Going OT but:
I'm pretty sure it makes economic sense, but Site C has taken too long to come to the table to get shelved again. This is one of those dam'd if you do, damned if you don't situations
Site C is an inevitable, the energy generated may not be needed now, but it will be if everyone decides to go drive plug-in hybrids tomorrow, or the Cities pull stupid things like banning natural gas in new developments.
The demand will only go up, and despite what you may see on graphs showing no increase in demand, that is due to conservation and smart-meters, not suddenly people using less energy. Your PC of 10 years ago uses the same amount of energy as a new one, but it conserves more energy now when you walk away from it than 10 years ago. Now apply that to pretty much every appliance you buy except for the refrigerator. Take note of various initiatives to improve insulation, replace or seal windows in older buildings, and so forth.
Those conservation efforts will only go so far. One 40 story condo tower likely uses the same amount of electrical energy of the 2 2-story buildings it replaced, but it undoubtedly has gas boilers and high-efficiency water heating that the old building did not. So if the city of Vancouver decides to force new developments to run electricity for all thermal heating, there will be a reversal of conservation effects.
How this translates into Skytrain extensions is that rolling out more electrically powered transportation will increase electricity demand. If you can cut part of your commute with a rapid transit line, then that increases the amount of distance you can go without charging the car. Electric cars are here, we've been asking for them for 30+ years. They are about twice the cost of a ICE-based car, so they will take some time for the costs to come down, or the price of fuel makes running them uneconomical (the maintenance alone on a gasoline car makes them uneconomical once the powertrain warranty is up, so you are likely will have to replace gasoline car twice as often as a electric car, but we don't have those statistics yet, and won't until 2040.)
