Thought of doing a year wise summary of new power generation from Tuticorin

2010 - 189 MW from IBP-1
2011 - None
2012 - 1460 MW (600 MW from CE-Ph1/Unit 1; 700 from IBP-2, 160 from Sterlite)
2013 - 1600 MW (1000 MW from NLC Tuticorin, 600 from CE - Ph1/Unit 2)
2014 - None
2015/16 - 4520 MW (1600 from CE-Ph 2/Unit 1&2, 1600 - TNEB/BHEL Udangudi, 1320 from IBP-Manapad)
1000 MW from SPIC - not sure when this will come up.

So with this picture it seems that in 2015 we look to be self sufficient.

- Good news is boilers are delivered, so if work goes on full swing we can see it operational by end 2012 or begining 2013. Optimistic target of mine is 2013

Coastal Energen - Phase 1 - 2 X 600 MW
- Work proceeding very well, first unit will be operational in a year, and the 2nd unit will be another year from then
- But as per their power purchase agreements, most of the power is going to Western India bought by Tata power.


Coastal Energen - Phase 2 - 2 X 800 MW
- Documentation for approvals is in progress. Expected in another 5 yrs

Ind Barath - Plant 1 - 3 X 63 MW
- Operational

Ind Barath - Plant 2 - 2 X 270 MW
- Progress is good, chimney work is nearing completion, boiler is lifted and fitted.. Should begin operations in a year

Sterlite - Captive Plant - 2 X 80 MW
- Progress is okay, should begin operations in a year

SPIC - 1 or 2 X 525 MW
- Documentation work is in progress , 5 yrs to go if they decide to go ahead

Ind Barath - Manapad - 2 X 660 MW
- Documentation work is in progress
- Target Date is 2015

TNEB - BHEL SuperCRitical Power Plant - 2 X 800 MW
- Documentation work is in progress
- Target Date is 2015

more than half of this is private power and the PPA agreements of private players will be with other states also so IMO TN will get 20-30% of power from private players..also the central govt projects(NLC and NTPC/BHEL) will supply only 35% of power to TN

But won't TN be getting power from govt projects in Kar, Andhra, Maha et all??

But the Demand will expand more rapidily than supply. We will require 20000 MW in the coming years

I know that factor of PPA of private players need not be with TN customers...however the projects listed would contribute more than 70% to TN customers. The details are as below.

Total of 7769 MW capacity power plant work is now going around Tuticorin.

- 189 MW from Ind Barath is sold to TNEB
- 160 MW from Sterlite is for their own use at their Tuty plant. Hence they will not use TNEB power which is saving for TNEB
- 1000 MW NLC plant is a JV with TNEB and it is fully for TN and not a Central Govt project
- 1600 MW is the BHEL-TNEB JV and it is fully for TN.
- 700 MW of CE Ph1 will go to TATA power, and the rest 500 MW will be for TN

So confirmed 3449 MW

- 1600 MW of CE ph2 PPA are not signed off and most likely to be TN customers as CE is doing roadshows in Coimbatore region
- 700 MW of Ind Barath - I have no idea
- 1320 MW of Ind Barath - I have no idea.

From all their old plants in TN, Ind Barath has sold their power to TN,

Hence I can give 100% from the above 3 plants, but even if I give 50% of these plants to sign up TN customers, it will give 5259 MW out of 7769 MW, that is around 68%. In case of 100% of power sold to TN, then it around 90%.

This is the reason I provided update that the plants coming up around Tuticorin would assist in resolving the power crisis in TN by 2015

The current gap is around 3000 - 4000 MW, everyone understands that the demand is going to increase over the years, however the problem of power shortage started becoming acute since 2008. A normal power plant to come up takes around 5-6 years from the day of initiation. So from 2008 - 2015 there are 7 years and I certainly hope 7 years is a good enough time for a power shortage problem to be rectified.

I had given an update on power plants around Tuticorin only whose work has started and on conservative numbers we will be getting more than 5000 MW by 2015 from Tuticorin region itself. Then there is Chennai region, Cuddalore/Nagapattinam region, Mettur, NLC and Koodangulam and if everything is taken into consideration we should be self sufficient by 2015.

Preparations under way for hot run of Kudankulam nuclear reactor



Things are getting set for the commissioning of the first unit of 1000 MWe of the Kudankulam Nuclear Power Project (KKNPP) in Tamil Nadu by the end of September or in October this year. Preparations are under way for the hot run of the reactor, an important activity that will take place before the reactor is loaded with the real fuel assemblies made of enriched uranium.

Pre-commissioning activities of the second reactor at the KKNPP, also of 1000 MWe capacity, have already started. It will reach criticality about nine months after the first reactor does so.

The two reactors are Russian ones that belong to the advanced design of VVER family but have been built by the Nuclear Power Corporation of India Limited (NPCIL). These are the biggest reactors to be built in India. They use enriched uranium as fuel, and light water as both coolant and moderator.

“The clearance for starting the hot run of the first unit is expected shortly. The hot run itself will start in some days,” said M. Kasinath Balaji, Site Director, KKNPP. The hot run will continuously last about three weeks and it will be completed by the end of June. It will entail heating the primary coolant water to the reactor's operating temperature of 280 degrees Celsius. “We will be operating the reactor systems at the temperature at which the reactor will operate when it has real fuel bundles,” he said.

Dummy fuel assemblies

The process of hot run will take place with the dummy fuel assemblies, which were loaded into the reactor several months ago. The dummy fuel assemblies have the same configuration as the real fuel assemblies but have no enriched uranium inside. The reactor vessel houses the 163 fuel assemblies inside.

Right now, the KKNPP engineers are preparing the reactor (the first unit) with the dummy fuel inside and the control rod drives installed, for conducting hydro tests at a pressure of 180 kg per sq. cm. as per the standard operating procedure. A hydro test done in December 2010 at 250 kg per sq. cm validated the strength of the reactor vessel and the primary coolant circuits. The control rod drives, which shut down the reactor in an emergency, were installed subsequently. The test at a pressure of 180 kg per sq. cm. will be done in a few days. After these tests are done, clearance for the hot run is expected.

“Hot run means taking the temperature of the primary coolant water to the operating temperature of 280 degrees Celsius with the help of energy from the primary coolant pumps,” Mr. Balaji said. There are four primary coolant pumps, each requiring 6.3 MWe. During the hot run, three primary coolant pumps will be running and they will circulate the water through the dummy fuel assemblies. All safety systems will be tested.

Robotic inspection

After completion of the hot run, Mr. Balaji said, the reactor would be disassembled and the control rod drives removed. The cover of the reactor would be opened up and the dummy fuel assemblies inside the reactor vessel removed. Then the reactor vessel, the main coolant pipelines and all associated systems would be inspected for their integrity using highly sophisticated robotic machines. “These robotic machines have been tested in a mock-up facility and they are ready to carry out inspection operations inside the reactor once the hot run is completed. These inspection operations will last about a month,” said Mr. Balaji.

The results of the hot run and inspection by the robotic machines will be reviewed by the Indian specialists along with their Russian counterparts.

After further review by the regulatory authorities, the KKNPP officials will make a request to the regulatory authorities for loading the real fuel assemblies into the reactor. The first fuel assemblies will be loaded in the beginning of September and after all the 163 fuel assemblies are loaded, the approach to its criticality will begin. The reactor will reach criticality by the end of September or the beginning of October. After a few weeks of low power experiments, electricity will be wheeled into the grid. Nine months later, the second unit will be started up.

From the two units with a total capacity of 2,000 MWe, Tamil Nadu's allocation will be 925 MWe, Karnataka 442 MWe, Kerala 266 MWe, Puducherry 67 MWe and the unallocated is 300 MWe.

Safety features

The Kudankulam reactors have state-of-the-art safety features in terms of the various passive safety systems backing the active safety systems. Twelve huge water tanks are installed inside the reactor building to ensure that the reactor is filled with water with boron in case of loss of water from the reactor fuel core. In addition, the reactor is cooled by way of natural circulation of air in the event of loss of electricity supply. Each reactor at Kudankulam is provided with four diesel generators of 6.3 MWe capacity each. Of the four diesel generators, only one is required to keep the reactor in a cool state under shutdown condition. The diesel generators were installed at a height of nine metres above the mean sea level, isolated from tsunami-like floods, Mr. Balaji said.

hmm.. thanks for the break up..

if TN's demand is 14,000 MW today...now assuming 10% growth for next 5 yrs we get demand at 22,500 MW.. and we will get supply of 8,000 MW max.. today's supply is around 10-11,000 MW so total supply will be around 20,000 MW max(i am including renewables as well)..

So there can be a deficit of around 2000 MW by 2015 which will be around 10% of total demand by that time.. still high IMO

and i am assuming 8k MW because i am hoping that the govt. projects(BHEL and NLC) will be delayed as usual!

SSCaddict,

Blackpearl have given the break up only for Tuticorin power hub area.

FYKI 3500MW of power would be available for TN by next year mid from u/c thermal power plants at Mettur, Chennai, Neyveli etc., also TN's Koodankulam share.

Lot of private power projects is set to kick off at Nagapattinam too. These number exclude the capative power plants of TN industries, wind farms and solar power plants. TN would become power surplus by 2016.

[Arul Murugan]

SSCaddict,

http://www.tneb.in/template_3.php?te...d=0&subcid=167

FYKI 6000MW will be added to TN grid by TN gvt and its JV project by 2016 (considering all those gvt delays).

In this 1600MW overlaps with Blackpearl's 7800WM as it is planned by TNEB JV.

6000MW of TNEB+JV + 6200WM from private at Tuticorin = 12200MW by 2016.

--------------------------------------------------------------------------
Projects in pipeline for furture needs

1. Ennore SEZ thermal - 1600MW -2015 comm planned i guess it will be dragged in 2018-2020

2. NCTPS Stage III 800MW - planned 2015, may get dragged to 2018-2020

3. Nagapattinam Mega power plant - 4000MW - 2017 planned, may drag for 2022

4. Cheyyur Mega power plant - 4000MW 2017 planned, may drag for 2022

5. Thiruvadanai power plant - 1600MW planned for 2015 comm, may drage for 2018-2020

6. Uttrakosamangai - 1600MW planned for 2015 comm, may drag for 2018-2020.

By 2023 another 13600MW.

Again this all includes the renewable energy planned in the state.

Both DMK and ADMK learnt bad lesson for not planning it properly. So they will never repeat the same problem again.

[SSCaddict]

hmm.. thanks for clarification arul

so by 2016

* Demand=25,000 MW

* Supply=10,000(as of now) + 12,200(as you said) + 2000-3000 MW(from PPA agreements with states) =24,200-25,200 MW

so approximately it may be fine but at peak hours there may be power cuts

[Arul Murugan]

Renewable wind mills which is not considered in above equations, capitive power plants will cover this shortage.

Only one check! previous gvt didn't even supervise any of the power project, none of the politician visited the project sites! If present gvt repeat the same mistake(i.e lethargic in comm/execution) then shortage and peak hr power cut will be there.

[BlackPearl]

Power cuts started in TN in 2008. A thermal power plant takes around 5-6 years to become operational from the start day of planning.
- 3-6 months of conceptualization
- 1 year for land acquisition
- 1 year for approvals
- 6 months for securing financial closure
- 3 years from zero date of construction
So a total of 6 years for a new project on a new site. Expansion on existing site will reduce the land acquisition duration.

So by 2015-2016 which is around 7-8 years TN should have more supply than demand. If you go through the first page the total capacity addition is around 63,000 MW, but certainly most of them will not go ahead. But atleast 20,000 MW will materialize. In that list of 63,000 MW, Tuticorin region contribution is around 9000 MW out of which work is going on for 7800MW. Out of remaining 50000 +MW if half of them becomes operational we will be doing great.

2015-2016 is still a long way to go... business' outside Chennai have felt the pinch of power cut and they have either completed or in the process of putting up of captive / cogeneration power plants. Certainly they are not going to wait until 2015, nor wanted to put their trust in Govt to create this infrastructure for them, they wanted to run their business and they will definitely find their way to run business.
Large industries are going for thermal power plants which includes Sterlite (160MW), India cements (48 MW), ARS Metals (120 MW), Suryadev Alloys (120 MW) and many others. Small and Medium Sized Enterprises go in for bio-mass plants and wind mills. Sugar plants are building co-gen plants. Similarly Business are facing shortage of water and now almost all major industries are putting up their own desalination plants. Well retail consumers like us, buy invertors and solar panels and generators and dont wait for govt to solve problems.. so industries will all the more create this infrastructure.

Indirectly this will assist in Govt solving the issue.

The situation will start to improve in 2013 and well before the elections in early 2016 , it will become surplus situation.. the present Govt also knows that if they dont set it right, they will not come to power again.

this is my opinion about the power situation in TN.

Cheers!!!

Bhavani Hydro Electric project by August

S. Ramesh

ERODE: The 30 MW Barrage II of Bhavani Kattalai Hydro Electric Project at Vendipalayam here will become operational soon.

The Tamil Nadu Generation and Distribution Corporation (TANGEDCO) has completed almost all the works for the barrage. The testing procedures are likely to begin on June 25.

“We will be storing water up to five metres in the barrage for the initial rounds of testing. The level will be increased to nine metres, which is the full capacity of the barrage, by the end of July and test all the power generation equipment in the barrage,” a senior official in the Corporation told The Hindu.

The barrage, constructed across the Cauvery River, is one of the major power generation projects taken up by the TANGEDCO in this part of the State. The Corporation had allotted Rs. 400 crore for the project initially. Later, the total cost of the project was revised to Rs. 495 crore. Two power generation units, each with a capacity of 15 MW, have been installed in the barrage.

The construction of the barrage began in February 2006 and the Corporation had planned to complete the works within 36 months. But it was delayed at various stages of implementation due to different reasons.

“Now we have completed almost all the works and are getting ready for testing the equipment. The project will be operational by the end of July or in August this year,” officials said.

Supposed to be commissioned by Feb 2009... delayed due to in-efficient admin of previous gvt. 30MW would help the textile belt.

[N.kumar]

Blaming the previous DMK government for the power cuts in the state, Tamil Nadu Chief Minister J Jayalalithaa today said her government would create an additional capacity of 10,000 MW in the next five years and make it a power surplus state.

The DMK government did not implement various power generation programmes sanctioned by her government during 2001 to 2006, which had resulted in power shortage, Jayalalithaa said replying to the debate on the motion of thanks to the Governor for his address to the state assembly.

She said during 2001-2006, Tamil Nadu was free from power cuts. "We will attain more installed capacity making surplus power during our period", she said.

Improper maintenance or no maintenance of thermal power plants during the DMK regime also led to shortage, she added.
