High-VoltagePowerEvacuationwith TransmissionSystems

At Onix Renewable Ltd, we specialize in the construction, maintenance, and upgrade of high-voltage overhead transmission lines up to 400kV — connecting remote mega solar and wind parks reliably to the national grid.

EHV Engineering Excellence

Building the Arteries of India's Clean Energy Grid

Mega solar parks and offshore/onshore wind corridors are often situated in remote arid deserts or coastal regions hundreds of kilometers away from industrial demand centers. Robust extra-high-voltage transmission lines are essential to evacuate this clean electricity without loss.

Onix manages the entire transmission lifecycle: engineering consulting, drone lidar profiling, foundation casting across marshy soils and rocky terrains, lattice tower assembly, and river/highway crossing spans.

Specialized tension stringing machines ensuring zero conductor scuffing

Turnkey interconnection with CTU (Power Grid) and State Transcos (GETCO, MSETCL)

Routine drone thermographic inspection and insulator string washing

Over 400 km of operational transmission lines standing without outage failure

Overhead Lines Construction Up to 400kV

Complete turnkey construction of extra high-voltage (EHV) transmission lines — including route survey, soil investigation, pile foundations, lattice tower erection, and tension stringing.

Optical Ground Wire (OPGW) Stringing

Simultaneous installation of dual-function OPGW cable providing lightning shielding for transmission towers and high-speed fiber-optic data channels for SCADA telemetry.

Specialized Live-Line Maintenance

Advanced live-line bare-hand and hot-sticking maintenance procedures carried out under full operating voltage, preventing expensive power shutdowns for industrial clients.

Statutory Right-of-Way (RoW) Management

Full-scope navigation of regulatory, environmental, and forest clearances, statutory crop compensation settlement, and PTCC approvals for smooth grid commissioning.
