Guatemala's PEG-5-2025 tender is progressing with a result that redefines the expansion of the electrical system: of the 1505 MW awarded in 57 projects , 1102 MW correspond to renewable technologies , which is equivalent to 73% of the total and marks a clear predominance of clean sources.
The summary prepared by MELECSA confirms this structural change, where thermal technologies are relegated to a complementary role with coal/biomass (175 MW) , petroleum coke (135 MW) and gas/bunker (93 MW) .
Within the renewable energy sector, solar energy with batteries is positioned as the dominant technology with 713 MW , representing approximately 47% of the total awarded and more than 60% of the renewable segment .
This volume far exceeds other technologies such as hydroelectric ( 140 MW ) and hybrid configurations such as hydro + solar (98 MW) , demonstrating a change in system planning, where the management of intermittency becomes a central factor.
Even other combinations such as coke + solar (135 MW) lag behind in participation, consolidating the leadership of solar with batteries as the most competitive option in the process.
This behavior occurs in a context of high competition: the auction lasted 14 hours under a descending round scheme and registered 57 economic offers , with an average mononomic price of 101.09 USD/MWh , resulting from the balance between power and energy offered.
Leading companies and rollout towards 2030The process also shows strong participation from private companies , mainly in renewable projects and storage solutions.
These companies are leading the development of new capacity and consolidating Guatemala's position as an attractive market for investments in generation, especially in hybrid technologies.
In contractual terms, DCCs predominate (666 MW in 35 contracts) , followed by OCs (753 MW in 13 contracts) and SEs (85 MW in 9 contracts) , which adds diversity to the supply scheme.
The commissioning schedule shows a strong concentration in the short term: 1058 MW will begin operating in 2030 , while the remainder will be distributed in 2031 (197 MW) , 2032 (140 MW) and 2033 (110 MW) .
Taken together, the results of PEG-5 consolidate a clear trend: Guatemala is moving towards a matrix dominated by renewable energies , where solar with storage leads in awarded capacity and is positioned as the key technology for the expansion of the electrical system in the coming years .
