Chile Has So Much Solar Energy It’s Giving It Away for Free

Chile’s solar industry has expanded so quickly that it’s giving electricity away for free.

Spot prices reached zero in parts of the country on 113 days through April, a number that’s on track to beat last year’s total of 192 days, according to Chile’s central grid operator. While that may be good for consumers, it’s bad news for companies that own power plants struggling to generate revenue and developers seeking financing for new facilities.
Chile’s increasing energy demand, pushed by booming mining production and economic growth, has helped spur development of 29 solar farms supplying the central grid, with another 15 planned. Further north, in the heart of the mining district, even more have been built. Now, economic growth is slowing as copper output stagnates amid a global glut, energy prices are slumping and those power plants are oversupplying regions that lack transmission lines to distribute the electricity elsewhere.
“Investors are losing money,” said Rafael Mateo, chief executive officer of Acciona SA’s energy unit, which is investing $343 million in a 247-megawatt project in the region that will be one of Latin America’s largest. “Growth was disordered. You can’t have so many developers in the same place.”
A key issue is that Chile has two main power networks, the central grid and the northern grid, which aren’t connected to each other. There are also areas within the grids that lack adequate transmission capacity.
That means one region can have too much power, driving down prices because the surplus can’t be delivered to other parts of the country, according to Carlos Barria, former chief of the government’s renewable-energy division and a professor at Pontifical Catholic University of Chile, in Santiago.
“Michelle Bachelet’s government has set the energy sector as a priority,” said Carlos Finat, president of the country’s renewable association, known as Acera. “But planning has been focused in the short term when it is necessary to have long term plans to solve these type of issues.”
