Data in electricity trading
The first lecture of the IEEE BME SBC's Closed-Core Transformer Patent Memorial Semester was held by György Istvánffy, Director of HUPX Markets, who presented how data influences market decisions in both the short and long term on the electricity market.
In the introduction, he explained the main functions of the HUPX exchange: non-discriminatory, transparent, and anonymous trading; the role of the clearing service in ensuring security; and the IT-based data connections that make automated, real-time trading possible.
He introduced the main market segments: the day-ahead (DAM), intraday auction (IDA), and continuous intraday (IDC) markets. Among these, the IDC is becoming increasingly dominant — in August 2025 it exceeded 1.35 TWh of traded volume, illustrating the impact of the growth in renewable generation and real-time portfolio optimization.
A key topic of the lecture was the role of data and algorithmic trading. Through the HUPX Labs API, real-time order and trade data are made accessible, creating new opportunities for data-driven and automated trading strategies.
In the second part of the presentation, the presenter analyzed price volatility: due to the growing share of solar power generation, daily price fluctuations have increased significantly, especially in the summer months. The so-called “duck curve” phenomenon has intensified, meaning that prices remain low during the daytime and rise sharply in the evening hours.
Overall, the lecture provided a comprehensive overview of how data-driven thinking, along with the spread of renewable energy and energy storage, is transforming electricity market trading, and how HUPX is evolving into an increasingly digital and internationally interconnected platform.
