THDC Recruitment Through GATE 2027: THDC India Limited has opened one of the widest-discipline PSU recruitment drives of the GATE 2027 cycle. Through Advertisement No. 03/2026, THDC is hiring Engineer Trainees (ET) across eight engineering and science disciplines, from the usual Civil, Electrical and Mechanical streams to less common ones like Geology, Chemistry and Environmental Science, all based on GATE-2027 scores.
This matters for a wider pool of candidates than most GATE-PSU drives. If you are from Mining, Instrumentation, Chemistry, Environmental Science or Geology, opportunities like this are rare, since most PSUs restrict hiring to the four or five core engineering branches.
As with other PSU-GATE drives this cycle, the message is consistent: only GATE 2027 scores will be accepted, and the detailed application window will be announced separately. Your first step is to register for GATE 2027 before the deadline.
In this guide, you will find:
- what THDC India Limited is and its PSU standing
- eligible disciplines and their GATE paper codes
- the selection process as stated in the official notice
- important GATE 2027 dates
- how to apply and prepare
All details below are taken directly from THDC’s official Advertisement No. 03/2026, except where marked otherwise as reference from earlier cycles.

What Is THDC India Limited?
THDC India Limited (formerly Tehri Hydro Development Corporation Limited) is a leading power sector and profit-making Schedule “A” Mini Ratna PSU functioning under the administrative control of the Ministry of Power, Government of India. Its equity is shared between NTPC Limited and the Government of Uttar Pradesh, making it a subsidiary within the NTPC group of companies.
THDC is best known for hydroelectric power generation, and its company motto, “Generating Power, Transmitting Prosperity,” reflects its role in India’s power infrastructure.
Eligible Disciplines and GATE 2027 Papers
THDC’s Engineer Trainee recruitment spans eight disciplines, each with its corresponding GATE 2027 paper code, as specified in the official notice.
| THDC Discipline | GATE 2027 Paper Code |
|---|---|
| Civil Engineering | CE |
| Electrical Engineering | EE |
| Mechanical Engineering | ME |
| Mining Engineering | MN |
| Chemistry | CY |
| Environmental Science | ES |
| Geology | GG |
| Instrumentation Engineering | IN |
Why this list stands out: Most GATE-based PSU drives cover only four or five core engineering branches. THDC’s inclusion of Chemistry, Environmental Science and Geology alongside Mining reflects the diverse technical needs of a large hydroelectric and power infrastructure company, covering everything from dam geology to environmental compliance.
Make sure your GATE paper matches your discipline exactly, since eligibility is tied to the paper code specified above.

| General candidates | 30 years |
| OBC (Non-Creamy Layer) | 33 years |
| SC/ST candidates | 35 years |
| PwD (General) candidates | 40 years |
The earlier cycle also required a minimum of 65% marks in the relevant engineering discipline. Wait for THDC’s 2027 detailed advertisement before finalising your eligibility, since criteria can change between cycles.

GATE 2027 Preparation Tips for THDC Aspirants
- Confirm your paper-to-discipline match first. With eight disciplines on offer, double-check that your degree qualifies you for the GATE paper you plan to attempt.
- Focus on core, high-weightage topics. For CE: structural and geotechnical engineering, relevant to dam and hydro infrastructure. For EE and ME: power systems and thermal/hydro power engineering. For MN and GG: mining methods and engineering geology. For IN: measurement and control systems.
- CY and ES candidates should note that GATE’s Chemistry and Environmental Science papers fall under specific paper codes; verify the exact code on gate2027.iitm.ac.in before registering.
- Check the revised GATE 2027 syllabus for your specific paper, since several subjects have been updated this cycle.
- Solve previous years’ GATE papers under timed conditions, since negative marking penalises guesswork and accuracy matters more than attempting every question.
