In this paper we investigate the role of Renewable Energy Sources (RES) on the Italian power exchange. The purpose of this analysis is to assess the impact of electricity generation from RES on the reduction of CO2 emissions and on the value of the power supply. The study is based on hourly zonal micro-data for 2018 from the Italian power market and identifies the amount of avoided carbon emissions related both to crowded-out thermal units and to potential “load-shedding” situations. Finally, the investigation leads to the assessment of both the economic value of RES penetration and to the economic value of the CO2 emissions avoided by renewable power generation. The results show that the annual savings of carbon emissions nationwide amount to nearly 22 Mt CO2 whereas the value of CO2 reduction is estimated at €348 million. The economic savings from large and small-scale wind and solar generation in 2018 account for nearly €19 billion and welfare is increased by 44%, thus confirming the net positive effect arising from RES promotion.

可再生能源对意大利电力市场的碳减排价值

在本文中,我们研究了可再生能源 (RES) 在意大利电力交易中的作用。该分析的目的是评估可再生能源发电对减少CO 2排放和对电力供应价值的影响。该研究基于来自意大利电力市场的 2018 年每小时区域微观数据,并确定了与热机组排挤和潜在“减载”情况相关的避免碳排放量。最后,调查导致对可再生能源渗透的经济价值和可再生能源发电避免的CO 2排放的经济价值进行评估。结果表明,全国每年节约碳排放量近22 MtCO 2,而值CO 2减少估计为3.48亿€。2018 年大型和小型风能和太阳能发电的经济节约近 190 亿欧元,福利增加了 44%,从而证实了可再生能源推广带来的净积极效应。
