Energy Usage and Your Bill

Electricity is measured in units called kilowatt-hours, or kWh. The number of kWh you are charged for is determined by your personal usage as read by your electricity meter.

The total amount on your electricity bill comes from 4 costs: your Electricity Use, Delivery, Regulatory, and Debt Retirement charges.

Conserving Energy

Conservation is the cleanest and lowest-cost energy resource and offers you a way to reduce your electricity bill.

If you use less energy at home, there is less need to generate, transmit and distribute electricity. You use less, so your bill is lower and there is less need for new electricity infrastructure.

Where Your Energy Comes From

Your electricity comes from a number of different sources including Nuclear, Natural Gas and various renewables.

The electricity you use in your home is made at a power station and travels through high voltage wires across the Province. A local power utility company turns this power into a lower voltage, safe for your home. The utility company then sends the electricity to you when you need it.
