UIUC's answer to MSU regarding EV charging at UIUC

Posted by Sarthak Prasad on October 30, 2017

MSU asked the following questions of the Big Ten schools.  Here are the UIUC answers, provided by Professor Scott Willenbrock:



Here is information on UIUC.  Most of this infrastructure was put in 3 years ago.  We are now starting to think about where to go from here, so we would appreciate your sharing what you learn from other Big Ten partners.



BIG10 Sustainability Friends,

I am looking for case study information on campus EV charging stations. MSU has several but are looking to expand the service. I have a few questions.

  • How many stations/spaces do have installed on campus? Level 2: 8 spaces.  Level 1: 14
  • How do you charge for use? Level 2: 6 spaces have Chargepoint chargers.  Price is $2/hr for the first 4 hours, $8/hr thereafter.  2 of the spaces are free to visitors of the Institute for Sustainability, Energy, and Environment.  Level 1: Six are free to permit holders, eight are pay spaces ($0.75/hr).
  • How is the cost structured? See above.
  • How do incentivize use? Or regulate use so that only EVs can access? We do not incentive use per se.  The six Level 1 chargers that are free to permit holders are all used daily.   In all spots (Level 1 and Level 2) there is signage that says “EV charging only”, and these are generally respected.
  • Are you measuring how much each station gets used? Level 2 Chargepoint: Yes (see below).  As mentioned above, the six Level 1 that are free to permit holders are used daily.  All other chargers are seldom used.
  • Do you have business model to understand payback on the infrastructure/equipment costs?  No. The installation of the Level 2 chargers was expensive, several tens of thousands of dollars.  We are getting about $100/month of income from them.  Clearly this does not make economic sense.  The Level 1 chargers are free, but the cost of the electricity we are providing is so small as to be negligible.  This may change if we expand access to Level 1 charging.


The last question is the most important.


Thank you,
