The implementation of DLR technology, which adjusts transmission ratings based on environmental conditions, is set to significantly boost grid capacity, efficiency, and safety. For California—the world’s fifth-largest economy—this is a monumental step toward achieving grid modernization, enhancing renewable energy integration, and driving cost savings.

When is the Deadline for mandatory DLR implementation?

With the passage of SB1006, utility companies must start evaluating GETs as part of their transmission planning every two years, starting in 2025. This ongoing assessment is expected to push grid operators toward innovation, driving consistent upgrades and optimization in transmission efficiency.

How Will This Affect Utility Companies?

Utility companies across California are now required to implement technologies like DLR, which will help them better utilize existing infrastructure by adjusting line ratings in real-time according to environmental conditions. This new regulatory approach is similar to FERC Order 881, which also mandates the use of Ambient-Adjusted Ratings for improved grid efficiency and reliability. The focus on AAR and DLR helps utilities prevent overloading and take advantage of favorable weather conditions to optimize power flow, all while enhancing renewable energy integration.

With the growing emphasis on grid sustainability, the shift aligns perfectly with broader regulatory trends. The deployment of GETs and technologies like Dynamic Line Rating will help utilities better manage peak loads and environmental challenges, positioning the state for a greener future.

Why This Matters

California’s regulatory push supports smarter energy management, ensuring a more resilient grid capable of meeting modern energy demands. With these mandates, the state is setting an example for other regions to prioritize smarter, data-driven transmission planning. The integration of GETs will result in hundreds of millions of dollars in cost savings annually, more stable grid operations, and significant strides in sustainable energy use.
