That makes it worse! A euro is worth about 10% more than a dollar.
Ireland has a lot of oil in their power mix from what I'm seeing, so that makes a bit of sense.
Maybe the high power cost is why they're deploying ~600GWh of new wind capacity per year for the last 15 years. Because at those rates the wholesale prices should be able to subsidize a lot of loans.
We don't measure capacity in GWh, we measure it in GW. And if Ireland had 600GW of wind, their entire island would be surrounded by a forest of windmills. Also, Ireland lacks any energy storage so none of that wind can be used for baseload, only variable load.
