) has completed the 220 kV double circuit Kathalguri-Namsai transmission system five months before its scheduled deadline.
The line was energised late on Saturday night, a PGCIL statement said here on Monday.
The project, carried out under the Tariff-Based Competitive Bidding (TBCB) model, enhances the reliability of electricity supply across the region. Stretching 71 km, the new line connects the
Assam gas-based power plant operated by
NEEPCO
at Kathalguri to a modern 220 kV gas-insulated substation (GIS) at Namsai in Arunachal Pradesh.
A bay extension at the Kathalguri end has also been completed to improve system operations.
The infrastructure upgrade allows smoother power flow from the national grid into Arunachal Pradesh, while also improving voltage stability and providing critical system backup, essential for a dependable year-round electricity supply.
It is expected to significantly support the region's development initiatives, the statement said.
Arunachal Pradesh Deputy Chief Minister Chowna Mein praised the accomplishment.
"Kudos to PGCIL for their exemplary execution and unwavering commitment to the Northeast. This project is a cornerstone in our journey toward robust and reliable energy infrastructure," he said in a social media post.

PNGRB approves pivotal reforms in natural gas pipeline tariff regulations
New Delhi [India], July 4 (ANI): In a decisive move aimed at strengthening India's transition towards a cleaner, more efficient energy landscape, the Petroleum and Natural Gas Regulatory Board (PNGRB) has approved the Second Amendment to the Natural Gas Pipeline Tariff Regulations, 2025. In a release, the PNGRB stated that these sweeping reforms underscore PNGRB's commitment to developing a more transparent, consumer-oriented, and investment-friendly natural gas infrastructure in India. The reforms were approved during a recent Board meeting following extensive consultations with stakeholders across the industry. Anchored in the vision of 'One Nation, One Grid, One Tariff,' this regulatory overhaul reflects PNGRB's strategy to simplify the market structure, promote cleaner fuels, and build an inclusive gas-based economy. Among the key reforms, PNGRB has reduced the number of Unified Tariff Zones from three to two, simplifying the natural gas transportation system across the country. This initiative ensures a more equitable tariff structure and enhances access to natural gas, especially in underserved a consumer-centric move, the benefit of the Unified Zonal Tariff of Zone 1 has been extended nationwide to Compressed Natural Gas (CNG) and Piped Natural Gas (PNG) Domestic segments. This is poised to make natural gas more affordable for urban households and transport networks, thereby supporting broader clean energy stabilise tariffs and ensure efficiency in supply, PNGRB has mandated pipeline operators to procure at least 75 per cent of their annual system-use gas through long-term contracts (minimum three-year tenure). This will lower procurement risks, reduce transaction costs, and ultimately result in more predictable and affordable tariffs for consumers and investors alike. The PNGRB added in the release that it has introduced a dedicated Pipeline Development Reserve, utilising earnings from pipeline entities that exceed 75% utilisation benchmarks to fund future expansion. PNGRB has noted that 50 per cent of these net-of-tax earnings will be reinvested into infrastructure development, while the remaining 50 per cent will be passed on to consumers through tariff adjustments, creating a performance-linked, self-sustaining model for reforms represent a strategic blend of regulatory innovation and stakeholder-centric governance, ensuring that both consumers and industry players benefit equitably. By realigning tariff structures, incentivising long-term planning, and reinvesting in infrastructure, PNGRB is laying a strong foundation for India's cleaner, greener, and more inclusive energy future. PNGRB further added that it remains committed to enabling ease of doing business while keeping consumer affordability at the forefront, making natural gas the fuel of choice for India's evolving energy needs.
