Renewable Energy Supply Curves

NREL develops and disseminates renewable energy supply curves for the research community.

Supply curves characterize the quantity, quality, and cost of renewable resources. Often developed within a scenario framework, they capture a range of drivers that influence renewable energy potential. This foundational information serves as the basis for a variety of analysis and modeling applications.

We currently have supply curve data and interactive maps available for:

A Coordinated Research and Modeling Effort

Annual Technology Baseline (ATB)

Consistent set of technology design and cost data

WIND Toolkit (WTK)

High-resolution wind resource data

National Solar Radiation Database (NSRDB)

High-resolution solar resource data

Renewable Energy Potential Model (reV)

Geospatial assessment of land availability considering the built and natural environment and their intersection with transmission infrastructure and renewable energy technology performance; leverages System Advisor Model for system performance calculation


Production cost model

Regional Energy Deployment System (ReEDS)

Capacity expansion model — United States

Resource Planning Model (RPM)

Capacity expansion model — regional
