Anla has upheld its decision to reject the permit request for the 152-MW Piedra del Sol hydro project in Colombia, citing deficiencies in information related to the project’s impact on water supply and fragile ecosystems in northern Santander department, among other factors.
Anla is short for Autoridad Nacional de Licensias Ambientales and is Colombia’s environmental regulator.
Isagen and HMV propose to develop the Piedra del Sol facility.
Anla issued its refusal previously in September 2016, and Isagen and HMV filed an appeal in December 2016.
The project would be located on the Fonce River between the Cabrera, Pinchote, San Gil and Socorro municipalities. It is expected to cost US$300 million to develop and would be built to meet the need to expand the Colombian energy grid for domestic and industrial use, according to BNamericas.
Isagen also was working to advance development of the 960-MW Canafisto project, but Anla denied its environmental license as well, in January 2017.
Anla launched a public consultation process regarding the terms of reference for preparing an Environmental Diagnosis of Alternatives for the construction and operation of hydroelectric plants in March 2018.
