List of power stations in Sri Lanka

The installed electrical capacity and production of Sri Lanka by sources, from 2000 to 2014. Over 50% of the capacity was met via hydropower in 2000–2010.

Sri Lanka's electricity demand is currently met by nine thermal power stations, fifteen large hydroelectric power stations, and fifteen wind farms, with a smaller share from small hydro facilities and other renewables such as solar. Most hydroelectric and thermal/fossil fuel–based power stations in the country are owned and/or operated by the government via the state-run Ceylon Electricity Board (CEB), while the renewable energy sector consists mostly of privately run plants operating with a power purchase agreement with the CEB.^[1]

Per CEB's 2014 generation report, the country had a total combined installed generation capacity of 3,932 megawatts (MW), of which 2,115 MW (53.8%) was from thermal (900 MW/22.9% from coal and 1,215 MW/30.9% from fuel oil), 1,665 MW (42.3%) from hydroelectricity, and the remaining 152 MW (3.9%) from other renewable sources such as small hydro, wind, biomass, and solar. These generation sources produced a total of 12,357 GWh of electricity during that year, of which 7,508 GWh (60.8%), 4,534 GWh (36.7%), and 315 GWh (2.5%) was from thermal, hydro, and other renewables, respectively.^[1]

Non-renewable

As of 2015, 1,464 MW of the total thermal installed capacity was from state-owned fossil fuel power stations: 900 MW from Lakvijaya, 380 MW from the state-owned portion of Kelanitissa, 160 MW from Sapugaskanda, and 24 MW from Uthuru Janani. An additional 500 MW will be added to the total state-owned capacity after the late 2017 completion of the Sampur Power Station, which is being built with provisions to add a further 500 MW in the future. The remaining 641 MW of the installed thermal capacity are from six privately owned power stations. All thermal power stations run on fuel oil, except Lakvijaya and Sampur, which run on coal.^[2][3]

In an attempt to lower the current consumer tariff for electricity, the government has decided not to renew the power purchase agreements of privately owned thermal power stations when their licences expire, as it has done with the six now-decommissioned private power producers listed below.^[4] The government will utilize the new Sampur plant combined with new renewable sources to accommodate the lost private-sector capacity, with plans to introduce nuclear power after 2030.^[5]

The Ministry of Power and Renewable Energy also made a statement that no more coal-fired power stations will be commissioned after Sampur, making it and Lakvijaya the only two coal power stations in the country. Any future thermal power stations will also be natural gas–run, to reduce the nation's carbon footprint.^[6]

Hydroelectric

Hydroelectricity has played a very significant role in the national installed power capacity since it was introduced in the 1950s, with over 50% of the total grid capacity met by hydroelectricity in 2000–2010. Hydroelectricity was popularized as early as the 1920s by Devapura Jayasena Wimalasurendra, who is considered as the "Father of Hydropower" in Sri Lanka. It lost its majority share on the power grid when further thermal power stations were introduced in 2010. The hydropower resource in Sri Lanka is divided into three main regions based on water resource, namely the Mahaweli Complex, Laxapana Complex, and Samanala Complex.^[12][13]

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 penstocks). Further information on each power station is included in the corresponding water source article (i.e. dam). Privately owned "small-hydro" facilities (which are limited to a maximum nameplate capacity of 10 MW by state policy),^[14] are excluded from this list.

Solar power

Solar power is a relatively young segment in the energy industry of Sri Lanka. As of 2015, only two grid-connected solar farms were operational, one state-run and the other run by a private company, both of which had an installed capacity of less than 2 MW. Despite at least half a dozen private companies applying for development permits for photovoltaic and solar thermal projects,^[21] none have actually commenced construction.

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 National Renewable Energy Laboratory conducted further wind power studies in the island, before which the industry went into dormancy for a further seven years.^[23]

Unlike the other industries, Sri Lanka's wind energy industry witnessed a sudden boom in 2010, with the commissioning of the Mampuri Wind Farms, the first private-sector wind project in the country's history.^[24][25] It then suddenly crashed over the following four years after numerous scandals and hidden political dealings surfaced, involving key governing bodies such as the Sustainable Energy Authority and Ceylon Electricity Board, along with a number of senior individuals.^[26]

The last privately owned first-come, first-served style wind farm projects, the Pollupalai and Vallimunai Wind Farms, were completed in late 2014, by when the construction of new privately owned wind farms were suspended until further notice by presidential order.^[26] The largest private-sector beneficiaries of the "wind power boom" are Windforce and Senok, which currently own seven and three separate wind farms respectively, of the total of 14 privately owned wind farms in operation as at 2015.^[27] The other companies in the market include the semi-private LTL Holdings, Aitken Spence, and Willwind, which are currently operating four wind farms in total.^[21]
