title: High-resolution analysis of power plant land requirements for GODEEEP

description: This dataset contains data associated with Mongird et al. (in prep). Files include output from the following three analyses found in the paper: (1) Projected power plant siting intersections with US Disadvantaged Communities (DACs), important farmland, and natural areas; (2) onshore wind and solar photovoltaic capacity factor availability under 27 different siting restriction cases, and (3) output from an analysis that determines how many DACs are projected to see both fossil fuel generation retirement and new renewable power plant development. Each of the files associated with these components are described below. 

For more detailed information please refer to Mongird et al. (in prep), "High-resolution analysis of power plant land requirements for net zero in the Western United States indicates coordinated land use policies will be essential"

Outputs included in this dataset are associated with two different scenarios. ummaries of each of the two scenarios included are provided below. For additional information, see Ou et al. 2023.

Scenario Descriptions



business-as-usual:



This scenario does not include any long-term federal policies requiring decarbonization.

It does include the US Inflation Reduction Act (IRA) incentives.

It assumes that CCS technologies are available.



net zero:



This scenario includes a clean electricity grid in the U.S. by 2035 and a net-zero economy by 2050.

It does include US IRA incentives.

It assumes that CCS technologies are available.




Data Descriptions

1. Projected power plant siting intersections

Description

These files identify the intersection of projected power plant locations with three types of land: federall identified disadvantaged communities (DACs), important farmland, and land in close proximity to natural areas.
