The Hoax of Free Energy Machines

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

    Many of you will comment that is a misleading headline…and it is. But its energy and its 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.

    chiledownloadChile’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.

    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.”

    Inadequate Infrastructure

    The government is working to address this issue, with plans to build a 3,000-kilometer(1,865-mile) transmission line to link the the two grids by 2017. It’s also developing a 753-kilometer line to address congestion on the northern parts of the central grid, the region where power surpluses are driving prices to zero.

    Solar Growth

    Solar capacity on Chile’s central power grid, known as SIC, has more than quadrupled to 770 megawatts since 2013. Much of that comes from the grid’s northern sections, the Atacama region that’s home to the copper industry. Total installed capacity increased 5 percent in the past year, with half coming from solar farms, according to the grid operator, Cdecsic. SIC supplies power to the regions where 90 percent of the country’s residential demand is located.

    The country is expected to install almost 1.4 gigawatts of solar power this year, up from 371 megawatts in 2015, according to Bloomberg New Energy Finance.

    When power companies aren’t giving away electricity, it’s cheap. At the Diego de Almagro substation in the Atacama region, for example, prices didn’t exceed $60 a megawatt-hour for most of March. That’s less than the $70 minimum price for companies that won long-term contracts to sell solar power in Chile’s energy auctions in October and March.

    The issue may limit future development because the uncertain revenue means banks will be reluctant to finance new power plants, according to Rodrigo Violic, head of project finance at the Chilean lender Banco Bice. “It’s a big problem,” he said.
