Hmm, so basically Sweden has a surplus of goods (electricity), but the EU commissions is trying to pay for it with coupons that look like money but can't be used to buy everything, and now Sweden is saying "no, tak".

Sweden does not have surplus electricity. We have production of electricity that is better matched to demand than other nations, most notably the disaster that is Germany. German demand is causing Swedish industrial production to shut down due to increased energy prices, which makes production unprofitable.
