Construction of a new 220kV double-circuit electricity transmission line connecting Mannar and Mullikulam has commenced as part of Sri Lanka’s efforts to expand renewable energy generation.
The project, costing approximately Rs. 2.5 billion, was officially launched on Sunday (8) under the patronage of Energy Minister Anura Karunatilake.
The 26-kilometre transmission line will connect the Mannar 220/33kV grid substation to the proposed Mullikulam 220kV metering substation, enabling electricity generated by the planned 100MW Mullikulam wind power plant to be connected to the national grid.
The project will include the construction of 76 transmission towers and is expected to be completed within 540 days.
According to the Ministry of Energy, the project is being implemented by the National Transmission Network Service Provider (NTNSP), a fully state-owned company, with funding of approximately Rs. 2.5 billion from the Sri Lankan government.
The project is expected to strengthen electricity grid stability in the Northern Province, reduce power interruptions and voltage fluctuations, and improve the reliability of electricity supply.
It also supports Sri Lanka’s national target of generating 70% of its electricity from renewable energy sources by 2030, while reducing dependence on imported fossil fuels, including coal and diesel.
Environmental and social impact assessments began in 2022, while initial environmental approval was granted by the Central Environmental Authority in 2025. Cabinet approval for the project was obtained in February 2025.
The Ministry said the new transmission infrastructure would play a significant role in expanding wind power generation and strengthening Sri Lanka’s renewable energy network. (Newswire)
