Energy Supply and Power Quality


Primetals Technologies offers safe and reliable power distribution and power quality solutions, tailored to your technological process needs and utility supply requirements.

A well designed and adequate power supply is a fundamental requirement for all works in any steel plant. The planning phase of the power distribution system should be guided, first and foremost by process knowledge. We create a solid design basis for your distribution solutions by using our extensive know-how in the fields of high, medium, and low-voltage systems, along with the specific needs of your technological processes, design philosophies and maintenance requirements. We provide safe energy supply throughout the plant by meeting and exceeding industry leading safety standards and codes. Our solutions are tailor-made to provide maximum reliability and availability by using rugged power distribution configurations.

Safety is of utmost importance in power system design. Our PE licensed engineering team establishes compliance with local codes and standards to ensure safety of the personnel and property from hazards arising from the use of electricity


The selection of system arrangements has a profound impact on reliability and maintainability of the system. Commonly used topologies are:

  • Radial
  • Loop
  • Ring Bus
  • Composite

Minimum initial investment and maintenance cost

Primetals Technologies works with customers to provide cost optimized and effective electrical systems. Although equipment and installation costs are primary contributors to initial investments, in large complex systems, operation and maintenance costs become critical.

Power Quality solutions with scope from design to complete turn-key installation.


Filters are used to provide power factor correction and/or harmonic mitigation. Typical configurations are:

  • Active or Static Filters
  • Outdoor installation or indoor installation
  • Air core reactors or Iron Core
  • Filter yards or completely enclosed filter installation

Static VAr Compensators (SVC)

SVCs are placed near high and rapidly varying loads, such as arc furnaces, where they can provide voltage stabilization, reactive power control, power factor improvement, flicker mitigation and total harmonic distortion reduction.

Typical ratings of SVCs in the metals industry:

  • 11kV to 35kV
  • 25 MVAr to 250 MVAr

Static Synchronous Compensators (STATCOM)

STATCOMs are Voltage Source Converter (VSC) based systems. They, like SVCs, provide voltage stabilization, reactive power control, power factor improvement, flicker mitigation and total harmonic distortion reduction with the following additional features and benefits:

  • Higher flicker reduction factor
  • Lesser harmonic filter requirement
  • Allows for loads to be fed from weaker transmission systems
  • Smaller footprint allows for real estate savings and lower installation costs

Power Monitoring, Control and Automation

Integrated approach

Supervisory Control and Data Acquisition (SCADA) solutions offered by Primetals Technologies allow energy management, power monitoring, and process automation systems to combine into a single system.

Key Benefits:

  • Seamless data exchange between process and power automation systems
  • Increased data availability for analytics and big data processing

Cost efficient and robust

Our system is completely vendor agnostic and is compatible with modern protection and metering devices. All major communications protocols such as IEC61850, MODBUS, PROFIBUS, DNP3 are supported for data exchange.

Time synchronization and Trending

Trending, storage and retrieval of important values such as alarms, currents, voltages etc. are easily configurable as per operator requirements.

All devices are time synchronized to a central clock and all alarms are time stamped. This allows for quick event diagnosis and fault analysis.

Scalable Systems

Primetals Technologies’ SCADA solutions are scalable from a single device to thousands of devices or equipment. With such flexibility and scalability, we are able to provide solutions tailored to very small or very large systems, thereby satisfying any and all customer needs.
