Solar energy

Solar energy is transmitted by the sun in the form of light and heat. It can be used, for example, to generate electricity through photovoltaic panels.

A photovoltaic solar panel produces electricity when the sun shines. This electricity can be used in the building where the installation is located (self-consumption) or fed into the grid. Not to be confused with a thermal solar panel that heats water in a heating circuit.

Hydraulic energy

Hydraulic energy uses the force given to water as it flows through the earth's gravity. There are 2 types of hydraulic power plants:

  • A run-of-river power plant uses the energy of a river. A dam across the stream channels the water through turbines coupled to a generator that produces electricity. Because of the river's gentle slope, it is primarily the amount of water that determines the power and energy produced.
  • A storage power plant stores water in an artificial lake located at high altitude. This water flows as needed through a steeply sloping penstock to be turbined in a power plant located on the plain. The power and energy produced depend on the storage capacity of the lake, the diameter of the pipe and the difference in altitude between the storage lake and the power plant.

Product mix

Electrical energy comes from different sources such as solar, hydraulic, wind, etc. The product mix refers to the share of each of these energy sources in the current supplied to the customer. Electricity flowing on the grid cannot be characterized according to its source of production. It has no colour, odour or any other attribute that can be used to determine its origin. On the other hand, the various electricity suppliers indicate the source of production for each kWh purchased in Yverdon-les-Bains Énergies. Each of these kWh is then allocated to the product supplied to the customer in accordance with the shares indicated in the description of each product.

Electricity network

Yverdon-les-Bains Énergies' electricity network provides an annual supply of around 120 million kWh to the 27,000 inhabitants and businesses of Yverdon-les-Bains. The network of the City of Yverdon-les-Bains consists of 186 km of low-voltage cables, 70 km of medium-voltage cables and 96 km of public lighting cables. Two 40 kV / 20 kV transformer stations and around 80 low-voltage transformer stations make the link. Electric power is supplied at a voltage of 230 / 400 V, identical to that of European countries, and at a frequency of 50 / HZ (50 cycles per second).

Duty Service

The electrical duty service intervenes 24 hours a day for all faults occurring on the public grid. Outside opening hours, telephone +41 24 423 65 26.
