标题： District heating systems under high CO2 emission prices: the role of the pass-through from emission cost to electricity prices

摘要： 低二氧化碳价格引发了关于旨在提高二氧化碳排放成本的政治措施的讨论。 这些成本影响了综合区域供热系统运营商（DHSO），这些运营商通常由具有政治影响力的市政当局拥有，并使用各种（高二氧化碳排放强度）的热能发电技术。 我们研究了DHSOs是否有动机在短期内支持提高二氧化碳排放价格的措施。 因此，我们（i）开发了一个简化的分析框架来分析区域供热运营商的最佳决策，并（ii）研究提高排放价格的市场范围影响，特别是排放成本向电价的传递。 使用奥地利和德国共同电力系统的数值模型，我们估计2017年二氧化碳排放价格到电力价格的传递系数在0.69到0.53之间，具体取决于绝对排放价格水平。 我们发现二氧化碳排放成本的传递足够高，以至于至少使用中等效率发电设备的低排放区域供热系统在短期内会从上升的二氧化碳排放价格中受益。 显示英文摘要

摘要： Low CO2 prices have prompted discussion about political measures aimed at increasing the cost of carbon dioxide emissions. These costs affect, inter alia, integrated district heating system operators (DHSO), often owned by municipalities with some political influence, that use a variety of (CO2 emis- sion intense) heat generation technologies. We examine whether DHSOs have an incentive to support measures that increase CO2 emission prices in the short term. Therefore, we (i) develop a simplified analytical framework to analyse optimal decisions of a district heating operator, and (ii) investigate the market-wide effects of increasing emission prices, in particular the pass- through from emission costs to electricity prices. Using a numerical model of the common Austrian and German power system, we estimate a pass-through from CO2 emission prices to power prices between 0.69 and 0.53 as of 2017, depending on the absolute emission price level. We find the CO2 emission cost pass-through to be sufficiently high so that low-emission district heating systems operating at least moderately efficient generation units benefit from rising CO2 emission prices in the short term.
