Tamil Nadu has installed 425.61 MW of domestic rooftop solar under PM Surya Ghar, though industry body NSEFI flagged TNERC network charges (~Rs 5,800/year for 5 kW) as a barrier. Meanwhile, the State is rolling out Vetri Kaivinai Kalaignargal Thittam (VKKT) offering Rs 10 lakh loans at 50% subsidy across 25 crafts, Brazilian firm WEG is investing Rs 2,000 crore in Dharmapuri, and TNUHDB, HR&CE, and NHAI reported key infrastructure milestones.
Key Facts
Rooftop Solar Policy: TN reached 425.61 MW under PM Surya Ghar (launched 13 Feb 2024); NSEFI sought removal of TNERC network fees levied since 22 Oct 2021 (~Rs 5,800/year for 5 kW).
VKKT Scheme: Vetri Kaivinai Kalaignargal Thittam supports 25 traditional craft trades with loans up to Rs 10 lakh and a 50% subsidy.
Dharmapuri FDI: Brazil's WEG is establishing a Rs 2,000 crore facility at SIPCOT Dharmapuri over 100 acres, generating 3,000 jobs.
Road Infrastructure: NHAI initiated a Rs 635 crore safety project on NH-44 and NH-785, alongside an MLFF toll plaza at Sriperumbudur.
GK Context
PM Surya Ghar: Muft Bijli Yojana aims to equip 1 crore households with rooftop solar systems providing up to 300 units of free electricity per month.
MLFF (Multi-Lane Free Flow): tolling eliminates physical toll booths using FASTag/GNSS-ANPR cameras for seamless highway travel.
Static GK
TNERC (Tamil Nadu Electricity: Regulatory Commission): Constituted under the Electricity Regulatory Commissions Act, 1998 (now governed by Electricity Act, 2003).
SIPCOT (State Industries Promotion: Corporation of Tamil Nadu): Established in 1971 to develop industrial parks across districts.
Mains Analytical Framework
Clean Energy Transition vs. Discom Viability: Balancing TNERC's grid maintenance cost recovery with household incentives for decentralised solar.
Balanced Regional Industrialisation: Attracting FDI like WEG to backward districts such as Dharmapuri promotes equitable job creation beyond Chennai–Hosur.
