Tariff mechanics
You don't need a customer to understand the wholesale electricity market — you need them to understand one simple idea: the price of electricity moves a lot during the day, and a battery lets them buy low and use later.

A current, real example of the cheap-to-peak price ratio on a time-of-use tariff makes the idea concrete rather than abstract — which is exactly the kind of live figure a calculator can surface instead of a static, potentially outdated slide.
Wholesale pricing mechanics, half-hourly settlement, and tariff structure details are interesting but rarely necessary on a first call — most customers only need to trust that the gap is real and that the numbers shown reflect it.
Only if the customer is curious enough to ask — the underlying price-gap concept applies more broadly than any single tariff brand.
The same cheap/peak logic applies to EV charging schedules, which is often a natural next topic once a customer already understands the battery case.
