The electricity sector in Sri Lanka has a national grid which is primarily powered by hydro power and thermal heat, with sources such as photovoltaics and wind power in early stages of deployment. Although potential sites are being identified, other power sources such as geothermal, nuclear, solar thermal and wave power are not used in the power generation process for the national grid.
The US state of Colorado has vast wind energy resources and the installed electricity capacity and generation from wind power in Colorado has been growing significantly in recent years. The growth has been sustained due to a combination of falling costs, continuing federal incentives, and the state's aggressive renewable portfolio standard that requires 30% of the state's electricity to come from renewable sources by 2020.
The Mampuri Wind Farms are a set of three wind farms located near the Lakvijaya Power Station, on the Kalpitiya peninsula, in Mampuri, Puttalam District, Sri Lanka. The wind farms, referred to as Mampuri-I, Mampuri-II, and Mampuri-III, was built successively, and consists of eighteen Suzlon wind turbines ranging from 1.25 MW to 2.10 MW. Mampuri-I was commissioned on 22 March 2010, and was the first wind farm in the country to reach the 10 MW installed capacity threshold. As the government only allows projects up to 10 MW, the three wind farms are registered under three different company names, namely Senok Wind Power, Senok Wind Energy, and Senok Wind Resource.

The 2019 Sri Lanka electricity crisis was a crisis which happened nearly a month from 18 March to 10 April 2019 faced by Sri Lanka caused by a severe drought that depleted water levels at hydroelectric plants. Sri Lanka experienced rolling blackouts for three to five hours per day except on Sundays in all parts of the island nation at different time schedules that started from 24 March 2019 to present. This is regarded as one of the worst blackouts confronted in Sri Lanka since 2016 and the longest ever blackout recorded in history of the country. However it was revealed that the main electricity providing institution Ceylon Electricity Board had restricted the power supply to almost all regions of the country without proper prior notice and implemented a time schedule unofficially from 24 March 2019. However the Ministry of Power and Renewable Energy revealed that it didn't grant and approve permission to CEB to impose power cuts.
