On the floor, Ecuador’s reliance on hydroelectric tasks appears to be fulfilling the promise that was made within the nation’s 2008 Structure. This doc endorses federal assist for clear vitality adoption in Article 15, stating: “The State shall promote, in the private and non-private sectors, using environmentally clear applied sciences and non-polluting and low-impact different sources of vitality.” As of 2021, the Ecuadorian Ministry of Vitality reported that 92% of electrical energy technology got here from hydroelectric crops, of which there are 16 throughout the nation.

The nation continues to work in the direction of the aim of a inexperienced economic system, with a 2031 Electrical energy Grasp Plan that requires a 500 MW mixture of unpolluted vitality tasks throughout the nation. Nevertheless, The Electrification Grasp Plan 2013–2022 (Plan Maestro de Electricidad) made it clear that these renewable tasks would proceed to be centered on hydroelectric crops. This plan authorized 25 hydropower tasks which are deliberate to complete 4.2 GW (gigawatts) of recent capability by 2022. As compared, this plan allotted solely 217 MW (megawatts) for “photo voltaic, wind, and different non-conventional renewables.”

This dedication to hydroelectric energy created a renewable vitality market whereby wind, photo voltaic, and different renewable vitality tasks make up just one% of electrical energy technology. Regardless of the nation being dwelling to 3 utility-scale photo voltaic farms and three wind vitality websites, Ecuador is desperately reliant on its hydroelectric amenities. The risks of being too closely invested in hydroelectric change into clear when utilizing the Coca Codo Sinclair Energy Plant as a case examine. With a value of greater than $3.2 billion and building starting greater than 16 years in the past, the federal government on the time hoped this plant would serve to energy a brand new wave of industrialization in Ecuador. Nevertheless, the preliminary research accomplished in 1992 to verify feasibility proved to be insufficient, and Luis Torres, a Quito-based geologist and advisor, argues that “So far, the ability plant nonetheless lacks vulnerability and threat studies.” The lack of awareness on the environmental impression related to this venture has been underscored by the erosion of the Coca River.

The erosion that occurred because of the drying of the San Rafael waterfall in February of 2020 threatens the diversion reservoir and would require threat evaluation for the plant. As Fabricio Yépez, a professor of civil engineering in Quito, argued “This sort of venture wants technical choices so as to keep away from struggling hundreds of thousands in losses.” A rustic equivalent to Ecuador, that’s reliant on international capital for clear vitality investments, must be cautious of tasks inside the nation that constantly sap sources with out performing on the anticipated output. The struggles with the plant don’t finish with environmental issues, because the Corporación Eléctrica del Ecuador (Celec) filed authorized motion towards the inspector of the Coca Codo Sinclair hydroelectric plant on July 15, 2022. Celec claims this inspector authorized the receipt of kit from the plant regardless of having defects.

Coca Codo shouldn’t be the one instance of hydroelectric crops dealing with delays and infrastructure issues. Just one hydropower plant got here on-line between 2020–2022. The Toachi Pilatón venture, which was supposed to offer 254.4 MW of energy capability, has solely inaugurated certainly one of its three crops, as it’s 13 years behind schedule. As of April 2022, this venture has value $920 million, and has offered a fraction of the anticipated vitality.

Whereas the issues that accompany hydroelectric crops imply a failure to offer promised electrical energy throughout Ecuador, the silver lining could also be a dedication to beforehand underutilized sources of vitality. On April 30, 2022, Ecuador’s President, Guillermo Lasso, authorized the Villonaco III Wind Venture, which can change into the biggest wind energy plant in Ecuador. This plant required $181 million of funding, all coming from direct international buyers. A report from Mordor Intelligence additionally anticipated a photo voltaic compound annual development charge of 12% between 2019–2028. It’s value noting, nevertheless, that photo voltaic and wind tasks, together with the Villonaco Wind and Aromo Photo voltaic tasks, which have been awarded in December 2020, haven’t signed building contracts. Nevertheless, when in comparison with the last decade of delays confronted by hydroelectric initiatives, these new renewable sources have the potential to cement themselves as future sources of electrical energy technology.

Ecuador has an estimated 660 MW of solar energy capability. With the numerous decline in photo voltaic panel prices, the feasibility of photo voltaic funding in Ecuador has grown considerably. Juan Peralta, a renewable vitality specialist and professor of mechanical engineering in Quito, believes that photo voltaic has the higher hand over each wind and hydroelectric in future funding and set up as a consequence of location, simplicity of implementation, and reducing values.

Wind might additionally present a supply of sustainable and constant vitality for underutilized areas of Ecuador. There may be an estimated short-term wind potential of 884 MW, which may very well be utilized in mountainous areas equivalent to Cotopaxi and Chimborazo. This underscores earlier issues with hydroelectric energy. With the problem of putting in hydroelectric crops, and the excessive value of putting in crops in places which are onerous to entry, the places which are preferable for set up are already getting used. The present hydroelectric crops are primarily within the east of the nation, alongside the Andes mountain vary. Peralta believes that the remaining places which are possible for hydropower are within the Amazon, including extra value and issue of set up.

There isn’t any query that hydropower has been good to Ecuador. Nevertheless, diversifying the energies used inside Ecuador might put together the nation for ramifications of local weather change. As Rafael Soria, a researcher and professor at Universidad San Francisco de Quito argued, “The concept is to diversify the vitality combine in order to not rely upon a single useful resource that may very well be affected in the long run by local weather change.” Within the case of hydroelectric, which means water; and as we now have seen within the case of the Coca Codo venture, it is a very actual risk as Ecuador is presently in drought. By diversifying vitality sources, Ecuador can present insurance coverage towards the issues that come up when too reliant on hydroelectric energy.
