In his latest column, Stephan Heberer, CEO of Ampacimon, shares his thoughts on recent FERC ANOPR.
The Federal Energy Regulatory Commission (FERC) has issued an Advance Notice of Proposed Rulemaking (ANOPR) to potentially mandate Dynamic Line Ratings (DLR) and enhanced reporting practices on transmission lines. This initiative aims to reduce congestion costs, facilitate new resource interconnection, and improve grid reliability. Industry responses highlight both the benefits and challenges of DLR deployment. Notably, PPL Electric Utilities' implementation of DLR on congested lines in Pennsylvania has projected annual savings of $23 million in congestion costs. While FERC Order 881, effective July 2025, requires Ambient-Adjusted Ratings (AAR), DLR offers more precise, localized ratings by accounting for wind conditions, potentially increasing capacity by 20-40%. The broader adoption of DLR, supported by the WATT Coalition, promises significant cost savings, enhanced reliability, and accelerated integration of renewable energy sources.
