This report identifies technology bias between renewable power plants in technology neutral auctions, caused by different auction design elements. We evaluate our technologies (PV, onshore wind, offshore wind, and biomass) using a quantitative model, with which we determine LCOEs, bid prices, and social values of the technologies are calculated. Based on these calculations, we calculate bias between two technologies, by taking the difference of differences between the bid prices of the auction, and the unit social values of the power plants, which are the total social revenue minus the total social cost in per unit terms.
