Puesco-Momolluco complex and Tolten Watershed hydropower plans, Chile

"Los ríos nos unen" (rivers unite us), say basin-wide opposition to "sacrifice watersheds"; read about this RoR project included in the government study aiming at massive exploitation of major river basins in the country


Description:

El Proyecto Hidroeléctrico Puesco – Momolluco”, pretendía localizarse en las comunas de Curarrehue y Pucón, aproximadamente a 58 km al suroriente de la ciudad de Pucón y unos 20 km al sur de la ciudad de Curarrehue con una  construcción y operación de dos centrales hidroeléctricas de pasada, denominadas Central Hidroeléctrica Puesco (CH Puesco) y Central Hidroeléctrica Momolluco (CH Momolluco). La CH Puesco pretendían instalarla en la ribera izquierda del río del mismo nombre para generar una potencia de aproximadamente 19,8 MW utilizando para ello un caudal máximo de 7,4 m3/s del río Puesco, mientras que la CH Momolluco en la ribera oriente del río homónimo para producir una potencia de aproximadamente 19,9 MW con  un caudal máximo de 12,2 m3/s obtenidos del río Momolluco. La operación de ambas centrales buscaba generar aproximadamente 175,2 GWh al año. Asimismo, para inyectar la energía generada al Sistema Interconectado Central (SIC) se proyectaba la construcción de dos subestaciones eléctricas (S/E Puesco y S/E Momolluco), una Línea de Transmisión (LTE) de 66 kV, de aproximadamente 52,5 km, y una Línea de Conexión de tipo Tap-Off de 1,53 km.

Project Details and Actors
Project details:

El Proyecto consiste en la construcción y operación de 2 centrales hidroeléctricas de pasada, denominadas Central Hidroeléctrica Puesco (CH Puesco) y Central Hidroeléctrica Momolluco (CH Momolluco). Las obras de generación de la CH Puesco se ubicarán en la ribera izquierda del Río Puesco y tendrán una potencia de aproximadamente 19,8 MW, mientras que las obras de generación de la CH Momolluco se ubicarán en la ribera oriente del río Momolluco y tendrán una potencia de aproximadamente 19,9 MW, por lo cual ambas califican como un Medio de Generación No Convencional (MGNC). La operación de ambas centrales pretende generar aproximadamente 175,2 GWh al año. Para inyectar la energía generada al Sistema Interconectado Central (SIC) se requiere construir obras de transmisión, consistentes en dos subestaciones eléctricas (Subestación Puesco y Subestación Momolluco), una Línea de Transmisión de aproximadamente 52,5 km, y una Línea de Conexión de tipo Tap-Off.

Impacts of the project
Environmental ImpactsVisible: Biodiversity loss (wildlife, agro-diversity), Food insecurity (crop damage), Global warming, Loss of landscape/aesthetic degradation, Deforestation and loss of vegetation cover, Large-scale disturbance of hydro and geological systems, Reduced ecological / hydrological connectivity
Potential: Floods (river, coastal, mudflow), Noise pollution, Waste overflow, Surface water pollution / Decreasing water (physico-chemical, biological) quality, Groundwater pollution or depletion
Health ImpactsPotential: Accidents, Mental problems including stress, depression and suicide, Violence related health impacts (homicides, rape, etc..), Health problems related to alcoholism, prostitution, Other Health impacts
Socio-economical ImpactsVisible: Increase in Corruption/Co-optation of different actors, Militarization and increased police presence, Loss of landscape/sense of place
Potential: Displacement, Increase in violence and crime, Lack of work security, labour absenteeism, firings, unemployment, Loss of livelihood, Loss of traditional knowledge/practices/cultures, Social problems (alcoholism, prostitution, etc..), Specific impacts on women, Violations of human rights, Land dispossession
Outcome
Project StatusProposed (exploration phase)
Conflict outcome / response:Corruption
Preparing to implement study as national policy
Development of alternatives:Proposals for Chile to move towards 100% renewable energies with no new hydro, submitted by the Mesa Ciudadana del Cambio Climatico (Chile), a coalition of over 20 NGOs; Proposals for Chile to establish Wild & Scenic Rivers Designation and permanently protect key waterways in at-risk watersheds, being developed by International Rivers (global) and several local Chilean NGOs and attorneys.
Do you consider this an environmental justice success? Was environmental justice served?:Not Sure
Briefly explain:The Watershed Mapping Study is being finalized and will be presented in September 2016. While the methodologies used in the study has created some conflict in the seven watersheds being prioritized for hydro development, the full outcome of the study will only be seen if it is allowed to become national energy policy.

Related laws and legislations - Juridical texts related to the conflict

Law No. 1122 of 29.10.1981. El Código de Aguas

Law 20017. Created a royalty or tax applicable to owners of non-consumptive and continuous water rights who fail to utilize the waters. Specifically, the tax applies when owners fail to build infrastructure works to capture and restitute the waters. Law 20,017 provides that if the taxes are not paid, the courts may order the public auction of the respective water rights.

Article 28 of Law 19300. Related with "Community Participation in the Environmental Impact Assessment Process" page. 13

Law 19300 or the Environmental Framework Law, provides the basis for the organisation of environmental laws in Chile. It establishes the regulatory framework for environmental activity in Chile such as the environmental impact assessment system (EIAS), liability for environmental damage, air and water quality and emission standards, and pollution prevention and decontamination plans, among others.

Other comments:This is a local, regional, national and global conflict. Several watersheds in Chile are threatened by the same Watershed Mapping Study. These are rivers that deserve protected status, and it is expected that conflicts in Chile surrounding water rights will continue indefinitely until the country establishes new wild & scenic rivers legislation. Please review the map for information on the other watersheds at risk should the study become energy policy.
