The most common schedule risk on development projects in PG&E territory is the electric service timeline. Every project team asks the same question: how long will PG&E take? The answer is "longer than you think," and the reason is that the process has multiple sequential steps, each with its own queue and dependencies, and very few of them can be accelerated.

The Timeline Breakdown

A typical commercial or multifamily project with a straightforward Rule 16 electric service extension:

That is 7 to 15 months for a straightforward project. Add complexity (substation upgrades, capacity constraints, overhead-to-underground conversion, multiple service points) and the timeline stretches to 18 to 36 months.

Where the Delays Happen

Preliminary Engineering Estimate

PG&E's engineering group prepares a cost and scope estimate for the service extension. This step has a queue — your project is in line behind every other project that submitted a request that quarter. During high-development periods, the queue can be 8 to 12 weeks before an engineer is assigned. There is no way to expedite this step. Starting early is the only mitigation.

Detailed Design

After the service agreement is executed, PG&E designs the extension. This includes selecting equipment, sizing transformers, determining switching and protection requirements, and producing construction drawings. For complex projects (multiple transformers, switchgear, underground primary distribution), this takes 12 to 16 weeks. For simple service drops from an existing transformer, it may take only 4 to 6 weeks.

Equipment Procurement

Transformers are the long-lead item. During periods of high demand or supply chain disruption, pad-mounted transformer lead times have reached 26 to 52 weeks. This is the single biggest risk to PG&E timelines and it is largely outside anyone's control. PG&E maintains some stock of standard transformers, but if your project requires a non-standard size or configuration, you are waiting for fabrication.

Inspection Scheduling

After the developer installs the conduit, vaults, and pads, PG&E must inspect the work before proceeding. PG&E's inspection scheduling has its own queue. If the inspector finds deficiencies (wrong conduit size, incorrect bend radius, vault not meeting specification), the developer corrects the work and re-schedules the inspection, adding 2 to 4 weeks each round.

How to Protect Your Schedule

1. Submit the project inquiry the same month you start design. Do not wait for a complete set of plans. PG&E needs a load estimate and a site plan showing the approximate service point locations. This can be prepared from the schematic design.
2. Execute the service agreement as quickly as possible. The advance payment triggers the detailed design. Every week of delay in approving the estimate and executing the agreement is a week added to the end of the timeline.
3. Coordinate with PG&E during the grading and improvement plan design. The civil plans must show the conduit routing, vault locations, and transformer pad details that PG&E specifies. If you design the plans without PG&E input and then PG&E requires changes, you lose time to plan revision.
4. Build the developer-installed work early. Conduit, vaults, and transformer pads should be installed during the site grading and underground utility phase, not during the building construction phase. The earlier the developer work is complete, the earlier PG&E can inspect and schedule cable pull.
5. Track the transformer lead time. Ask PG&E for the expected transformer delivery date and verify it monthly. If the lead time is long, consider whether a temporary service (portable generator or temporary transformer) can allow the project to proceed while waiting for permanent equipment.
6. Have a single point of contact for PG&E coordination. Typically this is the civil engineer or a dedicated utility coordinator. Consistency in communication prevents miscommunication and lost time.

Temporary Power

Construction power (temporary service) is a separate process from permanent service. Temporary service for construction typically requires a 200-amp temporary power panel, a meter base, and a connection to the nearest existing transformer. PG&E can usually provide temporary service in 4 to 8 weeks from application, much faster than permanent service. Budget for it and apply early — you need power for construction equipment, lighting, and testing long before the permanent service is ready.

Multi-Phase Projects

Subdivision and campus projects with multiple phases have additional complexity. PG&E sizes the backbone distribution infrastructure (primary feeders, switchgear, main transformers) for the full buildout, but installs it in phases as each phase of development proceeds. The initial phase typically bears the cost of the backbone infrastructure, with subsequent phases paying only for the incremental extensions to each building or lot.

Coordinate the phasing plan with PG&E early. If Phase 1 needs a specific transformer or switchgear that is not needed until Phase 3 under PG&E's plan, you need to negotiate the sequencing. PG&E will not install Phase 3 equipment during Phase 1 unless the developer pays for it upfront.
