Impacts of Ventana Unit 4. The latest addition to AES Gener's Ventanas coal-fired complex, Campiche was originally scheduled for completion in May 2011. However, in June 2009, Chile's Supreme Court ordered that construction be  halted, citing improper zoning of the plant. AES Gener had already completed 40% of the $500 million project before it was halted. Subsequent regulatory changes allowed construction of the plant to resume, but the project was again suspended in early 2010 as Puchuncaví municipality took legal steps against the plant due to environmental concerns. In July, 2010, AES Gener reached an agreement with Puchuncaví to renew construction of Campiche, promising in return to invest nearly US$80 million in environmental improvements of the company's local thermal power plants, in public projects and forestation. The plant was brought online  in March 2013. In late December 2013, several tons of sardines washed up dead on Ventanas beach near the plant, spurring renewed controversy over Campiche's environmental impact and prompting calls for suspension of operations.
