

PG&E Application and Engineering Coordination

Regent5 can coordinate customer-side service application information and respond to engineering requests through the project. PG&E retains authority over utility-side engineering, available capacity, approvals and construction requirements.

→

Transformer and Service-Route Planning

Transformer placement, underground routing, metering and service equipment can affect architecture, grading, civil work and landscaping. These decisions are coordinated early so utility requirements can be reflected in the site and building design.

A Utility Coordination Resource for Architects and GCs

Regent5 translates utility requirements into project decisions: equipment space, route assumptions, owner-side trenching, switchgear, schedule dependencies and design changes. This keeps the architect, builder and owner’s representative aligned as the utility process evolves.

→

Plan for Utility Lead Times Without Promising Them

Engineering queues, transformer work and utility construction can affect project schedules. Regent5 tracks actual milestones and coordinates owner-side work, but does not promise generic utility completion dates or capacity decisions outside the project team’s control.

Verify the Serving Utility First

This page applies to PG&E electric territory. Properties in other utility territories follow different processes—for example, Palo Alto is served by City of Palo Alto Utilities. Regent5 verifies the serving utility and coordinates the correct application path for the property.

PG&E Service Application & Utility Coordination Scope

The exact drawing and coordination package depends on project scope, but these are recurring interfaces luxury residential teams need resolved before drywall and finish work.

Load Study & Service Sizing

Calculated property loads organized around electrification, HVAC, EV charging, pools, heating and resilient-power systems.

Electrical One-Lines

Proposed service, metering, switchgear and distribution architecture documented for utility and project-team review.

Site & Service Route Planning

Meter, transformer and service-route assumptions coordinated with architecture, civil work, grading and landscaping.

PG&E Application Coordination

Customer-side application information, supporting documentation and engineering responses coordinated through the project.

Transformer Coordination

Proposed load, equipment locations and site constraints coordinated with utility-side transformer requirements as they are issued.

Meter & Switchgear Coordination

Metering, switchgear, CT provisions and equipment-space requirements reflected in the customer-side electrical design.

Applicant Design Coordination

Where PG&E’s Applicant Design option applies, Regent5 coordinates project information with the PG&E-qualified Applicant Designer without claiming that utility-design role itself.

Architect / GC Coordination

Utility requirements translated into site, equipment-room, trenching, schedule and electrical decisions for the broader construction team.

Owner-Side Trenching & Infrastructure

Customer-side conduit, trenching, equipment pads and service infrastructure coordinated to the approved utility design.

Schedule & Milestone Tracking

Actual application, engineering and construction milestones communicated to the project team without inventing utility completion dates.

PG&E Service Application & Utility Coordination FAQs

What information is needed before starting a PG&E service application?

The project typically needs a clear scope, load information, existing and proposed service conditions, site information and enough electrical design detail to support the utility review. Regent5 organizes the customer-side information and coordinates the application around the project team and serving utility requirements.

When should PG&E coordination begin on a custom home or major renovation?

Ideally during design development, before service size, meter and switchgear locations, transformer assumptions, trench routes and major electrical loads are fixed. Utility decisions can affect architecture, site work, permitting and the construction schedule.

Can Regent5 submit and coordinate a PG&E service application through Your Projects?

Regent5 can coordinate the customer-side service application and project information through PG&E’s current project process where appropriate, including load information, site documentation and responses needed from the electrical and construction team. Utility engineering decisions and approvals remain with PG&E.

Why are load calculations and single-line diagrams important to utility coordination?

They define the electrical demand and proposed distribution architecture so the utility and project team can evaluate service capacity, metering, equipment and connection requirements. They also help prevent service assumptions from being made independently of the actual property loads.

How are transformer needs and service routes identified?

Regent5 coordinates the proposed load, meter and switchgear location, site conditions and preferred service route, then incorporates the serving utility’s engineering requirements. The final utility-side transformer and routing requirements are determined through the utility review.

What does PG&E mean by the Applicant Design program?

PG&E’s Applicant Design program is a specific utility option in which qualifying utility-distribution design work is performed by a PG&E-qualified Applicant Designer. Regent5’s role on this page is service-application and project coordination; it is not a claim that Regent5 is itself the PG&E-qualified Applicant Designer.

Can Regent5 coordinate a project that uses a PG&E-qualified Applicant Designer?

Yes. When that utility option applies, Regent5 can coordinate the customer-side electrical scope, load information, site requirements and construction interfaces with the project team and the qualified Applicant Designer without representing that utility-design role as Regent5’s own.

Do you coordinate directly with architects, builders and owner’s representatives during the utility process?

Yes. Utility service can affect site planning, equipment rooms, exterior elevations, trenches, switchgear, schedule and budget. Regent5 keeps those interfaces coordinated with the architect, builder, owner’s representative and other consultants so utility decisions are reflected in the project documents.

Can Regent5 handle utility coordination if another electrician is performing the field installation?

Yes. Regent5 can provide the engineering and utility-coordination layer while working with the property’s existing electrician, general contractor and other vendors, or Regent5 can deliver the electrical scope as a design-build project when that is the preferred delivery model.

How should a project team plan around PG&E engineering lead times?

Start early and avoid building the construction schedule around an assumed utility completion date. The engineering queue and required utility-side work vary by project, so Regent5 uses actual utility milestones to update the project team rather than promising a generic timeline.

Are Palo Alto projects coordinated with PG&E?

No. Palo Alto is served by City of Palo Alto Utilities, so electrical-service planning follows CPAU requirements rather than PG&E electric requirements. Regent5 verifies the serving utility and coordinates the correct process for the property.

How does utility coordination relate to a 320A, 400A, 600A, 800A or 1000A+ service upgrade?

The requested service size is only one part of the project. The serving utility must also evaluate available capacity, metering, routing, transformer conditions and other utility-side requirements. Regent5 coordinates that process with the customer-side electrical design so the proposed service is grounded in both the load study and the utility response.
