downeve,
It will help that your B.S. is in a higher difficult field of study but yeah, your GPA may raise some concerns about your motivation to do well academically. Were your grades better during the later years? Also, what's your GPA in the B.A. Economics course as good grades over here may help you present your case in a much better way. There are many way to address a low GPA and you can read about them
over here Your experience is a tad lower than the average workex for most of the one year program (and HEC's 16 month will probably fall under the same set) however a lot will depend on what you make out of it. It will be critical for you to showcase that you are a rock star at work with lots of leadership experiences. Also, your extracurricular seems to be the weakest part of your profile as not much is mentioned on that side. As far as your goals are concerned, they seem logical to what you are currently doing and the specific Energy offering from HEC's program.
Every year, many applicants with far better "numbers" than you do not get in and those with worse do get the offer letter. Overall, your chances of success will depend on how well you can fill the gaps that are mentioned above and execute your application because at the end of the day, admissions committee members will look at those pieces of paper to make the judgments.
