In their own words
Arcadia Platform
Arcadia Platform is an energy intelligence platform for businesses managing utility costs, energy use, and sustainability programs. Plug centralizes utility bills, emissions data, and interval readings from electricity, water, and waste providers. Arcadia describes thousands of providers in more than 90 countries, with electricity readings at 15-, 30-, and 60-minute intervals and historical or ongoing collection. Its REST API connects to providers, retrieves usage data, and organizes it by site. Signal models portfolio electricity costs from tariff structures and usage data, with API calculations; Arcadia says its tariff database covers more than 30,000 tariffs. The platform includes solar and storage analysis, energy forecasting, and carbon tracking. Sustainability reporting integrates with Salesforce Net Zero Cloud, Watershed, Sweep, and other platforms. Arcadia positions it for finance, procurement, operations, energy management, and sustainability teams at large enterprises. It is offered through web and API access, with pricing available on request.
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.
