This story is one of the best:

Payback in 3 years and $1,000/month in revenue on average.
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.
