Description
The National Transmission Planning Study (NTP Study) analyzed the transformation needed to ensure the U.S. transmission system continues to reliably meet electricity demand as the power sector evolves. The study linked several long- and short-term power systems models to test numerous interregional and regional transmission buildout scenarios. The results included in this dataset are from the long-term capacity expansion modeling, completed with NREL's ReEDS model. This includes nearly 100 future transmission scenarios with a wide range of economic, reliability, and resilience conditions. The dataset includes all the results visualized in the Tableau Public site, as linked below.

| Name | Format | Description | Link |
|---|---|---|---|
| National Annual System Cost.csv | CSV | National Annual System Cost ($/MWh). Annual system cost is given by the sum of undiscounted annualized electricity system expenditures (fixed and operating) and tax credits, divided by annual end-use electricity demand (excluding induced demand from storage charging, H2 production for use in H2-CTs, and transmission losses). Regional level results are not available. | Open resource |
| Annual End-use Electricity Demand.csv | CSV | Annual end-use electricity demand (TWh). Total generation is greater than end-use demand because of transmission and distribution losses, storage losses, and generation for direct air capture or hydrogen production via electrolyzers. | Open resource |
| Capacity.csv | CSV | Capacity (GW) by technology, year, spatial aggregation and region. | Open resource |
| Emissions.csv | CSV | Emissions (million metric tonnes) shown are direct combustion emissions by pollutant, year, spatial aggregation and region. | Open resource |
| Generation.csv | CSV | Generation (TWh) by technology, year, spatial aggregation and region. | Open resource |
| Long-Term Modeling Results by National Transmission Planning Study.twbx | Unknown | Tableau Packaged Workbook used in the Tableau Public visualizations. | Open resource |
| National Net Present Value.csv | CSV | National net present value (NPV) (billion $). NPV costs are for all expenditures from 2022 to 2050 using a 1.7% societal real discount rate. Regional level results are not available. | Open resource |
| Peak Coincident End-use Electricity Demand.csv | CSV | Peak coincident end-use electricity demand (GW). Does not include demand for direct air capture or hydrogen production via electrolyzers. | Open resource |
| Interregional Transmission.csv | CSV | Interregional transmission (GW) by technology, year, spatial aggregation and region. National data reflect the interregional transmission between the 11 transmission planning regions. | Open resource |
| Transmission Map.csv | CSV | Data used in the maps in the Tableau Public visualization. Transmission deployed (GW) between ReEDS regions by technology and year. Data is broken into existing transmission (pre-2020), new transmission (post-2020) and total transmission (existing + new). | Open resource |
| Total Transmission .csv | CSV | Total transmission (TW-mi) by technology, year, spatial aggregation and region. | Open resource |
