A miner and a retailer are among the latest corporations in Chile to sign up for renewables through energy supply agreements with energy retailers rather than power purchase agreements with individual wind and solar projects.

The Antucoya copper mine in the Antofagasta region, which is 70% owned by Antofagasta Minerals and 30% by Marubeni Corp., has inked an 11-year supply deal with Engie Energia Chile for 300 GWh a year beginning on January 2022.

The contract is similar to a 10-year agreement signed last year for Antofagasta and Barrick Gold Corp.'s Zaldívar copper mine from 2020, though the supplier in that case is Colbún (PFR, 7/13/18).

Department store chain Ripley, meanwhile, has signed a five-year deal with Colbún for 90 GWh a year from a mixture of hydro, solar and wind sources.

The generation will power 27 Ripley stores in Chile as well as the company's corporate building and distribution centers. The contract went into effect May 1 and covers more than 60% of Ripley’s electric demand.
