Background

Launched in 2006, the Bocamina II project is an expansion of the pre-existing Bocamina I power plant, which dates to 1970.[1] In 2007, Bocamina II received its environmental permit pursuant to an EIA (environmental impact assessment). However, after a 2008 design modification intended to increase the plant's safety, performance and generating capacity (from 350MW to 370MW), the national fishermen's alliance Confepach (Confederación Nacional de Federaciones de Pescadores Artesanales de Chile) demanded that the plant be required to obtain a new EIA, and in July 2012, Chile's Supreme Court ruled in Confepach's favor. [2]

In December 2013, in response to a new suit filed on behalf of local fishermen, Concepción's court of appeals ordered that Unit 2 be shut down indefinitely, citing the plant's failure to obtain the required environmental impact report.[3] In January 2014 Chile's environmental regulator also halted operations temporarily at the adjacent Bocamina I plant [4], but that unit returned to service in February 2014.[5]

In August 2014 Bocamina II was fined $4.7 billion pesos for environmental violations, and these sanctions were upheld in March 2015 by the Environmental Court of Valdivia.[6] In April 2015 regulators issued a permit for Bocamina II to return to service pending installation of a state-of-the-art filtration system designed to protect marine life.[7] In July 2015, Endesa announced that the Bocamina II plant had resumed operations.[8]

In April 2017, the Chilean environmental agency SMA (Superintendencia del Medio Ambiente) fined the Bocamina plant 575 million Chilean pesos for excessive emissions of pollutants in 2014, including sulphur dioxide, nitrogen oxide and particulate matter.[9]
