A severe winter storm recently caused massive blackouts in the US state of Texas, leaving millions in freezing temperatures and darkness for days and claiming more than 30 lives. That led to some netizens in China wondering "If similar extreme weather hit China, would the same tragedy happen?" The answer is probably "no", as China's power supply system has several advantages. Texas has an almost completely isolated grid system – power from other states accounts for only 1.7 percent of its maximum capacity. As a whole, the United States doesn't have a national grid system and lacks coordination among states. In comparison, China has a national grid system, which is composed of six regional systems. Except the northwestern region, which has a 750-kilovolt backbone power network, the other five regions all have 500-kV networks, with networks in the North China and East China boasting 1000-kV ultra-high voltage power transmission lines. When Texas was hit by the blackout, … [Read more...] about Could China’s power grid withstand a Texas-sized disaster?

Even unique ‘islanding’ system, Rs 500-cr annual surcharge failed to protect city. What went wrong? A power grid comprises a network of transmission lines connecting a power plant to households through high-voltage lines. In between, the electricity is sent through a number of substations, where the high voltage aka transmission voltage is ‘stepped down’ to distribution voltage to allow it to be used in households without frying up appliances. In Mumbai, these substations are at Salsette, Kalwa, Borivali, Vikhroli, Kharghar and Versova. The city gets electricity from four distributors: the state-owned Maharashtra State Electricity Distribution Company Limited (MSEDCL), BEST Undertaking, and private players Tata Power and Adani Electricity . The blackout, although a surprise, wasn’t the result of an overnight, single failure. Problems began three days ago. ♦ October 10: One of the transmission grids—the 400 kV Talegaon-Kalwa line—was shut down to address a ‘technical … [Read more...] about Multiple power trips, grid separation failure to blame

By Avik Chattopadhyay The spark On February 1, 2021, after the budget presentation, on being asked by a television reporter why there was no mention of electric mobility , Nitin Gadkari, the Union Road Transport and Highways Minister, made an interesting remark. “The country needs to explore more self-sufficient and self-reliant methods of powering mobility to reduce our dependence on imports!” This was significant and one needs to read between the lines; especially if one couples the National Hydrogen Mission [NHM] that was announced by the Finance Minister. On February 8, the Ministry of New & Renewable Energy told the media that the draft of NHM will be ready in two months. Link this with the fact that Delhi inducted Hydrogen-CNG buses in its fleet in October 2020. Fast forward a few weeks, and on February 23, the Indian Auto LPG Coalition [the industry body of auto LPG stakeholders] impressed upon the government to promote a few alternative clean energy … [Read more...] about Opinion: ‘Atmanirbhar’ alternatives to electric mobility!
