Thermal Powertech Corporation India Ltd (TPCIL) has synchronised the second 660 MW unit of its 1,320 MW coal-fired thermal power plant with the grid on 11 August.
The power plant is situated at Krishnapatnam in Nellore district of Andhra Pradesh, whose first unit of 660 MW was synchronised in 2014 and started commercial operations from February 2015.
The commercial operation of second unit is expected to commence by September 2015 with which it will function in full capacity of 1,320 MW.
The thermal power plant is developed and operated by TPCIL which was incorporated in 2008 as a joint venture company between Hyderabad-based Gayatri Energy Ventures Private Limited and Singapore-based SembCorp Utilities.
The Singapore-based Sembcorp Industries has gross power capacity of over 8,200 MW and has over 3,340 MW of capacity in India of which 2,640 MW is of thermal energy and 700 MW in from renewable energy.
Fuel Source: The JV has fuel supply agreements with Mahanadi Coal Fields and Indonesia-based PT Bayan Resources for the supply of coal for its super-critical coal-fired power plant.
On 7 August Bharat Heavy Electricals Limited (BHEL) commissioned a 500 MW thermal unit of NTPC’s Vindhyachal Super Thermal Power Station (STPS) in Vindhyanagar, Singrauli district of Madhya Pradesh.
BHEL has successfully commissioned the seventh unit of 500 MW at Vindhyachal power station summing up to 3,500 MW the highest done by BHEL in power projects.
For this project, BHEL had contributed in engineering, manufacture, design, supply, erection and commissioning of steam turbines. It also had important role in installing generators and boilers, along with associated auxiliaries and electricals, controls & instrumentation (C&I) and electrostatic precipitators (ESPs).
BHEL particularly makes sets of 500 MW rating class and has commissioned so far 76 sets in the country. The sets supplied by BHEL have better operating Heat rate that consumes less coal while producing per unit of power.
It should be noted that BHEL has established higher rated unit and thermal sets with a high degree of indigenization. In current financial year (2015-16) it has commissioned power plants with a cumulative capacity of 2,480 MW.
About Super Thermal Power Stations (STPS)
Super Thermal Power Stations (STPS) are a series of ambitious coal based power projects planned by the Government of India in 1990. The capacity of such thermal plant is 1000 MW and above.
There are over 65 STPS in India and Mundra Thermal Power Station of Adani Power in Kutch district of Gujarat is the largest among all.
Note: India stands fifth in the world in production of thermal power. It produces over 1108 TW and its consumption demand is expected rise to 1905 TW by 2022.
