Can solar power essentially flatline for a whole day? It did in Alberta on Monday

The Travers Solar Project in Vulcan County was touted by Alberta Energy Minister Brian Jean on Friday, Oct. 20 as the largest in Canada. It has a nameplate capacity of 465 megawatts, and frequently hits that number on sunny days. But that solar facility maxed out at 51 megawatts at 1:16 p.m., according to, which logs data from the Alberta Electric System Operator. That’s 10.9 per cent of its capacity. And most of the day, its output was much lower than that.
