We propose a settlement modification: when the zonal day-ahead price exceeds a threshold, non-emitting generation is remunerated at the clearing price minus a fixed CO2-proxy deduction, while all other units continue to receive the uniform price. The mechanism thus reallocates a part of the inframarginal rents to consumers. Using hourly data we estimate static average expenditure reductions of about 8.5 percent in Austria and 4.7 percent in Germany in 2025. We discuss bidding incentives around the threshold, interactions with Contracts for Difference, implementation in coupled bidding zones, and a gas-cost variant for the 2022 energy crisis.","onlinedate":"2026-03-27 14:10:40","lang":"English","publication_series":"","publication_date":"20260327","publication_date_year":"","publication_date_full":true,"publication_num_pages":"25","keywords":"[]","jelcodes":"[]","related_publications":"[]","pdf":444293,"zip":null,"link":"","monthly_report":true,"monthly_report_main":false,"monthly_report_volume":"","monthly_report_pages":"","monthly_report_pages_sort":"0","issue":"725","journal":"WIFO Working Papers","publisher":"","invisible":false,"external":false,"embargo_date":null,"types":[44410],"research_groups":[3655],"collaboration":"","persons":[434906,425699,423889],"persons_data":"[{\"personId\":434906,\"personName\":\"Simon Finster\",\"organisationNames\":[]},{\"personId\":425699,\"personName\":\"Bernhard Kasberger\",\"organisationNames\":[]},{\"personId\":423889,\"personName\":\"Simon R\u00fctten\",\"organisationNames\":[]}]","clients":[],"subclients":[],"partners":[],"topics":[],"host_publication_title":"","host_publication_subtitle":"","place_of_publication":"","host_publication_editors":"[]","type_description":"","output_media":"","chapter":"","article_number":"","scientific_assistance":"[]","scientific_review":"[]","version":"","release_date":null,"expiration_date":null,"surveyor":"","research_assistance":"","edv":"","additional_info_de":"","additional_info_en":""},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.3 (Yoast SEO v27.3) -
