Screening Tool for Equitable Adoption and Deployment of Solar (STEADy Solar)

The Screening Tool for Equitable Adoption and DeploYment of Solar (STEADy Solar) is a database and mapping tool designed to promoting clean energy investments for low-income communities across the United States. The tool indicates locations that may be eligible for the Investment Tax Credit bonus adders defined in the 2022 Inflation Reduction Act (IRA) and combines this information with demographics, social vulnerability, solar technical potential, solar economics (modeled net present value), and building counts by use-type. It can be used by states, municipalities, community-based organizations, developers, and researchers to identify sites where solar projects may be economical and where federal incentives may be available to support equitable adoption of solar.

Specific values include:
- Areas eligible for the Energy Communities Tax Credit Bonus Program (including brownfield site counts)
- Areas eligible for the Low Income Communities Bonus Credit Program (including Tribal Lands, and covered affordable housing project counts)
- Areas categorized as disadvantaged by Justice40
- Commercial and Residential Solar economics characterized by the Net Present Value and Simple Payback Period
- Total Population, Race, and Ethnicity
- Median Household Income, Poverty rate, Household Tenure
- Social Vulnerability
- Count of buildings, developable rooftop solar capacity (in kWdc) and estimated annual generation potential (in kWh) on four building types: Government General Services, Government Emergency Response, Grade Schools, and Colleges/Universities.

The linked report describes the STEADy dataset metadata and presents high level insights from the data.
The downloadable and formatted excel dataset makes it easy for users to gain insights for their locations.
Supporting .csv and shapefiles provide users with the full data to run their own analyses on equitable solar siting.
