The Pumpkin is connected to the wires of Ottawa Hydro. They pay us 38.4 cents/kWH for electricity from the solar array. That rate is fixed/guaranteed for 20 years, is paid monthly, and income is tax-free until it pays back the capital cost of the system.

The rates we pay to purchase back electricity vary by time of day and day of week, explained here: https://hydroottawa.com/accounts-and-billing/residential/time-of-use/rate-periods

We expect to bring in between $6000 and $7000 yearly from the system, and pay out perhaps $1200 to run the house. The utility has stated intentions to ramp up their consumption rates to about double current rates within the next few years.

But that increase will likely be more like triple than double, given that the main power generation utility is due to be sold off to private investors over the same period.
