Svetly (Russian: Све́тлый, lit light, clear; Yakut: Сибиэтлэй, Sibietley) is an urban locality (an urban-type settlement) in Mirninsky District of the Sakha Republic, Russia, located 75 kilometers (47 mi) from Mirny, the administrative center of the district,[2] on the southern edge of the Vilyuy Plateau (a part of the Central Siberian Plateau), not far from the right bank of the Vilyuy River.

[citation needed] With the economic difficulties in the Soviet Union during the 1980s and in Russia during the 1990s, completion of the project was greatly delayed with the hydroelectric plant only beginning power generation between 2004 and 2008, with three of the four planned turbines in operation.

The power plant is managed by a daughter company of diamond mining corporation ALROSA.

Many of the settlement's inhabitants also commute for week-by-week shift work in remote diamond mines or in construction projects throughout the western region of the Sakha Republic, including the Eastern Siberia–Pacific Ocean oil pipeline.

The Evenk village of Syuldyukar lies 25 kilometers (16 mi) downstream along the Vilyuy and can be reached by boat in summer or via winter roads when the river is frozen.
