Duna y Huambos experienced challenges unforeseen in planning, such as the 85-day stoppage due to the pandemic and the works development under adverse weather conditions, which, despite being avoided in the initial planning, were incorporated in tendentiously avoidable phases of the project. In addition to these challenges, there was the project's inhospitable location (in Cajamarca Mountains, 2500 meters altitude). Despite the difficulties, CJR Renewables achieved the success of this project with the completion of the milestones foreseen in the agreed times. For the good development of the project, Duna y Huambos had a team of more than 100 people per day on the ground.
