[Abstract] Forecasting energy production by hydropower plants (HPP) is a challenge because of their correlation with many exogenous variables such as precipitations, water inflow, temperature, the minimum and maximum level of the HPP, etc. Albania has a favorite geographical position which makes the electrical energy the main source of energy produced in the country. In our work, we try to analyze hourly and daily data of energy produced in the main cascade of the country which produces the main amount of energy consumption. Our focus is on analyzing the situation of energy demand on a 24 hour period and also on a weekly /monthly period. We analyze the seasonality patterns of the energy demand and try to fit different models to predict the upcoming season (hours or days). Several modeling strategies among hierarchical forecasting, neural network, multistage forecasting, econometric forecasting models were tested and the best was selected looking at the performance obtained on the testing period. Our goal is to use the proposed models to obtain the forecast for electric energy demand in the country which will help the Albanian Power Corporation (KESH) to build various scenarios on optimizing the country demand and production capacities on HPP cascade.
