Solar panels plus a battery in Coquitlam, does BC Hydro need to approve it?

Yes, BC Hydro approval is required before a grid-tied solar and battery system goes live in Coquitlam. This is not optional and skipping it creates real problems with insurance, interconnection and future home sales.

What BC Hydro's Role Actually Is

BC Hydro is the utility that owns the distribution grid you are connecting to, and any system that can export power or island (run independently during an outage) must go through their interconnection process. You apply to BC Hydro for a Net Metering Agreement before the system is commissioned. BC Hydro reviews the application, may require a site inspection, and ultimately approves the interconnection and installs a bi-directional meter. Without that agreement in place, your installer cannot legally energise the grid-tied portion of the system.

The battery adds a layer of complexity. If the battery is configured to island your home during an outage (which is the main reason most people want one), the inverter must have anti-islanding protection that satisfies BC Hydro's interconnection standards. Most modern hybrid inverters do, but BC Hydro reviews the equipment list as part of the application.

On the permit side, Coquitlam is a Technical Safety BC municipality for electrical permits, not one of the seven cities that run their own program. That means your electrical contractor pulls the permit through Technical Safety BC, and a Technical Safety BC inspector signs off on the installation. The solar and battery wiring, the disconnect, the interconnection point at your panel and any new sub-panel all fall under that permit.

Your contractor will typically handle both the Technical Safety BC permit and the BC Hydro net metering application as part of the job. Confirm this explicitly before signing anything, because some installers treat the utility application as the homeowner's problem.

On cost, a residential grid-tied solar system with a battery in Metro Vancouver typically runs $15,000 to $35,000 installed, depending on system size (kilowatts of panels, kilowatt-hours of battery), roof complexity, panel capacity and how much new wiring is needed between the array, the inverter and your main panel. If your existing panel is a 100A service or is already near capacity, a service upgrade to 200A adds $3,500 to $6,000 on top of that. Get the load calculation in writing before you commit to a system size.

CleanBC does not currently offer a direct rebate for solar panels themselves, but if the system is paired with a heat pump or other CleanBC-eligible equipment, those rebates may apply to that portion. BC Hydro's net metering program credits you for exported power at a rate set by the BC Utilities Commission, so ask your installer to model the payback period using current rates, not optimistic ones.

What a fair quote should include: the Technical Safety BC permit and inspection fee, the BC Hydro interconnection application, all wiring from array to inverter to panel, the disconnect switch required by code, commissioning and a single-line diagram for the inspector. Ask each bidder for their Technical Safety BC contractor licence number and confirm WorkSafeBC coverage before you sign.
