If you have studied B.Tech in Computer Science Engineering at the graduate level, then you are eligible to apply for admission at the National Power Training Institute (NPTI) in Nagpur. While NPTI mainly focuses on training in the power and energy sector, some courses are related to areas like IT, automation, and management. These areas may have relevance to Computer Science students, especially those interested in fields like data management for power plants and automation and control systems. For example, there is a course at NPTI that involves smart grid technology or IT solutions for the power sector. In this field as a Computer Science student, you may find it useful and eligible to enroll. However, check the specific eligibility criteria for each course in NPTI's website, as some courses may require a background in Electrical or Mechanical Engineering, while others may be open to Computer Science graduates.
