Lake Spullersee stores water from the surrounding mountains to generate energy in two hydroelectric power plants, the Braz power plant and the Spullersee power plant. This reservoir and the power plants are operated by the Austrian Federal Railways (ÖBB), so the electricity is used for the railways. According to the ÖBB, the frequency of the generated traction current is 16.7 Hz, while the grid frequency in Austria and Europe is 50 Hz. Lake Spullersee also serves as a flood protection facility.
