| CONVENTIONAL HYDRO |
| Conventional hydro is a term that refers to hydro power generation schemes that have been around since the early periods of the power industry in Sri Lanka. These include the big dam power generation projects in Sri Lanka like Randenigala, Victoria, Rantambe, Ulhitigala, Kotmale...etc. The major hydro schemes that are being developed at present include the Upper Kotmale project, Broadlands, Uma Oya and Monaragala. |

| Hydroelectricity generation has played a major role in power generation in Sri Lanka, since the commissioning of the first hydroelectric power plant in 1950. The Sri Lanka power sector was dominated by hydro power until 1996, and almost 94% of the annual power demand in 1995 was met via hydro power generation. But, although there were several hydro power capacity additions, the share of hydro continued a reducing trend since mid-90’s due to the availability of new sites economically feasible for hydro power development. Currently, hydro power stations are operated to supply both peaking and base electricity generation requirements. |

| The major hydro schemes have been exhausted to the maximum potential. Refer the following chart, it is evident that there is no increase in the installed capacity of major hydro since the early 1990’s. Today, continuing increase in the level of electrification and industrial and commercial development is increasing the demand on electricity, whilst the exploitable major hydropower remaining static. |
