This chapter provides an overview of the legal and regulatory framework of renewable energy projects in East Africa and examines the role of arbitration and other dispute resolution mechanisms in this rapidly evolving sector. It highlights key factors of disputes, including construction delays, regulatory changes, and tariff adjustments, and reviews notable case studies from across the region. Drawing on comparative insights from European renewable energy disputes, the chapter recommends that regulatory stability, proactive stakeholder engagement, and robust, locally accessible dispute resolution mechanisms are essential for sustainable energy growth and enhanced investor confidence.
