The economics certainly don't add up.

Instead of building Site C, Hydro should use the power that BC is entitled to under the Columbia River treaty - over 1,100 MW capacity and 4,000 GWh/yr energy.  But the BC Liberals won't allow it, so instead this power is sold on the market for $30 a MWh, one-third the cost of Site C's energy.

And BC now has smart meters which would allow time-of-use billing to reduce peak loads, further negating the need for Site C.  But the Liberals won't let Hydro take advantage of that either.  

Hydro's debt is spiraling out of control - despite a 46% rate increase from 2014 to 2024, Hydro's debt will grow from $16 billion to $24 billion over the same period.  Clearly not sustainable.
