Four Reasons Why Chile Is the Biggest Solar Market in Latin America

Despite recent challenges, Chile remains an attractive market for grid-scale solar.

With the U.S. Federal government pulling back sharply from efforts to address global warming, I’ve found myself looking outside the United States for good news on climate.  One of the most compelling recent trends comes from Chile, the little-engine-that-could when it comes to solar power. Despite having only 3% of the population of Latin America, Chile has almost three-quarters of the installed solar generating capacity.


Some have pointed to the near-zero electricity prices, inadequate transmission, and other challenges in the Chilean market to suggest that these investments were somehow a mistake, or unsustainable. But I don’t buy it. Here are four reasons why Chile is, and will continue to be, a very attractive market for grid-scale solar.

#1: Electricity Demand Growth 

Electricity demand in Chile is forecast to increase 2.6% annually over the next two decades. Not impressed? The same number for the United States is 0.7%. Now it’s true that the last couple of years have seen slow growth, with the Chilean copper industry hurt by low copper prices in 2015 and 2016. But copper prices have been increasing since November and, moving forward, electric vehicles and batteries are expected to significantly increase global demand for copper. Historically, with the exception of a few hiccups, Chilean electricity demand has grown steadily for three decades.

Most of the future growth is expected to come, not from mining, but from Chile’s residential and commercial sectors. This is consistent with recent work by Catherine Wolfram and co-authors who find large scope for energy-demand growth in middle-income countries like Chile. In the coming years, Chile will continue to close the development gap between itself and high-income countries like the United States, and this means widespread adoption of lots of energy-using devices.

#2 The Atacama Desert

At-a-ca-ma!  Dry? The Atacama Desert in Northern Chile is the driest place on the planet.  Some parts of the desert have never seen a drop of rain since recordkeeping began. The Atacama is high, flat, and bone dry — the ideal location for solar. The sun beats down day after day with rarely a cloud in sight with some of the highest levels of solar radiation anywhere in the world.

Also important is that the Chilean government is expanding transmission, with an aim to connect Chile’s “Northern” and “Southern” grids by 2018. This is key for solar producers in the Atacama because the bulk of electricity demand is in the South, and the new transmission link will allow them to access Southern customers.

#3 Limited Natural Gas and Coal

Another key factor for Chile is that it does not have significant reserves of natural gas.  Chile has two LNG import terminals, but LNG is expensive, averaging two- to three- times typical prices for natural gas in North America. This is expensive enough that natural-gas fired plants struggle to compete with unsubsidized grid-scale solar.

Moreover, although Chile has rich copper and other mineral resources, it has very little coal. Coal can be imported, of course, but there is political opposition in Chile to coal based on environmental concerns.

 #4 Commitment to a Free Market

It doesn’t get mentioned as frequently, but another important factor is Chile’s commitment to the free market. Chile has been viewed as a bastion for free market economics since Milton Friedman and the “Chicago Boys” wielded great influence during the 1970s and 1980s. Deregulation and privatization have not always been good for Chile’s environment, but in this case the transparency of the market and lack of government interference has helped give private investors the confidence to enter the market aggressively. All electricity generation in Chile is privately owned, and there are over one dozen international firms operating in Chile’s solar sector.

The Chilean solar boom has occurred without any explicit tax on carbon or subsidy for renewables. The favorable conditions in Chile have nonetheless led to eye-poppingly low prices for solar. During auctions in August 2016, for example, the winning bid was $29.10/MWh, the lowest price ever for solar. Companies have had some trouble financing projects at these low prices, but the economic viability of these projects hinges on energy demand and supply forecasts, not about regulatory or political risk, which Chile has effectively minimized through its long-time laissez faire approach to markets.

Comparison to Mexico

The next big solar boom in Latin America is expected to happen in Mexico. Nearly half of projected solar installations for 2017 are in Mexico, and large contracts have been signed for 2018 and 2019. These investments may all go according to plan, but Mexico’s electricity market is less open than the market in Chile, so it makes these investments more risky for investors.

Perhaps the more important difference, however, is that Mexico has access to low-price North American natural gas. Natural gas is already the biggest source of electricity generation in Mexico, and 60% of new capacity between now and 2020 is expected to come from natural gas. Low-price natural gas doesn’t make it impossible to invest in renewables, but it does make it harder.


I’d be very interested if readers can come up with other potential explanations. But I’m pretty sure that these four explanations all play an important role. With good reason, Chile is the biggest solar market in Latin America. And, looking forward, none of these factors is likely to change overnight. After all, the Atacama has been dry for over 3 million years.

Chile is a fascinating case study that illuminates some of the broader underlying economics behind electricity markets. Some of these factors, like robust electricity demand growth, are present in a large number of other countries. Other factors, like the lack of natural gas reserves, are more unusual, though not unique to Chile.

  1. The last photo is of a solar array in the San Luis Valley of Colorado, with Mount Blanca in the background.

  2. Hello dear how are you?
    We are interested in your solar energy
    We are finding a project with my gouvernement in Mali about the solar energy we want know if you are interested in?
    Is a big market for solar energy because of Mali climate
    The degree of temperature is more than 43 degree
    We will travel to Chile about this project if it can interest you
    We will cooperate well
    Thank you for understanding me
    Best regards

  3. I agree. However, a key factor in Chile’s solar initiative success, in my view, started with the country’s success in addressing the role of the mining industry in the economy. At that, Chile joins a small number of countries who have been able to address the negative impact natural resource endowment has on an economy in the absence of strong institutional frameworks. Chile today ranks 10th in the Economic Freedom Ranking of the World. It also ranks high on the World Bank’s Doing Business Report and the Global Competitiveness Report of the World Economic Forum. It is the only member of the OECD from South and Latin America. It has been able to build strong institutional framework and a favorable investment climate. It is the stable institutional and regulatory framework that has allowed Chile to keep investors, to retain its highly professional technocrats, and economically outperform basically all resource rich countries combined. The reforms they embarked on started with reform of Chile’s Constitutional Mining Law. This step was followed by clear division of responsibility among the three branches of government. Mining sector reforms were then extended to the infrastructure sector particularly electric power. The institutional framework Chile built assisted in: the prevention of market failure and allocative inefficiency, increase in entitlements and government obligations and subsides, regulatory capture and the potential for collusion, reduced transaction cost particularly in the case of the industrial sector, reduced energy intensity and poor: technology – energy trade off, improved private sector investment and participation, enhanced privatization and sector reform, the removal of entry barriers to private-sector participation, and equitable redistribution of gains from reform and the removal of subsidies.

  4. Worth mentioning the mind blowing low bid of 6.3c/kWh for dispatchable solar thermal+storage 24h baseload power recently put forward by Solar Reserve.

    You might also mention that with a latitude of 23 degrees south, the Atacama desert gets more even seasonal insolation then anywhere in the US.

  5. Chile is finally tapping into the huge potential renewable energy sources can provide to fuel in a carbon-free the future needs of the country and that of its neighbors. The solar, wind, geothermal, and marine resources can easily be integrated to cover all of its needs. Of course, energy efficiency and conservation must also be the key component of its energy sector development. Accelerated investment in transmission and move to renewables rather than fossil fuels, under one government, with enormous untapped human capacity, will enable Chile to be the beacon for Latin America and provide a professhional andn economic growth opportunity for its citizens. Many of us in Chile and abroad have pointed this out for decades! I am very happy to see it finally happening despite fossil-fuel vested interests push back.

  6. I like the reason you gave Lucas, plus the fact that with their stable, strong economy comes ready access to financing. But, solar growth in Chile will slow due to transmission constraints. You are right about Mexico – that is going to be the next big market – in 2016 over 4GW of solar contracts were signed.
