Subansiri Lower hydro project Unit-2 commissioned, boosting clean power
Union Power Minister Manohar Lal inaugurated the commercial operation of Unit-2 (250 MW) of the Subansiri Lower Hydroelectric Project via virtual mode. The 2,000 MW project sits on the Arunachal Pradesh–Assam border and strengthens India’s renewable energy capacity in the North-East. With Unit-2 now operational, three more 250 MW units are expected to be commissioned soon, while the remaining four units are scheduled for 2026–27. When fully commissioned, the project will generate about 7,422 million units annually, improving grid resilience and regional power supply. The Subansiri Lower Hydroelectric Project is a major pillar of India’s green energy push.

Gujarat leads with 5 lakh rooftop solar installations
Gujarat continues to lead India in rooftop solar installations, reaching 5 lakh residential systems. The state is on track to meet half of its target of 10 lakh rooftop installations by March 2027. Residential consumers have benefited significantly, receiving subsidies totaling about Rs 3,778 crore under the rooftop solar scheme. The growing installations reflect broad public support for clean energy and policy incentives that reduce the cost of solar adoption. The trend also signals stronger private investment and decentralised generation, contributing to energy security, reduced peak demand, and climate goals across the state.

Railways deploys AI-based wildlife protection system on tracks
Indian Railways has strengthened its AI-based system to safeguard wildlife along railway lines. New AI cameras alert locomotive pilots half a kilometre ahead to prevent collisions with elephants, lions, and tigers. An intrusion detection system using Distributed Acoustic Sensing (DAS) is deployed on rail corridors. The system is currently active on 141 route kilometres of the Northeast Frontier Railway and has delivered encouraging results. Based on performance, tenders have been issued for expansion across 981 route kilometres. The initiative aims to reduce wildlife fatalities and human-wildlife conflict while keeping rail operations safe and efficient.

Tamil Nadu Launches Smooth-Coated Otter Conservation Initiative
Tamil Nadu launched a focused conservation initiative to protect the smooth-coated otter in the Cauvery Delta. The species is the largest otter in Asia and a key indicator of wetland health. Otter groups, called bevvies, hunt cooperatively and help regulate fish populations. The programme aims to reduce human–wildlife conflict and protect freshwater habitats, with fieldwork in river canals, tributaries, and mangrove edges where otters shelter in holts along riverbanks.

NHAI unveils wildlife-safe road on NH-45 in Madhya Pradesh
The National Highways Authority of India (NHAI) debuted India’s first wildlife-safe road feature on NH-45 in Madhya Pradesh. The stretch includes table-top red road markings designed to reduce wildlife-vehicle collisions as the route passes through Nauradehi Wildlife Sanctuary and Veerangana Durgavati Tiger Reserve. The 11.96-kilometre section between Hiran and Sindoor lies about 60 kilometres from Jabalpur and traverses dense forest habitats. The initiative demonstrates a balance between road development and conservation, offering a potential model for wildlife-friendly infrastructure across India and encouraging drivers to slow down in ecologically sensitive zones.
