Colombia"s new long-term renewable energy auction is being launched in a markedly different context from its predecessors.
While in 2019 the market lacked sufficient contracts to support structured financing, today developers are negotiating bilateral power purchase agreements (PPAs) of up to 15 years under bankable conditions, enabling projects to reach financial close without necessarily relying on a state-backed mechanism.
The change in context responds to a clear signal: potential system tightness towards 2027 2028, amid delays in grid expansion and constraints in the allocation of connection points.
Against this backdrop, retailers and large consumers have begun securing supplies further in advance, thereby energising the bilateral market.
"Those auctions took place in a context in which there were not many long-term bilateral PPAs available in the market, explained Manuel Gómez Fajardo, an energy and regulatory expert.
The structural difference between that moment and the present redefines the role the new process must fulfil.
Today, the question is no longer whether the auction is necessary, but how it adapts to a more sophisticated ecosystem.
"There are now PPAs of between 12 and 15 years that were not previously being offered," Gómez Fajardo stated, having participated in the negotiation of more than a dozen recent contracts from both sides of the table.
This progress does not weaken the mechanism; it raises the standard.
If the market already offers contractual stability and sufficient tenors to structure project finance transactions, the auction will need to provide a tangible differential in terms of guarantees, risk profile or regulatory predictability.
The voluntary nature of the scheme introduces an inevitable competitive logic.
Generators and demand-side players will assess whether the process offers better conditions than those available through bilateral agreements.
"If this auction is competing with a product that already exists in the market, it has to provide something extremely attractive in order to be truly successful, the specialist warned.
Success will depend on whether the contractual design proves more efficient or secure than the alternatives currently available.
For banks, the analysis remains centred on revenue stability and the credit quality of the offtaker.
Contract duration, counterparty solvency and institutional consistency carry greater weight than the award channel itself.
In an environment where some retailers are facing financial tensions, the structure of guarantees becomes particularly relevant for international capital.
At this point, the auction can play a strategic role: standardising contracts, enhancing transparency and broadening access to demand backed by solid credit profiles, not as a substitute for the bilateral market, but as a complement that strengthens financial discipline.
Moreover, the process is taking place in a pre-election year with presidential elections scheduled for 31 May 2026 introducing an additional institutional variable.
Regulatory predictability and the independence of the regulator will be decisive factors in maintaining investor confidence.
Additionally, Gómez Fajardo stressed that the discussion regarding the relevance of the mechanism is not the central issue.
The real debate lies in whether the design is capable of responding to the market"s new reality.
With the energy transition underway and signs of tightness on the horizon, Colombia faces a different stage.
The auction no longer operates as the initial driver of renewable energy expansion, but rather as a fine-tuning instrument within a market that has matured rapidly and now demands contractual and financial sophistication.
