Regulatory and policy stability for renewable energy investment: An interdisciplinary analysis of the investment disputes against Spain.

Investment stability in the European renewables energy sector has been affected by regulatory and policy changes, resulting in a series of legal disputes and calls by investors to host countries to maintain regulatory stability. However, understandings of this concept vary, creating uncertainty for key actors, and affecting the overall success of decarbonisation. Therefore, in this paper, Sai Ma, Simon Schaub and Joan Enguer analyse the concept of ‘stability’ using renewable energy regulatory reforms in Spain as a case study, arguing that fostering a common understanding of the concept can improve certainty and predictability for both host countries and investors, supporting renewables energy expansion and decarbonisation.
