The 24,710 acre (100 square kilometres) concession area is located 14 miles (22.5 kilometres) southwest of Guatemala City.

Included in the concession is the El Ceibillo geothermal project which has nine existing geothermal wells of depths ranging from 560 to 2000 feet (170 to 610 meters) drilled during the 1990s, and a significant amount of geophysical and other technical data.

According to the company, six of the wells have measured reservoir temperatures in the range of 365 to 400°F (185 to 204°C).
