This data-file models the economics of electric vehicle chargers. First, we disaggregate costs of different charger types across materials, electronic components, labor, permitting, fees, opex and maintenance (below).
Next we model what fees need to be charged by the charging stations (in c/kWh) in order to earn 10% IRRs.
Economics are most favorable where they can lead to incremental retail purchases and for larger, faster chargers.
Economics are least favorable around multi-family apartments, charging at work and for slower charging speeds.
An economic increment can also be added to reflect the benefits of demand shifting to backstop increasingly renewable-heavy grids.
