The National Electric Energy Company of Honduras (Empresa Nacional de Energia Electrica / ENEE) has published a tender for the “Technology Selection and Plant Development for the Namasigüe Geothermal Project.”

Proposals will the tender will be accepted only until 21 January 2025. More details and links to relevant documents can be accessed via this link.

The scope for the project will include:

• Selection of the best applicable technology based on existing results, considering that the system is of low and medium enthalpy based on applied geothermometers
• Schematic and modeling of the proposed plant, considering social and environmental variables applicable to the project.

The Namasigüe geothermal project is located between the municipalities of Namasigüe and El Triunfo, in the department of Choluteca. This project has undergone technical and financial evaluation for the generation of electricity using geothjermal resources, in addition to social and environmental work that has allowed the sustainability of the activities done to prepare a Geothermal Conceptual Model.

The hydrothermal system is linked to a fault system associated with the Guayape fault, with a natural anomalous heat gradient. Technical variables have been identified that allow the probabilistic evaluation of the resource.

Honduras currently has one operational geothermal power plant, the 35-MW Platanares power plant that was inaugurated in 2018. In 2020 Ormat indicated plans of expanding the capacity of Platanares by 20 MW.
