Construction of Mannar–Mullikulam 220kV power transmission line to begin today

Newswire reports that construction of a 26-kilometre, 220kV double-circuit transmission line between Mannar and Mullikulam has begun. The project launch took place on Sunday the 8th under the patronage of Energy Minister Anura Karunathilake, whose surname is rendered as Karunatilake in another Newswire report.

Newswire reports that the line will run from the Mannar 220/33kV grid substation to a proposed 220kV metering substation at Mullikulam. It is intended to carry electricity from the planned 100MW Mullikulam wind power plant in Mannar to the national grid.

Newswire reports that the project is estimated to cost Rs. 2.5 billion, funded entirely by the Sri Lankan government, and will involve 76 transmission towers. The work is expected to be completed within 540 days. Newswire identifies the National Transmission Network Service Provider, a fully state-owned company, as the implementing body.

Newswire reports that the transmission infrastructure is expected to improve grid stability in the Northern Province, reduce interruptions and voltage fluctuations, and make electricity supply more reliable. The outlet says the project also supports Sri Lanka’s goal of sourcing 70% of its electricity from renewables by 2030 and reducing reliance on imported coal and diesel.

Newswire reports that environmental and social impact assessments began in 2022, initial environmental approval came from the Central Environmental Authority in 2025, and Cabinet approval was obtained in February 2025.
