NLC to add 80 MW of wind, solar power

Quote:
Chennai, May 30:

Public sector Neyveli Lignite Corporation will enter the renewable energy area this year. The company expects to add 50 MW of wind power and 30 MW of solar before March 2014. The tendering process for the 50 MW wind farm is on and the vendor could be finalised in a month, R. Kandasamy, Director (Planning & Projects), said. The wind farm is coming up in the Tirunelveli district of Tamil Nadu.

Kandasamy said the Tamil Nadu Electricity Board had assured NLC that there would be no problems in evacuating the power. Tendering is also on for a 10 MW solar plant that will come up on the NLC campus in Neyveli. This will help the company meet its ‘solar purchase obligation’ mandated by the Tamil Nadu government.

New proposals increase solar project capacity to 690 MW ( Source: THE HINDU)


Even about a month ago, it looked as if the State government’s Solar Energy Policy was able to attract only a modest number of project proposals with capacity of 260 MW.

But, in the last few weeks, the Tamil Nadu Generation and Distribution Corporation (Tangedco) received letters of commitment from many developers for capacity addition or fresh projects to such an extent that eventually, the quantum of capacity of projects rose almost two-and-a-half times.

At 5 p.m. on Friday when the deadline for submission of proposals ended, 23 more developers formally conveyed their willingness to put up new projects. Along with proposals for capacity addition, the total quantum of capacity rose to 690 MW.

Till early this month, the number of developers sanctioned was 30. Now, the Corporation has issued Letters of Intent (LoI) to a total of 53 developers.

If one were to take into account the benchmark capital cost of Rs. eight crore per MW, as determined by the Central Electricity Regulatory Commission, all these projects would mean investments to the tune of Rs. 5,520 crore.

As the Tangedco is the agency to administer solar power obligations (SPO) under the Policy, it has been entrusted with the function of facilitating investors by procuring energy generated from their plants through 20-year-long power purchase agreements. In December last, the Corporation floated bids.

Explaining the sudden rise, an official says that when the Board of Directors of the Corporation had cleared the first batch of bidders in February, it had decided to give time to them as well as other bidders [who originally chose not to accept the Corporation’s terms on power purchase] to come back to the power utility if the bidders were agreeable to the terms. The deadline was then fixed as May 31.

Of the additional 430 MW, two companies have come forward to put up plants of 100 MW each. As regards the rest, the capacity varies from one MW to 10 MW to 25 MW to 45 MW to 60 MW. Tiruvannamalai and Ramanathapuram are among the districts where the new projects are to come up.

All these projects are expected to be commissioned by March next

Power woes due to coal shortage

Quote:



Visakhapatnam: NTPC’s Simhadri super thermal power station here has been unable to generate power optimally since a month due to the acute shortage of coal supply, which can only add to the state’s power woes.
According to NTPC Simhadri sources, the generation loss due to shortage of fuel supply has been 325 million units as on Monday. The state government depends heavily on NTPC Simhadri, which has four units, each with the capacity to generate 500 MW.

Four units were commissioned in two stages, with Stage-1 generating a total 1,000 MW and Stage-II 452 MW. Of the 1,000 MW produced from SHOULD BE STAGE I Stage-II, other states get power as per the Gadgil formula.

Tamil Nadu gets 233 MW, Karnataka 208 MW, Kerala 95 MW and Puducherry 12 MW. The unallocated power — 150 MW — is also shared by the southern states. During the current financial year (2013-14), Simhadri station, which is maintaining 100 per cent availability, could utilise only 87.69 per cent capacity due to fuel shortage.

The average domestic coal receipt as on Monday was 23,661 mt/day against a requirement of 28,000 mt/day. Simhadri station generated 1341 million units in April 2013, which is 92.83 per cent, by modulating the generation according to the receipt of domestic coal on a day-to-day basis.

NTPC gets coal from the Mahanadi coalfields, Singareni, Odisha and Indonesia. NTPC Simhadri last year signed an agreement for purchasing 4.5 lakh tonnes of low caloric coal from Indonesia for three months while the State government too agreed last year to supply 7,000 tonnes per day besides the early availability of 3,500 tonnes from Singareni Collieries Company Limited (SCCL).

The average day stock in April was 16,750 mt of coal. This situation further worsened during May as the average receipt of domestic coal dipped to 21,241 mt/day, restricting the station’s generation.
The average receipt of domestic coal in the last week of April was 20,375 mt/day, which is only 5.8 rakes per day and accounts for the monthly utilisation factor in May 2013 being 82.26 per cent only.

Wind is continously producing more than 60MU for past 10days and consumption also reduced by 10% due to monsoon initial rains.

State/Central power stations are taking advantage this time for maintenance slot!

I think you guys in TN SSC should discuss and make a set of ideas to revive and restore the ground water table and rivers in TN. That is going to be THE next greatest problem in the state.

CEA: 17 states to see substantial power shortages, south to be worst affected

Quote:

As many as 17 states are expected to witness significant power supply shortages this fiscal, with Tamil Nadu projected to receive less than three-fourth of its total electricity requirements.

Among the 17 states, the worst hit would be the three southern states of Tamil Nadu, Kerala and Karnataka.

Latest estimates from the Central Electricity Authority (CEA) show that the southern region — comprising four states and one union territory — is likely to see a power deficit of 19.1 per cent in 2013-14.

In signs that electricity supply is worsening in the southern region, the power deficit would be higher this fiscal compared to deficit of 15.5 per cent in 2012-13 period.

The projections come against the backdrop of acute power shortages in various parts of the country due to a slew of factors including fuel scarcity, poor financial health of discoms (state power distribution companies) and transmission woes.

Tamil Nadu, Kerala, Karnataka, Andhra Pradesh and Union territory of Puducherry make up the southern region.

While the deficit in Tamil Nadu is estimated to be around 26.5 per cent, the shortage in Kerala would be around 24.8 per cent, Karnataka (23.2 per cent) and Andhra Pradesh (9.1 per cent). Puducherry is projected to have a electricity supply surplus of 9.9 per cent.

Other states that are projected to see substantial electricity supply shortages include Punjab (19.7 per cent), Assam (19.7 per cent), Bihar (19 per cent), Uttar Pradesh (18 per cent), Arunachal Pradesh (17.7 per cent), Uttarakhand (15.4 per cent), Rajasthan (15.1 per cent) and Tripura (13.5 per cent).

As per CEA, the planning body for the power sector, Maharashtra with a deficit of 9.8 per cent, Goa (4.5 per cent), Jharkhand (6.8 per cent), Nagaland (5.6 per cent) and Orissa (0.8 per cent), are also among the 17 states that are expected to witness electricity shortages. The figures are based on the gap in supply and demand calculated on million units
Atleast the Central electric Auth ,comes and tell us , its bad times ahead..

Inter-regional grids to help evacuate more power to South

Quote:
HYDERABAD, JUNE 11: The commissioning of the Inter-regional power transmission line between Raichur–Sholapur 765 kV two single circuit lines will help Southern states of Andhra Pradesh, Karnataka, Tamil Nadu and Kerala access more power from west and northern region.

Indications are that the Raichur-Sholapur transmission line taken up with an outlay of Rs 1,930 crore last year and scheduled for completion by January is likely to be commissioned ahead of time, according to sources.

In addition to the Raichur-Sholapur line, three other inter-regional lines are under way. These include Kolhapur (new)-Narendra 765 kV double circuit line, Wardha-Hyderabad 765 kV double circuit line, and Angul-Srikakulam-Vemagiri 765 kv double circuit line.

The PowerGrid Corporation of India had, in the past, indicated that the country will have a single grid by 2014 with the commissioning of a new line that strengthens and interlinks west and Southern region.

All the southern States have sought additional power allocation from the Central generating stations to bridge the demand supply gap faced in the region.

CORRIDOR CONGESTION

The Government has initiated several steps to ease the corridor congestion which is hindering the supply of power from the surplus states in the North to South.

The inter-regional links between New Grid and Southern region grid and intra-regional links within the South would help mitigate the corridor congestion. They are under various stages of execution.

The inter-state transmission system within the southern region include links between Vijayawada-Nellore, Chittor-Thiruvalam, Kurnool-Thiruvalam, Madhugiri-Salem, Somanahalli-Salem, Salem-Somanahalli and Mysore-Kozhikode.

The Central Electricity Authority has received requests for additional power allocation by all the southern States. The demand varies from each State depending upon the period additional power supply has been sought.

Currently, while the Northern states of the country have access to power in the range of Rs 2.50-3/unit, the power-starved South is unable to access this power due to difficulty in transmission.

With the commissioning of Sholapur and Raichur line, the South would enable access to an additional 3,000 MW. This will also make the country a single frequency grid.

On one side, we talk of No or Low current, but in our area East Tambaram, we are suffering from excessive volts.

Past 2 weeks, 2 fans, 1 Tubelight, 1 LCD TV busssssssssssss. I am still keeping the LCD TV idle fearing Samsung's costlier spares in mind. Kalaingar TV doing duty till this high voltage crisis ends.

Is it advisable to head to samsung/ local LCD TV Mech for powerboard related problem?

Wind energy production up; load shedding down

Quote:
After reeling under eight-hour power cuts through April and May, people in the city have reason to rejoice now. The last 10 days have had very rare instances of power cuts, bringing cheer to residents and industries alike.
“The southwest monsoon has brought in its wake strong winds, facilitating higher production of wind energy,” said an official from the Tamil Nadu Generation and Distribution Corporation Limited, Madurai. “We are getting the energy supply from wind farms in Udumalpet, Theni, Tenkasi and Muppandal,” he added.

Before May 15, wind energy contributed to only about 10 per cent of the total power supply in Madurai. With the change in climate, it now contributes close to 25 per cent. While 7000 mega watts is the total installed capacity, close to 3000 mega watts are being supplied now. “We used to have power cuts in shifts of four hours till about two weeks back. But, for the last two weeks, the maximum power cuts we’ve faced has been for not more than 10 minutes,” said M. Chandrasekaran, secretary of the Nagari Industries Association.

He added that the 40-odd industries which were a part of the association could carry on production without interruption for the past two weeks in the absence of unprecedented power shutdowns.

“From 45 to 50 million units of load shedding per day, the figures have fallen to 15 to 10 million units. We have even had a few days without any load shedding,” said an official from the Tamil Nadu Electricity Board (TNEB).

While Tamil Nadu was receiving approximately 42 million units of wind energy per day in May, it had risen to more than 62 million units per day this month.

This had led to a decrease in dependency on hydro-electric and thermal power sources. While the usage of hydel power had fallen by an average of three million units, thermal power usage had fallen by approximately 20 million units per day. Power being harnessed through gas turbines have, however, remained constant at 5.5 million units to 7 million units per day and that of captive power plants stood at 26 to 32 million units a day.

The TNEB had also been importing energy from the Central Grid Sector to meet its energy needs. The suppliers include Madras Atomic Power Station (MAPS), National Thermal Power Corporation (NTPC), Kaiga Atomic Power Plant, and the Neyveli Lignite Corporation power stations, the sources added.

Higher capacity metallic fuel reactor at Kalpakkam being considered

Quote:
The Indian atomic energy establishment is mulling the option of going in for a higher capacity reactor powered by metallic fuel at Indira Gandhi Centre for Atomic Research (IGCAR) complex at Kalpakkam, a senior official said Friday.

"Setting up a fast reactor powered by metallic fuel is final. We are now discussing whether to go in for a higher capacity reactor than the 120 MW test reactor that was decided earlier," he told IANS, not wanting to be named.

He said there is not much of a difference in the reactor design of the 500 MW prototype fast breeder reactor (PFBR) that is under construction at Kalpakkam around 70 km from here, to be powered by mixed plutonium-uranium oxide (MOX) fuel, and the proposed metallic fuel reactor.

A fast-breeder reactor is one which breeds more material for a nuclear fission reaction than it consumes. It is the key to India's three-stage nuclear power programme.

The metallic fuel has better breeding ratio as compared to the MOX fuel, said an official.

The 120 MW reactor was thought of as the test bed for designing a 1,000 MW fast reactor to be powered by metallic fuel, a mix of 20 percent plutonium and 80 percent uranium.

According to an official, the research centre expects to receive the remaining sanctioned funds (total sanction Rs.25 crore) this year for carrying out preliminary studies.

He said the upward revision in the proposed reactor also changes many other aspects of the project like the entire fuel cycle of the reactor.

"The fuel assembly complex will be housed at the Kalpakkam complex instead of transporting it from some other place. The entire fuel systems will be co-located. Metallic fuel needs high preparation process," he said.

He said the existing 14 MW fast breeder test reactor (FBTR) is expected to serve the research needs for another 20 years and hence the question whether there is a need for another test reactor.

The proposed metallic fuel reactor will be the third reactor for IGCAR which already has a FBTR and a mini Kamini (Kalpakkam mini reactor) and the seventh one for the whole of Kalpakkam nuclear complex.

Two pressurised heavy water reactors (PHWR) of 220 MW capacity of Madras Atomic Power Station (MAPS) belonging to Nuclear Power Corporation India Ltd (NPCIL) are already functioning.

The 500 MW IGCAR designed PFBR is being built by Bharatiya Nabhikiya Vidyut Nigam Ltd (Bhavini).

A small light water reactor belonging to Bhabha Atomic Energy Centre (BARC) is also operational at the Kalpakkam nuclear complex.

With Bhavini planning to build two more 500 MW fast reactors sometime in the future, Kalpakkam nuclear complex will become one of the world's noted "island" of fast reactors, housing five units.

IGCAR officials expect the decision on the metallic fuel reactor to be taken soon, and construction is expected to begin in a couple of years.

Additional manpower would not be required for the proposed project as the existing resources would be sufficient.

Just yesterday evening I was thinking: 'Hmm....it is that time of the month when there is a KNPP start moved to the end of next month news.....' and now this is out!

NPCIL is reducing itself to a farce. This is a joke being played on the people of this country
