The 100-year-old Gelmer Hut of the Swiss Alpine Club (SAC) was renovated and adapted to today’s needs between mid-2025 and spring 2026. Through its commitment, Transitgas AG is strengthening the hut’s sustainable energy supply at 2,412 metres above sea level.

The Gelmer Hut is located in the heart of the mountain landscape of the Grimsel region, nestled above the upper Dietcher and 7.5 km from the municipality of Guttannen – the last village before the Grimsel Pass summit. The Transitgas transport system also runs through this area.

In 2025, Transitgas AG is supporting the energy renovation of the Gelmer Hut. The project, led by the SAC Brugg Section, includes the renewal, regulation, and control of the small hydropower plant as part of the overall refurbishment. The plant ensures the hut’s electricity supply.

Construction activities under these conditions had to be carefully planned and budgeted. The SAC Brugg Section committed to this project through a long-term process, with numerous volunteers contributing essential work. At the same time, the project team relies on professional implementation by specialized experts. In addition to funding from Transitgas AG, the SAC Brugg Section is also supported by other organizations.

Transitgas AG is supporting the renovation project with financial backing, as it aligns perfectly—both thematically and geographically—with its sustainability funding strategy. The combination of technical innovation, regional roots, personal commitment, and ecological impact played a key role in the project’s selection. The challenging renovation in the alpine area was completed smoothly and on schedule. The opening ceremony took place on 27 June 2026, with Dani Neiger and Ennio Sinigaglia from Transitgas AG also in attendance.
