칠레 발전소 AES Gener이 Angamos 북쪽의 석탄 화력발전소에 전원을 공급하는 담수화 플랜트에 대해 스페인 공학회사인 Abengoa와 계약을 체결했다고 밝혔다. 반대여론에도 불구하고 북쪽 도시는 담수화 프로젝트를 추진하기로 약속했다.
북쪽 Antofagasta의 AES 담수화 프로젝트는 처음 하루 4천800 ㎥ 용량 규모를 갖는다.
두 번째 개발 단계에서 시설은 하루 1만9천200㎥ 용량을 갖고 다른 고객에게 공급할 예정이다. Abengoa는 플랜트는 건설·운영할 예정이며 올해 공사에 착수해 1년후에 완공할 계획이다.
Aguas Antofagasta는 2014~2019년 동안 시설의 네트워크 향상과 물 수요 증가에 대처하기 위해서 1억4천500만 달러를 투자할 예정이며 2014년에는 총 투자의 45%를 투자할 계획이다. 또한 점진적으로 향후 4년 동안 균형적으로 확장할 예정이다.

Abengoa signs desalination deal with Chilean power group
Chilean generator AES Gener signed a contract with Spanish engineering firm Abengoa for a water desalination plant that will supply the power for the Angamos northern coal-fired power plant. And a water utility also in the north of country has pledged to forge ahead with a desalination project despite public opposition.
The AES desalination project, in northern Antofagasta will initially have a 4,800 m³/d capacity, the generator said in a release.
A second development phase could take the facility to 19,200 m³/d and supply other clients.
Abengoa will build and operate the plant, with works expected to begin this year and take 12 months to complete.
Meanwhile utility Aguas Antofagasta has said plans for the construction of its US$ 120 million second desalination plant remain unchanged despite community resistance.
The company said its plans to invest 80 billion pesos (US$ 145 million) during 2014-19 to upgrade its network and cope with growing water demand. And it will make 45% of its planned investment in 2014 with the balance spread over the next four years, chief executive, Hugo Masana said.
"We are looking to invest in upgrading infrastructure... building dams, improving technology and hiring new workers throughout the region," Masana told a national newspaper.
"Demographic growth in cities such as Antofagasta and Calama has put greater strain on our infrastructure," Masana said. He went on to says that water demand had increased 17% in Mejillones in recent years.
Aguas Antofagasta serves 161,000 people in the northern cities of Antofagasta, Calama, Mejillones, Taltal and Tocopilla, where some of the world's largest copper mines are located and water demand heavily exceeds supply.
Chilean President Michelle Bachelet has presented a national infrastructure plan that included US$ 9.9 billion in new concessions until 2020 and US$ 18 billion in public works projects until 2021 The plan involves the construction of two desalination plants in northern Antofagasta region and Atacama region.
