NEW DELHI —
About 600 million people lost power in India on Tuesday when the country’s
northern and eastern electricity grids failed, crippling the country for a second
consecutive day.
The outage stopped
hundreds of trains in their tracks, darkened traffic lights, shuttered the
Delhi Metro and left nearly everyone — the police, water utilities, private
businesses and citizens — without electricity. About half of India’s population
of 1.2 billion people was without power.
India, however, has an
unofficial power grid in the form of huge numbers of backup diesel generators
and other private power sources. That kept electricity flowing in everything
from private residences and small and large businesses to hospitals and major
airports.
Manoranjan Kumar, an
economic adviser with the Ministry of Power, said in a telephone interview that
the grids had failed and that the ministry was working to figure out the source
of the problem. The northern and eastern grids cover 11 states and the capital
city of Delhi, stretching from India’s northern tip in Kashmir to Rajasthan to
West Bengal’s capital of Kolkata.
The failure happened
without warning just after 1 p.m., electric company officials said.
“We seem to have plunged
into another power failure, and the reasons why are not at all clear,” said
Gopal K. Saxena, the chief executive of BSES, an electric company that services
South Delhi, in a telephone interview. It may take a long time to restore power
to north India, he said, because the eastern grid has also failed, and
alternate power sources in Bhutan and the Indian state of Sikkim flow into the
east first.
About two hours after
the grid failure, power ministry authorities said some alternate arrangements
had been made. “We are taking hydro power from Bhakhra Nangal Dam,” in northern
India, said Sushil Kumar Shinde, the power minister, in a televised interview.
India has struggled to
generate enough power of its own to fuel businesses and light homes, and the
country relies on huge imports of coal and oil to power its own plants. But
supply and demand may not explain away this week’s grid failures, power executives
said.
The failure on Tuesday
affected roughly twice as many people as the massive power outage the previous
day, when the northern power grid failed and left more than 300 million people
without power for several hours. No official reason for the Monday’s failure
has been given, although some local news reports pointed fingers at state
governments which were overdrawing power.
That assessment is too
simplistic, Mr. Saxena, of BSES, said. There are controls in place on India’s
electricity grids that override an outsized power demand. “We have one of the
most robust, smart grids operating” in the world, he said. It would “not be
wise” to give an assessment of what happened at this time, he added.
Institutions without a
private backup system were shuttered. All trains stopped in the Delhi Metro,
which carries nearly 2 million passengers a day. Trains were pulled to the
closest stations using battery back up, and then evacuated, a spokeswoman for
the Delhi Metro said, and the stations have been locked. “We had never
anticipated such a thing,” the spokeswoman said.
A trade body, the
Associated Chambers of Commerce and Industry of India, or Assocham, said that
Monday’s power problem “totally disturbed the normal life and has severely
impacted the economic activities."
“While on the one hand
it is a pity that over 26,000 megawatts of power stations are idle due to the
nonavailability of coal, on the other one grid failure has brought the system
collapsed,” said the group’s secretary general D.S. Rawat, noting that “the
entire power situation at present is headed for disaster.”
Privatisation of
electricity and Monsoon deficit take the toll! World`s Biggest Black Out!
Entire Northern, North Eastern, Western and Eastern power girds
collapsed!Leading to power failure in several States of the country affecting
hundreds of millions of people.
By

Yes, it is the world`s
Biggest Balck Out! A massive power failure hit India for the second day running
as three regional power grids collapsed, blacking out more than half the
country. Hundreds of miners were trapped underground in the eastern state of
West Bengal when the lifts failed, metro services came to halt temporarily in
the capital and hundreds of trains were held up nationwide. The whole Northern
Grid collapsed yesterday for over six hours. From Rashtrapati Bhavan to small
villages in the nine states of North India, there was no power during that
time. Restoration has been slow. There was a blackout everywhere in hospitals, hotels, schools, colleges or homes etc. 'The last time the Northern Grid had collapsed
was in early 2001, on a cold day of the season. Then, I was the chairman of the
Central Electricity Regulatory Commission (CERC), created in 1998' - the first
Chairman of the Central Electricity Regulatory Commission writes.
For the second day in a
row, North India found itself without power. This time, the extent of the
crisis was much worse - the East, West and even North East were affected
too. The northern, north eastern, western and eastern grids tripped on Tuesday,
leading to power failure in several States of the country affecting hundreds of
millions of people. While the northern grid collapsed for the second time in two
days, the eastern transmission lines too failed on Tuesday afternoon, said
officials at the Power Ministry and electricity companies. Power supply was
disrupted in Delhi, Uttar Pradesh, Haryana, West Bengal, Assam and Punjab,
among other States.hose in Government find it easiest to pass the buck. The
states blame the Centre. The Centre blames the states. Power is on the Concurrent
List of the Constitution. Both the Centre and states must share the blame.The
responsibility for distributing available power inefficiently falls on the
states.The Central Electricity Authority (CEA), the main advisory body to the
Union power minister, has set a target of 100,000 MW of additional power
generation in the 12th five-year plan between 2012 and 2017. That
is what is needed to meet the power demand of an economy forecast to grow at 9
per cent per annum. The Planning Commission accepts this target but Environment
Ministry does not, which says that the target is "ecologically
unsustainable". The fallout of the nuclear accident in Japan means that
thermal power is back at the forefront. Hydro power continues to flounder
because of concerns over rehabilitation and resettlement.
This seems to be a
greater conspiracy as the Private companies managing Electricity often
blackmail the government for hike in tarriffs to boost their profit.
Deregulated electricity has the same story worldwide. For instance, the Company
managing Electricity in New Delhi is garnering enough profit since 2008.
Despite this, the prices were modified in favour of the company. But the
company wants more. It is very common to bargain for higher rates showcasing Power
crisis. What happened exactly. Mind, you, the government faced calls for urgent
reform of the power sector Tuesday, after a monster blackout triggered the
collapse of the entire northern grid, affecting more than 300 million people.
Leading the high-decibel reform choir were business lobby groups who said
Monday's outage -- the worst to hit the country in a decade -- underlined the
government's inability to address India's perennial electricity
shortfall.
"The north,
northeastern and the eastern grids are down but we are working and we will have
them restored shortly," Naresh Kumar, a spokesperson at the Powergrid
Corporation of India, told AFP.
Federal Power Minister
Sushilkumar Shinde told reporters that the monster outage, which struck in the
middle of the working day, was caused by states drawing power "beyond
their permissible limits."
There appeared to have
been a domino effect, with the northern grid drawing too heavily on the eastern
grid which in turn led the northeastern grid to collapse.
"Half the country
is without power. It's a situation totally without precedent," said Vivek
Pandit, an energy expert at the Federation of Indian Chambers of Commerce and
Industry.
Privatisation of
electricity and Monsoon deficit take the toll!Grid failure hit India for a
second day on Tuesday, cutting power to hundreds of millions of people in the
populous northern and eastern states including the capital Delhi and major
cities such as Kolkata.Privatization is the means to introducing competition in
the electricity market, not an end in itself. Genuine competition would imply
that electricity consumers are actually free to choose from competing service
providers: this is simply not the situation in case of franchisees.In some of
the states, it has been decided to hand over the urban feeders to the
franchise!Is privatization is the solution to the ailing power sector. This
seems to be a question needing a thorough analysis and transparent intention of
the government. Any thing done in the good spirit will yield fruits, but if
intention is not good the success of any attempt is doubtful. The loss in the
urban feeder is much less as compared to the losses in rural feeders. The
government should impose a pre condition that the revenue input based franchisee
interested in taking up urban substation should also take proportionate rural
feeder on the revenue input based franchisee basis. The electricity utility is
required to generate return on equity to be decided by CERC, this was 14% for
the tariff year 2008-09 but this was not taken into account by the UPERC while
arriving at the tariff due to poor performance of this sector. Return on equity
measures a corporation’s profitability by revealing how much profit a company
generates with the money shareholders have invested.
In economic terms,
electricity (both power and energy) is a commodity capable of being bought,
sold and traded. An electricity market is a system for effecting purchases,
through bids to buy; sales, through offers to sell; and short-term trades,
generally in the form of financial or obligation swaps. Bids and offers use
supply and demand principles to set the price. Long-term trades are contracts
similar to power purchase agreements and generally considered private
bi-lateral transactions between counterparties.
Wholesale transactions
(bids and offers) in electricity are typically cleared and settled by the
market operator or a special-purpose independent entity charged exclusively
with that function. Market operators do not clear trades but often require
knowledge of the trade in order to maintain generation and load balance. The
commodities within an electric market generally consist of two types: power and
energy. Power is the metered net electrical transfer rate at any given moment
and is measured in megawatts (MW). Energy is electricity that flows through a
metered point for a given period and is measured in megawatt hours (MWh).
Markets for energy
related commodities are net generation output for a number of intervals usually
in increments of 5, 15 and 60 minutes. Markets for power related commodities
required by, managed by (and paid for by) market operators to ensure
reliability, are considered ancillary services and include such names as
spinning reserve, non-spinning reserve, operating reserves, responsive reserve,
regulation up, regulation down, and installed capacity.
In addition, for most
major operators, there are markets for transmission congestion and electricity
derivatives, such as electricity futures and options, which are actively
traded. These markets developed as a result of the restructuring of electric
power systems around the world. This process has often gone on in parallel with
the restructuring of natural gas markets.
I don`t know how to work
today. We suffered Load shedding already. and now Electricity may go off
anytime.AsThe entire northern and eastern power girds collapsed on Tuesday
afternoon, knocking off electricity in the entire metro services have come to a
halt in Delhi, West Bengal, Jharkhand, Bihar and Orissa.
NTPC, as the principal
generator supplying the northern states, did not cut generation. PowerGrid, the
inter-state transmission utility that controlled the state load dispatch
centres and had moment-to-moment information on demand and supply of power, was
not alert enough to take corrective action.
The central government,
which owned NTPC and had determined its tariffs and incentives, gave it an
incentive to produce at more than its plant load factor of 64 per cent. This
was because the imperative in those years (as it is now) was to generate as
much electricity as possible. But NTPC was already producing at 80 per cent
plant load factor (PLF) and was earning incentives without any special effort.
Any backing down of generation by NTPC would have meant serious loss of
earnings. So, it kept pumping electricity on to the grid, even as demand was
low. This led to the frequency soaring and the grid’s collapse.
The Delhi Metro came to
a standstill yet again on Tuesday afternoon after services were suspended for
two hours due to collapse of the Northern Power Grid for the second consecutive
day.Traffic was thrown out of gear in the capital this afternoon when signals
went blank following power failure across north India.
Huge traffic jams were
reported from various parts of the capital, including Connaught Place, ITO,
Ashoka Road, India Gate and Laxmi Nagar.
Mamata blames Centre for
Grid failure but says will work with Centre to get past the crisis.
- Chief Minister of West
Bengal Mamata Banerjee announces a holiday in the state to enable people to
reach their homes safely in the wake of Eastern Grid failure.
The failure of
North-Eastern grid has affected power units of Damodar Valley Corporation in
Jharkhand with several parts of the state going without electricity.
"Several units
ceased to work following the failure of North-Eastern Grid section," DVC
Chief Engineer (Chandrapura power unit) R Basuri said.
Mizia Thermal Power,
Durgapur Thermal Power, Bokaro Thermal Power and Maithon Hydel Power in
Jharkhand and neighbouring West Bengal are under the DVC, he said.
The West Bengal
government on Tuesday declared a holiday in its offices after 3:00pm following
the grid failure to enable employees to return home early, especially those who
commute by train.
"We have taken a
decision to declare a holiday in state government offices after 3:00 PM so that
the employees can return home early in the absence of trains which are not
running due to power failure," Chief Minister Mamata Banerjee told
reporters at Writers' Buildings.
She said private offices
were also requested to declare a holiday similarly in the interest of
employees.
Stating that it might
take 10 to 12 hours for restoration of normal power supply, she asked TV
channels not to create panic over the issue.
Banerjee said she held
an emergency meeting and spoke to the Railways to restart normal services
within two to three hours and to see if trains could be run with diesel engines
in the suburban sections.
The chief minister said
Metro Rail services in Kolkata were unaffected.
Transport arrangements
were being arranged for people by bus and lorry, she said.
Banerjee said the state
government was not responsible for the power failure and that it was the
fallout of the power outage in the northern grid.
"The crisis started
from northern India with the failure of the mother grid and after the trippings
there, a complex situation developed which impacted the eastern grid affecting
all parts of the state, besides Bihar and Orissa," she said.
She said that a
monitoring committee was formed led by private power utility, CESC limited.

For the second time in
two days, half of India plunged into darkness after the Northern and the
Eastern Grids collapsed, affecting all seven states in the north and the states
of Sikkim, Assam, West Bengal, Bihar, Orissa and Jharkhand in the
It's peak summer
in most parts of India. Demand for power is at a peak of 2,17,000 mega watt.
Our power generation, however, is much less at 1,99,877 mega watt. Poor
transmission and distribution makes it even worse.
Many cities such as
Chennai, Bangalore and the capital itself, Delhi, have long power cuts.
Forty per cent of the
country does not get electricity at all. About six lakh villages do not have
any network to receive electricity.
