Descripción general de la generación de interconexiones

As co-participants in the California energy market, certain Interconnection Customers (ICs) may require an interconnection with SDG&E-owned electric transmission facilities in order to transact in the energy marketplace.

Potential ICs should review the following information when applying for electrical interconnection with SDG&E-owned transmission or distribution facilities.

Before a meeting can be established with SDG&E to discuss interconnecting a potential generation project, the IC needs to enter the project into the appropriate generation interconnection process, by identifying whether the project will be interconnecting to the SDG&E Transmission System or Distribution System.

Sistema de transmisión - que conecta a 69kV y por encima

Distribution System - Connecting at 12.47kV and below

The IC is to complete the appropriate Interconnection Request form (IR) and provide the required study deposit for the project to enter the appropriate study queue.

SDG&E provides non-discriminatory access to the grid for all generation projects that request interconnection to the grid under Federal Energy Regulatory Commission (FERC) regulations, the California Independent System Operator (CAISO) Tariff and the SDG&E tariff.

Interconnection Information and Map

SDG&E Transmission System Overview

The San Diego Gas & Electric’s (SDG&E) transmission system (69 kV and above) is under the operational control of the California Independent System Operator (CAISO).  Interconnection of generation facilities to the SDG&E transmission system is subject to the CAISO Federal Energy Regulatory Commission (FERC) approved Generation Interconnection Procedures (GIP) tariff.  Projects proposing to interconnect to the SDG&E transmission system (transmission lines and transmission substations) are studied in a cluster.  In order to evaluate the feasibility of an individual project, as far as transmission capacity is concerned, all projects in that cluster need to be considered to identify the available capacity. 

El sistema de transmisión incluidos en el mapa de este sitio web proporciona la información de transmisión con respecto a la capacidad de salida de la subestación de distribución mediante la indicación de la forma en la subestación de distribución / sistema está integrado en la red de transmisión. Esto proporciona la interconexión de los clientes información sobre la capacidad de flujo de alimentación de la subestación de distribución en el sistema de transmisión.

sistema de transmisión de SDG & E, y en general, cuanto mayor sea CAISO logró red de transporte, se configura como un sistema eléctrico de la red. La naturaleza de un sistema de transmisión de la red es tal que requiere un conjunto específico de estudios para identificar la capacidad disponible en cualquier transmisión o subestaciones dentro de la red. La característica de red del sistema de transmisión sirve para proporcionar flexibilidad, a diferencia de un sistema radial (distribución), en la redistribución el flujo de potencia cuando un elemento de la red está fuera de servicio para mantenimiento o es forzado a salir.

General Notes

  • The website is intended to provide an initial screening of generation interconnection projects. A detailed study is required to confirm all distribution upgrade costs. The interconnection customer should not rely on any cost estimates on this website as they are only intended to provide high level cost information.
  • El mapa de la zona interactiva subestación está destinado a mostrar el área de la subestación general y no un punto específico de la interconexión. El cliente debe cumplir con la interconexión de SDG & E para confirmar el punto de interconexión de subestaciones.
  • The interactive feeder map is not intended for an interconnection customer to identify the exact location for interconnection. The interconnection customer must meet with SDG&E to confirm the interconnection point.
  • Feeder branch routes are not shown on the interactive map as they generally have limited capacity for interconnection. Should a branch be proposed as the point of interconnection it is likely that potentially significant distribution branch upgrades will be required to facilitate the interconnection.
  • The interactive website map is not intended for construction.
  • Interconexión con el sistema de distribución también puede afectar el sistema de transmisión y requerirá un análisis adicional.
  • All interconnection requests shall follow applicable interconnection requirements.
