General data on generation: circuit of reliable acquisition of electric power

The appropriately designed and planned use of the capacities of Dravske elektrarne Maribor during average annual flows allows an annual generation of 2664 million kWh of electric power. The largest quantity generated by the Drava power plants is 1245 million kWh in the summer period, 846 million kWh during transition periods and 564 million kWh during the winter. More than 40 % of generation is ensured by Zlatoličje HPP (21,5 %) and Formin HPP (20,8 %).

The importance of the Drava power plants is amplified by their ability to guarantee reserve power in case of breakdowns in the electric power system of Slovenia. By filling the reservoirs during the night and emptying them during the daytime, the Drava power plants can move a portion of their daily generation from periods of smaller demand to periods of higher demand at least eight months of the year. Operation utilising flow accumulation also allows for the participation of power plants in the secondary frequency and power regulation of up to 45 MW.

The capacity of the upper Drava power plants due to implemented sequential refurbishment of Dravograd HPP, Vuzenica HPP, Vuhred HPP, Ožbalt HPP, Fala HPP and Mariborski otok HPP concluded in 2005 was increased by 67,3 MW with generation higher by almost a tenth.

The total net capacity of the Drava power plants in Slovenia is 591,950 MW while the total generation of the plants represents around quarter of the electric power generated in Slovenia.
