The city emerged upon the construction of the Bratskaya damn and hydroelectric plant. The city consists of a couple of spread out residential developments and villages, located at considerable distances from one another.

Trolleybuses operate within one residential development only – in the Tsentralniy Zhilrayon (the Central Residential Development), also known as Novobratsk (the New Bratsk). Upon the initial construction, the trolleybus system’s primary function was meant to transport workers to the Bratskiy Lumber Industrial Complex (BLPK) located 3 km. south of the residential development. As city’s economic priorities evolved, the system’s primary objective shifted toward serving the inner city.
