Wind Supply Curves

NREL has developed an interactive map and geospatial data showing wind supply curves, which characterize the quantity, quality, and cost of land-based and offshore wind resources.

Interactive Map

Note: The map is not visible on mobile devices; please view this page on your desktop to access it.

Geospatial Data

Wind supply curve data are provided in .csv format and include latitude, longitude, available area, capacity potential, generation potential, generator capacity factor, and distance to interconnect.

The Open Access supply curve data only applies land area exclusions based on physical constraints (e.g., wetlands, building footprints) or for protected lands.

The Reference Access supply curve data applies a wider range of exclusions and is used by default in NREL’s capacity expansion modeling.

The Limited Access supply curve data applies the most restrictive land area exclusions, capturing potential increased setback requirements and difficulties deploying on federally managed lands.
