KSEB to revive Athirappilly hydel project
KOCHI: Struggling to meet the peak-hour power shortage in the state, the KSEB has decided to revive the 163MW Athirappilly Hydro Electric Project which was put on hold a decade ago following protest from environmental activists and tribal community.
According to an order issued by KSEB on April 24, the Centre for Environment Architecture and Human Settlements (C-Earth) had made a presentation on the development of tourism at Malankara dam, Idukki dam and Banasurasagar dam before top officials of the board on January 17, 2025. During the meeting, a proposal was made to modify Athirappilly power project as a tourism project and to prepare a master plan for development of amenities including tribal school, tribal hamlet and primary health centre.
The proposal was presented by the Director (Generation) before the Director Board on March 8, and the meeting of full-time directors passed a resolution on March 19 to accord sanction to remodel the Athdirappilly project. The KSEB has appointed a chief engineer to study the proposal made by C-Earth. A meeting held at the KSEB headquarters on April 28 discussed the issue.
KSEB Chairman Biju Prabhakar, in a statement, said the KSEB is conducting a viability study on implementing the Athirappilly hydel project as the first Integrated Tourism and Power Generation Project in the state.
'Water released after power generation will keep Athirappilly waterfalls alive'
'Based on the study, the KSEB will present the project before the Union and state governments. We are trying to explore the possibility of implementing the project by addressing the concerns raised. The aim of the study is to present the idea of implementing it through consensus with the support of all stakeholders,' he said.
According to Biju Prabhakar, the KSEB has been forced to reconsider the project as Kerala is depending on other states to meet around 70% of the its power demands. While the peak-hour demand of the state is 5,800MW, it has been able to generate only 1,800MW from its hydel projects. Though the board receives around 1,500MW power from solar power projects, it is available only during day time and does not help meet the peak-hour demand. With the demand rising, the board is forced to purchase power from realtime market at an exorbitant rate, he said.
'The project will not kill the Athirappilly waterfalls as the water released after generation will keep it alive,' he said.
As per the original proposal, the Athirappilly project will have a capacity to store 4 MCM water, which will be used to generate 163MW power. The project will have four generators with an installed capacity of 40MW. A 3MW generation unit will be installed above the Athirappilly waterfalls to keep it alive.
'The KSEB's projects at Sholayar and Poringalkuthu generate power only during peak hours during summer season. The water released from the projects after generation will be stored at the Athirappilly reservoir and used for power generation. The implementation of Athirappilly project will help ensure water flow at Athirappilly waterfalls through out the year,' said a senior official. 'If the project is implemented, we can implement various tourism projects at Athirappilly. The plantations in the surrounding areas can be used to provide amenities like parking, and recreational activities,' he explained.
The Ministry for Environment, Forest and Climate Change (MoEF&CC) had issued environment clearance for the project in 2001, 2005 and 2007. Now, the KSEB has to prepare a DPR and upload it on the Parivesh portal of the MoEF&CC. After getting approval from the ministry, the board will have to follow the procedure for environment clearance once again.

Goa IT dept designated to issue right of way NOCs
Panaji: The state cabinet on Wednesday designated the department of information technology, electronics, and communications (DITE&C) as the issuer of all permissions/NOCs under the Telecommunications Right of Way (RoW) Rules, 2024. The rules allow telecom service providers to put up infrastructure, such as cables and towers, on public or private property. State government directed all other line departments to conduct surveys, prepare reports, and submit them to DITE&C for processing the permissions/NOCs for telecommunication infrastructure on the RoW eServices Portal developed by the Centre, within the RoW Rules' deadline. The new Telecommunications Act, 2023, was enacted by Parliament and came into effect on June 26, 2024. Subsequently, Telecommunications Right of Way Rules, 2024, were enacted and came into force on January 1, 2025. The new rules replace the previous rules/policy and introduce new regulatory provisions. These rules aim to help in speeding up the expansion of telecommunication infrastructure, enhancing connectivity, and reducing procedural delays. The Indian Telegraph Act, 1885, was replaced by the Telecommunications Act, 2023, and the Indian Telegraph Right of Way Rules, 2016, were replaced by Telecommunications (Right of Way) Rules, 2024. The Goa Telecom Infrastructure Policy, 2020, becomes infructuous by virtue of the act. Considering the importance of implementing the directions in Goa, state government adopted the new Telecommunications Act, 2023, and the Telecommunications (Right of Way) Rules, 2024. The Goa Telecom Infrastructure Policy, 2020, stands withdrawn by the operation of law to give way to the new Telecommunications (Right of Way) Rules, 2024. All state government departments, urban and local bodies, and government corporations in the state must implement the Telecommunications Act, 2023, and the Telecommunications (Right of Way) Rules, 2024.

How Setting Your AC At 20 Degrees Celsius Could Cut Your Electricity Costs
The government will soon make it mandatory for air conditioners across India to operate only between 20 degrees Celsius (C) and 28 degrees C, Union Minister Manohar Lal Khattar announced on Tuesday. "Regarding air conditioning standards, a new provision is being implemented soon. The temperature standardisation for ACs will be set between 20 degrees Celsius to 28 degrees Celsius, meaning we won't be able to cool below 20 degrees Celsius or warm above 28 degrees Celsius," Mr Khattar said in a press conference. This was "to bring uniformity to air conditioning use and help reduce excessive power consumption due to extremely low cooling settings," the Minister of Housing & Urban Affairs told reporters. The announcement comes at a time when electricity demand is touching record highs, driven largely by extreme heatwaves and increased use of air conditioners. How Much Electricity Would This Save? Increasing the AC temperature by only 1 degree C can lead to a 6% reduction in electricity consumption, according to the Bureau of Energy Efficiency (BEE). So, if your AC was previously running at 18 degrees C and is now limited to a minimum of 20 degrees C, that is a 12% saving already. Most households tend to set ACs around 20-22 degrees C, and moving up to 24-26 degrees C can save up to 24%-30% in energy usage. Experts at BEE have also estimated that if India adopts 24 degrees C as the default setting across all ACs, it could save approximately 20 billion units of electricity annually, translating to savings of over Rs 10,000 crore in energy costs. Why This Matters In 2024, India's energy demand during peak summer days surged past 250 GW, an all-time high and a significant chunk of this was driven by residential cooling. According to the International Energy Agency (IEA), the country's cooling demand is projected to increase tenfold by 2050, making energy efficiency in this sector more urgent than ever. Setting a 20 degrees C lower limit helps reduce grid stress, encourages smarter AC use, and promotes energy-efficient appliances. Countries like Japan have already adopted similar practices, with recommended AC settings at 28 degrees C. Will Comfort Be Compromised? The BEE says that human comfort is generally maintained at 24 degrees C-26 degrees C when combined with the use of ceiling fans or proper insulation. Setting the AC at 18 degrees C is not only energy-intensive but also creates an uncomfortable chill, especially when moving between indoor and outdoor environments.

Indian govt report in 2022 foresaw China rare earth export crisis
As Indian manufacturers are scrambling to deal with supply-chain disruptions caused by China's restrictive policies on the export of rare earth metals, in many of which it has a near monopoly, experts are pointing to an early warning of this — in a 2012 strategy paper prepared by a steering committee headed by the then mines secretary Vishwapati Trivedi after a similar crisis caused after Beijing restricted supplies of the critical materials that are needed in the auto, space and clean energy industries. Also Read: 'China deal done': US to lower tariffs to 55%, allow Chinese students for higher ed Back then, they added, India felt the heat of Chinese squeeze and on August 9, 2011, the government set up an 11-member steering committee to develop a strategy paper on status and availability of rare earth elements (REE) and energy critical elements (ECE). The committee was chaired by the mines secretary and co-chaired by chairman of the Centre for Study of Science Technology (C-STEP). Members included senior officials and experts from the Department of Science & Technology (DST), the Geological Survey of India, the Bhabha Atomic Research Centre (BARC), the Department of Atomic Energy, the Defence Research & Development Organization (DRDO) and the chairman of India Rare Earth Ltd. Also Read: China can't afford double standards in fight against terror: S Jaishankar The forward of the committee's report titled ''Rare Earths and Energy Critical Elements: a Roadmap and Strategy for India', published in July 2012, said: 'In view of the increased demand of REE and near monopoly of supply from China, there is a need to develop national policies and implementation strategies for ensuring indigenous supply of REE… A Steering Committee was constituted by the ministry of mines with the ultimate intention of preparing a strategy paper for the government, providing short, medium and long term options along with proposals for specific policy & legislative interventions.' Also Read: 'Gratitude to Indian Navy': China on rescue of crew aboard cargo ship which caught fire off Kerala coast The report was blunt about Beijing's approach. 'China has been the major supplier of rare earths all over the world. Even though it has only 37% of global RE resources, it has captured the worldwide market to the extent of 97%. The low cost and efficient production process enabled China to monopolize the rare-earth market, forcing rare earth operations around the world to close down. Indian Rare Earths Ltd (IREL), which was once a leader in export of rare earth compounds had to shut down its operation in 2008,' the report added. 'Over the last couple of years China has imposed restrictions and curtailed its export by over 30% citing domestic demands as the reason. This unexpected decline has restarted rare earth operations once again throughout the world,' the report said. The same thing is happening again. Indian industries are suffering due to shortage of the critical minerals. According to a Reuters report published in Hindustan Times on Wednesday, automobile majors such as Maruti Suzuki have cut near-term production targets because of rare earth shortages. 'Government departments, particularly the ministry of commerce and industry, are holding hectic meetings with industry and other stakeholders to resolve the supply crisis. Government is using diplomatic channels asking Beijing to relax supply curbs for the Indian industries,' one of the people mentioned in the first instance said. The ministries of mines, commerce and external affairs did not respond to an email query on this matter. China's curbs on exports of rare earth materials have been officially raised through diplomatic channels by India, especially in view of the impact on manufacturers of electric vehicles, people familiar with the matter said. The issue reportedly figured in a meeting between Indian ambassador Pradeep Rawat and China's vice foreign minister Sun Weidong in Beijing on June 5. 'China's move was primarily aimed at the US and the impact on India was collateral damage. We are hopeful that the matter will be resolved soon,' one of the people said. It is not clear how China's deal with the US —the two countries reached a framework agreement that will now have to be approved by their respective Presidents —will affect this. The matter is expected to figure in discussions during a visit to India by Sun Weidong, a former Chinese ambassador to New Delhi, beginning on Thursday, the people said. Sun is visiting India to continue discussions with foreign secretary Vikram Misri aimed at normalising bilateral ties following the end of the military face-off in the Ladakh sector of the Line of Actual Control (LAC) last October. Auto manufacturers affected by the curbs on rare earth exports too have sought to reach out to Chinese authorities but without much success so far, the people said. Two days after India and China reached an understanding on withdrawing forces from the two remaining 'friction points' on the LAC last October, Prime Minister Narendra Modi and President Xi Jinping met in the Russian city of Kazan and agreed to revive several mechanisms to restore normalcy in ties and to address the long-standing border dispute.
