Tata to commission second unit of Mundra UMPP by August; will increase the coal imports…

image

Power India found that Tata Power Limited is expecting to commission  second unit (800 MW) of  its 4000 MW Ultra Mega Power Project (UMPP) at Mundra Port, Gujarat by end August 2012.

 

Tata Power is developing a 4000 MW UMPP at Mundra in the state of Gujarat which comprises of 5 Coal Fired Super Critical units of 800 MW. Tata Power bagged the Mundra project in 2007 on the basis of the lowest tariff bid of Rs 2.26 a unit, but a change in the coal pricing policy in Indonesia has upset the cost structure of the project.

First unit of this project has been commissioned in March 2012 and with that the said UMPP was country’s first UMPP to start generation.

 

Mr. Anil Sardana, Managing Director, Tata Power has told the reporters during the CII conference that, the company is expecting to commission the second unit by August 2012.

 

Further, Mr. Sardana said that work is progressing on vary fast track basis for the remaining three units of Mundra UMPP and that it was committed to commission them with a time gap of four to five months between the units.

 

The Project when commissioned will supply power to various states such as Gujarat, Maharashtra, Rajasthan, Haryana & Punjab. The Project will utilise the imported coal with the super critical boiler technology which is environment friendly as per the company officials.

 

However, currently the project is using 50% of low grade coal and 50% of normal grade coal.

In the current fiscal, Tata Power expects to import 15 million tonnes coal, which would be utilised for Mundra and Trombay projects, Sardana said. The company imported about 5.5 million tonnes coal in 2011-12.

Gamesa to set up wind turbine manufacturing plants in Chennai & Baroda…

Gamesa Wind Turbine

Power India found that Gamesa Corp. Tecnologica SA Spanish Wind Turbine Manufacturer which is at no 8 in the world and no 2 in Europe has announced that they are going to open a third factory in India which will be in Chennai.

 

As per the news article on Wall Street Journal, Gamesa is  planning to spend around Rs. 2.0 Billion; so far they have invested around Rs. 5.50 Billion for factories in India.

 

The proposed manufacturing plant will be used to produce the G9X-2.0 MW series of turbines.

 

Gamesa is also building  two facilities in the western city of Vadodara to manufacture wind-turbine parts.

 

As said by Gamesa:

India is a key emerging market for Gamesa, Europe's second-largest wind-turbine manufacturer by market value after Vestas Wind Systems A/S (VWDRY), as it is facing a slump in demand in its traditional markets of the U.S. and Western Europe which are hurt by an economic slowdown.

Gamesa sold 8% of its turbines in Spain last year, compared with 39% three years earlier. Its largest markets now are China and India.

 

Gamesa got 20 percent of its sales in India last year and expects that share to climb, targeting 711 megawatts in sales by the end of December, according to Kymal (Chairman, India unit)

 

Recently, Games has got a 150 MW Contract from Myrah Energy Ltd which is the part of long term strategic relationship of 2000 MW by 2016.

 

As captured by Bloomberg; competition among turbine makers in China has grown amid a supply glut, putting pressure on prices as manufacturers seek to contain costs. India has now become the wind industry’s largest growth market by volume after China tightened project approvals and Europe and the U.S. reined in financing amid burgeoning debt, the Global Wind Energy Council said last month.

 

India is focusing on harnessing more energy from sources such as wind as it aims to reduce its dependence on fossil fuel.

 

The country's installed renewable-energy capacity is about 24 GW and the government aims to increase it to 50 GW by 2020.

 

India is the world's fifth-largest wind energy market. Wind-energy accounts for nearly three-fourths of the country's total renewable-energy capacity.

Patent application filed by Chennai based Raghu Nathan for reactive power management in wind turbine applications…

image

Power India found that Chennai based Valagam Rajagopal Raghunathan has applied to the Controller General of Patents, Designs & Trade Marks for his invention regarding reactive power management for wind turbine applications.  

 

The application was filed to Controller General of Patents, Designs & Trade Marks on June 21, 2010 with the application number 1716/CHE/2010. The international classification number is F03D.

 

This invention relates to electrical power generation and in particular to reactive power management in an asynchronous generator wind turbine without the usage of capacitor banks for the power factor and excitation maintenance.

 

Further, the invention concerns with a system for generating the required reactive power from a separate built in power source to maintain self excitation and to sustain the operation without usage of any physical capacitor banks switching with the generator lines within the predefined operation conditions (changes in wind speed, load).

 

The system generates the required reactive power from a separate built in power source to maintain the power factor to the optimum level for higher efficiency without any separate capacitor banks switching in the generator power line.

 

A control system which monitors whose input signals are generator's rotor speed, load, excitation voltage and provide necessary relative power to the SEIG is taken from a DC source through controlled IGBT drivers.

 

The pulse width modulation (PWM) of the IGBT is controlled by varying the modulation index by the control system, and the feed back for the reactive power required based on the charge accumulated on the DC side of the IGBT inverter.

 

The proposed design system monitors the wind speed, local load requirement, grid availability and accordingly manages the power distribution for optimum usage of the power produced by the wind turbine,

 

This system is used to work as a standalone wind turbine without grid power to provide electrical power for devices like pump, heaters, etc or with the grid power connected where the generated power is exported fully/partially after usage of the local loads like pump, heater, etc. or with grid power connected, when there is no sufficient wind energy is available to supply power from grid to the local loads like pump, heater, etc.

GMR moved to Supreme Court for non-payment of Rs. 600 Crs by Tamil Nadu Electricity Board…

image

Power India found that GMR Power Corporation Private Ltd has filed a case against Tamil Nadu Electricity Board (TNEB) for non-payment of tariff invoices amounting to around Rs. 600 Crs from the 200 MW Diesel Based Power Project at Basin Bridge.

 

GMR had entered into a power purchase agreement (PPA) with TNEB in September 1996 for setting up a 200 MW Diesel Power Plant at Basin Bridge of Chennai.

 

The infrastructure company had also entered into a fuel supply agreement with HPCL in December 1996 for purchase of low sulphur heavy stock fuel for its diesel engine based power plant and onward sale of power to the electricity board.

 

GMR had a dispute with the state electricity board with respect to PPA, land lease rentals among others.

 

GMR had earlier filed a petition against non payment of invoices by TNEB to Tamil Nadu Electricity Regulatory Commission in the year 2008.

  • Tamil Nadu Electricity Regulatory Commission by its order dated April 16, 2010 had allowed the claims of GME and directed TNEB to pay approximately Rs 480 crore with interest in six equal monthly instalments to the former.

 

However, thereafter TNEB has approached the Appellate Tribunal for Electricity.

  • The Aptel wide its order dated February 28, 2012  had ruled in favour of GPC.
  • Aptel ruled that reimbursements received by GMR from Hindustan Petroleum Corporation Ltd (HPCL) by way of fuel credits should be paid or set-off against dues payable by the Tamil Nadu Electricity Board (TNEB).

 

Recently, GMR has challenged the above petition into the Supreme Court.

  • A bench headed by Chief Justice S H Kapadia has sought reply from HPCL as to whether such credit has been given by it gratuitously to GMR as claimed by the latter.
  • However, it asked the parties to maintain “status-quo as far as inter-se adjustment is concerned.”
