In Argentina, A Visit To World's Highest Solar Energy Park

With loans and solar panels from China, the massive solar park has been opened a year and is already powering the surrounding areas. Now the Chinese supplier is pushing for an expansion.

CAUCHARI — Driving across the border with Chile into the northwest Argentine department of Susques, you may spot what looks like a black mass in the distance. Arriving at a 4,000-meter altitude in the municipality of Cauchari, what comes into view instead is an assembly of 960,000 solar panels. It is the world's highest photovoltaic (PV) park, which is also the second biggest solar energy facility in Latin America, after Mexico's Aguascalientes plant.

Spread over 800 hectares in an arid landscape, the Cauchari park has been operating for a year, and has so far turned sunshine into 315 megawatts of electricity, enough to power the local provincial capital of Jujuy through the national grid.


It has also generated some $50 million for the province, which Governor Gerardo Morales has allocated to building 239 schools.

Abundant sunshine, low temperatures

The physicist Martín Albornoz says Cauchari, which means "link to the sun," is exposed to the best solar radiation anywhere. The area has 260 days of sunshine, with no smog and relatively low temperatures, which helps keep the panels in optimal conditions.

Its construction began with a loan of more than $331 million from China's Eximbank, which allowed the purchase of panels made in Shanghai. They arrived in Buenos Aires in 2,500 containers and were later trucked a considerable distance to the site in Cauchari . This was a titanic project that required 1,200 builders and 10-ton cranes, but will save some 780,000 tons of CO2 emissions a year.

It is now run by 60 technicians. Its panels, with a 25-year guarantee, follow the sun's path and are cleaned twice a year. The plant is expected to have a service life of 40 years. Its choice of location was based on power lines traced in the 1990s to export power to Chile, now fed by the park.

Chinese want to expand

The plant belongs to the public-sector firm Jemse (Jujuy Energía y Minería), created in 2011 by the province's then governor Eduardo Fellner. Jemse's president, Felipe Albornoz, says that once Chinese credits are repaid in 20 years, Cauchari will earn the province $600 million.

The Argentine Energy ministry must now decide on the park's proposed expansion. The Chinese would pay in $200 million, which will help install 400,000 additional panels and generate enough power for the entire province of Jujuy.

The park's CEO, Guillermo Hoerth, observes that state policies are key to turning Jujuy into a green province. "We must change the production model. The world is rapidly cutting fossil fuel emissions. This is a great opportunity," Hoerth says.

The province's energy chief, Mario Pizarro, says in turn that Susques and three other provincial districts are already self-sufficient with clean energy, and three other districts would soon follow.

The Dead And Disappeared: A Village Emerges From 72 Days Of Russian Occupation

Russian forces have been pushed out of the area around Kharkiv. Villages that were occupied for two months are free once more — but utterly destroyed. And thousands of people have disappeared without a trace.

Kharkiv and the surrounding villages faced weeks of constant Russian shelling.

TSYKRUNY — Andriy Kluchikov uses a walking stick, but is otherwise fairly sprightly for a 94-year-old. Under his black wool hat, Kluchikov seems fearless as he surveys his hometown in northeastern Ukraine. “The missiles don't scare me,” he says with a smile. “I have slept in my own bed every night and never went down into the basement.”

As for the two-meter-wide bomb crater that has appeared in his garden, between the vegetable patch and the greenhouse with its shattered plastic roof, Kluchikov almost seems proud. “No one can intimidate me,” he says. “Not even the Russians.”

In the early days of the war, in February, Russian artillery almost completely destroyed this village of Tsyrkuny, near Kharkiv, Ukraine's second largest city. Only a few houses, including his own, were left undamaged. Shortly afterwards, Russian troops marched into the village and occupied it for 72 days. It was not until early this week that the Ukrainian army was able to liberate Tsyrkuny and many other areas to the north of the country’s second-largest city, Kharkiv.

It is the Ukrainians’ most successful counter-offensive so far. They are thought to have pushed the invading troops back almost to the Russian border. “The offensive is gaining momentum,” according to the independent American thinktank Institute for the Study of War. “It has forced Russian troops on the defensive and has successfully alleviated artillery pressure on Kharkiv City.”

In the modern city of Kharkiv, home to around 1.5 million residents, the relief has been palpable over the last few days. Restaurants and cafes have reopened. People are walking and riding bikes in the parks, and couples are strolling hand in hand, enjoying the warm spring sunshine. You can still hear the artillery, but it is now many miles away.

Central to the tragic absurdity of this war is the question of language. Vladimir Putin has repeated that protecting ethnic Russians and the Russian-speaking populations of Ukraine was a driving motivation for his invasion.

Yet one month on, a quick look at the map shows that many of the worst-hit cities are those where Russian is the predominant language: Kharkiv, Odesa, Kherson.
