Concepts for voltage and capacity management

Siemens offers state-of-the-art and economic solutions to efficiently manage voltage increase and overload situations throughout all voltage levels.

Grids are increasingly affected by varying load and feed-in conditions with significant fluctuations in operating voltage. Operators benefit from Siemens’ intelligent design concept for managing voltage and capacity in power grids – without having to invest in costly grid expansions. 


The solutions utilize various approaches to voltage control, depending on the given structures and conditions on-site and in the field. Customized solutions help to achieve maximum efficiency in the entire medium-voltage grid. They also ensure regional and local voltage and grid stability right down to the low-voltage range.


Benefits for grid operators

  • Minimization of new investment through efficient use of existing structures
  • Improved capacity utilization of the medium- and low-voltage grids
  • Optimized use of the voltage range with just a few distributed measuring points
  • Regional communication without great cost
  • Automatic monitoring of grid status for operation and planning
