Northeast Utilities High School Internship

Hi everybody,

I am currently a freshman at a target school looking for a summer finance internship of some sort. In the summer following my junior year of high school, I interned for eight weeks at Northeast Utilities as an engineering/finance intern, basically assisting young engineers and project managers. It was an unpaid internship, but I was there from 9-5 Monday through Friday. Even though this was almost two years ago, Northeast Utilities is a Fortune 500 company, and my only other experience working has been as a lifeguard. So, my question is, is it a good idea to discuss and highlight this on my resume and/or application for various summer finance internships? Would it be a good idea to include it again for later internships (sophomore or junior summer internships) or would this Northeast Utilities internship be irrelevant for that time.

Thanks in advance for all the help
