From April 14 to 21, 2026, the second expedition of the TransGreenland Electric Challenge took place in Qaleraliq.
This phase focused on testing the performance of the electric snowmobile system, with special attention to technical trials related to load capacity, energy use, and overall operational capabilities.
The tests were carried out along the margins of the Greenland Ice Cap in the Qaleraliq area. During this fieldwork, the team evaluated the performance of the solar panels and the wind generator used for energy supply. On average, the system was able to generate around 15 kW per day, reaching up to 20 kW on clear days and approximately 8 kW on cloudy conditions.
The technical team for this expedition was composed of:
- Ramón Larramendi, project leader and experienced polar explorer
- Aka Simonsen, Greenlandic guide specialist and key member of the Windsled team, contributing to field operations and expedition support in Greenland
- J.J. Simonsen, Greenlandic logistics coordinator with extensive experience in field logistics and operational support in Arctic environments.
- Juanma Viu, pilot, long-term expedition member, involved in Windsled projects since 2001 and participant in major Antarctic expeditions in 2003 and 2005
- Tomás Valles, electronics engineer, whose key contribution was essential for the development of the expedition
- Francesco Boncompagni, Greenland guide and member of the team in his first expedition.
This 2026 phase served as an important technical testing ground for the system, particularly in terms of energy production, logistics, and vehicle performance under real polar conditions.
The next major challenge will take place in April 2027, with a planned long-distance traverse of approximately 500 km, reaching halfway to Nuuk (around Paamiut) and returning, designed to further test the endurance and autonomy of the system.
