Energy Management in Companies
What is energy management?
Energy management encompasses all measures that companies use to systematically track, analyze, and optimize their energy consumption. The primary goal is to use energy more efficiently, lower costs, and reduce environmental impact at the same time. To this end, all relevant energy parameters are precisely measured and monitored. Based on this data, processes are implemented in accordance with international standards such as ISO 50001.
Successful energy management combines measurement data, transparency, and continuous improvement. Companies that implement this process professionally significantly reduce their energy costs, improve their carbon footprint, and can take advantage of funding opportunities.
For which companies is energy management mandatory?
Starting in 2025, companies in Germany with a total annual energy consumption of 7.5 GWh or more are required to implement an energy management system (EnMS) in accordance with ISO 500001 or an environmental management system (EMS) in accordance with EMAS (Eco-Management and Audit Scheme).
While there is no general requirement for energy management for SMEs, they too can benefit from an EnMS in light of rising energy costs and general sustainability requirements. ISO 50005 provides a helpful foundation, offering clear guidance for the step-by-step implementation of an energy management system in SMEs.
Energy Management According to ISO 50001
ISO 50001 is an international standard that provides companies with a framework for implementing an energy management system. It calls for a continuous improvement process and specifies how energy performance indicators should be recorded and evaluated.
With Janitza’s software and hardware solutions, companies can meet the technical requirements for energy management that complies with ISO 50001.
What are the key elements of effective energy management?
Structured energy management consists of several interrelated steps. It can only realize its full potential if all of its components are taken into account.
1. Energy Monitoring and Measurement Technology
Comprehensive monitoring of energy flows at all relevant measurement points forms the foundation—from the central feed-in to individual consumers. Modern meters, such as those from Janitza, accurately measure current, voltage, power, and relevant power quality (PQ) parameters such as harmonics. Using this basic data, companies can analyze load profiles, calculate efficiency metrics and energy performance indicators (EnPIs), and identify risks such as voltage sags at an early stage.
2. Data Analysis and Software
The collected data must be analyzed and presented in an understandable way. This is where the GridVis® energy management software comes into play: It visualizes energy flows, creates customized dashboards, and enables analysis in accordance with ISO 50001/50006. This allows companies to maintain legally required records and transparently present key metrics such as CO2 emissions, energy consumption per cost center, or equipment utilization.
3. Identification of potential savings
Using measurement and analysis data, companies can pinpoint inefficient processes and develop appropriate solutions. This allows them to avoid peak loads, optimize cooling and compressed air systems, implement smart control systems, and integrate renewable energy sources.
4. Continuous Improvement
Energy management is not a one-time project, but an ongoing process. It is important to firmly embed it within the company, with clearly defined responsibilities, regular audits, and continuous optimization. Modern energy management systems, such as those offered by Janitza, support companies in their ongoing evaluation and thus make their successes clearly visible.
How Companies Benefit from Energy Management
Well-designed energy management is much more than just a mandatory requirement: It is a strategic tool that provides businesses with measurable benefits.
- Achieve cost savings: Efficient processes and the avoidance of peak loads significantly reduce your operating expenses.
- Increase supply security: Stable energy management protects against outages and ensures reliable production. Ensure competitiveness: In industry, energy management is a crucial factor in remaining efficient and resilient.
- Demonstrate sustainability: With transparent consumption data, you can improve your carbon footprint and meet ESG reporting requirements.
- Take advantage of incentives: Government programs, tax breaks, and lower grid fees shorten the payback period for your investments.
- Act strategically: With modern measurement technology and the GridVis® software, you gain full control over energy flows and lay the foundation for sustainable corporate management.
Frequently Asked Questions About Energy Management
You ask the questions, we have the answers—in our FAQ section, you’ll find the most common questions from Janitza customers regarding energy management.
What role does measurement technology play in energy management?
Metering technology is the foundation of effective energy management. Only with precise metering devices can consumption, grid quality, and load levels be reliably measured. Without this data, it is impossible to conduct sound analyses.
Which standards are relevant to energy management?
The most important standard for energy management in companies is ISO 50001. In addition, ISO 50006 (performance metrics) and DIN EN 50600 (for data centers) also play a role.
How quickly does an energy management system pay for itself?
The payback period depends on the industry and the measures implemented. Studies and real-world examples show that investments in energy monitoring systems often pay for themselves within 12 to 36 months through savings and efficiency gains.
