Transmission Line Ratings Remediation (TLRR) ProgramTransmission Line Ratings Remediation (TLRR) Program
Project Management and Project Controls
Pomona, California

The TLRR program aims to mitigate potential electrical clearance issues on the Clients electrical system in support of NERC reliability. The program’s scope involves remediating more than 11,000 GO95 clearance discrepancies on the existing transmission and sub-transmission lines within the service territory—which had been identified using LiDAR technology and analysis. The program requires the support and coordination of three main groups—bulk transmission, sub-transmission, and distribution—that work together to meet the program’s compliance date of 2030 for all 115kV radial facilities and 2025 for remaining discrepancy remediation. DHS worked closely with multiple internal and external stakeholders, including federal state, and local agencies and was responsible for managing the project stages, such as scoping, environmental review, design, procurement, construction, and close out.
