The case
Electro Chargers makes EV battery swap stations and wants to enter one new US city. Which city should it enter, and what fixed investment is required through 2030?
The client already operates in Boston and has shortlisted New York, Washington DC, Seattle, Miami, and Atlanta. Swap stations let drivers replace depleted batteries quickly. Batteries are interoperable across swappable passenger EVs.
