Guatemala"s fifth Power Generation Expansion process (PEG-5) received bids totalling approximately 4,700 MW of capacity, compared to the 1,400 MW required under the tender, with 51 companies participating.
Although the final report is still being prepared, industry sources estimate that more than 2,000 MW of the total submitted correspond to solar PV projects, both with and without energy storage.
This reflects the strong presence of renewable energy technologies in a procurement round that also allows thermal generation offers.
Total estimated investment across all technologies exceeds USD 3.5 billion.
The high volume of capacity offered makes this the most competitive procurement process in Guatemala in recent decades, as the submitted capacity significantly surpassed previous contracting rounds in the country.
What comes next?The economic evaluation of bids has been scheduled for 25 March 2026 through a reverse auction mechanism.
Final awards are set for 16 April 2026, and contracts must be signed within a maximum period of three months thereafter.
The awarded power purchase agreements (PPAs) will have a 15-year term, with supply beginning between 2030 and 2033.
The auction design prioritised efficiency and competition, creating strong price pressure that could translate into improved conditions for regulated consumers and greater cost discipline in awarded generation projects.

This led to the issuance of four addenda to the bidding documents and five information sessions, including a simulation of the reverse auction mechanism.
According to the official communication, the tender "has been conducted under the highest standards of transparency, participation and technical rigour", reinforcing perceptions of institutional predictability in Guatemala"s power sector.
This outcome takes place in a context of review of the national electricity infrastructure, following setbacks recorded in the PET-3 transmission tender.
As a result, the country is preparing its relaunch along with new grid expansion calls in 2026.
Coordination between generation expansion and transmission reinforcement will be decisive in integrating the projected new capacity and avoiding medium-term operational constraints.
Aligning renewable energy growth, firm capacity, and grid investment will be essential to ensure system reliability and support continued investment in solar PV, energy storage and other clean energy technologies.
