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 around one percent of Slovenia’s present annual electricity production, but will also provide peak-load power and open up possibilities for selling ancillary services. This power plant is going to be fully automated, unmanned and remotely operated from the control centre.
