Thurplus

Beyond the standard kWh billing model, Thurplus also offers SolarPlus (a freely chosen solar share of your power consumption), SolarInvest (participation in solar projects) and EigenverbrauchPlus for buildings with multiple parties. That makes the offer more flexible than a plain contracting deal.

As a nonprofit utility, the company focuses on the Frauenfeld region and the canton of Thurgau. For properties outside that area, it's worth checking coverage before making an inquiry.
