Hotel pioneer Johannes Badrutt admires an electric lighting system at the Paris World Exhibition. He is so fascinated by it that he puts a small water turbine into operation the same year in St. Moritz to lighting up the dining room of the Kulm Hotel - the first one in Switzerland.

Tourists get used to the benefits of electricity. To ensure the power supply during winter, Johannes Badrutt decides to use the flowing water of the river Inn. For this purpose, he builds a new power plant at the exit of the Inn gorge.

Caspar Badrutt, son of Johannes Badrutt, and Alfred Robbi, the mayor of St. Moritz, set up the first corporation for electric lighting - the founding of the first electricity plant in Switzerland. At the same time, construction gets under way for another centre slightly above the Kulm plant, in the Inn gorge.

The municipality of St. Moritz decides to build an electric tramway between St. Moritz Dorf and St. Moritz Bad. The tramway is 1,700 metres long and is supplied with DC power from the upper Charnadüra plant.

The municipality of St. Moritz exercises its right to repurchase and founds the Elektrizitätswerk St. Moritz on 1 April 1913, as a subsidiary enterprise – a form of organisation that still exists today.

The Elektrizitätswerk St. Moritz builds the new Islas power plant, which has a license covering a period of 60 years. The centre replaces the two existing plants in the Charnadüra gorge.

Construction work for the water reservoir in Lake Sils and Lake Silvaplana increases winter production in 1947/48 from previously 80,000 kWh to 400'000 to 450'000 kWh.

In response to the rising energy consumption, the Elektrizitätswerk St. Moritz builds the new Islas substation. It begins to operate in 1962, reducing the demand for foreign energy.

In order to meet the demand for technical services, St. Moritz Energie inaugurates the new "Punt da Piz" head office, which unites all the infrastructure previously scattered throughout St. Moritz and Celerina under one roof.

In order to meet the growing demand and to guarantee the smooth running of the World Ski Championships, St. Moritz Energie buils a second substation in St. Moritz-Bad with an installed capacity of 20 MVA

On 2 November, the keys are handed over for the new administration building in Punt da Piz, which is attached directly to the operation centre. Finally, the whole operation is under one roof.

After two years of preparation, the new grid control centre opens its doors, on 29 February 1992. The centre provides round-the-clock monitoring and, if necessary, remote intervention, even in isolated stations.

The Elektrizitätswerk St. Moritz extends its supply area, taking over all plant components of the Bündner Kraftwerke that are located within St. Moritz.

The Islas power plant is renovated and updated with the latest technology. Three Francis turbines increase the annual production, enabling production of approximately 20 percent of the electricity consumption in St. Moritz and Celerina. Click here for the video.

The Elektrizitätswerk St. Moritz changes its name to St. Moritz Energie. The new company logo underlines its market positioning and regional roots.

St. Moritz Energie builds the new energy network St. Moritz Bad. Individual buildings, such as the new indoor swimming pool OVAVERVA, are connected to the district heating system. The heat from Lake St. Moritz and the waste heat from the Ludains Ice Arena serve as energy sources.

In 2016 St. Moritz Energie renovates the property on Via Signuria. Two new residential floors with eleven apartments, parts of the administration and customer reception are now more attractive and customer-friendly. Click here for the video.

55 years after its construction, St. Moritz Energie has completely renewed the Islas substation. In order to bring it up to date, it was taken off the grid for one and a half years. The official commissioning took place on 26 November 2018. Click here for the video.
