EV Charging Station Economics: Utilisation, Demand Charges, Pricing & Payback
Measure sessions, kWh and utilisation per charger, estimate charging time by power level, rebuild bills with demand charges, compare per-kWh, per-minute and idle-fee pricing, size a site for its peak hour, budget capex with grants and calculate payback, NPV and break-even utilisation: 8 graded labs for a fictional operator with illustrative tariffs.
The first lesson is free — no account needed.
About this course
An EV charging station economics course that plans the sites of one fictional charge point operator, Larkspur Charge Co., in a spreadsheet, for charging operators, site hosts, fleet and energy managers, consultants and investors. You turn a month of charger logs into kWh per session, time-based utilization and the average power delivered, estimate charging time by power level with a simple DC taper, rebuild electricity bills from energy and demand charges for the true cost per kWh sold, compare per-kWh and per-minute pricing with idle fees, size a new hub for its peak hour with ROUNDUP, budget capex with a capped grant on eligible items, build a 10-year cash flow with NPV and payback, and find the break-even utilization of a DC fast charger. Fictional operator, illustrative tariffs and costs, with no affiliation with any charging network, utility or vehicle brand. The first lab is free.
