Additional geothermal wells on Ecuador radar

Ecuador's power generation expansion plans envision the installation of 4.7GW through 2025, and although the bulk of new capacity will be hydro, authorities forecast that geothermal will contribute 150MW.

BNamericas is tracking five early stage geothermal projects in the country: Chacana (318MW), Chalupas (283MW), Tufiño-Chiles-Cerro Negro (138MW, a joint project with Colombia), Chachimbiro (80MW) and Chalpatán (51MW).

Chachimbiro is the farthest advanced, where drilling of Ecuador's first geothermal well was completed a year ago to a depth of 1,978m, under a cooperation agreement with the Japan International Cooperation Agency.

In March, well tests encountered temperatures greater than 200°C and permeable rock.

The next step is the development of the field to define the reservoir's extension, and to this end, state power generation holding company Celec has launched prequalification to help draft contracting mechanisms to drill new wells.

Documents are due by December 13 and results are expected later that month, according to procurement information.

Chachimbiro is in Imbabura province at around 3,500m above sea level.
