'''NTPC Ramagundam''', a part of [[National Thermal Power Corporation]],<ref name="ntcp"/> is a 2,600 [[megawatt]] (MW) [[thermal power station|Power station]] situated at [[Ramagundam]] in [[Peddapalli district]] in [[Telangana]], [[India]]. It is the current largest power station in South India. It is the first [[ISO 14001]] certified "Super Thermal Power Station" in India.<ref>{{Cite web |url=http://karimnagar.nic.in/ntpc.html |title=Archived copy |access-date=11 December 2009 |archive-url=https://web.archive.org/web/20100523015645/http://karimnagar.nic.in/ntpc.html |archive-date=23 May 2010 |url-status=dead }}</ref>

==The TG Hall==
{{Unreferenced-section|date=March 2021}}
[[File:TG HALL 1.jpg|right|thumb|Turbo-Generator Hall, UNIT#7, NTPC Ltd., Ramagundam]]
The TG Hall or the Turbo-Generator hall or the Turbine-Generator Hall is the hall or space where the turbine-generator sets are present.

NTPC Ltd., Ramagundam has two TG Halls one for STAGE-I and the other common for STAGE-II and STAGE-III. These TG halls are equipped with heavy overhead cranes that assist in transportation of material within the TG hall. These cranes find their use greatly during overhauls.

==Unit-wise power generation==
The whole plant is divided into 3 stages, each stage being planned at one time.

===STAGE 1 (3×200 MW)===
{{Unreferenced-section|date=March 2021}}
This stage consists of three units (Unit-1, Unit-2, Unit-3) each with a generation capacity of 200 MW. The turbines for these three units were manufactured by The [[Ansaldo Energia]] Ltd.
The construction began in the late 1970s and these units have performed well over a long period, setting many records regarding maintenance and generation over the other two stages. BUT stage (1, 2, 3) cwp motors are manufactured by BHEL and all motors are manufactured by Ansaldo.{{Clarify|date=February 2021}} S-I coal mill motors are 240 KW and PA fans are 400 KW.

===STAGE 2 (3×500 MW)===
{{Unreferenced-section|date=March 2021}}
This stage also consists of three units (Unit-4, Unit-5, Unit-6) each with a generation capacity of 500MW. The turbines for these three units were manufactured by [[Bharat Heavy Electricals Limited]] (BHEL).
[[File:STAGE III.jpg|left|thumb|Outside view of STAGE-III (Unit#7)]]

===Stage 3 (1×500 MW)===
{{Unreferenced-section|date=March 2021}}
This stage comprises only one unit (Unit-7). It is a first of its kind in South India, being a computer operated unit. A wide disparity may be seen between the control rooms of the other two stages and this computerised unit. To this day,{{When|date=February 2021}} many Power plant engineers train in this unit to upgrade themselves to this new mode of operation.

==Overhauls==
{{Unreferenced-section|date=March 2021}}
Once every two years, these units are stopped and overhauled, one unit at a time. The overhauls are usually taken up from June to September as the [[monsoons]] increase [[hydropower]] generation which substitutes for the [[power generation]] lost due to the overhaul of the unit. The same practice is followed throughout the country. The overhauls usually take 15 to 20 days per unit provided there is no major repair involved. Major repairs include turbine casing, turbine rotor damage and other damages that require transporting the equipment to another location (usually the manufacturer). The overhauls are the dissipators of the annual PLF of any [[power plant]].{{Jargon inline|date=February 2021}}

==Generation distribution==
{{Unreferenced-section|date=March 2021}}
===States===
As NTPC Ltd. is a [[Public Sector Undertaking]] (PSU), the generation is almost uniformly distributed to 5–6 states, all of which share about 20–25% of the output. These States include:
*[[Andhra Pradesh]]
*[[Telangana]]
*[[Tamil Nadu]]
*[[Kerala]]
*[[Karnataka]]
*[[Maharashtra]]

=== Electrical substation ===
{{main|Electrical substation}}
{{Unreferenced-section|date=March 2021}}
The substation is the place where the station last interacts with the power it produces. The switchyard links the power generated to the southern [[power grid]]. The major transmission points are:
*[[Nagarjunasagar]]
*[[Chandrapur]]
*[[Hyderabad, India|Hyderabad]]
*[[Khammam]]

==Inputs==
{{Unreferenced-section|date=March 2021}}
===Water===
The power station is provided water periodically by the [[Sriram Sagar Project]] (SRSP). This water is stored in the balance reservoir. The water level in the balance reservoir is monitored daily.

===Coal===
[[File:BOBRN class Hopper cars Freight rakes at Samalkot Junction 01.jpg|thumb|BOBRN class [[hopper car]]s freight [[Rake (train)|rakes]] used by [[Indian Railways]]]]
NTPC [[Ramagundam]] is a [[Coal-fired power station]]. This coal is available at a large scale from the [[Singareni]] Coal mining company nearby and is transported using the MGR (Merry-go-round) system, wherein a train travels on one [[Rail line|rail route]], delivers coal and returns on another route. The [[Hopper car|hopper wagons]] arriving by this route are taken for coal collection where a [[Mechanism (engineering)|mechanism]] provided underneath the wagons opens on application of [[air]] [[pressure]] and drops the coal it is carrying. A separate department (MGR Dept.) handles this process.

Coal also arrives by the [[Indian Railways]]. The [[open wagon]]s are routed via [[Ramagundam railway station]] to the separate plant line and these wagons arrive at the [[wagon tippler]]. The wagons arriving in this manner must be tilted at the wagon tippler to unload the coal as they do not have the drop mechanism underneath.

===Other petroleum products required===
The station also requires various oils for the following purposes:
*[[Turbine]] oil (SP-46) for turbine [[lubrication]]
*[[Heavy fuel oil]] (HFO) for [[boiler]] start-up
*[[Diesel fuel|Diesel]] for DG sets (Power backup)
*Other oils for various hydraulic controls and circuits

These are periodically purchased as per requirement from the Indian oil corporation [[IOCL]] establishment nearby.
