Sun-drenched Chile understands how it can switch from being a consumer of coal and gas to a producer of renewable energy. Solar energy, in particular, is booming. With its more sustainable energy mix and fewer emissions, this Andean country is set to make a significant contribution to global efforts against climate change.
Chile’s economy is growing and so too is the country’s demand for energy, which now stands at roughly 6 per cent per year. This is mainly due to energy-intensive copper mining in response to the huge spike in global demand: the South American country happens to have the world’s largest copper reserves. Until now, Chile has generated more than 60 per cent of its electricity from – largely imported – fossil fuels, making it the country with the highest energy costs in all of South America.
By switching to renewable energy and using energy-efficient technology, the Government of Chile seeks not only to make industry more competitive, it also aims to reduce CO2 emissions by around one-third through to 2030 compared with 2007. The Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH is supporting the Andean country in achieving these environmental and climate-related targets.
A paradise for renewable energy
Commissioned by the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU), GIZ and Chile’s Ministry of Energy calculated the country’s potential in terms of wind, solar and hydropower. Their conservative estimate puts it at over 1,900 gigawatts (GW) – ten times the installed power capacity in Germany. In a nutshell, ‘Chile is a paradise for renewable energy,’ says GIZ’s Rainer Schröer, who manages the energy programme on site in Chile. Made up of various individual projects, the programme is proving successful: Electricity produced by large photovoltaic (PV) plants has increased from less than 7 megawatts (MW) to more than 2,100 MW within five years. And wind farms are now generating five times more electricity than they did in 2014.
Furthermore, under a public-private partnership with the German company Soventix GmbH, the programme has set up the first solar investment fund for financing relatively small PV plants. The fund has helped identify domestic and German medium-sized project developers and investors currently working on 25 PV plants with a total capacity of just under 80 MW. There are also plans to systematically harness solar power on top of public buildings, with over 110 solar power plants having been installed within a three-year period.
Germany and Chile share their knowledge
The key to wide-scale use of solar power consists in having adequate numbers of skilled professionals. GIZ has equipped six solar laboratories across the country that have since trained over 1,000 technicians. The federal enterprise also regularly organises trips to Germany for Chilean delegations for training purposes. Also with GIZ support, the University of Antofagasta, is setting up a training centre offering basic and further upskilling in concentrated solar power technology and PV field plants.
However, renewable energy also has to be harnessed appropriately for production purposes – which is why a public-private partnership with the German company Grammer Solar is promoting the use of solar-drying methods for agricultural produce. To show how it’s done, Grammer Solar installed a pilot, solar-powered plant for drying blueberries. By 2017, this partnership had resulted basic or further training for some 100 workers. Using this technology, medicinal plants and fruits can be dried carbon-neutrally and also more gently, helping farmers reduce costs and emissions. It also enables them to respond more targetedly to the growing demand for sustainably produced food.
All in all, with the support of the BMU-funded activities, Chile has increased the percentage share of power generated by the sun and wind from 5% to 17% since 2014. It has also reduced energy costs and enhanced energy supply security. Between 2007 and 2016, the South American country saved more than 20 million tonnes of CO2 by expanding renewable energy. However, it is ultimately not just Chile that is benefiting from the growing and innovative use of renewable energy sources. ‘If we avoid emissions, we protect the climate worldwide,’ says Rainer Schröer.
