Probably way more than you think! St. John’s has better solar potential than Tokyo, Berlin, and London, all of which have well established solar economies. And wind, well, we’ve all felt the power there.
The Newfoundland and Labrador Hydro or Newfoundland Power Net Metering Service Option lets customers generate as much electricity as they will reasonably use, while staying connected to the grid. This means that you can install enough solar or wind to cover your entire energy load over the course of a year– and end up paying close to nothing on your utility bill – but you can’t generate a bunch of excess electricity to sell. It’s about saving you money, not running a power plant.
There is also an overall cap of how much you can generate on one site, but this cap is pretty big and only really relevant to commercial or institutional customers – if your home uses over 95,000 kWh/year, you should probably tackle energy efficiency first… The only time we’ve ever come close to this limit with a client was for a double ice rink.
