Ceylon Electricity Board (Lakvijaya Power Plant) Lakvijaya Power Plant,Narakkalliya,Norochcholai

To fulfill the increasing demand on electricity, the Sri Lankan government launched a large-scale coal power project in Puttalam called “Puttalam Coal Power project”. The Puttalam Coal Power project having 900MW capacity (three similar units, each one having capacity of 300MW) was started in May 2006 and it is the first and largest Coal Power plant in Sri Lanka named as “Lakvijaya Power Plant”,(LVPP). Currently all the three units are connected to the national grid beard around 45% from total power generation. . Lakvijaya Power Plant currently employees more than 1000 employees and it is running under the generation division of Ceylon Electricity Board. The Power Plant is located on the coast, 100 meters inland from the shoreline, near the villages of Paniyadi and Narakkalliya in the Kalpitiya Peninsula approximately 12km west of city of Puttalam. The Power Plant is situated within the existing barren land located between the seashore and the agricultural land. 

The Power is generated by three identical generators, each having 300 MW capacities and coupled to three separate turbines which are operated by condensing steam. The high-pressure steam requirement of the three turbines is produced by three separate boilers using coal as fuel. Thus, the energy formed in burning coal is converted to electrical energy. 

Lakvijaya Power Plant Project was completed in two phases. Phase 01 included Unit 01, a 300MW coal fired power plant, auxiliary systems, coal handling system and the 220kV 117km double circuit transmission line to Veyangoda. Phase 02 included the Unit 02, Unit 03, extension of auxiliary systems and 220kV double circuit transmission line to Anuradhapura. Unit 01 of 300 MW contribution to the national grid along with the auxiliary systems was put into operation on 13th of February 2011. Unit 02 and unit 03 were commissioned and put into operation on 2014 adding a total of 900MW to the national grid.
