This presentation to the IESO (Nov. 2021) explains why Ontario should embrace vehicle-to-grid technology that allows us to use electric vehicles to store power in off peak periods and feed it back to the grid in peak periods.
It notes that:
1. EV batteries with bi-directional chargers are cheaper than gas plants for peak power
2. EVs are an enormous opportunity to lower electricity rates & carbon emissions
3. By 2030, EVs will have more than twice the capacity of Ontario’s gas plants
4. When all cars are electric, their gross discharge capacity (GW) will be more than 6
times Ontario’s total peak demand
5. Technical barriers to bi-directional charging have largely disappeared (with more bi-
directional-capable cars and chargers and million+ mile batteries)
6. This is urgent – it is cheaper to incentivize bi-directional charging now before
millions of “dumb” and “one-directional” chargers are purchased
