Mannar-Mullikulam 220kV wind power transmission line: Rs 2.5 billion construction begins

Construction has begun on a new 220-kilovolt double-circuit electricity transmission line between Mannar and Mullikulam. The project is being implemented as part of efforts to expand renewable energy generation.

The project, costing about Rs 2.5 billion, was officially launched on Sunday (8th) under the leadership of Energy Minister Anura Karunathilaka.

The 26-kilometre line will connect the Mannar 220/33kV grid substation with the proposed Mullikulam 220kV metering station, linking electricity generated at the planned 100-megawatt Mullikulam wind power plant to the national grid.

The project, in which 76 transmission towers will be erected, is expected to be completed within 540 days.

It is being implemented by the fully state-owned national electricity transmission network service provider, with about Rs 2.5 billion in funding from the Sri Lankan government.

The project will strengthen grid stability in the Northern Province, reduce power outages and voltage fluctuations, and advance the national goal of sourcing 70 per cent of electricity from renewable energy by 2030, reducing dependence on imported fuels including coal and diesel.

Environmental and social impact assessments began in 2022; the Central Environmental Authority granted initial approval in 2025, and Cabinet approval was obtained in February 2025, the ministry said.
