Providing solar solutions to British Columbia and New Brunswick
Although in British Columbia BC Hydro changed its policy towards buying the surplus of electricity produced by solar systems in 2018, connecting to BC Hydro still provides lots of benefits to customers. By connecting to BC Hydro, BC Hydro becomes your “private” battery, which will save you thousands of dollars on expensive battery systems.
How that works? Simple. By connecting a solar system to the grid, BC Hydro knows via the smart meter exactly how much electricity you received from BC Hydro and delivered to BC Hydro. The power you deliver to BC Hydro is stored as kWh-credits, which you can use when the solar system does not provide enough energy, for instance, on winter days.
Let me give you an example. In February 2017, an 18 panel 4.5 kW grid-connected solar array was built to create power for a 2400 square foot house. The house used electricity for heating/cooling, hot water, cooking, and all the appliances.
After installing the solar array, the system began to decrease the daily power consumption from BC Hydro significantly. On March 19, 2017, the overall consumption was just 2 kWh.
During July, the medium-sized solar array generated a credit with BC Hydro of 448 kWh. The client only used electricity from the grid for two days.
Even in October, the overall energy consumption was less (3 kWh) than the energy produced by the solar array.
Going into November, BC Hydro’s client had banked 1217 kWh of electricity, which is the rolling difference between the electricity that is produced by the solar array and the electricity that is used by the client.
During November, the client used 514 kWh from the grid, leading to a new balance going into the December billing cycle of a 702 kWh surplus.
As you can see in the November 2017-statement below, the energy charge in November was $0, although the client used 514 kWh of power from the grid.
I hope this example clarifies the way BC Hydro’s Net Metering program is working.
