  • Production processes in energy-intensive industries, e.g. chemicals and pharmaceuticals
  • Plants older than 5 years
  • Plants with high emission values
  • Plants with high consumption of heating agent, e.g. heating steam
  • Plants with high consumption of cooling agent, e.g. cooling brine
  • Plants frequently operated at partial load
  • Plants without thermal integration (use of heat sources and sinks)
  • Plants with large, unused heat sources, e.g. hot exhaust gases


Increasing cost pressures, strong competition, stricter statutory directives, and high energy prices are great challenges for energy-intensive industries such as chemicals and pharmaceuticals. Plants can only remain economical in the future if the owners continuously modify them in accordance with the current demands.

With its Premium Service "Energy study", Siemens offers you holistic solutions with associated process optimization options for reducing operating costs. The Premium Service "Energy study" has a modular structure. The range of services covers evaluation of the plant's energy requirements, the preparation of a feasibility study for effective energy-saving measures, up to specific implementation of the determined measures in the plant.


The Premium Service "Energy study" consists of three modules which build upon each other and which can be ordered individually:

Module 1:
Determination of energy saving potential through analysis by experts
  • One-day workshop to analyze the energy saving potential for a production process
  • Participants: Siemens experts and representatives of the client with profound knowledge of the process
  • Submission of a catalog of questions and a list of required data to the client for preparation of the workshop
  • Consideration of plant criteria such as plant size, mode of operation, significant heating and cooling media, existing thermal integration
  • Discussion of production process and possibly visiting of the existing production plant
  • Result: Workshop documentation with evaluation of the energy saving potential, and specific recommendations for further actions
Module 2:
Preparation of a feasibility study (energy study)
  • Feasibility study for detailed, project-based process analysis with qualitative and quantitative evaluation of the energy saving potential
  • Goals: Detailed overview of energy consumption in the investigated process; suggestions and assessments of possible energy saving measures
  • Participants: Siemens experts and representatives of the client
  • Generation of an energy balance based on the results of Module 1 or information provided by the client such as:
    • Quantity balance
    • Plant/process description as well as flowcharts and overviews of the energy/media consumptions (e.g. from the design documents)
    • Clear representation of the production process (PFD/PID)
    • Overview of the plant's energy consumption referred to the various media (per month for a period of one year)
    • Consumption costs at the site for the various media (steam, electricity etc.)
  • Result: Documentation of the process-specific energy and quantity balances, as well as suggestions in order of priority for implementation of energy saving measures in the form of a feasibility study
Module 3:
Implementation of the produced feasibility study
  • Implementation of the knowledge gained in Modules 1 and 2
  • Detailed processing and implementation of the energy saving measures assigned a high priority
  • Content is the subject of an individual agreement between client and contractor
  • Basis for the individual agreement is a project-specific quotation provided by Siemens as the contractor
  • Inquiries for production of a quotation should be directed to the address specified under "Further information"

The modules of the Premium Service "Energy study" do not include any traveling expenses. Traveling expenses from the Hoechst Industrial Estate, Frankfurt am Main, Germany, will be invoiced separately.


  • Industrial plant optimization for reduction of energy consumption and operating costs
  • Reduction in emissions and improved conformity with statutory directives
  • Increase in plant availability through process improvements and modifications
  • Development of new, innovative processes with significantly lower energy consumption
  • Vendor-independent design of equipment and plant components when converting
  • Determination of investment costs and amortization times for individual projects
  • Planning and construction of plants from a full-line supplier

These advantages are partially dependent on the plant size and the production capacity. The difference they make primarily depends on the industrial characteristic of the process.
