This document provides recommendations for auction design in Ukraine's renewable energy sector from the AURES II research project. It recommends a simple auction design with one-stage sealed-bid pricing, technology-specific auctions with location-neutrality. Volume setting should have annual revision within 20% and minimum project size thresholds decreasing over time to increase competition. It also proposes "medium-sized auctions" for smaller solar and wind projects of 1-5MW and 1-20MW to introduce more competition.
