Student Activities

Scholarship Activity – Power Company Sponsored Scholarships

The department awarded approximately $60Kin scholarships. Approximately 45% of these funds are a direct result of the power community.  Unfortunately, the Foundation and SDSU Scholarship Office has not given final approval, and as such we are unable to list our recipients at this time. A post-meeting report will be provided within the minutes, once final approval is given.

  • Internship opportunities -- have a positive impact – absolutely important to the sustainability of the SDSU Power Program
  • Field Trips and the Power Technology Tour – great exposure to a variety of power-related industries
  • CPSS-Sponsored Design Projects – hands on challenging designs
  • Power Systems Analysis and Lab (EE434/434L) -- First course in power
  • Advanced Power Systems (EE 492) – Second course in power
  • Photovoltaics Applications and Lab (EE436/436L)
  • Fall Awards Banquet – A glimpse into the future for our students and shows importance of remaining connected to academia
  • Biennial SoDaRP Conference – An excellent professional setting that introduces power students to the big picture
