Jyoti Structures Limited, India, as lead partner, along with Hayleys Fentons Limited, Sri Lanka’s No. 1 Solar EPC and MEP contractor, has signed a joint venture contract for the construction of the Mannar–Mullikulam 220kV Double Circuit Transmission Line. The contract is the inaugural award issued by the newly established National Transmission Network Service Provider (Private) Limited (NTNSP), under the Mullikulam Wind Power Transmission Project.
The project involves the development of critical transmission infrastructure required to evacuate power generated by the Mullikulam Wind Power Projects to the national grid. Once completed, the transmission line will play a key role in improving grid reliability, enabling renewable energy integration, and supporting Sri Lanka’s long-term energy sustainability goals.
Amit Dutta, Chief Operating Officer of Jyoti Structures Limited, stated: “Jyoti Structures is proud to partner with Hayleys Fentons on this landmark project. With our extensive expertise in high-voltage transmission infrastructure, we look forward to delivering a resilient transmission network that will support Sri Lanka’s renewable energy ambitions and set a strong benchmark for transmission excellence in the region.”
Hasith Prematillake, Managing Director of Hayleys Fentons Limited, said: “This signing is a declaration of confidence in Sri Lanka’s energy future. The Mannar–Mullikulam 220kV transmission line is the artery through which the wind energy potential of the North will flow into our national grid. As we advance our own 50MW wind project in Mannar in parallel, we are proud to be contributing to Sri Lanka’s clean energy transition on multiple fronts, and this milestone brings that vision meaningfully closer to reality.”
Roshane Perera, Executive Director and Chief Executive Officer of Hayleys Solar, stated: “This marks the beginning of a new era for Hayleys Fentons as we expand into the infrastructure sector. The project presents a significant opportunity for the company to unlock new growth potential while creating valuable exposure for our engineering team in power transmission and distribution projects. It will enable our engineers to build specialised expertise in this domain and position the company to successfully undertake similar large-scale infrastructure projects in the future.
The Mannar–Mullikulam 220kV Double Circuit Transmission Line Project marks another significant addition to the expanding energy infrastructure portfolio of Hayleys Fentons, reflecting the company’s continued commitment to supporting Sri Lanka’s sustainable development agenda through engineering excellence and future-focused infrastructure solutions.
