Yes they have multiple forms of energy generation, that does not answer the question as to wether their biofuel is sustainable. Yes it's carbon neutral (ish) but can they produce the biomass as fast as they consume it?

The website's number of 500g / kilowatt hour is completely wrong.

This is what BC hydro says:

An efficient, low cost electricity system for B.C. More than 90% of BC Hydro's generation is produced by hydroelectric generation, which is generally the most cost-effective, clean and reliable option. We also continue to investigate alternative sources of energy, such as wind and wave power.

We generate over 43,000 gigawatt hours of electricity annually to supply more than 1.9 million residential, commercial and industrial customers.

Over 80% of BC Hydro's installed generating capacity is at hydroelectric installations in the Peace and Columbia river basins.

About 87% of electricity in B.C. is produced from hydroelectric sources. B.C. is home to roughly 16 000 MW of hydroelectric capacity, most of which is located on the Columbia River in southeastern B.C. and the Peace River in the northeast. Site C, a new 1 100 MW hydroelectric facility, is currently under construction on the Peace River. The project is expected to be completed in 2025.

The greenhouse gas intensity of B.C.’s electricity grid Footnote 2 measured as the GHGs emitted in the generation of the province’s electric power, was 7.6 grams of CO2e per kilowatt-hour (g of CO2e per kWh) electricity generated in 2020. This is a 70% reduction from the province’s 2005 level of 24 g of CO2e per kWh. The national average in 2020 was 110 g of CO2e per kWh (Figure 8).

Actually one comment of many here set me on the right track! I'll reply again when I find out!

Gotta get to the airport now tho, laters!

But nuclear is scalable while running, allowing you to ramp up and down as needed to cover for the intermittent nature of renewables without relying on fossil fuels or similar. Isn't that why adding nuclear into the mix is such an effective strategy?

eyy thank you! That makes sense! You seem to be the only one to actually try to answer my question :/

I know where to look further! thank you!

Yea, that's the issue. For something to be sustainable, you need to replenish the fuel source. Biomass can be, but you need a lot of it, but we also need it for food

Other way round, you can take biomass and turn it into electricity easily. But you cant easily turn electricity into biomass. (it is easy on a phone to go both ways tho, google "USB c OTG adapter")

technically yes, well an accu really. But that might be different in English. The question is whether that sunlight charging of that carbon store can keep up with our consumption
