“…The analysis consisted of the comparison with other types of generation technologies using different resources available in the country. An analysis of the main disadvantages of the hydropower generation technology in the tropical areas during the effects of ENSO phenomenon was also performed [13,29]. This last aspect results to be important in the energy development planning of the country, the intermittency in the resource affects directly the rate of energy production in a stable way.…”

“…The hydroelectric has the biggest share of the energy mix in the country, even during the year 2015 when the strongest ENSO phenomenon was reported, which affects the generation performance due to the low level in water reservoirs. Nevertheless, the national energy demand increases from 3.9 to 4.4 % by year [2], showing the situation above as an important risk for the national energetic security in the country [13].…”

“…have been more frequent, gradually stronger, and more severe over the last 20-30 years than they were during the preceding hundred years [33]. The recent years in Colombia have been characterized by an increase in the area averaged temperature [13]. The precipitation rates and surface temperature for Colombia, specifically in the region of -81.5625 long, -4.5703 lat,-64.6875 long, and 14.0625 lats (Figure 1), were retrieved for the years between 2010 and 2017 to graphically represent the effect of ENSO phenomenon that took place in 2015, and the climate change through these variables ( Figure 4).…”

“…The share of hydropower in the Latin American countries such as Ecuador is about 40 %, which is a lower percentage in comparison with the share in Colombia [8,11,12]. This circumstance became an important case of study for strategic energy planning in Colombia [13].…”

“…ENSO is recognized as an influential climate pattern on meteorological variables such as global solar radiation, wind speed, and precipitation rates, affecting directly the hydropower supply [14,15]. Colombia, as a dependent country on hydroelectric power generation technologies, is sensitive to climate change [13]. This strong dependency makes climate change an issue to be included in the development plan of the country.…”

In Colombia, hydropower share was 70 % of the total installed capacity and more than 50 % of the monthly generation share in 2015, which coincided with the strongest El Niño Southern Oscillation (ENSO) phenomenon reported in the region. ENSO has been recognized as an influential climate pattern on meteorological variables. The generation via hydropower implies the construction of dams and water reservoirs; these flooded areas generate an important amount of Green House Gases (GHG). In this regard, the main aim of this research was to quantify the diffusing emissions of CO2 and CH4 in the flooded areas of the main hydroelectric power generation facilities in Colombia. GHG emissions were calculated by the implementation of an IPCC methodology. The obtained results show that more than 1,042,500 t CO2-Eq (i.e. CO2 and CH4) are emitted in Colombia per year from this source, representing 4.4 % of the total GHG emissions in the country. As the second aim, the vulnerability of Colombia’s energy independence, in terms of power supply to ENSO and climate change was analyzed using the MERRA-2 dataset from NASA, for the years between 2010 and 2017.

The Magdalena River mouth in Colombia is studied as a candidate site for a renewable power plant via osmotic energy technology, using pressure retarded osmosis. This power generation plant would operate through the controlled mix of two flows with different salinities (river water and sea water in this case study). A preliminary design of a pressure retarded osmosis power plant is proposed here by means of experimental data acquisition on-site at the river mouth. The obtained net power production is shown to reach 6 MW, with adequate membrane power densities above 5 W/m 2. These promising results consider energetic losses involved in the process, which have been further analysed to propose improvement targets in pretreatment processes and membrane permeability.
