I think the article mostly focused on Manitoba because the current leadership of the province is left-leaning, but as mentioned in the article, it isn't the best place in Canada for panels. With hydro already covering like 95% of the need, I can see dealing with grey skies and snow making solar unappealing.

Saskatchewan on the other hand, is a sunnier province, the snow is way drier here than it is in MB (people in some places in SK use leaf-blowers instead of shovels for all of their snow. You can't do that in MB), it has less population per km^2, and its electricity grid is full expensive expendable resources. And if you don't care about money, and the environment is more your jam, it has the worst pollution to kWh of the provinces, though it does lose to Nunavut if you include the territories.

But, SK has a leader who wants to get relected in a province pretty controlled by the oil and gas industry. So even if Moe could take time away from his busy schedule of bullying children using the notwithstanding clause to look into this, I don't think that anyone in his circle would recommend it.
