The original pipe is 60+ years old, my guess is they are going to slowly replace the pipe in section as a "repair" and not "New pipe", which causes more permit and social unrest headache.

I’d say this is good news but I’m waiting to be told by others why it’s not.

And my pragmatic Danish buddies are at it again.
Thermal storage of electrical energy using molten salt. I liken the concept to a form of renewable geothermal energy.
evidencenetwork.ca
Rather than trying to balance the grid second by second as windmills and solar panels come on and off line and then trying to connect all those individual generators to the grid the concept would be to use the electricity when it is available to pump energy into the ground or, in this case, into a tank of salt. The salt becomes molten and the heat is stored as a liquid at 600C.
That heat can then be used to operate a conventional steam turbine plant to produce electricity with variable loads on demand. It can also be used to heat urban districts.
In an Alberta context two options present themselves.
Given the farflung nature of the windfarms then one option would be to add a salt battery to every farm and pump the heat into the battery whenever the wind blows. If you installed a steam (or ammonia) based generating system on the same site then the grid could draw on the energy when the demand arose.
The other option would be to locate the salt batteries and generating plants in town and use dedicated power lines from the wind farms to keep the batteries fed. The lines would be separate from the grid.

'Systems Thinking' enters the chat
Systems Archetypes & Management Principles
When I read Peter Senge’s “The Fifth Discipline” again, I am very impressed with the three key components that form system archetypes: 1. Reinforcing feedback: These are engines of growth that amplify small changes/ actions to form vicious or virtuous cycles.
