Would love to know the math on these stations. What does $50K per station cover? How much is the actual DCFC and how much to install? "
The Electric Circuit pays $36,900 for each of its units purchased from AddEnergie thanks to a volume discount. Purchased separately, I think they go for about $44,000 per unit. Other manufacturers' offerings cost a bit less (AddEnergie salesmen will tell you their product holds up better in arctic conditions than competitors' products).
As for installation costs, the Electric Circuit is normally very tight-lipped. They consider it to be a commercial secret. However, in their prior business model the partner-hosts paid most of the costs. When the partners were cities they had make the expenses public and I've seen anywhere from $18,000 to $75,000 for the installation costs on top of the charging station purchase.
Now, the Electric Circuit has a new business model for DCFC where they pay everything. In order to get this model approved they had to go before a public commission to justify their expenses. From that process, we have this table of the costs for sites with single, double, and quadruple stations. (Image attached.)
Note that the installation costs are almost the same for single or double stations. This is because they're installing the room and the infrastructure necessary for a second unit whenever they perform a single installation now. Also, the units being installed are 50 kW ones, but they have said that the infrastructure is future-proofed for higher-power and they will be able to just swap-in higher power stations later. I don't know what the total capacity is per site. Oddly, the installation costs per unit jump from the twin to quadruple stations. This is mostly explained by the canopy the Electric Circuit adds to the quadruple sites. This canopy is too small to protect against the elements and only serves esthetic purposes. (See the attached photo).
So, installations for single stations should be lower if Hydro-One doesn't leave room for second stations.
Installations will also cost less in the short-term if Hydro-QC doesn't future-proof the infrastructure.
Costs can also be slightly less if they buy from ABB or Tritium or whoever instead of from AddEnergie.
Hydro-one can save money by not installing decorative canopies at their 4-station sites.
Construction costs tend to be a bit lower in Ontario than in Quebec.
