800 kV HVDC Substation under Execution by PGCIL near Kangeyam is ready and under commissioning tests.

ரூ.3,400 கோடியில் நவீன மின்நிலையம் முதல் முறையாக தமிழகத்தி்ல் தயாரானது


தென் மாநிலங்களில், முதல் முறையாக, தமிழகத்தில், 3,400 கோடி ரூபாய் செலவில், 800 கிலோ வோல்ட் திறனில் அமைக்கப்பட்டு வரும், அதிநவீன துணை மின் நிலையத்தின் கட்டுமான பணி முடிவடைந்துள்ளது.
மத்திய அரசின், 'பவர்கிரிட் கார்ப்பரேஷன்' நிறுவனம், பிற மாநிலங்களில் இருந்து, மின் வழித்தடங்கள் வாயிலாக, தமிழகத்தில் உள்ள, அதன், 765, 400 கிலோ வோல்ட் துணை மின் நிலையங்களுக்கு மின்சாரம் எடுத்து வருகிறது. அங்கிருந்து, அவற்றின் அருகில் உள்ள, தமிழக மின் வாரியத்தின், 400 கி.வோ., துணை மின் நிலையங்களில் மின்சாரம் பெறப்பட்டு, மின் இணைப்புகளுக்கு வினியோகம் செய்யப்படுகிறது.

துணை மின் நிலையம்


தற்போது, விழுப்புரம் மாவட்டம், அரியலுார் மற்றும் வட சென்னையில், 765 கி.வோ., திறனில், தமிழக மின் வாரியம் சார்பில், துணை மின் நிலையங்கள் அமைக்கப்பட்டு வருகின்றன.
சத்தீஸ்கர் மாநிலத்தில் இருந்து, தமிழகத்திற்கு, 6,000 மெகா வாட் மின்சாரம் பெறப்பட உள்ளது. இதற்காக, சத்தீஸ்கர் - ராய்கர் மற்றும் திருப்பூர் மாவட்டம் காங்கேயம் அருகில், தலா, 800 கி.வோ., வாட் திறனில், பவர் கிரிட் நிறுவனம், அதிநவீன துணை மின் நிலையம் அமைத்து வருகிறது. அவற்றை இணைக்கும் வகையில், அதே திறனில், 1,765 கி.மீ., துாரத்திற்கு, மின் கோபுர வழித்தடம் அமைக்கப்படுகிறது.



சோதனை முறை



இந்நிலையில், தற்போது காங்கேயம் அருகில் அமைக்கப்பட்டு வரும் நவீன துணை மின் நிலையத்தின் கட்டுமான பணிகள் முடிந்து, அவற்றில் உள்ள மின் சாதனங்களை, சோதனை முறையில் இயக்கும் பணி துவங்கியுள்ளது.
இது குறித்து, மின் வாரிய அதிகாரி ஒருவர் கூறியதாவது:பவர் கிரிட் நிறுவனம், 3,400 கோடி ரூபாய் செலவில், காங்கேயம் அருகில், துணை மின் நிலையம் அமைக்கும் பணியை, இரு ஆண்டுகளுக்கு முன் துவங்கியது. இதுவே, தென் மாநிலங்களில், அதிக திறனில் உடையது.

ராய்கர், காங்கேயம் இடையில் வழித்தட பணியும், 90 சதவீதம் முடிந்துள்ளது. விரைவில், அந்த வழித்தடம், ராய்கர், காங்கேயம் அருகில் உள்ள, 800 கி.வோ., துணை மின் நிலையங்களில் இணைக்கப்படும். இதனால், சத்தீஸ்கரில் இருந்து தமிழகத்திற்கும்; தமிழகத்தில் இருந்து பிற மாநிலங்களுக்கும், அதிக மின்சாரம் எடுத்துச் செல்ல முடியும்.இவ்வாறு, அவர் கூறினார்.

India's electricity demand falls for fourth straight month, here's why it matters

With the exception of Tamil Nadu in the country's south, demand fell in all large and industrialized states. Energy requirement fell across all regions in the country, the data showed

An official at Ministry of Power attributed the tepid electricity demand to an early onset of winter and high rainfall, which he said has reduced the need for air conditioning.

However, electricity demand from industries accounts for over two-fifths of India's annual electricity consumption, according to government data, with residences accounting for nearly a fourth and commercial establishments for another 8.5 per cent.

Kudankulam nuclear power plant: Steam generators for unit-4 ready

Rosatom State Atomic Energy Corporation, which is the main equipment supplier for Kudankulam nuclear power plant (KKNPP), has completed production of steam generators for the unit-4, the Russian firm said in a statement. In the nuclear power plant, heat is removed from the reactor core by coolant, which passes through the core. This thermal energy is used to produce water steam in the steam generator. Steam’s mechanical energy is supplied to the turbine generator where it goes into electricity.

The diameter of steam generators is over 4 m, length 15 m, and weighs 340 tonnes. The set of equipment for one power unit of a nuclear power plant of this type includes four steam generators.

Navigation season

Three generators were shipped to the Kudankulam nuclear power plant and the fourth item will be shipped in April 2020 when the navigation season is open, Rosatom said.“For effective interaction during production of equipment for KKNPP at Atomenergomash site, the permanent work of the Indian experts was arranged,” the statement said. In October 2013, Unit-1 of the KKNPP was connected to the southern power grid.

In August 2016, unit-2 of the Kudankulam nuclear power plant was connected to the power grid. Currently, units-3 and 4 are under construction. The contracts for construction of unit-5 and 6 have been signed and the preparatory works are in progress.

Both Kudankulam units shut, 1,000 MW shortfall for Tamil Nadu

CHENNAI: Both units at Kudankulam Nuclear Power Project have come to a stand-still, resulting in a shortfall of 1,000MW for Tamil Nadu Generation and Distribution Corporation (Tangedco).
Unit 2, which had stopped power generation in December last, is yet to resume.
The first unit was stopped on Tuesday night owing to a technical snag. About 50% of power generated at Kudankulam power plant is supplied to Tamil Nadu.
“We were getting around 300MW from Unit 1 till a few days ago. As there is no communication from the plant as to what is the real issue and when generation will resume, we are not taking supply from Kudankulam into consideration for our planning,” said a senior Tangedco official.
As per Nuclear Power Corporation of India Limited (NPCIL) website, Unit 2 generated 3,641 million units of power in 2019-20 and Unit 1 generated 5,586 million units. Efforts to seek response from NPCIL officials were in vain.
Compared to other nuclear power units in the country, the Kudankulam units have been performing below par. For example, four units in Kaiga have a capacity factor of not less than 90%. Some have crossed 100%. In comparison, the capacity factor of Kudankulam Unit 1 is 80% and Unit 2 is only 50%. Since February 1, power demand has been surging in the state. The peak demand is around 14,500MW, which is a new high for February. “All our thermal units are working at full capacity. Beyond that, we are purchasing power from central thermal and nuclear units as well as from the market to meet the peak demand,” said the official. At times, wind power is available, but it is restricted to evening time.
“Till wind power season begins, we have to depend on thermal and nuclear units for power supply. That explains our dependence on Kudankulam,” said the official.

I am not sure why we are buying 4 more units from Russia. This junk plant is shut for more days than its operating days
its not junk. It has saved TN in the past, when entire unit was given to TN for few months.

365 days in a year. few days shut of here and there, wont be a big loss.

I worked in production plant, where some periodic maintenance happens. it might be a some reason for the plants to be shutdown for some reason for few days.

Even if it is run for 50% of the days, still the cost of power it is generated in that 50% days is very less compared to thermal plant same amount of power in that 50% time.

Also remember, In the past, TN suffered with thermal plants also due to "sharing" cost of coal imports, allocation etc.

could you give us the actual data on how many days, kudankulam was shut down last year or previous years? or how much units it has produced?

No other reactor in the world shut long like this koodankulam.crores wasted.dont know what's the issue.they planned to construct more reactors in this plant.they will complete it in 2030 and shut down 4 reactors every 6 months.by this time world will switch to solar power..Every year 500mw power requirement needed.solar is the only solution

Solar or wind can never be the complete replacement. Thermal, gas and nuclear are what is essentially called base load powerplants, which can give continuous supply of power without any interruption because of external factors. Like no wind, or no sun light or no water in case of hydroelectric. These can be shut down when other non base load ones operate at optimum capacity, like TN shutting down thermal power generation when wind power is very high at times.
So, unless battery technologies reach a stage where we can store and distribute power CHEAPLY to tens of millions of people for weeks or potentially months, nuclear is the only way to go. Since, the alternate coal and gas are very very bad to environment as you may know.

From 2017 onwards KKNPP capacity factor is more than 65%,this plant operating pattern is 300 full power days for one fuel loading ,then refuelling is needed is needed for 40 days,occasionally in between some times trips (this happens to all power plants like grid disturbance etc),but nuclear plant has extra care ,if plant trips get permission from AERB (from MUMBAI) for restarting.
