Last week’s article on the Heartland Transmission Project said the companies did not have to prove the need to build a 500-kilovolt double-circuit power line if that line was designated “critical” under Bill 50. In fact, it’s the Alberta Electric System Operator that has to prove the need for a line. Normally, it has to prove these lines are needed to the Alberta Utilities Commission, often through a public hearing. Bill 50 lets the government bypass this step (as it has for the Heartland Transmission Project) if it is convinced a line is needed. The Gazette regrets the error.
