ExploreAbout this exam
The TSGENCO Assistant Engineer (AE) recruitment exam is the screening gate used by the Telangana Power Generation Corporation to shortlist graduate engineers for assistant engineer posts in its generating stations and corporate offices. It is aimed at candidates with a B.E./B.Tech (or equivalent) in Electrical, Mechanical, or Civil Engineering who want a state-sector generation utility role rather than a transmission or distribution one. Because TSGENCO runs thermal, hydel and renewable plants, the paper is deliberately broad: electrical candidates face power systems, machines, power electronics, measurements and control alongside shared thermal, fluid and design material; mechanical and civil candidates get the mirror image. General studies, analytical ability and Telangana-focused awareness carry a smaller but decisive share. Preparation works best in three passes: rebuild core engineering fundamentals from standard textbooks, drill numerical problem types under time pressure, and finish with sectional mock tests plus a current-affairs and Telangana review. The official notification and TSGENCO website remain the only authority on eligibility, vacancies, syllabus weightage and selection stages; treat coaching summaries as secondary.

What you'll study
About TSGENCO AE preparation
What is the TSGENCO AE exam format?
It is a computer-based or OMR multiple-choice test in the language the notification specifies, with separate sections for the relevant engineering branch, shared mechanical topics, general studies and analytical ability. The exact section structure, marks distribution and negative-marking rule are fixed afresh in each notification, so read the current official notification rather than older patterns.
How long is the exam and how many questions are there?
Those figures change between recruitment cycles and are published only in the official notification issued by TSGENCO. Do not rely on numbers quoted in old test series or forum posts. Check the TSGENCO website and the current notification PDF for the authoritative question count, duration and marking scheme before you plan your exam-day pacing.
How difficult is the paper compared with GATE or a PSU exam?
Conceptual depth is closer to a state PSU paper than to GATE: fewer multi-step derivations, more direct application and recall across a wide syllabus. The real difficulty is breadth, because electrical candidates must also handle thermal engineering and general studies. Candidates who prepare only their own branch usually lose marks in the shared sections.
Is there negative marking, and should I guess?
Negative marking has varied across TSGENCO cycles, so confirm the rule for your notification. If one-third or similar negative marking applies, answer only where you can eliminate at least two options; blind guessing across many questions costs more than it gains. If no penalty is stated, attempt every question.
Can I retake the exam if I am not selected?
Yes, subject to age limits and eligibility in each notification. There is no lifetime attempt cap for this recruitment, but vacancies, branch-wise eligibility and age relaxation are redefined every cycle. Candidates who miss the cut-off typically reappear in the next notification after strengthening their weakest section.
What study order do successful candidates usually follow?
Start with branch core subjects because they carry the largest weight, then add the shared thermal and fluid topics, and keep general studies and Telangana awareness as a running daily habit rather than a last-week cram. Finish with full-length timed mocks and a review of every wrong answer, since error analysis is where most score gains come from.
Which subjects cause the most failures?
Three patterns recur: neglecting the non-branch sections entirely, memorising formulas without practising numericals, and poor time allocation in the analytical section. Thermal engineering topics such as Rankine cycle efficiency, boiler performance and turbine staging trip up electrical candidates, while power systems and machines numericals catch mechanical candidates.
Does the exam test Telangana-specific current affairs?
Yes, a portion of general awareness is state-focused, covering Telangana's power sector, government schemes, geography and recent developments. Read the state's major newspapers and official utility announcements for the months before the exam. National current affairs still matter, so balance both rather than studying only state news.
How much time should I budget for preparation?
Most working engineers need roughly four to six months of consistent study at two to three hours a day to cover branch core, shared mechanical topics and general studies with mock practice. Candidates fresh from college can compress this, but should still reserve the final month exclusively for revision and timed tests rather than new topics.
Where do I confirm eligibility, fees and important dates?
Only the official TSGENCO notification and website. This guide deliberately does not quote fees, dates or passing scores because they change each cycle. Download the notification PDF, verify your branch and age eligibility, and track corrigendum updates, since corrections to eligibility or syllabus are sometimes issued after the first publication.
