The DC power lines are larger in diameter than the AC. This is because AC travels in the line and DC travels on the outside of the line. DC does not have the reactance problems (resistance) that AC has so power companies can more exactly meet the actual demand rather than over guess it to prevent outages.
Power companies are looking at a 20% savings in costs adding the same to their profit lines. This 20% would pay for the new power lines 3 times over! But the Conservatives are telling you your power bills are going to go up to pay for the lines.
This is compounded where the cities use the higher chargers either for the electricity or single line charges as a tax bases; this is indirect taxation!
So long as this province is stuck on PC or WRP who are arguably worse, the middle class will continue to take a beating!
