Watt d’Or last edition of an energy prize
The Watt d'Or 2026 marks the end of the road and at the same time makes it clear where Switzerland's energy future is heading. The focus is on sector coupling, alpine solar energy, electrified mobility and circular neighborhoods.
The Swiss Federal Office of Energy awarded the Watt d’Or for the nineteenth and final time on January 8, 2026. The prize has been awarded since 2007 as a non-endowed seal of quality for energy excellence. The aim was to make exceptional achievements in the energy sector visible and to attract business, politics and the public to innovative energy technologies. 55 applications were received for the 2026 edition, 17 projects made it to the final round, from which the jury, chaired by National Councillor Susanne Vincenz-Stauffacher, selected the four winning projects.
Gaznat Innovation Lab “GreenGas“
Gaznat’s Innovation Lab in Aigle, where the gas supply company is working with EPFL and start-ups to test technologies for sector coupling, decarbonization and seasonal storage on an industrial scale, won in the energy technologies category. The GreenGas concept combines CHP, photovoltaics, power-to-gas (electrolysis), hydrogen storage, CO₂ capture, methanation and Gaznat’s real gas network at the Aigle site, thus building a bridge from research to industrial application.
Endigo with alpine façade PV
Endigo Holding AG from Fiesch, which has installed an alpine façade solar system at its new company headquarters in Goms, received an award in the renewable energy category. The lightweight timber construction with slatted façade combines architectural quality with a PV solution that utilizes the existing alpine light and reflection potential and stands for endigo’s regionally anchored, nature-loving and future-oriented energy focus.
Electric tractor from Rigitrac
Rigitrac Traktorenbau AG from Küssnacht am Rigi received the award for energy-efficient mobility for the SKE 40 e-direct electric tractor, the first production-ready electric tractor with European type approval. The vehicle is emission-free, quiet, maneuverable and particularly energy-efficient, making it suitable for applications where exhaust fumes and noise are undesirable. For example, in municipal maintenance, in vegetable tunnels or at indoor sports events.
Buildings and space
The Hobelwerk site in Oberwinterthur, which was developed by the building cooperative “mehr als wohnen”, Lemon Consult AG and the Low-Tech Lab together with other partners, received an award in the buildings and space category. The district impresses with its timber construction, the use of recycled materials, intelligent energy systems, an innovative ventilation concept, climate-oriented architecture and social diversity and is regarded as a model for forward-looking, non-profit housing construction in Switzerland.
