Guatemala is at a turning point in renewable energy, but the challenge is no longer solely about allocating new capacity. Now, the central question is: Can the electrical infrastructure, regulations, and public institutions keep pace with the growing demand?
That was the central theme that Armando Martínez , general manager of the National Electrification Institute (INDE), put on the table during his participation in the Future Energy Summit (FES) Guatemala.
“It’s clear we have shortcomings from the perspective of the bottlenecks that are occurring mainly in transmission. Today, connecting supply with demand is a challenge,” the executive acknowledged.
The statement comes at a particularly sensitive time for the country. Guatemala has just awarded 1258 MW through 57 projects in the PEG-5 tender , with a 73% renewable share and a leading role for solar with storage systems.
Within that volume, clean technologies account for approximately 918 MW , while solar with BESS adds up to 671 MW and represents more than 53% of the total awardable.
The result positions the country as one of the most dynamic markets in Central America for renewable generation and storage, but it also exposes a structural tension: the grid must be ready to absorb, transport, and manage this new supply.
According to the general manager of INDE, the transmission infrastructure must adopt new technologies, gain flexibility, and respond more quickly to a demand that no longer waits for traditional planning times.
“It is clear that the speed at which demand is setting the pace should put us on alert,” he said.
He added that the challenge lies not only in looking at long-term plans, but also in adapting short-term solutions to the existing infrastructure.
The bottleneck is already having a concrete impact
The warning doesn't come out of nowhere. The private sector itself has already raised concerns about the risk of operational restrictions if network expansion isn't accelerated.
In the context of the debate opened after PEG-5, the industry warned that up to 800 MW of solar power could be limited if Guatemala does not resolve its transmission needs in time.
This data gives another dimension to INDE's argument: the renewable boom can become a historic opportunity, but also an additional pressure on an infrastructure that is already showing signs of saturation.
“This means that our infrastructure, mainly in transmission, has to embrace the challenge of being flexible, adopting these new technologies, adapting to the speed, and starting to provide the solution that is so eagerly awaited,” Martínez said.
The goal, he explained, is not only to solve Guatemala's local problem, but also to contribute to a regional discussion. According to the general manager of INDE, the challenges facing the country are mirrored throughout Central America, where electrical integration demands more coordinated and standardized solutions.
“The task we have is quite challenging in that regard,” he summarized.
From the failure of PET-3 to the PET-4 trial
The discussion about transmission was also complicated by a recent precedent: the PET-3 tender, which failed to be successfully completed and ended without any bids.
That episode taught a lesson for the Guatemalan market. If the risk of permits, easements, and land management falls almost exclusively on the private sector, projects become less profitable and more difficult to execute.
The Government has already indicated that the eventual PEG-6 must be accompanied by PET-4, a new transmission tender that will seek to unlock critical infrastructure for the system.
In this scenario, INDE's position carries significant weight. The entity appears not only as a technical actor, but also as an institutional player called upon to accelerate processes, prioritize tasks, and signal confidence to private capital.
Martínez expressed it with a self-criticism that is unusual for a state representative.

“We need to debureaucratize the concept of network access, which we actually have a high percentage of, and ensure that we are not a delaying factor in the execution of projects, but rather a driving force that allows this to be realized as soon as possible,” he stated.
INDE seeks to be an ally of the private sector
The general manager of INDE also stressed that the institution must get closer to market agents in order to translate their needs into public policies with greater stability, legal certainty and bankability.
From his perspective, the state's role cannot be limited to managing processes . It must contribute to making projects feasible.
“We need to build the necessary trust in the sector so that they see us as an ally,” he said.
Along those lines, he raised the need for joint work between banks, private initiatives and state-owned companies to expedite projects that are necessary to address the identified bottlenecks.
This is a significant signal. The introduction of batteries, the growth of solar power, and the need for new transmission infrastructure necessitate combining private investment with efficient public management.
Without that coordination, the risk is that the allocated capacity will advance faster than the infrastructure needed to integrate it.
Rural electrification, microgrids and storage
INDE also views the challenge from another scale: rural electrification.
Martínez explained that the institution works on two fronts. On one hand, connecting large generation projects with demand through the transmission system. On the other hand, providing distributed solutions for households that still require energy access.
As he explained, INDE has a goal of between 9,000 and 10,000 households for this year, while for next year it plans to reach close to 20,000 individual solutions linked to renewable energy.
These solutions will include storage and microgrid schemes, with the aim of bringing the quality of service closer to that of a network-connected user.
“We are thinking about both dimensions: not only connecting supply and demand through that macro generation, but also that micro solution that has to be designed in a way that is prepared to provide answers in the short term,” he explained.
This point adds a social dimension to the debate. The discussion about renewables in Guatemala is not limited to large solar projects with batteries, but also encompasses the system's capacity to deliver energy to areas where the grid has not yet reached or does not offer sufficient conditions.
2030 demands realism
Towards the end of his speech, Martínez was asked about a key word to define the priority heading towards 2030.
His response did not point to a specific technology, capacity goal, or reform.
“I would contribute the idea of being aware of the situation we are in so that we can face it with the challenges it entails. Being aware of the reality we have,” he said.
The phrase summarizes the tone of his participation in FES Guatemala: the country has a concrete renewable opportunity, but also a structural debt in infrastructure, permits and institutional coordination.
The PEG-5 program opened a new chapter for clean energy generation and storage. Now, the challenge will be to demonstrate that the government, the National Institute of Electrification (INDE), banks, and private companies can move at the speed the system demands.
Because the real test for Guatemala will not only be awarding megawatts, but ensuring that those projects are connected, operational, and meet demand without getting caught in the bureaucratic web.
