Station Service Road in Velachery set for a major revamp
The pockmarked Station Service Road in Velachery which has turned into a nightmare for motorists will soon undergo repairs, as the Chennai Corporation is all set set to take up improvement work on the stretch. The service road which was originally constructed by the Southern Railway and runs parallel to the Mass Rapid Transit System (MRTS) from Velachery to Taramani railway station is a boon for motorists to escape the heavily-congested Taramani Link Road to reach Rajiv Gandhi Salai at Taramani. The service road was paved to create access road to Perungudi and Taramani railway stations for the residents of East Velachery. Southern Railway handed over the 3.20-kilometre service road to the Chennai Corporation last year after it faced difficulties in maintaining the road. The civic body had, in the initial stages, installed the street lights for the road more than two years ago. The Station Service road had become unmotorable after it was dug up a few years ago for installing high tension underground power cable from the Taramani substation to Guindy substation for improving the electricity network by Tantransco. S. Harshvardhan, a resident of Madipakkam, said the road has become busy during morning and evening peak hours as hundreds of motorists bound to Rajiv Gandhi Salai use this stretch. However the condition of the road is bad with the concrete poured over the gravel to patch up the dug-up portion of the road having worn out. Half the two-lane road cannot be used. The road becomes slushy with water stagnating in puddles whenever there is even a drizzle as the storm water drain network constructed on both sides of the road has been damaged in several places. Social activist S. Kumararaja said the road was also once used by pedestrians who are now avoiding the uneven stretch riddled with potholes. The macro canal constructed to prevent flooding of residential colonies and help drain into the Pallikaranai marshland has been clogged with construction debris. A senior official of the Chennai Corporation said a Detailed Project Report (DPR) was in the final stages of preparation as the entire upgradation and improvement works are to be executed at a total cost of Rs. 26 crore excluding the road relaying work. For the road repavement component, which is to be executed by Bus Route Road division, the cost comes to Rs. 8.09 crores. While the tender has been opened the work order for identifying the contractor was yet to be finalised. The senior civic official pointing out the road improvement project to be carried out under 'MRTS Sammoga Cholai cum healthwalk' similar to pedestrian plaza would have the following components of well paved footpath, dedicated cycling track, road markings with walkway and kerb paintings, open gym, toilet block and waiting shelters, would completely transform the road. New street lights along with high mast lamps at all the junctions have been proposed. Both the macro and micro drains running along the road would be fully renovated, tge official added.

Tantransco flags issue of outage of NLC units, affecting load balance
Tamil Nadu Transmission Corporation Limited (Tantransco) has flagged the issue of outage of NLC generation units, resulting in shortage of the State's power allocation from Central generating stations (CGS). Tamil Nadu is losing a share of 745 MW out of the 1,999 MW due to forced outages in May, Tantransco Chairman J Radhakrishnan said in a recent letter addressed to NLC India Ltd Chairman and Managing Director. 'In the recent past years, NLC complex units are maintaining less generation citing various reasons due to which Tamil Nadu is getting less schedule against the allocated share there by facing much hardships in maintaining its 'Load-generation' balance, ', he said. Tamil Nadu State Load Despatch Centre is facing much hardship to maintain load-generation balance especially during non-solar peak hours, Mr. Radhakrishnan said. He called for necessary immediate measures in long term perspective to rectify the outage and maintain full generation from NLC Complex units during the current summer period especially during non-solar peak hours. Tantransco has also pointed out that there was a schedule shortfall of 219 MW from the available running units during the lighting peak hours on May 12, resulting in total affected share of 964 MW out of 1,999 MW. Tamil Nadu grid faces 5 peaks namely morning peak, solar peak, evening peak, lighting peak and Air-Conditioned (AC) night peak. Presently, the solar peak and evening peak is being met through renewable energy sources, namely solar and wind in addition to other generators, as per the State Energy Department's policy note for 2025-2026. Shortage of resources is faced during the morning peak, lighting peak and AC peak especially during the months of February, March, April and May. After meeting the demand with available sources viz., Thermal, Hydro, Central Generating Stations (CGS) share, Long Term Open Access (LTOA), Medium Term Open Access (MTOA) and Renewable Energy sources, the shortage in demand is met through short term tie ups such as Day Ahead Market (DAM), Day Ahead Contingency (DAC) Market, Long Duration contract (LDC) and Real Time Market (RTM), it added. Challenges faced in grid management are thermal outages, CGS share outages among others, the policy note pointed out. Tamil Nadu reached an all-time high peak power demand of 20,830 MW on May 2, 2024, and the record high daily consumption of 454.32 million units on April 30, 2024. Last month, Electricity Minister S.S. Sivasankar had said Tamil Nadu's power demand so far in the current summer has been lower than last year, due to rains in parts of the State. India's energy consumption stood at 148.7 billion units in May 2025, marking a 4% decline compared to the previous year. Unseasonal rains and the early onset of the monsoon kept temperatures lower than usual, leading to reduced electricity demand, as per Indian Energy Exchange.

TN grid curtailment wastes 70 million units of renewable energy amid falling demand, rising RPO targets
CHENNAI: Amid increasing push by centre and state governments to produce more renewable energy (RE), grid curtailment has led to 70 million units of renewable power not being evacuated by the Tamil Nadu Transmission Corporation (Tantransco) over the past one week, power producers said. State authorities said decrease in power demand due to change in weather led to the drop in evacuating renewable power. According to REPA (Renewable Energy Producers Association), the TN Load Dispatch Centre, which is the grid manager and Tantransco have been reducing power intake by curtailing the grid for three to five hours a day in substations, including Theni, Surandai, Veeranam and Aralvaimozhi, in the last one week to 10 days. This has resulted in eight to 10 million units of generated renewable energy going to waste every day, REPA said. The non-utilisation of RE has come amid an increase in Renewable Purchase Obligation (RPO) for Tamil Nadu set by the Union Ministry of Power. As per the RPO for Tamil Nadu in 2025-26, 33.01% of the state's power demand must be met through renewable sources. It is noteworthy that TN could not meet even last year's RPO target of 29.91% as renewable power generation fell short by 3%. REPA's chief advisor K Venkatachalam told TNIE that the wind season has begun early in Tamil Nadu this year and will continue until September. 'It is disappointing that the state-run power utility has started cutting off the grid and refusing to accept wind power from producers from the beginning of the season itself,' Venkatachalam alleged.

Erection of two new HT towers begins
Tamil Nadu Transmission Corporation Ltd (Tantransco) has begun work on a project to replace two high-tension power transmission towers that collapsed in Kollidam River last year. Tamil Nadu Power and Distribution Corporation (TNPDC) distributes power to Thiruvanaikoil and a few areas of Srirangam by transmitting power to Thiruvanaikoil substation through high tension lines from Thatchankurichi via Srirangam substation. However, it has been facing issues in power supply since the collapse of two HT transmission towers on the Kollidam riverbed due to heavy water flow near Alagiripuram in Thiruvanaikoil. Since then, power supply to Thiruvanaikoil is being managed by tapping power from other lines in Samayapuram and other places. But TNPDC faces a tough task in ensuring power supply to Thiruvanaikoil and its neighbouring areas. The people of Thiruvanaikoil encounter frequent disruptions in power supply and power fluctuations. The collapse of the HT tower was cited as the main reason for the disruptions in power supply. To solve the issue, Tantransco came out with a proposal to replace the two HT towers a few months ago. The Detailed Project Report (DPR) has been approved and the project has begun. A senior official of Tantransco told The Hindu that ₹3 crore had been sanctioned for installing two HT towers on the riverbed of the Kollidam near Alagiripuram. Considering the trouble in ensuring power supply to the affected people, it had been decided to implement the project on a war footing. Preliminary works had started and all materials needed for erecting the towers mobilised. A team of 30 specially skilled personnel would be engaged and the towers would be installed in a month. The official added that the locations of the new HT towers were identified based on a soil study by a civil engineering team of National Institute of Technology-Tiruchi. Its recommendations would be followed while undertaking pile foundation, tower erection and other works. The pile foundation was designed in a way to withstand heavy discharge of flow in Kollidam River. The power fluctuation and disruption in Thiruvanaikoil would be solved once the erection of towers.
