Question 1

What is the difference between a CPO revenue model and a charging tariff?

Accepted Answer

A tariff is the price a driver pays per session or per kWh. A revenue model is the full set of income lines a CPO runs — tariffs plus memberships, B2B contracts, demand-response payments and ancillary sales — that together determine whether a site or network is profitable.

Question 2

How much additional revenue can ancillary services realistically add for a CPO?

Accepted Answer

It varies by site type, but industry analysis — including BCG's 2026 CPO research — shows ancillary and platform-based revenue can match or exceed direct energy-sale margin at high-traffic retail and fleet sites, particularly once membership and B2B contracts scale.

Question 3

Do membership models work for public fast-charging or only workplace and fleet charging?

Accepted Answer

Both, with different designs. Workplace and fleet memberships tend to be flat monthly or tiered-usage plans tied to a fixed set of vehicles. Public fast-charging memberships usually offer a discounted per-kWh rate or waived idle fees in exchange for a monthly fee, aimed at high-frequency drivers rather than occasional users.

Question 4

What's the fastest revenue stream for a CPO to add first?

Accepted Answer

Most operators start with a membership or subscription tier for their most frequent existing drivers — it requires no new hardware, layers directly onto existing billing software, and immediately reduces the price sensitivity that erodes session-fee margins.
