This study analyzes how the Electricity Generating Authority of Thailand (EGAT) rendered environmental conflict ‘governable’ in Mae Moh, a coal-dependent district in Northern Thailand, by applying Michel Foucault’s concept of governmentality. Focusing on the aftermath of major sulfur dioxide pollution incidents in the 1990s, this study explores how EGAT managed the conflict through a combination of technological, institutional, and discursive strategies. These included flue gas desulfurization (FGD) systems, community development funds, CSR projects, pro-coal public relations campaigns, and cultural events like festivals and museum exhibitions. This study finds that such governing techniques not only mitigated public resistance but also fostered a form of subjectivity among local residents that aligned their interests with those of EGAT. By framing environmental risks as technical and controllable, dissent was silenced and community consent was manufactured. The case of Mae Moh demonstrates how state-linked energy institutions govern through various strategies of knowledge production, incentive distribution, and identity construction. It also offers insights into how environmental politics in Southeast Asia are shaped not only by material stakes but also by subtle techniques of rule.
