PRISMA Open database of region- and technology- specific cost of capital

This open database of region- and technology-specific cost of capital, developed in the PRISMA project, provides region- and technology-specific cost of capital values for renewable energy technologies and other climate-relevant sectors. These data enhance the fidelity and credibility of energy system and IAM analyses, enabling more nuanced assessments of the trade-offs and synergies involved in the low-carbon energy transition.For more information, we refer the reader to the Readme PDF included in this repository. For questions, please contact Bjarne Steffen or Paul Waidelich.

Please note that the database is embargoed until 1 January 2026 and preliminary access can only be granted for project review purposes.
