The installation time for a gas turbine power plant is
Comparatively less than thermal power plant
Comparatively more than thermal power plant
Equal to thermal power plant
Very much longer than thermal power plant
Comparatively less than thermal power plant
Quick Summary: Gas turbine power plants require significantly less installation time compared to thermal (coal-fired) power plants because they consist of compact, modular components. Thermal power plants require large-scale civil works, massive steam generators, and complex boiler setups that lead to much longer construction and commissioning periods.

Wnet=Wturbine−Wcompressor — Net work output of a gas turbine
ηth=1−(rp)γγ−11 — Thermal efficiency based on pressure ratio
The principle relies on the Brayton Cycle where air is compressed, heated, and expanded through a turbine. Because there is no need for large steam boilers, cooling towers, or extensive coal handling units, the site preparation and installation are modular and rapid.
Gas turbine plants are ideal for peak load duty.
Thermal plants are typically used for base load duty due to their large size and slow startup.
Civil engineering requirements for gas turbines are minimal compared to the elaborate foundations required for heavy thermal power equipment.
Lower capital investment
Quick start-up and shutdown time
Low maintenance cost
Small floor area required
Lower overall thermal efficiency
High running cost due to expensive fuel (natural gas/distillate oil)
Short life span of turbine blades due to high operating temperatures
Peak load power generation
Standby power units
Industrial captive power plants
| Feature | Gas Turbine | Thermal Plant |
|---|---|---|
Installation Time | Very Short (Months) | Very Long (Years) |
Thermal power plants involve complex logistics including coal transport networks and water supply systems.
Option B, C, and D are incorrect because they ignore the compact and modular nature of gas turbine systems compared to the massive scale of steam-based thermal plants.
A is correct — The modular design of gas turbine plants allows for much faster installation and commissioning than large-scale coal-fired thermal power plants.
Always relate plant installation time to the complexity of the heat source; coal-fired thermal plants are complex because they require extensive boilers and steam-cycle infrastructure.
