| Deployment | Deployment options include on-premises Plant Optimizer, cloud applications connected through OpenBlue Bridge, and an on-premises no-internet option, with some possible weather-service connections. | The getting-started guide describes production deployment of Edge and Backend on Debian/Ubuntu or Docker. |
| Founded | 1885 | 2016 |
| Integrations | Plant Optimizer communicates with plant automation systems using BACnet, Modbus, LON, or OPC protocols. | The OpenEMS Ready list includes integrations across energy storage, batteries, solar and battery inverters, EV charging stations, meters, tariffs, and data services. |
| Intended users | The product is presented for plant operators and engineers, as well as building owners and consulting engineers managing company, campus, or city utility plants. | The marketplace describes an ecosystem for hardware manufacturers, software developers, research institutes, universities, freelancers, and students. |
| Purpose | CUPO is a package of software applications that reduces energy use, carbon footprint, and operating cost in heating, cooling, and distributed electricity generation plants while maintaining reliability. | OpenEMS is a modular open-source platform for monitoring, controlling, and integrating energy storage, renewable energy sources, and complementary devices and services. |
| Security | CUPO describes HTTPS encrypted communications, security certificates, and an audit log recording who changed what and when, with an explanation required for changes. | The documented Backend-to-Backend API supports BasicAuth when a connection is opened. |
| Support | Plant Optimizer support is available by support request form, email at [email protected], or phone at +1-414-524-2397. | The project invites users to get in touch through the OpenEMS Community forum and says it is glad to support third parties taking their first steps. |

OpenEMS
OpenEMS is a free, modular open-source platform for monitoring, controlling, and integrating energy storage, renewable sources, and related devices and services. Its stack combines OpenEMS Edge for on-site device communication and control, OpenEMS UI for browser and smartphone access, and OpenEMS Backend for connecting Edge systems over the internet for aggregation, monitoring, and control. The architecture supports fast PLC-like control and reusable device-independent algorithms. Integrations cover batteries, solar and battery inverters, EV chargers, meters, tariffs, and data services, using interfaces such as MQTT, Modbus/TCP, Modbus/RTU, InfluxDB, M-Bus, 1-Wire, JSON/REST, and JSON/Websocket. Edge and Backend use Eclipse Public License 2.0; UI uses GNU Affero General Public License 3. Production deployment guidance covers Debian, Ubuntu, or Docker, and Java 21 is required. Source is available online and on GitHub, with monthly releases described. The getting-started setup is intended for testing, not production.
