It’s the other way around, at least in Germany. Households pay more than industry for electricity. https://www.globalpetrolprices.com/Germany/electricity_price...
In Poland I have found that price for companies can be 3x higher based on at least one source. C11 - the tariff for the companies seem to cost 1.6 PLN / kwH [1] G11 - the same tarrif for households seem to cost more like 0.4-0.5PLN / kwH [2]
