A wind farm or wind park, also called a wind power station or wind power plant, is a group of wind turbines in the same location used to produce electricity. Wind farms vary in size from a small number of turbines to several hundred wind turbines covering an extensive area. Wind farms can be either onshore or offshore.
The Ceylon Electricity Board - CEB, was the largest electricity company in Sri Lanka. With a market share of nearly 100%, it controlled all major functions of electricity generation, transmission, distribution and retailing in Sri Lanka. It was one of the only two on-grid electricity companies in the country; the other being Lanka Electricity Company (LECO). The company earned approximately Rs 204.7 billion in 2014, with a total of nearly 5.42 million consumer accounts.

The electricity sector in Sri Lanka has a national grid which is primarily powered by hydroelectric power and thermal power, 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 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 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.
