Ireland has essentially no working oil power generation capacity these days (I think the only ones are a couple of small diesel units on islands, which are not even connected to the national grid). Moneypoint was replaced with some combo of wind, gas and imports.

(Moneypoint was actually built originally due to Ireland's over dependence at the time on oil for power generation; after the oil crisis, initially ESB attempted to build a nuclear plant (https://en.wikipedia.org/wiki/Carnsore_Point#Cancelled_nucle...), but it was such a political minefield that it was canceled, leading to Moneypoint.)

Oil stayed more or less steady, so yes, it did.
