Renewable forecasting, virtual power plant and grid integration software

IT Services and IT Consulting Oldenburg, Lower Saxony 201–500 employees Founded 2004 Public Company

emsys builds IT for integrating wind, solar and decentralized assets into power markets and grids, from forecasts to virtual power plant control. A Java/Spring and Python core with Kafka, RabbitMQ and Cassandra points to high-volume streaming of plant measurement data, and recurring job-post themes around data quality and measurement irregularities show where that pipeline strains. Hiring is engineering-heavy, Germany-only and currently slow.
