The publicly owned company Econssa Chile S.A., responsible for ensuring access to potable water and wastewater collection and treatment services in nine regions of the country, has awarded Acciona the supply of 100% renewable electricity to the desalination plant it is now building in the municipality of Caldera in the region of Atacama.
According to the terms of the PPA, the contract will come into effect in November 2019, with a long-term horizon to cover all the desalination plant’s electricity requirements. It is the sixth PPA for the supply of energy singed by Acciona in Chile.
1,200 liters of water per second
In a context of water shortages in many parts of the country, Econssa has been building a seawater desalination plant since early 2018. Its total production capacity of 1,200 l/s will cover the consumption of people living in four municipalities in Atacama. Until now, this supply was covered by a spring.
Initially, the electricity supplied will allow Econssa to carry out the first technical tests on the plant. The energy supply will gradually increase as the three stages of the start-up of the plant are completed, from 450 l/s in the first phase to 1,200 l/s when it is operating at full capacity.
Sixth PPA in Chile
The supply contract signed with Econssa joins others signed with major corporate clients in Chile. For example, with Google for the supply of electricity to its data center; the distribution chain Falabella, to supply around one hundred stores of the group and its subsidiaries; Aguas Chañar for its end-to-end water facilities in the region of Atacama; LATAM Airlines Group for its corporate offices and operation and maintenance base in Santiago airport, and the National Mining Company of Chile (ENAMI) to supply its plants in the regions of Antofagasta, Atacama and Coquimbo, as well as the consumption associated with the modernization of a publicly-owned copper casting facility.
Acciona has also signed supply contracts with all the distributors and cooperatives in the country following an energy tender for the consumption of regulated clients called “Tender 2013/03, 2nd call” and “Tender 2015/01”.
