Teck Carmen de Andacollo Switches to Renewable Power

September 17, 2020

Vancouver, B.C. – Teck Resources Limited (TSX: TECK.A and TECK.B, NYSE: TECK) (“Teck”) and The AES Corporation (NYSE: AES) announced today that their Chilean affiliates, Compañía Minera Teck Carmen de Andacollo S.A. (“CdA”) and AES Gener S.A (“AES Gener”), have entered into a long-term power purchase agreement to provide 100% renewable power for Teck’s Carmen de Andacollo Operation in Chile.

Under the agreement, CdA will source 72 Megawatts (MW) (550 GWh/year) from AES Gener’s growing renewable portfolio of wind, solar and hydroelectric energy. The transition to renewable power will replace previous fossil fuel power sources and eliminate approximately 200,000 tonnes of greenhouse gas (GHG) emissions annually, the equivalent to removing over 40,000 passenger vehicles from the road.

“Teck is tackling the global challenge of climate change by reducing the carbon footprint of our operations and working towards our goal of becoming carbon neutral,” said Don Lindsay, President and CEO of Teck. “This agreement takes Teck a step closer to achieving our sustainability goals, while also ensuring a reliable, long-term clean power supply for CdA at a reduced cost to Teck.”

“We are honored to continue working together with Teck to help them progress towards their goal of carbon neutrality,” said Andrés Gluski, AES Corporation President and Chief Executive Officer. “By providing Teck with innovative renewable energy solutions, AES Gener is helping build Chile’s sustainable and reliable grid of the future.”

As part of its updated Sustainability Strategy, Teck has set the goal of being a carbon neutral operator by 2050. In support of that that long-term objective, Teck has established milestone goals including sourcing 100% of all power needs in Chile from renewable power by 2030 and reducing the carbon intensity of operations by 33% by 2030. Teck previously announced an agreement with AES Gener to supply renewable power for the Quebrada Blanca Phase 2 (QB2) project currently under construction. Once effective, more than 50% of QB2’s total operating power needs will be from renewable sources.

The Carmen de Andacollo renewable power arrangement is in effect as of September 1, 2020 and will run through to the end of 2031.

“Switching to clean, renewable power for Carmen de Andacollo is another step forward in our ongoing commitment to responsible resource development across our operations and activities,” said Alejandro Vásquez, Vice President, South America, Teck.

“The contract we have signed with Compañía Minera Teck Carmen de Andacollo constitutes a new step in the execution of our Greentegra strategy. The agreement reflects the excellent relationships we have with our business partners, whom trust AES Gener as their provider of smart, innovative, competitive and sustainable energy solutions”, said AES Gener CEO, Ricardo Falú.

Carmen de Andacollo is a copper mine located in the Coquimbo Region of central Chile, approximately 350 kilometres north of Santiago. Teck owns a 90% interest in the mine. Empresa Nacional de Minería holds the remaining 10%.
