When properly designed, such policies can ensure cost recovery for producers and investors in the renewable energy sector. Accordingly, this paper seeks to propose a model, based on a game theory approach, to maintain the profit levels of stakeholders. In this context, the leader model incorporates government subsidies, while the follower model represents the profit levels of renewable energy producers. The proposed model aims to identify optimal subsidy policies by considering various factors, thereby sustaining the private sector’s motivation to invest in renewable energy production. The results demonstrate that an increase in government support through different policy interventions leads to higher profit margins for companies. On the other hand, as the number of renewable energy producers (companies) grows, the total government subsidies increase, prompting policymakers to implement measures that enhance market competition and thereby reduce corporate profitability.</p> https://www.journalrmde.com/index.php/jrmde/article/download/95/103
