Renewable Energy Finance Tracking Initiative (REFTI)


The Renewable Energy Finance Tracking Initiative (REFTI) is a project designed to track renewable energy project financing terms.

Information tracked through the project includes:

  • debt interest rates,
  • equity returns,
  • financial structure applied,
  • Power Purchase Agreement (PPA) duration,
  • and other information.

All information gathered is released on an aggregated basis to ensure confidentiality.

The primary goal of the REFTI project is to help developers, new investors, utilities and regulators understand project financing terms by technology and project size. The intelligence gathered is also intended to inform models developed at the National Renewable Energy Laboratory (NREL) and elsewhere.

In addition to collecting quantitative data on financing terms, NREL also polls industry participants on barriers to financing and development, and the importance and/or effectiveness of policies, renewable energy certificates (RECs), and other support structures. By doing so, NREL hopes to collect the data critical for national labs and policymakers to assess the costs and benefits of various project finance support mechanisms.
