Tocopilla Power Station

From Global Energy Monitor

[español]

Tocopilla Power Station is an operating dual-fuel power station in Tocopilla, Antofagasta, Chile. Its coal-fired units 14 and 15 have a combined generating capacity of 268 MW, while the gas-fired unit 16 has a capacity of 362 MW.[1]

Background

The Tocopilla power station is owned by Engie and operated by Engie Energía Chile S.A. (formerly E-CL / Electroandina).[2][3] Four coal-fired units (Units 12-15) were brought online at Tocopilla during the 1980s, followed by a natural gas-fired unit (Unit 16) in 2001.[3] Engie decommissioned Units 12 and 13 in 2019[4] and plans to decommission Units 14 and 15 in early 2022.[5]

Planned phase-out of coal-fired units

In February 2018 Chilean president Michelle Bachelet announced that Chile would phase out coal-fired plants,[6] and Engie announced that it would close its coal-fired plants in Chile.[7] Engie had previously announced that it would try to sell the plants to new operators instead of closing them.[7] In April 2018 Engie announced that it was seeking permission to disconnect Tocopilla Units 12 & 13 from the grid and that shutting them down would take 12-36 months.[8] In June 2018 Engie added Tocopilla 14 to its scheduled closure list.[9]

In June 2019 the Chilean government announced that the plant would be retired by 2024 as part of a plan to reduce the country's annual CO2 emissions from the current 30 million tonnes (tons) to four million by 2024.[10]

Unit 12 and Unit 13 were retired in June 2019.[4] In December 2019 Engie announced that Unit 14 and Unit 15 would be retired in January 2022 instead of a previously planned date of May 2024.[11] As of December 2020, Units 14 and 15 remain on schedule for decommissioning in January 2022.[5]

Despite the closure of the Tocopilla units, Chilean environmental groups note that Engle has actually increased its carbon footprint in Chile’s Antofagasta region with the May 2019 commissioning of the company’s new 375MW Mejillones Unit 4 – the largest coal-fired power plant in Chile.[12]

Environmental concerns

A 2019 joint study by Chile’s Universidad Católica and Chile Sustentable found that coal-fired power plants pose significant health threats to residents of Chile's Norte Grande region, with people living near the Tocopilla power station suffering markedly higher rates of lung cancer, asthma, heart disease, and related illnesses.[13]
