Screening Potential Sites Electronic Decision Tree tool Purpose

Screening Potential Sites: Electronic Decision Tree tool Purpose: To screen sites for suitability for a solar PV or wind energy project. 1

Stakeholders & Targeted Sites Key Stakeholders State & Local Governments and Non-Profit Organizations To screen and prioritize existing sites in communities for their suitability for a renewable energy installation Targeted Sites: Potentially Contaminated or Underutilized Sites Brownfields, Superfund sites, mines, or sites permitted to manage hazardous waste Landfills Renewable Energy Developers To introduce considerations unique to redevelopment of potentially contaminated sites and provide a common framework for interactions with state and local governments during project development phase Clean-up Project Managers To aid clean-up PMs to screen potentially contaminated sites for RE development potential Underutilized rooftops and parking lots Abandoned parcels

Decision Tree Summary - Explores solar (ground mount and/or rooftop) or wind (ground mount) - Can be used for small to large sites to assess potential for distributed, large-scale or utility-scale systems - Walks users through a series of Yes / No / Skip Questions - Supplements questions with additional information, tips and links to relevant resources - Generates reports of the screening results and user comments that can be printed or imported into other documents - Summary Site Screening Report - Data Entry Report - Site Comparison Report
