The grandparent could have done a better job explaining what she meant. You've explained it much better. EU rules forbid discrimination between domestic and EEA customers in electricity markets. Therefore, any significantly interconnected country to the rest of the EU will have similar prices.

Countries like Norway, which have abundant, cheap, generation, are paying EEA prices in its highly interconnected bidding zones (NO1,NO2). The next few months, if prices persist, are likely to see lots of pressure from Norwegians to curtail exports (i.e. close off transmission capacity to EEA). This would significantly decrease prices for Norwegians, but damage the EU's integrity. The same can be said of other countries with abundant, cheap generation that are suffering the consequences of other EEA countries' actions w.r.t their electricity supply.

I say this as a supporter of the EU, but the integrated electricity market's future is in peril this winter.
