Paper model of load profile data from Wiener Netze


The generation and consumption of electricity need to be in balance at all times. If, for instance, too much electrical energy is fed in, overloading occurs and the network breaks down. A control centre, known as the ‘load dispatcher’, regulates the balance between power plants and consumers.

Electricity consumption changes constantly: whether it’s public holidays in winter or weekdays in summer, no two days are ever the same. However, each day and each year has its own distinctive pattern of consumption. The trend in electricity consumption throughout the day is forecast based on historical data.

Before the advent of electronic data processing, a statistics sheet was compiled for each and every day and logged on paper by hand. Nowadays computer systems are used to calculate and control all these components. Human operators are there to monitor the system and intervene in the event of exceptional emergency situations.
