ISO 50001

Make energy transparent – and rewarded

ISO 50001 is a worldwide standard for in-house energy management systems. The standard describes all the requirements for an energy management system, from establishment and implementation to maintenance to optimization. We provide step-by-step support for implementing an energy management system according to ISO 50001 – and we can show you how you can even benefit from state subsidies and tax advantages with standardized certification.

Your opportunity: ISO 50001

There are many good reasons for implementing a corporate energy management system, which is extremely important for creating transparent energy consumption. The result is energy-saving measures and reduced energy costs. An energy management system also significantly increases your competitiveness when the identified savings potential is consistently exploited. We can support you throughout the entire process and to successful certification. By consulting our experts right from the start, you can be sure that the certification process is conducted in a structured and effective way. That’s how we ensure that efficient energy management pays off for you.

Our contribution: SIMATIC Energy Management software

Get all the energy data you need from your production process thanks to our SIMATIC Energy Suite energy management solution: it provides end-to-end transparency of all energy flows. The TIA Portal enables the ease of engineering  and you can benefit as well of an uniform platform for automation and energy management – including across locations. The recorded energy data can be seamlessly expanded to form a multisite energy management system thanks to the end-to-end connection to SIMATIC Energy Manager PRO or the cloud-based Service Energy Analytics. We offer you a comprehensive ISO 50001-certified product and solution portfolio with additional SIMATIC Energy Management software – from the management to the field level.

EN 50598

Meeting efficiency targets – with a system

Industry accounts for a considerable share of an economy's energy consumption. One of the biggest factors here is electrically driven systems: In industrial plants, electric motors account for almost 70% of the electricity demand. Not only that: the energy costs of an electric drive account for up to 97% of the total life cycle costs. Electric drive systems therefore offer enormous potential for savings. However, measures focusing on the motor alone will not be enough to achieve the Europe-wide target of reducing CO₂ emissions by at least 55% by 2030 compared with 1990. This requires a holistic system approach: Energy savings of up to 60% can be achieved for the entire drivetrain by combining measures such as increasing the efficiency of the motor itself, variable-speed operation through the use of frequency converters, and optimization through integrated digital solutions.

High motor efficiency is the basis – the new EU Regulation 1781/2019

A new EU regulation on the energy efficiency of electric motors has been in force since July 1, 2021. To determine the energy efficiency of a motor, globally uniform efficiency classes and a series of energy efficiency regulations were created in the past, which were summarized under the name Ecodesign or ErP Directive. The efficiency classifications are based on the international standard IEC/EN 60034-30-1, which defines classes IE0 to IE4 for electric motors. The previous Regulation 640/2009/EC has been replaced by the new Regulation (EU) 1781/2019. The new regulation defines minimum requirements for motors, so-called MEPS (Minimum Efficiency Performance Standards). For the first time, it also includes a clear regulation for frequency converters and an IE4 efficiency class requirement for electric motors. Specifically, efficiency class IE4 is specified for motors from 75 – 200 kW as of July 1, 2023. Low-voltage motors of the SIMOTICS family already offer IE4 from 2.2 to 1000 kW.

The key to maximum energy efficiency lies in the system – the European ecodesign standard IEC 61800-9

The European standard EN 50598 has been transposed into the international standard IEC 61800-9. This consists of two parts and specifies ecodesign requirements for drive systems, motor starters, power electronics and their driven equipment. Part 2 of the ecodesign standard, IEC 61800-9-2, moves the focus away from individual components to the system. Since 2015, IEC 61800-9-2 has defined the requirements for drive systems in an electrically driven machine. This means that all products that convert electrical energy to a significant extent must be evaluated in terms of their efficiency or losses. The second part of IEC 61800-9-2 is particularly relevant for determining energy efficiency. It shows how losses of drive and motor systems are to be determined by the manufacturer. This gives users the opportunity to compare products in terms of their energy efficiency.

Federal government financing program

It pays to invest

In order to make it easier for companies to invest in energy-efficient processes, the German Federal Ministry of Economic Affairs and Energy has refocused its financial support programs in the field of energy efficiency. The investment program entitled “Energy Efficiency and Process Heat from Renewable Energies in Industry – Subsidies and Loans” standardizes the previous financial support options.

The objective: to reduce primary energy consumption by 50% of 2008 figures by 2050.

In addition to the expansion of new electricity-generating capacities based on renewable energies, the energy revolution focuses on reducing energy consumption by increasing energy efficiency. To this end, the Federal Ministry of Economic Affairs and Energy has published new financing guidelines with the intention of simplifying the existing financial support models. Instead of dividing the units to be subsidized into different programs with different requirements, as was previously the case, the investment program for energy efficiency and process heat from renewable energies in industry separates the subsidy options into four modules: general-purpose technologies; process heat from renewable energies; instrumentation and control, sensor technology, and energy management software; and energy-related optimization of plants and processes. Financial support can be applied for in the form of a subsidy or loan. One prerequisite, however, is that companies have ISO 50001 or equivalent certification, or that the appropriate certification process has been started.
