Etzelwerk

Etzelwerk AG, based in Einsiedeln, is a Swiss power plant company that produces traction current (16.7 Hz).

== History == An initial project to build a power station with a storage reservoir in the high valley east of Einsiedeln was proposed in the Schweizerische Bauzeitung newspaper in 1899. Developed by in collaboration with Maschinenfabrik Oerlikon (MFO), it aimed to capture unused hydropower at night for daytime use. Electricity was recognised as an easily transportable energy form that could enhance Switzerland's energy independence. In 1900, MFO secured concession agreements with the districts of Einsiedeln and Höfe. In 1902, the canton of Zurich expressed interest, and in 1904, it proposed to the Federal Council that the power plant electrify the SBB. However, a thorough examination, published in 1906, revealed that the concessions were insufficient for construction and could not be transferred to the SBB for legal reasons, leading to their expiration in October 1910.
