- Circuit Miles: 128,128 circuit miles of distribution lines.
- Overhead vs. Underground: Approximately 80% of the lines are overhead, while 20% are underground.
- Substations:
- Transmission Substations: 89 transmission substations that facilitate the transformation of high-voltage electricity (from 500 kV to 60 kV) to lower transmission voltages (44 kV to4 kV).
- Distribution Substations: 611 distribution substations and 118 low-voltage distribution substations. Combined, there are 290 transmission and distribution substations that allow for efficient electricity management and delivery.

PG&E interconnects its distribution network to its electricity transmission system at 671 points. The distribution substations serve as operational hubs, outfitted with transformers, voltage regulation equipment, and protective devices. The distribution lines then connect to local transformers to deliver electricity to end-users.

Additionally, PG&E markets electricity to various entities, like municipal utilities, allowing these customers to serve their communities.

Renewable Energy Initiatives
PG&E is also a significant player in Californias transition to renewable energy. The company offers several programs and incentives to promote the adoption of clean energy sources. Their focus includes:

- Solar Programs: Incentives for residential solar installations and partnerships for large solar projects.
- Energy Efficiency Programs: Programs designed to help customers reduce energy consumption and costs.
- Advanced Energy Storage: Investing in battery storage technologies to enhance grid reliability and maximize renewable energy usage.



Natural Gas Utility Operations

PG&E operates an integrated natural gas transportation, storage, and distribution system throughout all or part of 38 California counties. The core components of this system are:

- Pipelines:
- Distribution Pipelines: 40,704 miles that deliver natural gas to customers.
- Backbone and Local Transmission Pipelines: 6,128 miles for the transport of natural gas from production areas to consumers.

- Storage Facilities: PG&E maintains three underground natural gas storage facilities with a combined capacity of approximately 42 billion cubic feet (Bcf).

Service Categorization
The California Public Utilities Commission (CPUC) categorizes PG&E’s natural gas customers into two distinct classes:

1. Core Customers: Primarily residential and smaller commercial customers, making up over 99% of this group who typically choose bundled services. Bundled service includes both the delivery of gas and supply.

Operational Efficiency and Regulatory Compliance
PG&Es operational strategy for natural gas includes regulatory balancing accounts to mitigate the impact of weather variations and consumption fluctuations on long-term operations. The revenue structure is heavily reliant on core customers, accounting for approximately 97% of base revenues, while noncore customers contribute about 3%.

Growth and Strategic Initiatives
To manage future demand and ensure reliability:

- PG&E actively participates in statewide energy planning initiatives, such as the California Gas Report. This document, prepared biennially, forecasts natural gas requirements and supplies for long-term planning.

In summary, PG&E remains committed to providing reliable electricity and natural gas services while also innovating in the renewable sector and enhancing operational efficiency through strategic investments and programs aimed at promoting sustainability and customer satisfaction.
