Viviana Power Tech Limited has commissioned a 400 kV double-circuit LILO transmission line to connect a 323.4 MW wind park to the power grid. The milestone reinforces the company's high-voltage engineering expertise and supports India's renewable energy evacuation infrastructure under national grid modernization initiatives.
The successful commissioning strengthens India’s renewable energy evacuation infrastructure, connecting major wind power generation to the national grid.
VADODARA — Power transmission and infrastructure engineering company Viviana Power Tech Limited announced on Tuesday, July 21, 2026, that it has successfully commissioned a 400 kV double-circuit Loop-In Loop-Out (LILO) transmission line. The high-voltage transmission infrastructure was erected to evacuate clean energy generated from a 323.4 megawatt (MW) wind park project.
The completion of the 400 kV LILO line represents a key technical milestone for Vadodara-headquartered Viviana Power Tech as it expands its execution footprint in high-voltage engineering, procurement, and construction (EPC) projects across India’s power sector.
High-Voltage Engineering and Grid Integration
The newly commissioned 400 kV double-circuit transmission line connects the 323.4 MW wind power generation facility directly to the state and national power grids. Loop-In Loop-Out (LILO) transmission structures allow power generated at renewable energy complexes to be seamlessly integrated into existing high-voltage transmission lines without interrupting continuous power flow across the national grid.
According to regulatory disclosures made by Viviana Power Tech to Indian stock exchanges, the scope of work included the complete engineering, procurement, tower erection, conductor stringing, testing, and final synchronization of the 400 kV line. High-voltage double-circuit transmission configurations provide operational redundancy, ensuring that power evacuation can continue even during routine maintenance or line segment outages.
Key technical specifications and project parameters include:
Voltage Capacity: 400 kV high-voltage double-circuit line.
Infrastructure Configuration: Loop-In Loop-Out (LILO) grid connection system.
Connected Generation Capacity: 323.4 MW wind energy park.
Primary Objective: High-efficiency power evacuation and grid stability for renewable power.
Strategic Pivot to High-Voltage Power Infrastructure
The successful commissioning of the 400 kV LILO transmission line highlights Viviana Power Tech’s technical transition from medium-voltage distribution works toward extra-high-voltage (EHV) transmission projects.
India’s rapid expansion of utility-scale solar and wind projects requires substantial transmission infrastructure upgrades under the national Green Energy Corridor initiative. Power developers require dedicated high-capacity transmission lines to move electricity from remote, wind-rich regions to industrial and urban demand centers.
In addition to its expanding EPC portfolio, Viviana Power Tech previously announced plans to invest ₹100 crore in a greenfield manufacturing plant near Vadodara, Gujarat, aimed at producing power equipment including transformers rated up to 400 kV by FY28. The dual capability of manufacturing high-voltage equipment while executing complex transmission line EPC projects positions the firm to capture a larger share of India's power grid modernization spend.
Market Impact and Industry Outlook
For utility companies, renewable energy developers, and industrial consumers, the commissioning of high-voltage transmission lines reduces grid congestion and curtails power curtailment risks for wind farm operators.
Industry analysts note that timely transmission commissioning is vital for maintaining project economics for renewable energy developers. Delays in transmission line readiness can result in stranded generation capacity. Viviana Power Tech’s execution of the 400 kV LILO line demonstrates operational capability in meeting strict synchronization schedules set by state and central transmission utilities.
For public market investors, the successful project delivery reinforces revenue visibility and execution metrics for Viviana Power Tech Limited, which migrated to the mainboard of the National Stock Exchange (NSE) in mid-2026.

FAQ Section
What is a 400 kV double-circuit LILO transmission line?
A Loop-In Loop-Out (LILO) 400 kV transmission line intercepts an existing high-voltage power line to connect a new generating station—such as a wind park—into the power grid using two parallel circuits for increased capacity and reliability.
Why is a 400 kV line required for a 323.4 MW wind park?
High-voltage transmission (400 kV) reduces electrical energy losses over long distances, allowing large volumes of electricity generated by a 323.4 MW wind park to be transmitted efficiently to power grids.
Where is Viviana Power Tech Limited headquartered?
Viviana Power Tech Limited is headquartered in Vadodara, Gujarat, and provides power transmission, distribution, and EPC services across India.
How does this project support India's renewable energy targets?
By building high-voltage transmission infrastructure, the project ensures that renewable power generated from wind assets can be fully evacuated into the national power grid without transmission bottlenecks.
