Chile's Transition to a Clean Energy Matrix


As Posted on American University's Center for Latin American and Latino Studies Blog, September 11, 2017

Since Michelle Bachelet’s return to the presidency in March 2014, Chile has aggressively pursued an ambitious program to transition the country’s energy matrix toward non-conventional renewable resources. The emphasis on non-conventional includes mini-hydro facilities with a generating capacity under 20 Megawatts, geothermal, solar, wind, biomass, and potentially ocean currents. Chile aims to generate 60 percent of its electricity from domestic renewable energy resources (including all forms of hydro) by 2035, and 70 percent by 2050. To encourage that transition, Chile is one of only two Latin American countries (the other being Mexico) to establish a carbon tax, under which energy-intensive industries and utilities that exceed mandated emissions levels are charged US$5.00 per ton of CO2 emissions. Chile’s drive to adopt a cleaner energy matrix is motivated as much by a desire to reduce greenhouse gas emissions as it is to enhance energy security.

Follow up:

During the mid-1990s, Chile faced consecutive years of severe drought that had hugely detrimental impacts on the country’s dams, responsible at the time for around 50 percent of the country’s electricity. An abundance of natural gas in neighboring Argentina led to the construction of pipelines across the Andes and new thermal generators in Chile, but Argentina began cutting natural gas exports in 2004 (eventually stopped them altogether) because disastrous policies there had caused domestic shortages. Bolivia, in turn, rebuffed Santiago’s entreaties to purchase its gas unless Chile granted it territorial compensation for the loss of Bolivian access to the Pacific after the 19th century War of the Pacific. Chile had to build two expensive receiving terminals to import Liquefied Natural Gas (LNG) from East Asia as well as Trinidad and Tobago. The Chileans were also forced to use more coal and diesel, exacerbating the already precarious air quality in many Chilean cities, particularly during the winter.
In recent years, more than half of all investment in non-conventional, renewable energy in Latin America and the Caribbean has been directed to Chile, primarily to build solar and wind parks to supply the mining industry in the north of the country. The shift to renewable energy has largely been financed by the private sector, with no subsidies other than reimbursement for small-scale photovoltaic and other nonconventional contributors to the grid at the full retail price (and no transmission charge). Chile’s antipathy to subsidies reflects the country’s market-based economic orientation and a conscious decision to prioritize state-of-the-art renewable technology sourced from elsewhere rather than encourage the development of its own industry. The recent investment boom in renewables was driven by the business-friendly climate, the fact that Chile is not a significant hydrocarbons producer, and the inflationary impact of the last three years of drought on the price of hydroelectricity.

Chile has several other things going for it in achieving its goals, including a good regulatory framework and resources that are in growing demand. Chilean regulators allow generators to sell electricity in only one of three time blocks during the day -- giving solar and wind power a competitive edge in public purchase agreement auctions. This more than halved the bidding price offered by generators and made solar power competitive with natural gas and even electricity sourced from hydro. In the near future, as the country’s energy matrix shifts to greater reliance on solar and wind power, Chile intends to utilize hydroelectricity to supply peaks in demand for electric power (usually in the evening hours) to make up for intermittencies in sunshine and wind. (At the moment, fossil fuels provide that function.) New developments in storage technology will also help. Chile is one of the world’s largest producers of lithium, needed to make storage batteries. The interconnection of Chile’s northern and central grids in 2018 should also facilitate greater use of different renewables and redirect the electric power generated from them to where it is most needed. Chile, already a leader in Latin American alternative energy production, is poised to enhance that position.
