Energy Systems Analysis Tools

Use these energy systems analysis models and tools developed or supported by NREL to assess, analyze, and optimize renewable energy and energy efficiency technologies for your project.

Many of these tools can be applied on a global, regional, local, or project basis. NREL models and tools include several designed for the consumer or energy professional.

Buildings Industry Transportation Electricity Scenarios (BITES)

See how changes in energy demand and supply by economic sector can impact carbon dioxide emissions.

HOMER

Evaluate design options for both off-grid and grid-connected power systems for remote, stand-alone, and distributed generation applications. HOMER is licensed to and maintained by Homer Energy.

Interactive Mapping Tools

Access RE Atlas, Solar Power Prospector, PVWatts, and other popular tools that dynamically generate maps of renewable energy resources.

REFlex

NREL uses this dispatch model to evaluate renewable generation as a function of system flexibility, and enabling technologies like demand response. Contact Paul Denholm for more information.

Regional Energy Deployment System (ReEDS)

NREL uses this multi-regional, multi-time period, GIS and linear programming model of U.S. electric sector capacity expansion to analyze critical issues in the electric sector.

REopt™

Early screening tool that identifies and prioritizes renewable energy projects using site, resource, cost, incentive, and financial data

Resource Planning Model (RPM)

Capacity expansion modeling to inform utility or regional electric system planning, including for clean energy or carbon mitigation analysis, in the Western or Eastern Interconnections. Contact Trieu Mai for more information.
