The development of new simulation techniques by using Artificial Intelligence (AI) has become an improved tool to better forecast energy prices. This paper demonstrates building and validating a short term model for Hungarian day ahead power market — HUPX electricity price forecasting. This models takes into account multiple sources of information; the data set used is a table of historical hourly loads, electricity prices and other regional information's. Paper is discussing the application of intelligent systems to short term electricity prices forecasting and outlining proposed research direction.
