'''Raichur Thermal Power Station''' ('''RTPS''') is a [[coal]]-fired [[electric power station]] located at Yadlapur D(Shaktinagar) in the [[Raichur district]] of the state of [[Karnataka]], [[India]]. It is operated by the [[Karnataka Power Corporation Limited]] (KPCL) and was the first thermal power plant to be set up in the state.<ref name="Projects">{{cite web|url=http://www.karnatakapower.com/projects.asp|title=Projects of KPCL|accessdate=2007-10-27|url-status=dead|archiveurl=https://web.archive.org/web/20110712141736/http://www.karnatakapower.com/projects.asp|archivedate=2011-07-12}}</ref><ref name="frst">{{cite news|url=http://www.hindu.com/2007/03/26/stories/2007032611000500.htm|archive-url=https://web.archive.org/web/20121025203026/http://www.hindu.com/2007/03/26/stories/2007032611000500.htm|url-status=dead|archive-date=2012-10-25|title= More locations identified to set up power plants|accessdate=2007-11-01|location=Chennai, India|work=[[The Hindu]]|date=2007-03-26}}</ref> The power station was commissioned during various periods from 1985 and it accounts for about 70% of the total electricity generated in [[Karnataka]].<ref name="forty">{{cite news|url=https://www.thehindu.com/todays-paper/tp-national/tp-karnataka/All-units-of-RTPS-going-full-steam/article14702954.ece|date=7 January 2007|newspaper=The Hindu|title= All units of RTPS going full steam|accessdate=15 December 2019|location=Chennai, India}}</ref>

==Establishment==
The project to construct the thermal power station was finalized in 1978 after an [[Memorandum of understanding|MOU]] was signed between KPCL and the Karnataka State Electricity Board.<ref name="tce"/> TCE Consulting Engineers Ltd., a [[Tata Group]] company was appointed as the consultants for the project. The project involved two stages: Stage I, in which Units 1 and 2 were expected to be installed and Stage II, Units 3 and 4. each unit was expected to have an installed capacity of 210 MW. An area of 300 hectares was allocated for the units. Unit I of the plant was completed in March 1985, with Unit II following in March 1986.<ref name="tce">{{cite web|url=http://www.tce.co.in/power/thermal/raichur.pdf|work=Online Webpage of TCE Consulting Engineers Ltd., A TATA Enterprise|title=Karnataka Power Corporation Limited, 2 x 210 MW Raichur Thermal Power Plant : Stages – I & II|accessdate=2007-11-01}}</ref>

The construction of Unit III was started in 1986 and completed in March 1991 and the Unit IV was started in 1989 and completed in September 1994, thereby completing the Stage II. The total cost of Stage I of the project was [[Indian rupee|Rs.]] 4,030,000,000 and of the Stage II was [[Indian rupee|Rs.]] 9,830,000,000. The [[Electrical generator|generators]] were supplied by [[Bharat Heavy Electricals Limited]] and the [[turbine]]s by Kraftwerk Union AG (KWU) and [[Mitsubishi]]. In 1996, a further expansion of the plant was carried out, with an investment of [[Indian rupee|Rs.]] 15,450,000,000.

Units 5 and 6 (each of 210 MW) were installed within three years.<ref name="rpow">{{cite web|url=http://www.karnatakapower.com/raichur.asp|work=Online webpage of KPCL|title=Raichur Thermal Power Station|accessdate=2007-11-01}}</ref> Unit 7 (210 MW) which was completed within a record time of 25 months, was installed at the end of the year 2002<ref name="rpow"/> The total installed capacity of the power plant is 1,470 MW (7 x 210 MW). {{As of|2007}}, Unit 8, with an installed capacity of 250 MW, is being constructed and is expected to be operational by September 2009.<ref name="unit8">{{cite web|url=http://www.karnatakapower.com/rtps.htm|work=Online webpage of KPCL|title=Raichur Thermal Power Station-Unit 8|accessdate=2007-11-01|url-status=dead|archiveurl=https://web.archive.org/web/20071201052851/http://www.karnatakapower.com/rtps.htm|archivedate=2007-12-01}}</ref>

Stage I (units 1 and 2) costing Rs. 403 crores in 1986.

Stage II (units 3 and 4) costing Rs. 983 crores in 1994.

Stage III (units 5 and 6) costing Rs. 1545 crores in 1999.

Stage IV (unit 7) costing Rs. 613 crores in 2002.

Stage IV (unit 8) costing Rs. 945 crores in 2010

==Raw materials==
RTPS uses coal for generation of [[electricity]]. Its daily requirement of coal is about 20,000 metric tons, when running at full capacity, which is delivered from Western Coalfields Ltd. and Mahanadi Coalfields Ltd.
The coal supplied is sampled using a computerized system and sent to the laboratory for testing. This ensures that the proper grade of coal is used.

The plant has also started to use washed coal, due to its lower ash content.<ref name="wac">{{cite news|url=http://www.hindu.com/2004/01/12/stories/2004011200980300.htm|archive-url=https://web.archive.org/web/20040218043756/http://www.hindu.com/2004/01/12/stories/2004011200980300.htm|url-status=dead|archive-date=2004-02-18|title= Coal sampling computerised|accessdate=2007-11-01|location=Chennai, India|work=[[The Hindu]]|date=2004-01-12}}</ref>

The plant's cooling water is pumped from the [[Krishna river]] nearby.

==Electricity production==
The coal is pulverized and fed into furnaces that convert water into steam. This steam runs the turbines to generate electricity. Units 1 to 7, each can produce 5.04 MU of energy per day and Unit 8 can produce 6 MU per day, hence the plant can produce 41.28 MU of energy per day when it is functioning at full capacity.<ref name="cashu">{{cite web|url=http://www.esgindia.org/projects/SACODI/Guidelines_part_I.pdf|title=Guidelines for Hazardous waste, Part I, Recommendations for environmental politics and administration, Introduction of collection and disposal systems under particular consideration of framework conditions in India and Vietnam, Ver 1.0, Oct 2006|work=Sacodi Project|accessdate=2007-11-01}}</ref>

==Issues==
RTPS generates about 1.5 million tonnes of [[fly ash]] annually which causes environmental problems. 20% of the ash produced is wet [[bottom ash]] which is let into the ash bund.<ref name="cashu"/> Though considered safer than fly-ash, bottom ash has also been found to contain [[heavy metals]] which can be dangerous to public health. The fly-ash which gets generated during the burning of coal disperses into the air and hence pollutes the atmosphere. This gets deposited on the surrounding land, thereby making the land infertile. The fly-ash may also cause breathing problems for humans. RTPS has taken steps to ensure that fly-ash gets precipitated out of the air by using [[electrostatic]] elements in the furnaces, but about 2% of fly-ash gets into the atmosphere.<ref name="cashu"/> The fly-ash is disposed of by converting it into a wet slurry and dumping it into vacant tracts of land (which become what are known as ash-ponds).<ref name="barr">{{cite web|url=http://www.thehindubusinessline.com/life/2006/08/04/stories/2006080400220400.htm|work=Online Edition of The Hindu Business Line, dated 2006-08-04|title= Cashing in on fly ash|author= Bharathi Ghanashyam|accessdate=2007-11-01}}</ref> This is not environment friendly and hence RTPS has come up with ways to make better use of fly-ash. It has entered into a collaboration with the Indo-Norwegian Environment Programme (INEP) and has set up a technology demonstration center called CASHUTEC (Center for Ash Utilization and Environment Conservation) near its plant.<ref name="barr"/> CASHUTEC demonstrates different uses for fly ash; mainly its use in the construction sector for making bricks, blocks and mosaic tiles.<ref name="barr"/>
