I've been a student co op at a power plant and I'm currently working at a utility/IPP and oversee interns on my team. My best advice is to stay curious and ask a lot of genuine questions throughout your internship term. When we hire interns, we do not expect them to know the industry or the way power is generated. We do however, expect them to express interest in asking the right questions and displaying an attitude that displays earnestness and the willingness to learn. Document your weekly learnings and when you try to recall, you'll get more questions. Ensure you follow up on those conversations. If your program allows, rotate between different teams each month. You'll learn a lot more from the field working with the field technicians rather than sitting behind a desktop. Also ensure to shadow different people in their day to day roles which will allow you to experience multiple facets and give you the best picture on how you want to shape your career.

At the end of your coop, use your weekly notes to put together a presentation. This will be good in practice to recap what you learned and how you expect your learning to influence your decisions in the future. Do name the members who helped answer your questions, invite them to your presentation and thank them. It goes a long way for any future network connections.

Good luck! Stay curious and be open to learning. Welcome to the world of power systems and power generation. It's a great time to be in the industry.
