Interregional Renewable Energy Zones

Publicly accessible License 

Interregional Renewable Energy Zones (IREZs) are a component of the National Transmission Planning Study (NTPS), which analyzes strategies for building out transmission infrastructure to support decarbonizing the electricity sector by 2035. In particular, IREZs envision long-distance transmission corridors for moving large amounts of low-cost renewable energy. An IREZ is a transmission collection point that is easily accessible to a very high volume of low-cost developable wind and solar energy potential. This dataset includes 155 IREZs identified across the continental United States where each IREZ is characterized by its primary and secondary resource.

The table shows the supply curve of each IREZ within the region of CAISO. Each tab presents an IREZ where the tabs are ranked by the total capacity.

This map shows the spatial distribution of wind and solar IREZs overlaid with the transmission plan region and the states boundary. IREZs within a region are in alphabetical order representing the order of total capacity of the primary and secondary resource. A letter within a region corresponds to the tab name of a region’s supply curve table.
