The TG Hall

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)

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

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. S-I coal mill motors are 240 KW and PA fans are 400 KW. The first phase of the project, a 800 MW unit, was inaugurated by Prime Minister Narendra Modi on 3 October 2023.


STAGE 2 (3×500 MW)

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

(BHEL).


Stage 3 (1×500 MW)

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. Many Power plant engineers train in this unit to upgrade themselves to this new mode of operation.


Overhauls

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
