Use of water for electricity generation triggers outcry in Mexico
One of the fears of the people of the Sierra Huasteca mountains in the state of San Luis Potosi in northeast Mexico is the construction of combined cycle power plants, which would threaten the availability of water.
“We have heard rumors about the installation of two more plants, but we have no information. They operate with very obscure mechanisms,” said Esther Peña, an advisor to the non-governmental Coordinator of Peasant and Indigenous Organizations of Huasteca Potosina, which was founded in 1994 and which brings together 12 organizations of indigenous people and small farmers in six municipalities, IPS wrote.
Peña said that the Tamazunchale combined cycle plant, which has been operating since 2007 with a capacity of 1,187 megawatts, is polluting the environment and damaging coffee and citrus plantations, as well as cattle ranching.
The Spanish company Iberdrola, which owns the plant, plans to build two additional plants, Tamazunchale I and II, with a total capacity of 1,187 megawatts, which are still in the design phase.
The expansion of these natural gas-fired thermal power plants, whose waste gases are reused to produce more energy from steam, is a concern for defenders of water and enemies of fossil fuels because of the social and environmental impacts.
The threats identified by these groups also include the extraction of unconventional hydrocarbons from shale and the use of water by mining companies, soft drink plants and other industries.
They were all discussed this month by experts and community leaders in Tlamanalco, a city in the state of Mexico, in the southcentral part of the country
During the National Workshop of Promoters of Water and Basin Councils, 121 representatives from 51 Mexican organizations analyzed how to redress the impact of these activities on access to water, as well as how to promote solutions that put water management in the hands of citizens.
The emphasis of this vision is on community management of water, the human right to water access, the care of water and water quality, as laid out in the proposed General Water Law, drafted since 2014 by civil society organizations, academics, local communities and indigenous peoples.
The organizations elected representatives from 28 basin councils, who will carry out the local work of disseminating the citizens’ initiative and mobilizing support.
From this perspective, the link between water and energy becomes relevant, above and beyond the construction and modernization of hydroelectric power plants and amidst the impacts of climate change caused by the extraction and burning of fossil fuels.
“Today, the vision of using water to produce energy, such as in hydropower plants, combined cycle power plants and natural gas, has taken hold. Water is being misused,” said Óscar Monroy, president of the non-governmental Amecameca and La Compañía River Basin Commission.
The activist said, “The problem is getting worse, because the current law considers water a commodity. The government subsidizes water for the big polluters.”
Monroy was one of the participants in the meeting in Tlalmanalco — which means ‘place of flat land’ in the Nahuatl language — a city of 47,000 people about 50 kilometers southeast of Mexico City.
Encouraged by the importation of natural gas from the US, the state-owned Federal Electricity Commission (CFE) and private companies are working on the assembly of combined cycle power plants, favored by the opening of the energy sector to private capital in 2014.
The 2017 report ‘Neoliberal threat to common goods: national outlook for electricity megaprojects,’ prepared by the non-governmental company Geocomunes, indicates that the CFE currently operates at least 27 thermoelectric, combined cycle and turbo-gas power plants, while there are at least 22 others in private hands.
Another 16 plants of this type are currently in the project stage and the CFE is building at least six additional plants that will come into operation in the coming years, according to data from the state agency.
In the second electricity auction, in September 2016, the Mexican government awarded a CFE combined cycle project in the northern state of Sonora and another private project along the border with the US, in the northeastern state of Tamaulipas, while in the 2017 electricity auction, two other private facilities were awarded.
By 2017, the autonomous public Energy Regulatory Commission had granted 645 permits for fossil fuel power generation — including combined cycle thermoelectric plants — equivalent to half of the authorized total.
In the first quarter of 2018, combined cycle plants, whose consumption of water for driving steam turbines is unknown, contributed 30,920 megawatts of the national total of 75,570 megawatts.
Several studies predict a water crisis in Mexico by 2040, especially from the center to the north of the country.
Of the 653 national aquifers, 105 are overexploited. Data from Oxfam Mexico indicate that almost 10 million people, out of the 130 million who live in this country, lack water in their homes, so that using water for generating energy conflicts with these needs.
