Sri Lanka: Kerawalapitiya - Port L Second Transmission Line Project

approved

The project involves constructing of approximately 16 kilometers (km) of 220kV single circuit underground transmission cable system from Kerawalapitiya Switching Station to Colombo Port L Grid Substation. Sri Lanka, through Ceylon Electricity Board (CEB), is undertaking the project to increase the transmission capacity of the electricity network to meet the growing electricity demand in the Greater Colombo urban development area including the upcoming Colombo Port City. Project activities include designing, supplying, constructing, testing, and commissioning a single circuit 220kV insulated underground cable system from Kerawalapitiya Switching Station to Colombo Port L Grid Substation. This cable system will be the second underground cable connecting the two stations. The existing first underground cable along the same route was commissioned in 2019, and it will not be sufficient to ensure reliability in the electricity transmission considering the projected additional demand in Colombo. Also, considering the renewable energy potential of the country's northern part, enhancing transmission capacity from Kerawalapitiya Switching Substation to Colombo Port L Grid Substation is essential to ensure overall grid stability and uninterrupted power transmission from renewable energy resources.
