Challenges for unconventional renewable energies

Experts spoke about the challenges and opportunities for unconventional renewable energies.

They agreed that reliability, competitiveness, and the entry of projects auctioned in 2019 are the country’s main challenges in this topic, La Republica reported.

Siemens Energy’s Guilherme de Mendonca said that one of the main opportunities for this process is green hydrogen. He acknowledged that this alternative is expensive at present but will become competitive in a few years.

Another challenge for unconventional renewable energies is that they depend on the availability of resources such as sun or wind.

“The thermal matrix generates the reliability required for the implementation of unconventional renewable energies,” Tebsa’s Luis Miguel Fernandez said.

Fernandez said that there are warning signs of delays in awarded projects that could affect the scheduled energy supply.

“It is fundamental to guarantee the availability and expansion of assured energy that the country requires,” the expert said.

Experts said that the support of thermal generation is necessary, but this is not the only alternative for the system to have reliability.

GEB’s Juan Ricardo Ortega said that natural gas will be important for this process, and this is because it is dispatchable and clean.

“It is indisputable that natural gas is important for competitiveness,” Ortega said.

AES Colombia’s Federico Echavarría said that the government took the first step to drive the energy transformation, but private companies must take the next step.

“The 2019 auction and this year’s auction were the spark needed to take the first step. The second must come from the companies,” Echavarría said.

Bottom-Line: Colombia is beginning the process of energy transformation, and the country must face many challenges along the way.

Authorities must work together with the private sector and communities to successfully advance in this process.

One of the main obstacles to progress in the awarded projects has been the social issue, and the private sector needs more support from the authorities on this important issue.
