Uses
The Renun hydroelectric power plant was built in Lae Rias Tor Nauli, one of 14 hamlets in Pegagan Julu IV Village, Sumbul District, Dairi Regency, North Sumatra Province, about 3.5 hours drive from Medan City. This project utilizes the water of the Renun River and eleven other rivers located in the Lae Pondom Protected Forest Area.

The 25-meter Lae Renun Bridge was built on the Renun River and became an important artery connecting Medan City to Sidikalang, Pakpak Bharat, and Nangroe Aceh Darussalam (NAD). The bridge that connects Sumbul and Sitinjo sub-districts in Dairi regency is very vulnerable during the rainy season, because the bridge is flooded with water up to 10 cm to 15 cm on the shoulder, so that passing vehicles do not have the choice but to pass the puddle on the bridge.
