2012 India blackouts

Widespread power outages in India February 2015 July 2022 thumb|Map of affected states: #9a0808 In Northern India #bc4242 In Eastern and North-Eastern India Two severe power outages affected most of northern and eastern India on 30 and 31 July 2012. The 30 July 2012 blackout affected over 400 million people and lasted about 13.5 hrs. During that period, it was the largest power outage in history by number of people affected, beating the January 2001 blackout in Northern India (230 million affected). Similar conditions caused a blackout on the next day, which remained the largest power outage in history 2025 May y. The outage on 30 July affected more than 620 million people (9% of the world population at the time and half of India's population), spread across 22 states in Northern, Eastern, and Northeast India. An estimated 32 gigawatts of generating capacity was taken offline. Of the affected population, 320 million initially had power, while the rest lacked direct access. Electric service was restored in the affected locations between 31 July and 1 August 2012. Background India is the world's third largest producer and consumer of electricity after the United States and China; but has long suffered from unreliable electrical infrastructure. The northern electrical grid had previously collapsed as recently as 2001. Around the time of the blackouts, an estimated 27% of energy generated was lost in transmission or stolen. About 25% of the population, about 300 million people, had no electricity at all. Peak supply fell short of demand by an average of 9%, and the nation suffered from frequent power outages that lasted as long as 10 hours. Efforts were underway (and continue) to reduce transmission and distribution losses, and increase production.Express News Service 26 July 2013 Address power transmission and distribution losses http://www.newindianexpress.com/states/odisha/Rs-3600-crore-power-sector-plan-to-cut-Transmission-and-Distribution-loss/2013/07/26/article1702694.ece dead https://web.archive.org/web/20130731140759/http://newindianexpress.com/states/odisha/Rs-3600-crore-power-sector-plan-to-cut-Transmission-and-Distribution-loss/2013/07/26/article1702694.ece 31 July 2013 The private sector had spent $29 billion to build their own independent power stations in order to provide reliable power to their factories, and the five biggest consumers of electricity in India had private off-grid supplies. In total, Indian companies had 35 GW of private off-grid generation capacity at the time of the blackouts and planned to add another 33 GW to their off-grid capacity in the aftermath.Rajesh Kumar Singh and Rakteem Katakey 3 August 2012 Ambani, Tata 'Islands' Shrug Off Grid Collapse: Corporate India https://www.bloomberg.com/news/2012-08-02/ambani-tata-islands-shrug-off-grid-collapse-corporate-india.html 6 August 2012 Bloomberg Administratively, the Indian electrical power system is divided into Northern, Western (which, despite the name, is south of the Northern region), Southern, Eastern, and Northeastern regions. The Southern region only connects through high-voltage direct current (HVDC) interties, but the other four systems operate in synchrony.5 All operate at a nominal 50 Hz.April 2024 The Northern region also operates an internal HVDC line to transport power from generators in the east to consumers in the west.5 On the days of the blackout, utilities had taken multiple parallel transmission lines out of service for scheduled maintenance, leaving few transmission circuits connecting the Western and Northern grid regions.iv-v The monsoon stressed the few remaining lines.An analysis of large-scale transmission power blackouts from 2005 to 2016 Maxime Velay Meritxell Vinyals Yvon Besanger Nicolas Retière 53rd International Universities Power Engineering Conference Sep 2018 Glasgow 8541901 10.1109/UPEC.2018.8541901 hal-02330748 https://hal.archives-ouvertes.fr/hal-02330748/file/article_MaximeVelay_IEEE.pdf However, there was also unusually large electrical demand, and the Northern Region imported 4-6 GW of power from its neighbors.iv-v,8,21 Sequence of events 30 July In addition to the transmission lines under maintenance, multiple interties between the Western and Northern regions tripped out of service on the evening preceding the blackout, leaving only the 400 kV Bina-Gwalior line connecting the Western and Northern regions. The line was sized to transfer about 700 MW power with optimum efficiency, but could carry substantially more without damage, and at the time of the blackout carried about 1450 MW. The Northern and Western Regions' Load Despatch Centres (LDCs) requested that the Northern region shed load and the Western region reduce generation to unload the power line, but neither utility did so adequately.9–10 At 02:35 a.m. IST (21:05 UTC on 29 July), the high load on the Bina-Gwalior line tripped the line's circuit breakers.11 Power flowing from the Western region to the Northern region now had to circle through the Eastern region, and transmission losses from the new routing left the Northern region undersupplied. Consequently, it began to lose frequency, and circuit breakers on the Northern-Eastern transmission lines acted to separate the now-out-of-sync grids. Although the Northern region had incorporated underfrequency load shedding devices adequate to compensate for the missing imported power, the scheme failed to perform as designed and the Northern grid collapsed.11–12 All major power stations were shut down in the affected states, causing an estimated shortage of 32 GW. Officials described the failure as "the worst in a decade",http://india.blogs.nytimes.com/2012/07/30/power-restored-to-most-of-north-india/ Power Restored to Most of north India Sruthi Gottipatti and Niharika Mandhana 30 July 2012 The New York Times 30 July 2012 and a power company director noted that the "fairly large breakdown...exposed major technical faults in India's grid system. Something went terribly wrong which caused the backup safety systems to fail." More than 300 million people, about 25% of India's population, were without power. The Associated Chambers of Commerce and Industry of India (ASSOCHAM) stated that the blackout had "severely impacted" businesses, leaving many unable to operate.31 July 2012 When the lights went out http://www.hindustantimes.com/India-news/NewDelhi/Power-failure-in-7-states-no-Metro-Trains-in-Delhi-today/Article1-904035.aspx dead https://web.archive.org/web/20120730105408/http://www.hindustantimes.com/India-news/NewDelhi/Power-failure-in-7-states-no-Metro-Trains-in-Delhi-today/Article1-904035.aspx 30 July 2012 31 July 2012 Hindustan Times Railways and some airports were shut down until 08:00,https://www.bbc.co.uk/news/world-asia-india-19043972 Power cut causes major disruption in northern India 30 July 2012 BBC News 30 July 2012 although the busiest airport in South Asia, Delhi Airport, continued functioning on backup power. The outage caused "chaos" for Monday morning rush hour, as passenger trains were shut down and traffic signals were non-operational. Trains stalled for three to five hours. Several hospitals reported interruptions in health services, while others relied on back-up generators. Water treatment plants were shut down for several hours, and hundreds of thousands of people were unable to draw water from wells powered by electric pumps.http://www.hindustantimes.com/India-news/NewDelhi/Power-grid-failure-FAQs/Article1-905428.aspx Power grid failure: FAQs 31 July 2012 Hindustan Times 31 July 2012 dead https://web.archive.org/web/20120730213932/http://www.hindustantimes.com/India-news/NewDelhi/Power-grid-failure-FAQs/Article1-905428.aspx 30 July 2012 Oil refineries in Panipat, Mathura and Bathinda continued operating because they have their own captive power stations within the refineries and do not depend on the grid. It took 15 hours to restore 80% of service, which Power Grid Corporation of India chairman's called "a record time". 31 July The following day recapitulated much of the July 30 collapse. Again, few grid lines connected the Western and Northern regions; again, those interties loaded beyond usual service; again, the LDCs requested the Northern region shed load and the Western region reduce generation; again, the utilities' reaction was too small; and around 13:02 IST (07:32 UTC), again the Western and Northern regions separated, with power circling through the Eastern region grid. However, unlike the previous day, the phase shift between the Northern and Western region grids extended into the Eastern region. Rather than separating from the overloaded Northern grid, the Eastern grid instead separated from the Western region, from which it had imported power. Then the disaster continued along similar lines to the previous day: the Northern grid remained overloaded and the underfrequency load-shedding scheme failed to act.25–27 As a result, power stations across the affected parts of India went offline.

Shrivastava, A. Velayutham and A. S. Bakshi. It examined the causes of the blackout, and practicability of ensuring continued rail services during grid collapse, and issued its report on 16 August 2012. The committee found multiple systemic factors that predisposed the grid to collapse. In general, utilities appeared to have invested little in blackout prevention, or done so pro forma. Power dispatch centers had insufficient monitoring tools to manage power flows, and used unreliable cell phone services to communicate with power plant control centers.35,37–39,46,62 Any islanding schemes appeared nonfunctional.36–37 Power stations appeared to have had adequate generation capacity to avoid the blackouts, but had (contrary to regulations) not implemented droop speed control on their governors, or set it aggressively enough.12,27,36–37 Many heavily loaded transmission lines appeared to have inadequate parallel power storage facilities, such that an underload at one end might appear as an overload at the other. Rather than installing power storage, many utilities had simply removed the transmission lines from service.28,37 Local distribution networks also appeared overtaxed, forcing power flows onto the bulk power distribution system unnecessarily.38 The committee also suggested that contracts in the Indian legal system misrepresented the physics of the electrical grid. Utilities unexpectedly drawing power from their neighbors did not have to compensate those neighbors for the power. Consequently utilities only declared expected flows to avoid regulatory fines. However, regulators incorrectly believed that they lacked legal authority to decrease the official capacity of failed grid segments in real time.33–35 The proximate cause of the blackouts was the multiple existing outages (both scheduled and forced) that had limited inter-regional power transmission corridors on the days of the failures. These induced high loading on 400 kV Bina–Gwalior–Agra link, such that the grid could not survive loss of that link. The blackout then occurred when grid operators failed to reduce loading on the link and the link's protection system mistakenly removed it from service.http://www.powermin.InvestRpt/pdf/GRID_ENQ_REP_16_8_12.pdf Report of the Enquiry Committee on Grid Disturbance in Northern Region on 30th July 2012 and in Northern, Eastern & North-Eastern Region on 31st July 2012 16 August 2012 powermin.InvestRpt 28 August 2012 2 November 2012 https://web.archive.org/web/20121102122454/http://www.powermin.InvestRpt/pdf/GRID_ENQ_REP_16_8_12.pdf dead The committee also noticed that the grid appeared to have insufficient black start capability, requiring two separate rounds to bring all power plants on line. Conversely, power plant protection systems appeared insufficiently aggressive, as separation from the grid under high load had physically damaged the machinery in multiple thermal power plants. However, delays in restarting the grid appeared to arise from constraints other than physical, as gas turbine power plants had also required an unduly long start-up time.48–49,56 The investigation also refuted rumors that the grid had been brought down by a cyberattack.59,61 See also India Energy Electricity sector in India Northeast blackout of 2003 2003 Italy blackout Power outage 2019 Java blackout 2026 Sumatra blackout References ABC News http://abcnews.com/International/wireStory/electricity-grids-fail-half-india-16899933 Indian Businesses Weather Blackouts, but at a Cost 1 August 2012 3 August 2012 United States Associated PressSeptember 2019 InternetArchiveBot yes BBC News https://news.bbc.co.uk/2/hi/south_asia/1096957.stm Massive power cut hits India 2 January 2001 18 March 2015 The Economic Times https://economictimes.indiatimes.com/news/news-by-industry/energy/power/power-grids-fail-power-restoration-complete-in-delhi-north-east-50-in-eastern-region/articleshow/15293178.cms Power grids fail: Power restoration complete in Delhi & North East, 50% in Eastern region 31 July 2012 31 July 2012 Gardiner Harris Vikas Bajaj https://www.nytimes.com/2012/08/02/world/asia/power-restored-after-india-blackout.html?_r=1&pagewanted=all limited As Power Is Restored in India, the 'Blame Game' Over Blackouts Heats Up 1 August 2012 2 August 2012 The New York Times Rajesh Kumar Singh Rakteem Katakey 1 August 2012 Worst India Outage Highlights 60 Years of Missed Targets https://www.bloomberg.com/news/2012-08-01/worst-india-outage-highlights-60-years-of-missed-targets-energy.html 2 August 2012 Bloomberg Tripti Lahiri How Many People Actually Lost Power? https://blogs.wsj.com/indiarealtime/2012/08/01/how-many-people-actually-lost-power-in-india/ The Wall Street Journal 1 August 2012 5 August 2012 https://web.archive.org/web/20200812080752/https://blogs.wsj.com/indiarealtime/2012/08/01/how-many-people-actually-lost-power-in-india/ 12 August 2020 India real time Ajay Malhotra Associated Press http://www.moneycontrol.com/smementor/news/indian-markets/how-businesses-pay-for-indias-unreliable-power-system-739304.html How businesses pay for India's unreliable power system 2 August 2012 3 August 2012 SME Mentor moneycontrol.com 1 February 2014 https://web.archive.org/web/20140201183914/http://www.moneycontrol.com/smementor/news/indian-markets/how-businesses-pay-for-indias-unreliable-power-system-739304.html dead Sujay Mehuddia Smriti Rak Ramachandaran 30 July 2012 Worst outage cripples north India https://www.thehindu.com/news/national/worst-outage-cripples-north-india/article3702075.ece 30 July 2012 https://web.archive.org/web/20121117052357/http://www.thehindu.com:80/news/national/article3702075.ece?homepage=true 17 Nov 2012 National live The Hindu Outlook India's Mass Power Failure Worst Ever in World History http://www.outlookindia.com/news/article/indias-mass-power-failure-worst-ever-in-world-history/770631 Press Trust of India 1 August 2012 1 August 2012 dead https://web.archive.org/web/20160117172606/http://www.outlookindia.com/news/article/indias-mass-power-failure-worst-ever-in-world-history/770631 17 Jan 2016 Helen Pidd https://www.theguardian.com/world/2012/jul/31/india-blackout-electricity-power-cuts India blackouts leave 700 million without power 31 July 2012 India 31 July 2012 The Guardian Hriday Sarma Ruby Russell https://usatoday30.usatoday.com/news/world/story/2012-07-31/india-power-outage/56600520/1 https://web.archive.org/web/20200727072203/https://usatoday30.usatoday.com/news/world/story/2012-07-31/india-power-outage/56600520/1 27 July 2020 Second day of India's electricity outage hits 620 million 31 July 2012 Gannett USA Today External links Official report of the enquiry committee https://web.archive.org/web/20121102122454/http://www.powermin.InvestRpt/pdf/GRID_ENQ_REP_16_8_12.pdf 2 November 2012 Category:2012 disasters in India Category:2012 industrial disasters India Category:Electric power in India Category:July 2012 in India Category:2012 in Indian economy
