Meaning
Geographic disparities in supply and demand generate price differences for identical commodities at different points of delivery. Locational basis spread is the price differential between a benchmark hub and a specific physical delivery location. This spread reflects the cost of transportation, pipeline capacity constraints, and local market conditions between the two points.
Geographic Variance
Energy supply contracts often price natural gas or electricity at a national benchmark while requiring physical delivery to a specific regional terminal. The locational basis spread is added to or subtracted from the benchmark price to determine the actual landed cost of the energy. This differential can fluctuate rapidly during periods of extreme weather or infrastructure outages.
Infrastructure Constraint
Limited pipeline or transmission line capacity prevents the free flow of energy from low-cost production zones to high-demand urban centers. When transmission bottlenecks occur, the local price at the destination rises while the price at the production hub falls, widening the locational basis spread. This scenario penalizes off-takers who have not secured firm transport rights.
Risk Mitigation
Companies hedge this geographic price exposure using financial transmission rights or basis swaps. These financial contracts offset the cost of price divergences. This locks in the delivery margin.
