标题： Can the creation of separate bidding zones within countries create imbalances in PV uptake? Evidence from Sweden

摘要： 本文基于合成控制方法，估计了2016年至2022年间瑞典内部电价差异对投资光伏（PV）发电的激励影响。选择瑞典作为研究对象，因为它与意大利一样是欧盟唯一拥有多个竞价区域的国家，并且自2020年以来，北部低电价竞价区域和南部高电价竞价区域之间出现了显著的电价差异。结果表明，位于竞价区域边界以北的市镇的光伏采用率比其南部 counterparts 降低了40.9-48%。根据这些结果，国家内部创建单独的竞价区域可能对光伏发电和其他可再生能源的扩展构成威胁，因为这会降低在电价较低地区投资的激励。 显示英文摘要

摘要： This paper estimates how electricity price divergence within Sweden has affected incentives to invest in photovoltaic (PV) generation between 2016 and 2022 based on a synthetic control approach. Sweden is chosen as the research subject since it is together with Italy the only EU country with multiple bidding zones and is facing dramatic divergence in electricity prices between low-tariff bidding zones in Northern and high-tariff bidding zones in Southern Sweden since 2020. The results indicate that PV uptake in municipalities located north of the bidding zone border is reduced by 40.9-48% compared to their Southern counterparts. Based on these results, the creation of separate bidding zones within countries poses a threat to the expansion of PV generation and other renewables since it disincentivizes investment in areas with low electricity prices.
