Energy (data) management – or why ISO 50001 isn't everything

Time and again we are confronted with the question: "You sell energy management systems, don't you?" The answer is always the same: "Yes and no." Our product portfolio includes components, software, and solutions for recording and analyzing energy-related data and thus forms the basis for a range of possible tasks and objectives, and therefore also for an energy management system.

ISO 50001

ISO 50001 is the standard that governs the introduction of an energy management system. The focus here is on the term "management system". Based on other management systems such as ISO 9001 or ISO 14001, this is a methodology for setting goals, implementing them systematically, and eliminating the factor of chance as far as possible. In this context, the term "goal" should be understood more along the lines of "the journey is the goal".

The PDCA or Plan-Do-Check-Act system is a CIP (continuous improvement process) that gradually examines processes and procedures for their optimization potential and defines measures and responsibilities as well as the necessary resources and time periods. The structure of ISO 50001 is similar to that of ISO 9001 or ISO 14001 and can therefore be easily integrated into existing management systems, which significantly reduces the effort required for implementation.

The word "check" contained in the PDCA process also immediately shows the reference to the topic of measurement data acquisition and evaluation, or in other words: Energy data management. Without measurement, no target/actual comparison, no benchmark is possible. Although ISO 50001 does not contain any clear specifications regarding the scope and frequency of energy measurements, practice shows that without a minimum of measurement technology for continuous recording, at least for all major consumers, potentials can only be determined to a limited extent and savings targets can therefore not be achieved comprehensively enough. Customers who have achieved their certification with a minimum of measurement effort recognize the benefits of more extensive measurement across as many consumers as possible during the ongoing PDCA process.

Our measuring systems are scalable and grow with the customer's requirements. Existing structures can be adopted just as easily as our measurement devices can be integrated into existing systems.

Who needs ISO 50001 anyway?

EEG (Renewable Energies Act) §40 ff. – EEG levy reduction

Under certain conditions, companies are entitled to apply for a reduction in the EEG levy:

  • Company must be in the manufacturing industry
  • Share of electricity costs at least 14% of gross value added
  • Annual consumption must be at least 1 GWh per site
  • From an annual consumption of 10 GWh, ISO 50001 certification is required to achieve the reduction

The regulation is intended to ensure the international competitiveness of energy-intensive companies. Due to the increase in the share of renewable energy producers, the EEG levy is likely to continue to rise sharply, which will indeed put energy-intensive companies at a significant competitive disadvantage. Despite all the half-truths that are spread in the media on this topic, practice shows that the lion's share of all companies that have applied for and received approval for the EEG reduction are actually energy-intensive companies and are in international competition. A much larger proportion of companies with a high electricity consumption of >1 GWh per year already fail to meet the 14% value-added hurdle in the approval process.

StromStG (Electricity Tax Act) §10 – Peak balancing

Companies in the manufacturing sector can benefit from peak balancing under certain conditions in accordance with §10 StromStG. The company may be exempted from or refunded the tax burden remaining after application of §9b StromStG. This "relief in special cases" (known as peak balancing) is only granted if the tax burden exceeds €1,000 in a given calendar year (deductible/basic amount). The amount of relief depends on the difference between the electricity tax, which exceeds the basic amount, and the (notional) relief resulting from the fact that pension insurance contributions have fallen since the introduction of the electricity tax (for general pension insurance from 20.3% before the introduction of the electricity tax to currently 18.9%; with an employer contribution of 50%, this meant a reduction of 0.7% for employers in 2013; the "difference"). A maximum of 90% of this difference will be waived, reimbursed, or refunded. This calculation formula means that companies with high electricity consumption and few employees (subject to pension insurance) benefit particularly from peak balancing.

Since 2013, proof of an ISO 50001-certified energy management system has been required for large companies in order to obtain the peak balancing scheme. For small and medium-sized enterprises (SMEs), an energy audit in accordance with DIN EN 16247-1 is sufficient.

From practical experience:

Managing Director F. to Operations Manager A.: "How much electricity do we actually use?" Operations Manager A.: "I'm not sure, but definitely a lot!" Managing Director F.: "Make sure that this changes!" Operations Manager A. to Plant Electrician M.: "We need to get the electricity costs down, take care of it." One year later. Managing Director F. to Operations Manager A.: "Electricity costs are still so high, how can that be?" Operations Manager A.: "I'll have to ask M. about that." Operations Manager A. to Plant Electrician M.: "We're still paying electricity costs like crazy. How is that possible, I told you to take care of it!" Plant Electrician M.: "Yes, boss, but the Controller cut the money for new drives, then the colleague was ill for four weeks and you know, day-to-day operations, it’s merciless, the phone rings all the time and everyone wants something from you!"

. .. this would not have happened with ISO 50001!
