Transmission Congestion & LMP Spreads indicate the price differences across nodes in the power grid caused by transmission bottlenecks. Locational Marginal Prices (LMPs) vary when transmission lines become constrained, leading to basis differentials between regions and nodes.
Tracking congestion patterns and LMP spreads helps market participants identify basis risk, anticipate congestion charges, and manage procurement strategies. Elevated congestion can signal supply-demand imbalances, infrastructure constraints or extreme weather impacts.
Status: Yellow – Moderate congestion due to transmission bottlenecks in key regions.
Sources: Congestion and LMP spread data from independent system operators and power market price reports.
