OpenEMS

About

Founded in 2018, OpenEMS is a ngo headquartered in Deggendorf, Germany with approximately 10-50 employees specializing in Solar, Wind, Energy Storage.

OpenEMS (Open Energy Management System) is the leading open-source operating system for the energy transition. Developed by the OpenEMS Association e.V., founded in 2018, it provides a vendor-independent, interoperable platform for managing distributed energy resources including solar inverters, battery storage systems, electric vehicle chargers, heat pumps, and grid infrastructure. The system uses advanced optimization techniques including genetic algorithms and Mixed-Integer Linear Programming to balance energy supply and demand, minimize CO2 emissions, reduce costs, and support grid stability. OpenEMS operates as an ecosystem with over 52 countries represented in its global community, supported by approximately 70 organizational members spanning manufacturers, service providers, research institutions, and universities. The platform is comparable to Android for smartphones, featuring both open and proprietary applications built on top of it. Key features include AI-based forecasting, real-time control, modular architecture, and the ability to optimize operating modes rather than raw power output. Two projects utilizing OpenEMS received The smarter E AWARD 2025 recognition.
