per kW of peak power at the feed-in point.
In all industries in which energy efficiency plays a crucial role, the software program SIMATIC powerrate from Siemens can reduce energy costs by preventing power peaks. No separate, dedicated system environment is needed thanks to SIMATIC powerrate’s complete integration in the SCADA system SIMATIC WinCC.
Power supply limits which are contractually agreed with power providers are an instrument for limiting energy costs. Power providers generally offer reduced rates for constant, calculable power values. Plant operators unable to adhere to their agreed power limits face significantly higher procurement prices, surcharges or even penalties.
The load management feature of SIMATIC powerrate carries out cyclic trend calculations in order to issue warnings and alarms if violation of the limit is likely and to switch off loads in accordance with the given configuration if required. This enables plant operators to avoid penalty payments and lower their energy costs.
To prevent unnecessary switching operations, numerous parameters are available for adapting the load management to the current process conditions – and all this can be done easily and conveniently via faceplates. For loads that are distributed over different PLCs, SIMATIC powerrate contains appropriate PLC-to-PLC communication blocks which can be used to integrate these loads into the load management system.
SIMATIC powerrate also norms, visualizes and archives the average energy consumption and power values: On a plant-wide level, SIMATIC powerrate for the SIMATIC WinCC process visualization system delivers an impressive performance. The software records all energy-related consumption data of the plant, correlates them to the specific electrical loads, visualizes them clearly, and saves them in the archive.

In countless industries and business sectors, SIMATIC powerrate has proven how it transparently identifies, visualizes and documents energy flows and consumption and reduces load peaks.
The Hartmann Gruppe, a leading provider of medical and hygiene products, uses SIMATIC powerrate to identify savings potential in their production.
They succeeded in reducing the peak load at their forklift charging stations and in their recycling operations by 10%.
“Since we now have a very clear picture of the development of our consumption over time, we have a significantly better basis for future negotiations with our suppliers,” notes Christian Koch, Technical Director at Hartmann AG in Herbrechtingen, Germany.
This leading LED manufacturer uses the energy management system SIMATIC powerrate as part of a holistic, end-to-end energy concept.
The software program helps the company to reduce their relatively high energy consumption for LED fabrication and power peaks.
Osram Opto Semiconductors has succeeded in lowering its peak power by up to 800 kW and, by integrating other electrical loads, achieved further optimizations.
Since the automotive industry is required to reduce energy consumption and CO2 emissions across the entire manufacturing chain, it often favors suppliers who can demonstrate that they also are saving energy.
This market leader in motor vehicle window frames therefore visualizes the energy data of all 100 machinery units at its plant using SIMATIC powerrate in WinCC.
In addition to displaying measured values, documenting data histories and identifying trends, the software is used at the plant in particular to prevent peak consumption.
