Next Kraftwerke GmbH is tackling the most common criticism made of renewable energy sources, the risk of fluctuations in the electricity grid owing to changeable weather effects. The electricity grid is stabilised with the renewables with the aid of a large scale virtual power plant. This is done by making controllable plants (biogas, CHP plants etc.) produce more or less electricity when an imbalance in the electricity grids is likely.

SAE IT telecontrol technology is used to monitor the Haunsberg well installation, which acts to geologically stabilise the land. Within the catchment area of this installation, there are a local rail line, the B156 road and a natural gas pipeline. The wells are used to achieve a controlled reduction in groundwater to below 400 m above sea level, which is critical in this region.

In the Salzburg local rail network approximately 52 sets of points are equipped with points heating systems. For each set of points, two heating rods are used, which are up to 5 m long and emit heat at a temperature of 65 – 75 °C. Power is supplied via the public 50 Hz network. The heat output of the electric points heating systems is 3.6 kW (2 x 1.8 kW). The points heating system is controlled with net-line FW-50 telecontrol systems, which have a codeIT soft PLC (IEC 61131-3).
