What's interesting is that they pour money into these alternatives, or worse, refurbish nuclear power plants at a huge cost instead of buying their neighbor's surplus of clean energy. Must be politically motivated!

I thought Quebec had a better trade in selling to New England and New York with its HVDC links: http://www.hydroquebec.com/transenergie/en/reseau-bref.html

electricityMap Live suggests both Ontario and Quebec sell to New York. https://www.electricitymap.org/zone/US-NY-NYIS

But the nature of such links is that they're often saturated if it makes sense to move power - so even if you have 10GW of electricity and New York are willing buyers at the price you offer if there's only 2GW of interconect you can only sell them 2GW of electricity.

As a result it can make sense for Ontario to buy electricity from Quebec and sell electricity to New York, even though Quebec is also selling electricity to New York.

... and NY is selling to OH/PA/etc and they're selling to Indiana and Illinois :)

Dunno if they're re-selling, or if ON/QC pay for the transmission. Dunno how all that works.

My understanding is that they could sell to both and still have surplus.

If I'm not mistaken, there's also unbuilt capacity that could be further expanded if there was a buyer around.
