Background

The Petacalco power station is Mexico's largest coal-fired power plant, and the third largest overall among the country's 71 power plants.[1] Petacalco's six original 350 MW units were brought online in 1993 and 1994.[2] In 2010 the 678 MW Pacífico expansion unit (sometimes referred to as unit 7) was added to create a seven-unit plant with a combined gross capacity of 2778 MW.[3][4] The Petacalco plant generates roughly 7% of Mexico's electricity.[5][6]

In Mexico's 2023-2037 National Electric System development plan, the Petacalco power station was mentioned and appeared to be operational with no future plans of retirement noted.[7]

Fuel

The Petacalco plant uses a dual-fuel system, with units 1 through 6 capable of running on coal or fuel oil[8][9]; the Pacífico expansion unit is fueled exclusively by coal.[9] Coal for the plant has traditionally been imported from Australia, Colombia, Canada, the United States and Asia through the Port of Lázaro Cárdenas[4][8][10], because Mexico's domestic coal, mostly produced in Coahuila state, does not meet the Petacalco plant's thermal specifications.[8] Under the administration of President Andrés Manuel López Obrador, the Petacalco plant has increased its consumption of fuel oil and reduced its consumption of imported coal, in accordance with government policies favoring domestically produced fuels.[8][9][11][12]

In February 2021, Forbes México reported that Mexico City's Ministry of Works and Services was planning to build a "hydrothermal carbonization plant" that would produce biofuel to be used at Petacalco power station.[13]

According to the 2021 annual report of Mexico's federal electricity commission (CFE), domestic liquid fuels played an important role in powering the Petacalco plant throughout 2021.[8][14] As of November 2021, news sources reported that the plant was operating at only 30 to 40% of its capacity, with units 1, 4 and 7 out of service due to fuel shortages[9]; CFE acknowledged that only three units of the plant were operating, but maintained that it was providing adequate supplies of fuel, including coal, to the plant.[15][16][17]

Mexico's 2023-2037 National Electric System development plan noted that in 2022, the Petacalco power station was using both fuel oil and coal to generate power.[7]

Pacífico expansion project

The Pacífico expansion project, known locally as Carboeléctrica Pacífico or by its official name Proyecto 62 CCE Pacífico, was a proposed three-unit addition to the plant. The first unit, Pacífico I, was brought online in March 2010. The other two units, Pacífico II and III, were announced as potential long-range projects but subsequently cancelled.

In December 2005, Mexico's Comisión Federal de Electricidad (CFE) contracted Mitsubishi Heavy Industries to begin construction of the Pacífico addition, which was announced as Mexico's first supercritical coal-fired power plant.[2] The Pacífico I expansion (also known as Petacalco Unit 7) began commercial operations in March 2010, with a gross capacity of 678 MW and a net capacity of 651 MW.[18][3]

Two additional units (Carboeléctrica del Pacífico II y III), projected to generate another 1400 MW, appeared in the Mexican government's 15-year energy plans issued in 2011, 2012, and 2013. However, estimated completion dates for both projects slipped with each annual update. In the government's 2011 report, both plants were listed with projected completion dates between April 2021 and April 2023.[19] In the 2012 report, projected dates had slipped to 2024 for Pacífico II and 2025 for Pacífico III[20], and in the 2013 report, the dates were 2024 and 2026, respectively.[21] Neither plant appeared in the 15-year plan issued in 2014, and the 2014 report noted that price competition from natural gas had prompted a reduction in Mexico's use of coal for electricity generation[22], projecting that coal-fired plants would produce only 4.5% of Mexico's electricity by 2028 (down from 9.7% in 2012).[23]

Environmental impact

The Petacalco power complex has had significant negative impacts on human health, marine life, fisheries and agriculture in northwestern Guerrero state.[24][25][26] The Petacalco plant burns an average of 7 million tons of coal per year and has been described as one of the world's worst polluters. Its annual emissions of carbon dioxide and mercury (over 15 million tons, and 711 tons, respectively) are the highest of any power plant in Mexico. In addition, it ranks second nationally in annual emissions of nitrous oxide (228 tons) and methane (152 tons), third in nitric oxide (over 24,000 tons), and fifth in sulfur dioxide (152 tons per year). Air and water pollution traceable to the plant have created multiple negative impacts for surrounding communities, including depletion of fisheries, loss of mangrove habitat, and high concentrations of coal ash and other particulates that threaten residents' health.[4] The Petacalco power plant, together with the José López Portillo and Carbón II power stations in Coahuila state, accounts for 22% of the GHG (greenhouse gas) emissions from Mexico's electricity sector while contributing only 10% of national electricity production.[1][27][28]

Citizens' groups have organized frequent protests and meetings with Guerrero state government officials to highlight their concerns about the Petacalco power station's environmental and health impacts, including severe air pollution and contamination of local fisheries.[29][30][31][32]

In June 2023, the mayor of Guerrero led community members and local groups in a peaceful protest against the perpetual environmental degradation caused by the power plant's combustion of fossil fuels.[33]
