PG&E Underground Electrical Service, Transformers & Trenching

Regent5 coordinates underground electrical service for Northern California estates, including utility routes, transformers, conduit, trenching, vaults, meter locations, switchgear and site construction in collaboration with PG&E or the applicable serving utility.

Start with the Utility Service Route

The route between utility facilities, transformer, meter and main switchgear affects grading, landscape, driveways and construction sequence. Regent5 coordinates the electrical plan with the civil and architectural site design early.

→

Trenching, Conduit and Vault Coordination

Utility-approved conduit, trench depth, sweeps, pull points and vault requirements must be coordinated with site conditions and inspections. Final details follow the serving utility’s engineering package for the property.

→

Transformer Location and Site Impact

Transformer upgrades or new utility equipment can affect setbacks, access, landscaping and visual planning. Regent5 works with the utility and design team so required equipment is accounted for before finished site work.

→

Metering, Switchgear and Electrical Rooms

Large services require coordinated meter locations, service equipment, clearances and distribution space. On complex estates, these are architectural decisions as much as electrical ones.

→

Protect Landscape and Hardscape by Planning Early

Driveways, retaining walls, specimen trees, pools and finished landscape can conflict with utility routes. Early service planning reduces the risk of redesign or excavation after expensive exterior work is complete.

→

Sequence Utility Work with Construction

Utility engineering, owner-side trenching, inspections, transformer work and final energization have dependencies that affect the project schedule. Regent5 coordinates the owner-side scope and tracks utility requirements through the process.

→

Utility Requirements Vary by Jurisdiction

PG&E requirements apply only in PG&E electric territory. Palo Alto and other municipal utilities use their own standards and processes, so Regent5 verifies the applicable serving utility before construction is treated as final.

Coordinated Deliverables for Construction

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.

Low-Voltage Floor Plans

Device locations for network, AV, automation, security, access, controls and related low-voltage systems coordinated against the architectural plan.

Reflected-Ceiling Coordination

Speakers, sensors, cameras, access points, lighting details and other ceiling devices coordinated to preserve clean alignments and architectural intent.

Structured Wiring & Fiber Backbone

Cat6A, fiber, conduit and pathway planning for main houses, guest houses, pool houses, detached offices, gates and outdoor areas, with spare capacity for multi-gigabit networking, PoE devices and future expansion.

Rack Elevations & Equipment Rooms

Rack size, equipment access, ventilation, service clearance, dedicated power, UPS requirements, PoE switch budgets, network topology and heat load planned before millwork and MEP systems are locked.

Conduit, Backboxes & Blocking

Pathways, wall boxes, structural blocking and service access coordinated for displays, lifts, speakers, keypads, shades, security and future expansion.

Lighting Control & Shade Details

Panel locations, circuit interfaces, keypad placement, shade pockets, power/data, blocking and control integration coordinated with lighting and interiors.

Security, Gates & Access Control

Camera sightlines, gate/intercom infrastructure, door-hardware interfaces, lock power, access devices, network requirements and backup-power priorities.

Network & Wi-Fi Architecture

Multi-gigabit wired backbone, access-point locations, outdoor coverage, VLAN and network segmentation, firewall requirements, redundant internet and remote-management needs established before finishes.

Resilient Power & Critical Loads

Network, automation, gates, cameras, alarms and other critical technology loads identified so UPS systems, batteries, generators and load-management strategies support the actual estate priorities.

Commissioning & As-Builts

Final programming, cable and network verification, performance testing, calibration, punch-list completion, current drawings, labeling, system records, configuration backups, staff training and long-term service handoff.

Residential technology preconstruction and low-voltage engineering

Regent5 provides residential technology preconstruction, low-voltage engineering and C7 installation support for custom homes and estates across the San Francisco Bay Area and Northern California, including the Peninsula, San Francisco, South Bay, East Bay, Marin, Wine Country and Carmel/Monterey. Select projects also extend to Santa Barbara, Los Angeles and Orange County, with the same emphasis on coordinated infrastructure, documentation, commissioning and long-term service.

PG&E Underground Service FAQs

When should PG&E underground service coordination begin?

As early as possible in site and electrical design. The service route, meter location, transformer or utility-equipment requirements, trenching, conduit, vaults and main switchgear can affect grading, landscape, hardscape, gates and construction sequencing.

Who determines the final utility service requirements?

The serving utility determines its service requirements and approvals. Regent5 coordinates the project-side electrical design, drawings, load information, routing and field work with the utility, design team and general contractor.

What is included in an underground electrical service route?

Depending on the project, the route can include utility-approved conduit, pull boxes or vaults, transformer interfaces, meter locations, service conductors, main switchgear and the trenching and site restoration needed to connect the property to the utility system.

How is the transformer location coordinated on an estate project?

Transformer placement is coordinated around utility requirements, access, clearances, grading, architecture, landscape, driveways and the electrical service route. The location should be resolved early because it can materially affect the site plan.

Who coordinates trenching, conduit and vaults for underground service?

Responsibilities vary by project and utility requirements. Regent5 can coordinate the electrical scope, conduit pathways, trench requirements and interfaces with excavation, civil, landscape and general-contractor teams so the work is sequenced correctly.

Can Regent5 coordinate high-capacity estate electrical services?

Yes. Regent5 works on large custom-home and estate services where load studies, switchgear, panel architecture, utility coordination, backup power and major electrical loads need to be planned together.

How are meter and switchgear locations selected?

Locations are developed around utility requirements, code, access, conductor routing, architecture, serviceability and the broader electrical distribution plan. They should be coordinated before walls, landscape and exterior finishes make changes difficult.

How can underground utility work avoid damaging finished landscape and hardscape?

The best protection is early coordination. Service routes, sleeves, crossings, vaults and equipment locations should be resolved before final paving, planting, walls and exterior finishes are installed.

How long does utility coordination take?

Timing varies by utility workload, project complexity, design revisions, equipment requirements, permits and construction sequencing. Because several steps depend on outside review, Regent5 recommends starting utility coordination well before the desired energization date.

Can generators, batteries and critical loads be coordinated with the utility service?

Yes. Generator, battery, transfer equipment, surge protection and critical-load planning should be coordinated with the main service and distribution design so resilient power is integrated rather than added as a disconnected system.

Can underground service work be coordinated with gates, pools and detached buildings?

Yes. Estate sites often have multiple underground systems. Coordinating electrical service with gate power, pool equipment, landscape lighting, fiber, low-voltage pathways and detached structures helps reduce conflicts and repeated excavation.

Where does Regent5 provide PG&E underground service coordination?

Regent5 supports complex residential and estate projects across the San Francisco Bay Area and Northern California, including the Peninsula, South Bay, East Bay, Marin, Wine Country and other project locations where the scope is a fit.
