The hydropower resource in Sri Lanka is divided into two main regions based on water resource, namely the Mahaweli Complex and Laxapana Complex. While most hydroelectric power stations are named after their water source (i.e. the name of the dam and/or reservoir), a number of facilities have different names due to the fact that they are located larger distances apart (connected via underground

Wind power

Sri Lanka's wind power sector saw activity as early as 1988, when studies were conducted to build a pilot wind project in the Southern Province. More than a decade later, the state-owned 3 MW Hambantota Wind Farm was commissioned. The industry stayed dormant till 2003, when the
