Petacalco power station

From Global Energy Monitor

[español]

The 2100 MW Petacalco power station and its 678 MW Pacífico expansion collectively form the Central Termoeléctrica Presidente Plutarco Elías Calles, a 2778 megawatt (MW) coal-fired power complex in Petacalco, Guerrero, Mexico.

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 was added to create a seven-unit plant with a combined gross capacity of 2778 MW. All units are fueled with imported coal, mostly from Australia, Colombia, Canada and the United States.[3] Together they generate roughly 7% of Mexico's electricity.[4]

Pacífico coal-fired expansion project

The Pacífico coal-fired 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.[5]

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.[6] In the 2012 report, projected dates had slipped to 2024 for Pacífico II and 2025 for Pacífico III[7], and in the 2013 report, the dates were 2024 and 2026, respectively.[8] 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[9], projecting that coal-fired plants would produce only 4.5% of Mexico's electricity by 2028 (down from 9.7% in 2012).[10]

Environmental impact

The Petacalco power complex 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.[3] 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]
