Energy Management System

An energy management system monitors, analyses and controls energy flows within a company. It forms the central control layer for electricity consumption, on-site generation, storage operation and flexible loads.

Tasks of an energy management system

An energy management system captures energy data, evaluates load profiles and controls assets so that energy is used economically and efficiently. In practice, this is not only about monitoring, but about the active optimisation of energy flows.

• Transparency over electricity consumption and load curves
• Control of generation, consumption and storage
• Optimisation of costs, peak loads and self-consumption
• Automation of energy-related processes

Role in battery storage systems and PV systems

An energy management system is particularly important in combination with electricity storage, PV systems with storage or solar systems with storage. For example, it decides when a storage system is charged or discharged and how generated solar power should be used within the company.

Typical use cases in companies

An energy management system is the technical basis for many economically relevant applications:

• Self-consumption optimisation
• Peak shaving
• Use of dynamic electricity tariffs
• Control of charging infrastructure and flexible loads
• Optimisation of multi-use applications with battery storage

Technical and organisational significance

In a corporate context, an energy management system can be understood both technically and organisationally. Technically, it refers to the software and control layer for energy flows. Organisationally, it often also stands for systematic energy management, for example in the context of energy efficiency and management standards.

For commercial and industrial users, the technical function is particularly relevant: an energy management system makes energy flows measurable, automatable and economically optimisable.

Frequently Asked Questions (FAQs)

What is an energy management system?

An energy management system is a system for monitoring, analysing and controlling energy flows within companies. It helps to economically optimise electricity consumption, on-site generation, storage and flexible loads.

What is an energy management system used for?

An energy management system is used to reduce energy costs, lower peak loads, increase self-consumption and transparently control energy flows within companies.

What role does an energy management system play in battery storage systems?

An energy management system controls the charging and discharging of battery storage systems and decides when energy is stored, used or fed into the grid.

How does an energy management system support self-consumption optimisation?

An energy management system coordinates electricity generation, consumption and storage operation so that as much self-generated electricity as possible is used directly within the company.

Can an energy management system use dynamic electricity tariffs?

Yes. An energy management system can analyse electricity prices and control consumers or storage systems so that energy is preferentially drawn or stored during low-price periods.

Why is an energy management system important for companies?

Companies gain greater transparency over their energy flows, can specifically reduce electricity costs and make their energy supply more efficient, flexible and sustainable.
