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.
| Name | Size | Type | Resource Description | History |
|---|---|---|---|---|
| National IREZs | 14 KB | Data | This file summarizes 155 IREZs by Hub_Id, Region (transmission plan region), Primary (primary resource type), PV_GW (PV total capacity, GW), Wd_GW (wind total capacity, GW), PV_LCOE_10 (the 10th percentile of LCOE of PV, $/MWh), PV_LOCE_50(the 50th percentile of LCOE of PV, $/MWh), PV_LCOE_avg (the average LCOE of PV, $/MWh), Wd_LCOE_10 (the 10th percentile of LCOE of wind, $/MWh), Wd_LOCE_50(the 50th percentile of LCOE of Wd, $/MWh), Wd_LCOE_avg (the average LCOE of wind, $/MWh), lon (longitude) and lat (latitude). | |
| National IREZs map | 446 KB | Image | 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. | |
| CAISO_Supply_Curve | 72 KB | Data | 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. | |
| ERCOT_Supply_Curve | 159 KB | Data | The table shows the supply curve of each IREZ within the region of ERCOT. Each tab presents an IREZ where the tabs are ranked by the total capacity. | |
