This article examines the political dynamics of regulating decarbonised energy such as agrivoltaics and questions the intersectoral logics inherent in this energy. It examines the political dynamics of multi-level and multi-sector regulation of decarbonised energy such as agrivoltaics between the local and national levels and between the agricultural and energy sectors. It hypothesises that the political dynamics of agrivoltaics regulation are first and foremost multi-level: The national framework for agrivoltaics regulation is based on incentive instruments, in which the state attempts to develop a market to achieve its decarbonisation policy objectives via guaranteed feed-in tariffs, and also on an imprecise regulatory framework. At the same time, the regulation of agrivoltaic projects is a prerogative of the local level, paving the way for the development of diversified projects. Agrivoltaics also raises the question of the encounter between two historically well-established areas of public policy: energy decarbonisation policies and agrivoltaics. These strongly mobilise agriculture and farmers and call into question the traditional balances, institutions and sectoral divisions between the energy and agriculture sectors and their players.
