The Green Power Market Development Group has developed the following tools to help companies identify, evaluate, and pursue opportunities to buy renewable energy:

Green Power Analysis Tool version 2.0
The Green Power Analysis Tool (GPAT) is a free software tool that allows corporate managers to analyze both the economic and environmental characteristics of one or more renewable energy projects.

Guidelines For Writing a REC Request For Proposal (RFP)
The Guidelines outline elements that a request for proposals (RFP) for renewable energy certificates (RECs) should contain.

Sample Contract for Renewable Energy Certificates
The Sample Contract outlines key elements of a purchase contract for renewable energy certificates. It is similar to the one used by members of the Green Power Market Development Group in their record-setting RECs purchase in the autumn of 2003.

Corporate Case Studies
These case studies highlight green power projects and innovative purchasing strategies implemented by Group partners. Case studies include:

  • DuPont Participation in Emissions Markets
