The 32.5 MW HPP Boštanj is the second in the chain of six hydroelectric power plants on the lower Sava River. It is a hydroelectric power plant of the run-of-the-river and reservoir type, with three bulb-type generating units with a combined rated discharge of 500 m3/s, five spillways and an average annual production output of 109 GWh.

HPP Boštanj makes up nearly one percent of Slovenia’s present annual electricity production, provides also peak-load power in accordance with the needs and opens possibilities of implementing ancillary services. This power plant is remotely operated from GEN Control Centre and in normal hydrological circumstances operates unmanned, without on-site personnel.
