Indigenous Peoples, Energy, and Environmental Justice: The Pangue/Ralco Hydroelectric Project in Chile’s Alto BíoBío

The Pangue/Ralco hydroelectric projects in Chile's Alto BíoBío caused severe disruptions to the Mapuche/Pehuenche people's semi-nomadic lifestyle and cultural ecosystem. The project sponsor, Endesa, and the Chilean government are accused of violating indigenous land rights and environmental laws, while the IFC faced criticism for failing to oversee social and environmental standards. After a decade of struggle and legal battles in Chilean courts and before the Inter-American Human Rights Commission (IACHR), a 'friendly settlement' was reached in 2003, providing reparations to affected families and commitments from the Chilean government to strengthen indigenous rights and environmental protections in the region.

• The construction of the Ralco dam caused irreversible damage to the Mapuche/Pehuenche people by destroying their cultural ecosystem, flooding ceremonial spaces (Nguillatun fields) and cemeteries, and disrupting their semi-nomadic lifestyle of moving between the Andes in summer and low-lands in winter.
• The project sponsor, Endesa, employed a strategy of deception and coercion to divide the Pehuenche communities and secure land rights, using rumors, false information, threats, and the distribution of alcohol.
• The International Finance Corporation (IFC) failed to supervise the Pangue dam project according to World Bank standards. An independent review known as the 'Hair Report' documented gross non-compliance with environmental and social standards and a failure by IFC management to disclose material information to its Board of Directors.
• The Chilean government intervened in the National Corporation for Indigenous Development (CONADI) to ensure the approval of land exchange agreements for the Ralco project, which included removing the head of CONADI and other opposing council members.
• The Ralco project was found to be illegal on multiple counts, including violations of the 1993 Indigenous Peoples Law, the 1994 Environmental Framework Law, the water law, the electricity law, the Chilean constitution, and the Inter-American Convention of Human Rights.
• A 'friendly settlement' reached in October 2003 through the IACHR provided affected Pehuenche families with land of good quality, technical agricultural support, scholarships, and monetary compensation of approximately US$300,000 per family.
• As part of the 2003 settlement, the Chilean government committed to ratifying the International Labour Organisation (ILO) Convention 169, reforming the constitution to recognize indigenous peoples, and guaranteeing that no other hydroelectric projects would be built in the Upper BíoBío region.
