Cross-border transmission project to strengthen Sri Lanka’s renewable energy grid integration
Jyoti Structures Limited has entered into a joint venture with Hayleys Fentons Limited for the construction of the Mannar–Mullikulam 220kV Double Circuit Transmission Line in Sri Lanka, marking a major step in regional clean energy infrastructure development.
The project has been awarded by National Transmission Network Service Provider (Private) Limited under the Mullikulam Wind Power Transmission Project.
The transmission line will play a critical role in evacuating electricity generated from the Mullikulam Wind Power Projects and integrating it into Sri Lanka’s national grid.
The development strengthens Jyoti Structures’ international transmission portfolio and reflects the increasing focus on building resilient power infrastructure capable of supporting renewable energy expansion across South Asia.
According to the companies, the Mannar–Mullikulam 220kV Double Circuit Transmission Line is expected to enhance grid reliability while supporting Sri Lanka’s long-term clean energy transition goals.
The project also underlines growing collaboration between Indian and Sri Lankan infrastructure firms in the renewable energy and transmission sectors.
Amit Dutta, Chief Operating Officer of Jyoti Structures Limited, said the partnership with Hayleys Fentons demonstrates the company’s commitment to delivering advanced high-voltage transmission infrastructure in international markets.
He added that the project is expected to support Sri Lanka’s renewable energy ambitions and establish new benchmarks for transmission excellence in the region.
Hasith Prematillake, Managing Director of Hayleys Fentons Limited, described the transmission line as a vital link that will enable wind energy generated in Northern Sri Lanka to flow efficiently into the national grid. He noted that the company is simultaneously advancing its own 50MW wind project in Mannar, further contributing to the country’s clean energy transformation.
Roshane Perera, Executive Director and Chief Executive Officer of Hayleys Solar, said the project marks Hayleys Fentons’ expansion into large-scale infrastructure development.
He stated that the initiative would help the company’s engineering teams gain expertise in transmission and distribution systems, positioning the firm for future infrastructure opportunities in the region.
Industry experts believe projects such as the Mannar–Mullikulam transmission corridor are becoming increasingly important as South Asian nations accelerate investments in renewable energy generation. While solar and wind installations continue to rise, transmission infrastructure remains critical for ensuring stable and efficient power evacuation to national grids.
The latest collaboration also signals stronger momentum in regional energy connectivity and highlights the growing role of cross-border partnerships in supporting sustainable infrastructure development across emerging economies.
