The Suncrest 230kV Loop-In Project is a proposed electrical transmission project by San Diego Gas & Electric (SDG&E). The project would connect an existing 230-kilovolt transmission line to the Suncrest Substation through approximately 14.5 miles of new overhead and underground transmission infrastructure. According to SDG&E, the project is intended to improve electrical reliability and accommodate future energy demand.
The proposed route extends through portions of Alpine, Crest, Harbison Canyon, Cleveland National Forest, the Crestridge Ecological Reserve, and other public and private lands before terminating at the Suncrest Substation.
SDG&E states that California Independent System Operator (CAISO) identified potential transmission constraints and thermal overload concerns in the area. The utility says the project is intended to improve system reliability and support future electrical demand.
Current estimates place the project cost between $500 million and $600 million. The exact cost could change as the project moves through the environmental review and permitting process.
Depending on the final route, nearby property owners could experience impacts related to viewsheds, construction activity, access, easements, or other project-related changes. Residents should review the proposed maps and monitor the environmental review process to determine whether their property may be affected.
The overhead portion of the project would utilize approximately 67 weathered steel transmission poles along roughly 11 miles of the proposed route. Pole heights vary depending on terrain and engineering requirements.
The proposed route passes near sensitive environmental areas, including Cleveland National Forest, the Crestridge Ecological Reserve, protected wildlife habitat, watersheds, and areas of cultural importance to several Kumeyaay tribes. These resources will be evaluated during the environmental review process.
The CPUC is required to consult with affected Native American Tribes and evaluate potential impacts to cultural resources as part of the environmental review process. Several Kumeyaay tribal governments have identified interests within the project area.
SDG&E has stated that this application is not requesting an immediate rate increase. However, because transmission infrastructure becomes part of the utility's regulated assets, project costs may ultimately be recovered from ratepayers through future regulatory proceedings.
Residents can:
Submit public comments to the California Public Utilities Commission (CPUC)
Attend public meetings
Review project documents
Join ECAPS to receive updates and participate in community advocacy efforts.
A public comment allows residents to share concerns that become part of the official record. A formal protest is a legal filing that can provide greater participation rights within the CPUC proceeding. Both serve different purposes during the regulatory process.
Join the East County Alliance for Powerline Safety (ECAPS) to receive project updates, meeting announcements, educational resources, and opportunities to participate in the public process.
Some residents may want a deeper understanding of the project, CPUC process, environmental review, and community advocacy efforts.
