Copec EMOAC secures 156.5 GWh renewable supply deal with Minera Arqueros in Chile

Copec EMOAC signed a renewable electricity supply agreement with Compañía Minera Arqueros to deliver approximately 156.5 GWh of clean energy to the copper concentrate producer’s operations in Chile’s Coquimbo Region. Minera Arqueros, a Chilean subsidiary of Japanese company Nittetsu Mining Co., operates a copper mining project focused on energy efficiency and technological innovation. The contract advances the mining company’s decarbonization targets while supporting operational competitiveness through renewable energy adoption.

The agreement follows a pattern of industrial renewable procurement facilitated by Copec EMOAC. In April 2026, the company secured a 10-year, 3-month contract with Suralis, a sanitation operator in southern Chile, to supply 40.08 GWh annually starting April 1, 2026. That deal covers electricity consumption across multiple facilities in Osorno, Puerto Montt, Puerto Varas, and La Unión, powering water production, distribution, and wastewater treatment operations with 100 percent renewable sources.

Copec EMOAC’s supply capacity received a significant boost through a 15-year power purchase agreement with METLEN for 450 GWh annually, beginning in the second quarter of 2026. The METLEN contract features energy delivery during non-solar hours—defined as 19:00 to 07:59 in winter and 22:00 to 06:59 in summer—backed by 322 MW of battery energy storage systems across four solar plants: Willka, Doña Antonia, Tocopilla, and Tamarico. This structure addresses price volatility during periods when solar generation drops and the system typically relies on gas-fired generation or spot markets.

Mauricio Olivares, commercial director at Copec EMOAC, characterized the Minera Arqueros agreement as demonstrating how long-term partnerships deliver concrete contributions to industrial sustainability goals. Yoshiharu Tsukayama, general manager of Minera Arqueros, emphasized Chile’s global leadership in renewable energy and positioned the contract as reflecting commitments to greenhouse gas reduction and responsible energy use aligned with Japanese corporate sustainability standards.

The accumulation of supply contracts positions Copec EMOAC as an intermediary aggregating renewable energy for diverse industrial sectors including mining, sanitation, and potentially others, while battery-backed nighttime delivery capabilities differentiate its offering in a market experiencing rapid solar capacity additions.
