China has a 12 GW 3,300 km (2,100 mi) HVDC transmission line in use for a couple of years now already. That covers South Australian climate to the polar circles. That is of course on the extreme end, but as renewables and storage continue to drop in price the latitude of where it's easily possible will keep climbing towards the poles. This is also why regions closer to the poles focuses on off-shore wind. It is the windiest regions and the windiest months are the winter months. Capacity factors of 60-64% are achieved with the latest 15 MW turbines. Or maybe UK was completely incompetent in allocating 7 GW off-shore wind for £37.5/MWh in the latest CFD round finalized a couple of weeks ago? https://www.gov.uk/government/publications/contracts-for-difference-cfd-allocation-round-4-results https://www.gov.uk/government/publications/contracts-for-dif...
