• The projects will be backed by fifteen-year power purchase agreements (PPAs).
• Cocales (140 MWp) and La Hulera (60 MWp) photovoltaic power stations will be the first in the country to incorporate battery storage systems.
• The company will reach 362 MW in operation in Guatemala, thus consolidating its leadership in photovoltaic technology.
La Coruña, 26 March 2026.- Ecoener has been awarded two 15 year power purchase agreements (PPAs) that will enable the construction of the Cocales (140 MWp) and La Hulera (60 MWp) plants, further strengthening its leadership in photovoltaic technology in the Central American country.
The PPAs contracts were secured in the largest power auction in Guatemala’s history. Commercial operation is scheduled to begin in 2028.
Both plants will be the first in Guatemala to incorporate battery storage systems. Cocales will have a BESS system with 20 MW of power and 80 MWh of storage capacity, while La Hulera will incorporate another system with 10 MW of power and 40 MWh of storage capacity.
“This contract award reaffirms the strength of Ecoener’s international position and our capacity to compete successfully in highly competitive environments. It is also a relevant stage in the incorporation of storage solutions that deliver greater operational efficiency and long-term value to the company, as well as stability to the electricity system,” as was pointed out by Luis de Valdivia, Chairman of Ecoener.
New expansion stage
With the commissioning of these plants, Ecoener will reach 362 MW in Guatemala, a key market in the company’s international growth strategy, which is focused on developing projects in regions with stable regulatory frameworks and high demand for new generation capacity.
Ecoener has entered a new expansion stage after achieving its largest increase in capacity in 2025, with 253 MW of new capacity in operation, amounting to 680 MW of total capacity. The goal is to continue expanding installed capacity, strengthen stable revenue and boost profitability. With the projects under construction, Ecoener’s total capacity reaches 815 MW.
International process
The contract was awarded following an international tender process in which 51 technical bids were received for approximately 4,700 MW of installed capacity under the Guatemalan Government’s Power Generation Expansion Plan, designed to meet the growth in domestic demand and boost the country’s energy independence.
