MARACAIBO, Venezuela, Mar 25 2024 (IPS) - Sweating profusely, unable to sleep because of the heat, fed up with years of blackouts several times a day, many residents of Venezuela’s torrid northwest want to cover the roofs and balconies of their homes with solar panels, and are asking the government to import them massively and cheaply from China.
“It is a proposal to break out of the quagmire immediately, to close the gap between supply and demand for electricity, 60 percent of which in Venezuela goes to residential consumption,” engineer Lenin Cardozo, one of the main promoters of the Zulia Solar and Venezuela Solar citizen initiatives, told IPS."The solution to the electricity problem no longer lies in thermal plants, which in Venezuela we continue to repair while they are being closed down in other parts of the world, but in new sources and technologies, such as solar power." -- Lenin Cardozo
The northwestern state of Zulia, of which Maracaibo is the capital, produced Venezuela’s great oil wealth throughout the 20th century but has become, along with the neighboring Andes region, the Cinderella of the grid that supplies electricity, generated mainly in the distant southeast of the country, bordering Brazil.
Zulia Solar emerged last year as an association to foment solutions to the lack of electricity suffered by millions of inhabitants of the region. And so far in 2024, replicas have emerged in twenty other states, with aspirations of becoming a national movement: Venezuela Solar.
Its president, lawyer Vileana Meleán, said that “the novelty is that this time the citizens are organized and we are coordinating among ourselves to present the government with this solution that arises from civil society, with a three-point proposal.”
The first point is for the government to massively import solar panels from China, the world’s leading producer – with which Caracas has developed strong commercial and political ties – in order to obtain advantageous prices, and for it to organize a distribution system that makes them affordable to households interested in installing them.
And the third point calls for the creation of a public and private financing policy, with soft loans, so that families of modest means can purchase the panels and other materials required for the new installation.
“When the electricity cuts off, the water goes out, the pumps don’t work. The food in the refrigerator spoils. During the day it is 40 or 42 degrees Celsius, but the thermal sensation reaches 47 degrees,” teacher Rita Zarate told IPS one afternoon in the hallway of her home in the working-class La Pomona neighborhood of Maracaibo.
For her family – mother, siblings, children, nieces and nephews – “the worst thing is not being able to sleep when the blackouts happen at night and in the early morning hours. In the bedroom, the heat is unbearable; outside, there are clouds of mosquitoes,” which swarm people in the house when the air conditioning or electric fans are turned off.
A sleepless night, trying to sleep when a breeze blows in the courtyard, keeping the elderly and little ones hydrated, and trying to get transportation to work at daybreak, which might not be available because the blackouts paralyze the fuel pumps and the owners of private vehicles spend hours waiting for the power to come back on so they can fill their tanks.
Zárate said that “it is the same for the children at school: classes two or three days a week, half a day, if they can run the fans. Or in the playground. Sometimes their parents leave them at home, other times the heat gets so bad that we have to send them back.”
Internet to study or to do work, to get administrative procedures done in offices, to operate ATMs in banks, to walk at night under street lights? These are options that are vanishing for those who live on the shores of Lake Maracaibo.
“In the last century Maracaibo was jokingly called ‘the coldest city in Venezuela’ because there was air conditioning everywhere. That’s not true anymore, they only work off and on now,” Luis Ramírez, director of the graduate program in quality systems at the private Andrés Bello Catholic University (Ucab), based in Caracas, told IPS.
He said that many homes in Zulia and the other 22 states outside Caracas have small gasoline-powered generators, but due to the scarcity of fuel – paradoxically, in the country that boasts the largest oil reserves on the planet – they are used less and less.
Zárate remains hopeful that change will come. But with regard to solar panels, he said that “I’ve heard about them, but it sounds like a distant solution,” and added that “one thing is for sure: with our income (every adult in his family earns less than 60 dollars a month) we won’t be able to afford them.”
Meleán proposed to her supporters in Zulia Solar and Venezuela Solar “to hold on now more tightly to the hope” that the acquisition and installation of solar panels will become widespread, based on a speech by President Nicolás Maduro, who is seeking reelection on Jul. 28 to a third six-year term.
At a Mar. 13 campaign rally, Maduro said that “the social movements have proposed a 2025-2030 plan for solar energy to reach the communal councils, the homes, the urban developments. It is one of the great solutions for the 21st century.”
At the end of the 20th century, Venezuela had a nominal installed generation capacity of 34,000 megawatt hours (MWh), including 18,000 MWh in thermal plants and 16,000 MWh in hydroelectric plants, and the peak demand of 18,000 MWh was reached in 1982.
From that year on, economic crises followed one after the other, reducing demand and the operability of the facilities. In the second decade of the 21st century, the country experienced a recession that cut GDP by four-fifths, while power plants and grids deteriorated until they generated no more than 10,000 MWh.
Experts put current demand at about 12,000 MWh, and the gap between supply and demand has led to energy rationing based on outages that affect almost the entire country – with the exception of Caracas – but especially the west, the region most distant from the southeastern Guri hydroelectric power plant, which generates two-thirds of the electricity consumed.
Zulia is barely surviving on what it receives from the Guri power plant and a dozen thermal power plants, which have deteriorated after being designed to be gas-fired and instead use diesel, contributing to their inefficiency and decline.
