I can get behind the green and customer service angles...offering the chargers to attract revenue to your core business, as a great benefit for your employees, and my business being the good corporate citizen. However, In terms of ROI, we can be sure there is a lot more moving parts to this particular deal we aren't privy to.
The case study mentions:
"In the 1.5 years since being connected to the ChargePoint network, the fast charger
has delivered over 2,900 charge sessions for a total electrical output of 18.6 MWh.
In doing this, it has generated more than $10,000 in revenue while adding only
$2,100 to the Marriot’s electric bill (based on the national average of $0.12/kWh)."
So we know there are several stakeholders: ChargePoint, Fuji Electric, EVoasis, and Marriot. While the station may indeed have generated $10K in revenue over 1.5 years, I'd be interested in how this deal came together, what incentives and/or subsidies were offered, and how the revenue (and expenses including others not listed) are distributed. It looks like the deal happened sometime in 2013 as projections were forecasted into 2015
. Worst case, let's assume no growth. If 1.5 years yielded $10K in revenue and $2.1K in expenses, let's assume 3-years suggests a net income of $15,800. I have a tough time believing that a turnkey installation of a 25 kW DC charging station, in 2013
, had an (implied) net cost under $16,000. What parts of this deal were subsidized, and by who? To me, it doesn't add up - again, because we aren't privy to the deal.
While the potential for a 3-year ROI makes for a great press release, based on the other case studies I'm skeptical. Did those rosy projections come to fruition? I'd like to see the historical numbers.
