Open Source Energy Management System

OpenEMS - the Open Source Energy Management System - is a modular platform for energy management applications. It was developed around the requirements of monitoring, controlling, and integrating energy storage together with renewable energy sources and complementary devices and services like electric vehicle charging stations, heat-pumps, electrolysers, time-of-use electricity tariffs and more.

If you plan to use OpenEMS for your own projects, please consider joining the OpenEMS Association e.V., a network of universities, hardware manufacturers, software companies as well as commercial and private owners, and get in touch in the OpenEMS Community forum.

OpenEMS IoT stack

The OpenEMS 'Internet of Things' stack contains three main components:

  • OpenEMS Edge runs on site, communicates with devices and services, collects data and executes control algorithms
  • OpenEMS UI is the real-time user interface for web browsers and smartphones
  • OpenEMS Backend runs on a (cloud) server, connects the decentralized Edge systems and provides aggregation, monitoring and control via internet

Features

The OpenEMS software architecture was designed to leverage some features that are required by a modern and flexible Energy Management System:

  • Fast, PLC-like control of devices
  • Easily extendable due to the use of modern programming languages and modular architecture
  • Reusable, device independent control algorithms due to clear device abstraction
  • Wide range of supported devices and protocols

System architecture

OpenEMS is generally used in combination with external hardware and software components (the exception is a simulated development environment - see Getting Started). As a brief overview, this is how OpenEMS is used in production setups: alt text

Open Source philosophy

The OpenEMS project ist driven by the OpenEMS Association e.V., a network of users, vendors and scientific institutions from all kinds of areas like hardware manufacturers, software companies, grid operators and more. They share the common target of developing a free and open-source platform for energy management, that supports the 100 % energy transition.

We are inviting third parties to use OpenEMS for their own projects and are glad to support them with their first steps. In any case if you are interested in OpenEMS we would be glad to hear from you in the OpenEMS Community forum.

OpenEMS development was started by FENECON GmbH, a German company specialized in manufacturing and project development of energy storage systems. It is the software stack behind FEMS - FENECON Energy Management System and widely used in private, commercial and industrial applications.

OpenEMS is funded by several federal and EU funding projects. If you are a developer and you would like to get hired by one of the partner companies or universities for working on OpenEMS, please send your motivation letter to info@openems.io.
