alt Hacker NewsIreland imports less than 10% of it's electricity from the UK. The UK _already_ decommissioned it's coal-based eletricity production. The UK imports roughly 14% of it's electricity, and most of those imports are from nuclear and hydro-electric power.
Your entire comment is incredibly misleading.
No, it isn't. Power in a grid is fungible so grids operate based off consumption-based accounting. Britain continues to import at times from countries still burning coal. As such, Ireland is not free of coal dependence. It's really that simple. It is accurate for Ireland to say she no longer directly burns coal, no longer operates coal power, but the common understanding of "coal-free" is, "we are no longer directly dependent on coal for our lights to turn on." That simply isn't the case.
The way to think about this is, "If the grid had zero reserves and coal cut off, who could POSSIBLY go down?" You may figure this is constructed, but in a few days' dunkelflaute, Ireland needs her interconnects. Wind is then possibly low across much of Europe, meaning Holland and Germany ramp dispatchable capacity, including German lignite.
