Automated portfolio management software

Machine learning-based portfolio management is key to building a sustainable future, which is why the CET Group and its partners are constantly looking for new development opportunities.

With the proliferation of solar power plants, regulating the electricity system has become more complex and costly. These costs are primarily passed on to producers and traders.

CET Hungary offers innovative solutions at the system level and locally to minimize balancing energy costs. Primarily in the interest of free market and METAR producers, where the trader has added value.

Our NNSS application provides artificial intelligence-based forecasting for renewable producers, and its automated Hupx intraday trader module is able to continuously manage portfolio imbalances in line with XBID market liquidity. To increase liquidity, we use innovative storage solutions that are integrated with the NNSS system.
We offer a unique balancing energy reduction investment for PV production in the KÁT balance group based on the ESCO model.


With the help of the program, it is possible to integrate all portfolio elements, thus jointly managing retail and wholesale as well as production and storage capacities.
