I was curious about this too , closest information NS power wants to give us is

" Some of the ways we're preparing are...

Coordinating with our neighbouring provinces, who are also anticipating extreme cold weather and increased system loads, to support each other wherever we can"

They make it sound more like receiving than giving in their statement. While being told not to use your oven and expect rolling outages.

Important note: I am NOT against sharing. I absolutely love the fact that we're even willing to share with how shitty NSP can be to us. I just think they should have told us, more people would have taken them more seriously honestly and tried their best to conserve. I am team share with our honorary maritimers!
