In December 2021, the Federal Energy Regulatory Commission (FERC) ushered in a new era of transparency and accuracy in transmission line ratings with FERC Order 881. As transmission providers transition from static/seasonal to ambient-adjusted line ratings, AI-powered tools offer the real-time data processing capabilities they need, resulting in greater grid reliability and lower costs for consumers.
In this webinar, you’ll learn
- Key impacts of FERC Order 881
- Challenges of incorporating real-time temperature data in calculating line ratings
- How AI fills the gap to clear the way for evolution to a smarter, more modern grid
Why FERC Order 881 is a milestone for utilities
FERC Order 881 represents a pivotal shift for utilities, driving improvements in how transmission line ratings are calculated and managed. By mandating the implementation of ambient-adjusted ratings (AARs) and encouraging dynamic line ratings (DLRs), the order aims to enhance grid efficiency, reliability, and capacity utilization. Accurate transmission line ratings are crucial for optimizing energy flow, reducing congestion costs, and supporting the integration of renewable energy sources.
Improved accuracy and transparency
FERC Order 881 requires utilities to update transmission line ratings more frequently—at least hourly—and provide data transparency through accessible databases. This ensures more precise forecasting and near-real-time decision making, which are critical for maintaining grid stability.
Supporting renewable integration
Accurate line ratings allow for the efficient transfer of energy from renewable sources like wind and solar. This reduces the need for curtailments and maximizes the use of existing infrastructure, helping utilities meet sustainability goals and align with broader energy transition initiatives.
Economic benefits
Utilities benefit from reduced congestion costs and better capital investment strategies by avoiding unnecessary infrastructure upgrades. By leveraging advanced technologies like AI for DLR implementation, utilities can unlock additional transmission capacity and achieve annual savings in millions of dollars, as seen in successful pilot programs.
Compliance and modernization
FERC Order 881 accelerates the modernization of grid management systems. Utilities must adopt granular data collection and advanced analytics to comply, fostering innovation and improving overall grid operations.
Implementing FERC Order 881 offers utilities a roadmap to enhance operational flexibility, optimize infrastructure usage, and ensure compliance with evolving energy policies while driving progress toward a more sustainable and efficient energy future.
