Background
The Tocopilla power station is owned by Engie and operated by Engie Energía Chile S.A. (formerly E-CL / Electroandina).[9][10] 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.[10]
Engie decommissioned the subcritical Units 12 (87 MW) and 13 (86 MW) in 2019[11] and Units 14 (136 WM) and 15 (132 MW) in 2022.[12][13][10][14][15]
As of 2023, 398 MW remained in operation at the station's gas-fired, combined cycle Unit 16. [16]
Retirement of coal-fired units
In February 2018 Chilean president Michelle Bachelet announced that Chile would phase out coal-fired plants,[17] and Engie announced that it would close its coal-fired plants in Chile.[18] Engie had previously announced that it would try to sell the plants to new operators instead of closing them.[18]
In June 2019 the Chilean government announced that all four of the Tocopilla plant's coal-fired units 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.[19]
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.[20] Engle's subsequent plans have called for Mejillones 4 to be converted from coal to natural gas by 2025.[21][22][23]
Units 12 & 13
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.[24]
Units 12 and 13 were retired in June 2019.[11]
Units 14 & 15
In June 2018 Engie added Tocopilla 14 to its scheduled closure list.[25] In December 2019 Engie announced that Units 14 and 15 would be retired in January 2022 instead of a previously planned date of May 2024.[12] As of December 2020, Units 14 and 15 remained on schedule for decommissioning in January 2022.[14]
However, in December 2021, Chile's National Energy Commission (CNE) requested that Engie postpone the closure of both units until at least June 2022 to ensure grid reliability.[15][26] Engie confirmed the delayed closure date in an April 2022 presentation to investors.[27] The company was obliged to rehire 13 workers at the Tocopilla plant to comply with CNE's request.[28]
In July 2022, Engie announced that it had disconnected Tocopilla's coal-fired unit 14 from the grid as of June 30, and confirmed plans to retire unit 15 on September 30, 2022.[29][30] Later the same month, Chile's National Energy Commission passed a resolution officially confirming the September 30 retirement date for Tocopilla 15.[31]
On September 30, 2022, Unit 15 was shut down as planned, putting an end to Engie's use of coal-fired power at Tocopilla.[32][33]
Conversion to Battery Energy Storage System
According to reporting from April 2024, Engie was planning to spend US$180 million to convert the retired Tocopilla coal plant into a 116 MW standalone battery energy storage system (BESS).[34]
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.[35]
